WSP 7 GPM Booster Pump - 1 HP

If your water pressure or flow isn't enough to keep your water treatment system running smoothly, this booster pump helps raise it to the level your equipment needs. It handles up to 7 gallons per minute and supports consistent water delivery in demanding setups.

The problem: not enough water pressure or flow

You may notice your water treatment system isn’t performing well because the water pressure or flow feeding into it is too low. This can mean your reverse osmosis system, softener, or filter isn’t getting a steady, strong flow of water. You might see slower water output, longer wait times for treated water, or inconsistent results from your equipment. When the pressure is weak, your system has to work harder or can’t function properly at all.

Why it’s happening

The issue comes down to the water supply entering your treatment system. Sometimes the pressure from your home’s plumbing or well pump isn’t enough to push water through the treatment stages. Reverse osmosis membranes in particular need steady, elevated pressure to force water through their semipermeable surfaces. If your pump or pressure source can’t keep up, flow drops and performance suffers. A straightforward way to check is to measure the pressure just before your treatment system—if it’s below the level the equipment specifies, a booster pump is needed.

What it’s costing you to leave it

Low pressure or flow means your system can’t produce water at full capacity. Appliances and fixtures get less treated water, and your treatment media or membranes can wear unevenly or clog faster. You’ll spend more time waiting for water and may notice your water doesn’t taste or look quite right. Your water heater, softener, or reverse osmosis unit will run less efficiently, possibly shortening its service life and increasing your detergent or soap use because the water isn’t treated properly.

How this system fixes it

This booster pump raises the pressure and flow rate of your water by using multiple impellers stacked one after another. Each impeller adds pressure, so water leaves the pump with enough force to feed your treatment system steadily and reliably. It works like a pressure amplifier, ensuring your equipment gets the flow it needs to work as intended.

What this system can handle

The pump delivers up to 7 gallons per minute of water at increased pressure, suitable for small to medium-sized water treatment setups. It’s built to handle continuous operation and moderate demands without overheating or failing prematurely. Its cast iron casing and corrosion-resistant internal components make it durable under typical residential or light commercial conditions. Because it’s designed for reverse osmosis and similar systems, it copes well with the steady pressure and flow needs those technologies require.

What you actually get

The pump features a 1 horsepower close-coupled motor in a horizontal layout with a cast iron body for durability. Inside, glass-filled composite impellers and stainless steel bowls resist corrosion and abrasion, while an O-ring seal manages high-pressure operation and simplifies maintenance. It connects with 1-inch NPT fittings on both suction and discharge sides. The design focuses on quiet, smooth running to protect your plumbing and treatment equipment from pressure spikes.

Is this the right size for you

If your water treatment demand is around 7 gallons per minute or less, this pump offers a solid balance of capacity and reliability. For smaller setups with lower flow needs, a smaller pump might be more efficient. Conversely, if your system requires significantly more than 7 GPM, or you have unusually high pressure demands, you’ll want to consider a larger booster pump or a different solution. Proper sizing ensures your system runs smoothly without wasting energy or causing premature wear.

Living with it

Maintenance mainly involves periodic inspection of the wet end seals and bearings, which are designed for easy service without long downtime. Depending on your water conditions and usage, you might schedule service every year or two. The pump is built for continuous operation but should be checked regularly by your plumber to keep it running reliably. Running costs relate mostly to electricity for the 1 HP motor, which varies with usage but is straightforward to budget.

What it won’t do

This booster pump won’t treat water itself—it doesn’t remove contaminants, soften water, or filter particles. It simply increases the pressure and flow to your existing treatment equipment. If your problem is poor water quality rather than low pressure, you’ll need a filtration or softening system to address it. This pump also isn’t a complete water system; you’ll need your local licensed plumber to install it properly and integrate it with your treatment setup.
