WSP 7 GPM Booster Pump - Cent Cast

If your building’s water pressure or flow isn’t enough for your water treatment system to work right, this booster pump helps. It delivers a steady flow of 7 gallons per minute, raising pressure to keep equipment like reverse osmosis membranes running smoothly.

The problem you’re facing

You’ve noticed your water treatment system isn’t performing as it should. Maybe your reverse osmosis unit runs sluggishly or shuts down because the water pressure feeding it is too low. Low pressure means less water flow, so your equipment can’t treat water at the rate your household or facility needs.

Why low pressure happens

Your water source or plumbing setup might not push water hard enough to meet the system’s demands. Pumps built into treatment equipment sometimes aren’t strong enough alone, especially if you have a larger or more complex setup. The key check is to measure the feed pressure entering your equipment—if it falls below what the manufacturer recommends, you’ll see poor performance.

What it costs you to leave it

Low pressure doesn’t just slow things down. It can leave water under-treated and force your system to work harder and longer than necessary. Your membranes or filters may clog faster, and the whole setup wears out sooner. Plus, you’ll spend more time waiting for water or dealing with inconsistent supply.

How this system fixes it

This booster pump uses a multi-stage centrifugal design, which means water passes through several impellers that pressurize it step-by-step. This creates steady, elevated pressure at a controlled flow rate, ensuring your treatment equipment gets the water pressure it needs to work properly.

What this system can handle

Designed for small to mid-sized commercial systems, this pump delivers a reliable flow of 7 gallons per minute. Its cast iron body stands up to demanding, continuous use without wearing out quickly. It’s especially suited for feeding reverse osmosis membranes that need consistent pressure to function efficiently and maintain water quality.

What you actually get

The unit features a durable cast iron construction housing a 1-horsepower motor and a multi-stage centrifugal pump assembly. It’s built without extra components like bypass valves or discharge hoses—you get a focused, reliable booster pump for your water system’s feed line.

Is this the right size for you?

If your system requires up to about 7 gallons per minute and needs a dependable pressure boost, this pump is a strong match. For larger flow needs or higher pressure requirements, you’d want to consider a bigger pump. For smaller setups, a less powerful booster might be more economical and easier to maintain.

Living with it

The pump requires proper installation by a licensed plumber who will size and connect it correctly. Regular checks include monitoring for unusual noise or vibration and ensuring electrical connections remain secure. With routine maintenance, it can serve as a steady workhorse for years.

What it won’t do

This pump does not treat water quality issues like sediment, chlorine, or hardness. It only boosts water pressure and flow. For filtering or softening your water, you’ll need separate treatment equipment installed before or after this pump.
