Pentair 4101C 4-roller Spray Pump 7 Gpm 150 Psi

Product Description

The PENTAIR 4101C is a 4-roller spray pump designed for fluid transfer and spray applications in agricultural, industrial, and commercial settings. Built with a cast iron housing and cast iron rollers, it delivers up to 7 GPM at a maximum working pressure of 150 psi and operates at up to 2600 RPM. The shaft is machined from 416 stainless steel for corrosion resistance, and the pump uses a Viton lip seal to handle a range of fluid types. This is a pump-only unit, installed by irrigation contractors, equipment technicians, and industrial maintenance professionals.

The 4101C fits systems requiring a compact, positive-displacement roller pump with 3/4 inch female pipe thread inlet and outlet connections. Typical applications include sprayer systems, chemical transfer, and light-duty pressure systems where consistent flow and moderate pressure are required. Both the inlet and outlet are 3/4 inch FPT NPT, making integration with standard pipe fittings straightforward. The unit is supplied as pump body only and does not include a motor.

Installation Notes

Installation is typically performed by irrigation technicians or industrial equipment mechanics. Before servicing or mounting, ensure the drive system is fully de-energized and depressurized. Use appropriate thread sealant on all NPT connections and verify inlet and outlet flow direction before final assembly. Do not exceed the rated 150 psi operating pressure or 2600 RPM shaft speed.
