Description
WSP 7 GPM Booster Pump - Cent Cast adds reliable water pressure where your home or water treatment system needs it most. Designed to supply steady flow up to 7 gallons per minute, it supports everyday household demands without struggle.
What You Notice When Pressure Falls Short
Your skin feels tight and uncomfortably dry after showering. Your hair looks dull and lifeless, harder to rinse clean of shampoo or conditioner. Showers sputter or have weak flow, making it harder to wash off soap thoroughly. Filling a large pot or running multiple taps at once slows to a trickle. These are signs your water pressure or flow isn’t keeping up with your household’s needs.
How the Control Head Keeps Water Moving
The heart of this booster pump is a motor combined with a pressure control that senses when water flow is needed. It starts the pump automatically as soon as pressure drops and stops it when demand ends. This “on-demand” operation avoids wasting energy and keeps pressure steady without constant noise or wear. The pump’s multi-stage centrifugal design means it builds pressure efficiently through multiple impellers spinning in sequence rather than relying on a single stage.
What Works Inside the Pump to Boost Pressure
This booster pump doesn’t treat water itself but supports other equipment that does. Inside the pump, water moves through several impellers that add pressure step-by-step. This design suits the steady, elevated pressure required to feed reverse osmosis membranes and ensures your softener or filter works at its best. Its durable cast iron body is built to handle continuous operation without faltering.
Tank and Flow Capacity That Match Your Home
The pump assembly includes a robust housing sized to deliver about 7 gallons per minute of flow. While the exact vessel size depends on your specific installation, it’s confirmed during setup to fit your plumbing and treatment equipment. With a powerful 1-horsepower motor, it maintains steady pressure for typical family use without strain.
Ideal Fit for Average Family Homes
This booster pump suits homes with two to three bathrooms and three to four occupants. It provides enough flow and pressure to keep multiple taps running simultaneously and to feed water treatment equipment that depends on steady input pressure. Larger households or homes with extensive irrigation or high-demand appliances should consider a higher-capacity option. Smaller homes or single-bathroom setups might not require this level of pressure boosting.

Who this size is right for
This is rated for roughly 10 gallons per minute of service flow, which suits an average family home - around 3-4 people with 2-3 bathrooms.
The number to match is peak simultaneous demand, not average use. Two showers and a dishwasher at once is the moment that finds an undersized unit, so size for that.
