What jobs are these pumps best for?

Typical applications include irrigation, dewatering and well water transfer.

How does a 300 GPM submersible pump differ from a surface pump?

Submersible pumps go below the surface and are ideal for wells, pits, or deep access points. Surface pumps sit above ground and are easier to access and maintain.

Are these pumps efficient to run long-term?

Yes, most models are designed with high-efficiency motors and flow control options. For high-volume water needs, they’re more efficient per gallon than smaller pumps.

Do the kits include everything for installation?

Yes, RPS kits are designed for quick setup. Most include the pump, motor, fittings, connectors, and detailed installation instructions.

What kind of support is provided after purchase?

Lifetime technical support is included. Our U.S.-based team is available by phone or email to help with sizing, setup, troubleshooting, and maintenance.
