Why Choose the Hydro-Logic Continuous-Duty Booster Pump

Hydro-Logic markets this unit as a "work horse pump," and the engineering choices behind that label are deliberate. Most consumer-grade booster pumps sold for residential RO systems are intermittent-duty pumps that rely on internal thermal-cutoff cycling to protect the motor from overheating during prolonged runtime. That behaviour is fine for a small under-sink RO that runs for a few minutes per fill. It is incompatible with commercial cultivation use, where an Evolution-RO 1000 or 1500 system may run continuously for hours each day to fill large reservoirs. The Continuous-Duty pump is designed to address exactly that gap, with several specific design choices:

• Does not thermally cycle. The motor and pump head are sized for sustained operation rather than burst use. The unit can run for the full duration of an RO fill cycle, then restart automatically on the low-pressure switch, without thermally cycling the motor offline. For commercial growers running unattended overnight or weekend fills, this is the single most important behavioural difference between this pump and a generic booster.
• Integrated dual pressure switches. A low-pressure switch on the inlet side cuts the pump off if upstream supply drops below the 20 psi minimum, protecting the pump from dry-running. A high-pressure switch on the outlet side cuts the pump off when downstream pressure is satisfied (for example, when a float valve closes on a full reservoir). The two switches together provide automatic start-stop control without a separate pressure tank or controller.
• No Electronic Shutoff Kit needed with a float valve. When paired with the Hydro-Logic 3/8 in. float valve on a reservoir, the high-pressure switch alone is enough to stop the pump on tank-full; the Electronic Shutoff Kit that some Evolution-RO configurations require is not needed. This reduces the bill of materials and simplifies wiring.
• Adjustable pressure dial. Output pressure can be tuned with a turn-screw on the pump head. For RO membranes, higher applied pressure improves rejection rate and permeate flow up to the membrane's rated maximum. The dial lets the operator dial pressure to the membrane's sweet spot rather than running flat-out at 80 psi regardless of duty.
• 110V plug-in, no hardwiring. The pump arrives with a standard 110V cord and plug. Installation does not require an electrician, conduit, or junction-box work; it plugs into any standard 15A residential or light-commercial outlet. This dramatically reduces install cost compared to hardwired commercial pumps.
• Included pump protector and quick-connect fittings. A sediment / particulate inlet filter (the "pump protector") is included, which protects the pump head from grit that can damage internal seals. 1/2 in. quick-connect fittings on the inlet and outlet mate directly to standard Hydro-Logic Evolution-RO tubing, so plumbing is push-to-connect rather than threaded.
• Commercial reliability heritage. Hydro-Logic Systems positions itself as "The Industry Leader in Commercial Reverse Osmosis," with the Evolution-RO, Stealth-RO, Tall Boy, and HyperLogic product lines all targeting commercial cultivation. The continuous-duty booster is the pump they spec for their own larger RO units, so component compatibility with the rest of the Hydro-Logic ecosystem is engineered in rather than improvised.

Best Uses for the Pressure Booster Pump

This pump is built for one job: lifting feed-water pressure to a commercial reverse osmosis system that needs more than the local municipal hose-bib pressure delivers. The scenarios below are where commercial growers most often deploy it.

• Boosting feed pressure for Evolution-RO 1000 / 1500 systems on low-pressure supplies. Hydro-Logic Evolution-RO commercial units perform best with feed pressure at the membrane in the 60 to 80 psi range. Many municipal residential hose taps and well-pump pressure-tank systems deliver only 30 to 50 psi at the spigot. Inserting the booster pump upstream of the RO inlet lifts feed pressure to spec, which improves both permeate flow rate (gallons-per-day actually produced) and membrane rejection rate (purity of the RO output).
• Commercial cultivation reservoir fills. Commercial cannabis, vegetable, and ornamental growers running large reservoir or tank-fed irrigation programs benefit directly from faster RO production. A 1000 GPD system fed at 30 psi often delivers nowhere near its rated output; the same system fed at 70-80 psi typically delivers closer to its nameplate rating. For a grower filling 100+ gallons of reservoir per day, that is the difference between an overnight fill and a 36-hour fill.
• Multi-zone reservoir networks with float-valve control. When the booster is paired with a Hydro-Logic 3/8 in. float valve on each reservoir, the high-pressure switch handles automatic stop-on-full without needing the Electronic Shutoff Kit. This is a clean automation pattern for a multi-tank room: the booster pumps continuously until every float closes, then idles on the high-pressure switch until any single float drops.
• Boosting third-party commercial RO units up to ~150 psi rating. The pump is also compatible with non-Hydro-Logic commercial RO systems that accept up to roughly 150 psi feed pressure. (Always verify the membrane's maximum feed pressure spec before installing.) The 1/2 in. quick-connect fittings can be adapted to compression or NPT fittings with standard adapters.
• Wells and cisterns with weak pressure-tank output. On well-supplied properties where the pressure tank delivers acceptable volume but inadequate pressure for an RO membrane, a downstream booster pump is the standard fix. The Continuous-Duty unit is well suited to this duty because well-fed RO systems typically run long fill cycles.
• Pairing with an aerated mix reservoir. Once filtered water reaches the reservoir, it is commonly aerated and conditioned before use. An air pump such as the Active Aqua 1 air pump with 8 outlets keeps dissolved oxygen up across multiple stones in larger reservoirs while RO continues filling.

Continuous-Duty Booster vs Standard Booster Pumps and Alternates

The commercial RO booster-pump category splits roughly into three groups: continuous-duty commercial boosters (this Hydro-Logic unit, GrowoniX high-pressure booster), intermittent-duty residential boosters bundled with under-sink RO systems, and low-voltage variants designed for off-grid or DC-powered installations. Picking the right group prevents both overspending and burning out a too-light pump.

Continuous-Duty 110V vs the 24V / Low-Voltage variant. Hydro-Logic offers this same pump head in a 24V low-voltage variant intended for installations where 110V wiring is undesirable or where the pump is driven from a low-voltage controller. For most commercial growers in standard 110V North American buildings, the 110V plug-in version covered here is the right pick because it requires no transformer, no controller wiring, and no separate DC supply. The 24V variant is the right pick only when the installation is genuinely low-voltage by design.

Continuous-Duty vs GrowoniX High-Pressure Booster. GrowoniX produces an alternate commercial RO booster pump targeting overlapping use cases (boosting feed pressure to commercial RO units). The two units are close peers in terms of duty rating; the decision often comes down to which RO ecosystem you are running. If the rest of the system is Hydro-Logic Evolution-RO, this pump's 1/2 in. QC fittings and float-valve compatibility make it a direct drop-in. If the rest of the system is GrowoniX, the GrowoniX-branded pump may be the simpler integration.

Continuous-Duty commercial vs residential under-sink booster pumps. Generic residential booster pumps sold in 50 to 100 GPD under-sink RO kits are intermittent-duty pumps that rely on thermal cycling. They are typically rated for cumulative on-time of a few hours per day; running one on a 1000 GPD commercial reservoir-fill load will cause it to thermal-cycle off mid-fill and, over time, will burn out the motor. The Continuous-Duty unit is the appropriate tier for commercial reservoir fills, even though it costs several times what a residential booster does. For low-volume duty (a single small RO unit doing 75 GPD or less), a compact appliance like the Hydro-Logic Micro 75 GPD reverse osmosis system may not need a separate booster at all when fed from a typical residential pressure supply.

Sediment pre-filtration upstream. Whichever booster you run, sediment in the feed water shortens pump-seal life by accelerating wear on the internal pump head. The included pump-protector inlet filter handles fine particulate, but on supplies with heavy sediment loads it pays to add a coarse pre-strainer ahead of the pump. A standard mesh-screen filter such as the Dilution Solutions 1-1/2 in 200 mesh filter is the conventional upstream protection on a larger irrigation header.

Compatibility & Operating Range

The Hydro-Logic Pressure Booster Pump is intended for inline service upstream of a commercial reverse osmosis system. The notes below come from Hydro-Logic Systems documentation and supplier listings.

RO system compatibility: Primary fitment is the Hydro-Logic Evolution-RO commercial line (Evolution-RO 1000 and Evolution-RO 1500). The pump is also compatible with other commercial RO units that accept up to roughly 150 psi feed pressure on the membrane side; always confirm your specific membrane's rated maximum feed pressure before installing, and adjust the booster's pressure dial down from 80 psi if needed.

Plumbing connections: 1/2 in. quick-connect (QC) fittings on inlet and outlet, sized to mate directly with standard Hydro-Logic Evolution-RO tubing. For non-Hydro-Logic systems, 1/2 in. QC-to-NPT and QC-to-compression adapters are readily available; do not over-torque on plastic QC fittings.

Electrical requirements: 110V AC, 7.8 amps. Plugs directly into a standard 15A North American outlet. Do not run on the same circuit as other high-draw equipment if continuous operation will be needed; a 7.8A continuous load is roughly 60% of a typical 15A breaker's continuous-load allowance, so a shared circuit with a dehumidifier or HVAC compressor can trip the breaker.

Feed-pressure window: Requires a minimum of 20 psi inlet pressure to operate; the low-pressure switch will cut the pump off below that threshold to prevent dry-running. Maximum output is 80 psi, adjustable via the pressure dial on the pump head. For most Evolution-RO installations, dialling output to 65-75 psi gives a strong balance of permeate flow and seal life.

Float-valve and shutoff compatibility: Designed to work with the Hydro-Logic 3/8 in. float valve on a reservoir. With a float valve installed, the high-pressure switch alone handles automatic stop-on-full and the separate Electronic Shutoff Kit is not required. Without a float valve, the Electronic Shutoff Kit is the conventional automation; consult Hydro-Logic Systems documentation for that wiring pattern.

Environmental limits: Indoor service in a climate-controlled space. Do not install in a freeze-prone outdoor enclosure; residual water in the pump head can crack the housing when frozen. Keep the pump clear of standing water on the floor; the 110V plug-in is not rated for wet locations.

Water-chemistry compatibility: Cold tap water service, with chlorine, chloramine, sediment, and typical municipal-supply chemistry. Do not feed hot water through the pump. For hot-water or chemically-aggressive feeds, contact Hydro-Logic Systems for the appropriate alternative.

Usage Guidelines

This pump is designed for set-and-forget continuous operation once it is correctly installed and dialled in. The guidelines below cover commissioning, routine running, and long-term care.

Commissioning the pump. Before the first long fill cycle, run the booster for several minutes at moderate pressure to verify that the pressure switches engage and disengage cleanly and that there are no leaks at the QC fittings. Confirm the pump-protector inlet filter is seated and that no air is trapped in the pump head; a small amount of cracking-flow can be expected on first start as air clears.

Setting the pressure dial. Start with the dial in a mid-range position and observe the permeate flow rate at your RO system's flow meter. Increase pressure incrementally up to the membrane's rated maximum (typically 80 psi for Evolution-RO; do not exceed your membrane's spec). Higher pressure raises both permeate flow and rejection rate up to a point. There is no benefit to running above the membrane's rated pressure, and exceeding it shortens membrane and seal life.

Routine operation. The pump is automatic. When upstream supply is present (above the 20 psi minimum) and downstream demand exists (float valve open, RO drawing water), the pump runs. When the high-pressure switch sees a satisfied downstream (float closed), the pump shuts off and waits. There is no manual on/off cycle required for normal use, but the 110V plug should be removed during long-term shutdown or maintenance.

Pre-filter and pump-protector maintenance. The included pump-protector inlet filter is a sacrificial sediment screen and will eventually clog with debris from the feed line. Check it during routine RO sediment-prefilter changes (typically every 3-6 months in commercial use). If you see falling permeate flow despite clean RO sediment prefilters, the pump protector is a common culprit and an easy diagnostic step.

Monitoring duty and noise. The pump should run smoothly without vibrating-rattle or surging noise. A change in audible character (sudden vibration, intermittent surging, or rapid switch chatter) usually points to either a feed-pressure problem (supply dropping near the 20 psi cutoff), an air leak on the suction side, or a worn pressure switch. Investigate sound changes promptly; running a stressed pump for long periods accelerates seal wear.

Storage and seasonal shutdown. For seasonal shutdown in an unheated space (typical for outdoor cultivation operations winding down for winter), disconnect water at both QC fittings, drain the pump head fully, and store the pump indoors above freezing. Leaving residual water in the pump head through a freeze cycle is the most common cause of housing damage on out-of-season units.

Service life and replacement. Used within its rated duty (continuous service on Evolution-RO feed water with the included pump protector) the unit is expected to deliver multi-year service before requiring rebuild or replacement. Sudden loss of pressure, persistent leakage, or motor failure under normal load indicates end-of-life and a replacement should be sourced before the next high-demand fill cycle.

How to Install the Booster Pump on an Evolution-RO System

Installation is straightforward and typically takes 15 to 30 minutes for a grower already familiar with quick-connect tubing. The numbered steps below cover a standard Evolution-RO retrofit.

1. Shut off the feed water and depressurise the line. Close the upstream feed valve to the Evolution-RO system. If the RO has been recently running, open a downstream tap or drain to relieve residual line pressure before disconnecting any fittings.
2. Identify the pump's inlet and outlet. The pump housing is labelled with flow-direction arrows. The inlet (with the pump-protector / inlet filter) connects to the upstream feed line; the outlet connects to the Evolution-RO inlet.
3. Choose a stable, level mounting location. Place the pump on a level shelf or floor pad in a dry, indoor location near the Evolution-RO unit and within reach of a standard 110V outlet. Avoid mounting on a vibrating surface; rubber pads under the pump base reduce noise transfer.
4. Confirm and seat the pump-protector inlet filter. Verify that the pump-protector (inlet filter) is installed on the inlet side and that its housing is hand-tight. The pump should never be run without this filter in place, even briefly.
5. Connect the inlet QC fitting to the feed line. Insert the 1/2 in. feed-line tubing fully into the inlet quick-connect fitting until the collet locks. Tug gently to confirm the line is seated; tubing that pulls out has not seated correctly.
6. Connect the outlet QC fitting to the Evolution-RO inlet. Run a length of 1/2 in. tubing from the pump's outlet QC to the Evolution-RO unit's feed inlet. Keep the run as short and straight as practical to minimise pressure drop. Confirm both QC joints are fully seated.
7. Wire the float valve (recommended). If using a Hydro-Logic 3/8 in. float valve on the reservoir, install it on the reservoir outlet line per the float-valve instructions. With a float valve in place, the high-pressure switch handles automatic stop-on-full and no Electronic Shutoff Kit is needed.
8. Plug into a 110V outlet. Plug the pump cord into a standard grounded 110V outlet on a dedicated 15A circuit, or a circuit not shared with other high-draw equipment. Do not use a light-duty extension cord; if an extension is unavoidable, use a 12-gauge or heavier cord sized for the pump's continuous 7.8A draw.
9. Restore feed water and inspect. Open the upstream feed valve slowly. The pump will start when the low-pressure switch sees adequate inlet pressure and downstream demand. Inspect all QC joints and the pump head for leaks. Tighten or re-seat any joint that shows drips.
10. Dial in operating pressure. With the system running and the RO drawing water, observe the pressure dial and Evolution-RO permeate-flow meter. Adjust the pressure dial upward in small increments until permeate flow stabilises near the membrane's rated output, without exceeding the membrane's maximum feed-pressure spec.
11. Verify automatic shutoff. Allow the reservoir or downstream container to reach full. Confirm that the high-pressure switch cuts the pump off cleanly when the float closes (or downstream demand otherwise ends). The pump should restart automatically when demand returns.
12. Label the install date. Mark the install date on the pump housing or in a maintenance log. Schedule the first pump-protector inspection at the same interval as the Evolution-RO sediment-prefilter change.
