WSP Booster Pump - Multi Stage Centrifugal

If your water pressure or flow isn’t enough to meet your home’s or facility’s needs, this multi-stage centrifugal booster pump from Water Softener Plus can help. It’s designed to raise water pressure steadily, supporting larger water treatment systems and demanding applications.

The problem you’re facing

Maybe your shower dribbles when other taps are running, or your water treatment equipment won’t operate properly because the incoming pressure is too low. Appliances might take longer to fill, or your irrigation system could struggle to deliver an even spray. Low water pressure or flow means your water just doesn’t come out as forcefully or consistently as you expect.

Why it happens

Water pressure depends on the pump or pressure source supplying your building and the piping delivering water to where you need it. If the pressure isn’t high enough, or the flow rate (how much water moves at once) isn’t sufficient, your fixtures and equipment won’t work at full capacity. This can happen if your supply pump is undersized, your pressure tank is too small, or your system has to push water through complex treatment equipment that resists flow.

A simple test is to measure the pressure at the point of entry or at the treatment system’s inlet during peak water use. If it’s below the recommended level for your equipment, that confirms you need a pressure boost.

What it’s costing you to leave it

Low pressure means your water treatment system can’t work efficiently, which may reduce its ability to help with hardness, taste, or contaminants. Appliances may fill more slowly, wasting your time. Showering and cleaning might feel less satisfying. Over time, your water heater and other equipment can suffer from incomplete or uneven water flow causing inefficiencies. You could also see inconsistent irrigation or longer cycles on pumps trying to compensate.

How this system fixes it

This booster pump uses a multi-stage centrifugal design, which means it has multiple rotating impellers stacked inside. Each impeller adds pressure to the water, so by the time the water exits the pump, it has been steadily pushed to a higher pressure level. This method provides strong, consistent pressure without pushing the pump to extreme speeds, making it more reliable and efficient.

What this system can handle

With a powerful 3 horsepower motor, this booster pump can deliver a flow of up to 20 gallons per minute. That’s enough to supply large reverse osmosis arrays or other commercial and light industrial water treatment systems that need steady, high pressure. Its stainless steel construction resists corrosion, so it can handle treated, high-purity, or aggressive water without wearing out quickly. It’s built for continuous use, making it suitable for bigger setups that run for long periods. This pump fits well on the feed line before your water treatment equipment to ensure it gets the pressure it needs to work efficiently and at its designed recovery rate.

What you actually get

This is a stainless steel multi-stage centrifugal booster pump powered by a 3 HP motor. It’s designed as a stand-alone pump without additional accessories like bypass valves or hoses. The exact installation configuration will depend on your system’s layout and pressure needs, which your plumber will assess.

Is this the right size for you?

This pump suits larger water treatment systems or facilities that require high flow and pressure—think bigger reverse osmosis arrays or commercial setups. If your needs are smaller, such as a single-family home with modest pressure issues, this pump may be oversized. Conversely, if your system demands more than 20 gallons per minute or even higher pressure, you might need to size up to a different model.

Living with it

Maintenance mainly involves ensuring the pump runs with the proper electrical supply and that the suction side is flooded to prevent damage. It’s important to keep sediment and scale away with adequate pretreatment since these can reduce pump life. Running the pump dry or against a closed valve should be avoided to prevent mechanical issues. Regular checks by your plumber will help keep it working reliably. The pump’s stainless steel body and quality design mean it’s built for long service intervals with proper care.

What it won’t do

This booster pump raises water pressure and flow but won’t treat water quality issues like hardness, iron, or taste. You’ll need separate water treatment equipment for those. It also won’t manage complex plumbing problems or fix leaks. If your issue is low pressure from municipal supply limits, a booster pump can help but only up to the limits of your incoming water source.
