Pentair 6500C 6-roller Spray Pump 22 Gpm 300 Psi Cast Iron

Product Description

The PENTAIR 6500C is a 6-roller spray pump designed for high-pressure fluid transfer in irrigation, spray, and similar fluid-handling applications. The housing is cast iron for durability under sustained operating loads. This pump handles up to 22 GPM with a maximum working pressure of 300 psi and a maximum shaft speed of 1200 RPM. The inlet and outlet connections are both 3/4 inch FPT NPT, simplifying integration with standard threaded pipe runs. The shaft is 416 stainless steel and the seal is a Viton lip seal, which provides resistance to petroleum-based fluids and many chemical solutions. This is a pump-only unit, requiring a motor or drive to be sourced and matched separately. Licensed plumbers, irrigation contractors, and fluid-systems technicians are the typical installers.

The 6500C fits residential and light commercial spray and transfer applications where consistent pressure and moderate flow are required. Its cast iron roller and housing construction suits continuous-duty cycles in clean or lightly contaminated fluid service. The 3/4 inch NPT connections make it compatible with standard pipe fittings found in irrigation manifolds, chemical spray systems, and pressure-boosting setups. Because this unit ships as pump only, the installer selects the motor and coupling based on site requirements and desired operating speed up to the 1200 RPM maximum.

Key Features

• 6-roller design delivers smooth, consistent flow up to 22 GPM
• Cast iron housing and roller material for durability under continuous duty
• 300 psi maximum working pressure suits demanding spray applications
• 3/4 inch FPT x FPT NPT connections for straightforward pipe installation
• Viton lip seal resists petroleum-based and chemical fluids
• 416 stainless steel shaft for corrosion resistance at the drive end

Compatibility

Designed as a pump-only roller spray pump for use with a separately sourced motor and coupling. Compatible with standard 3/4 inch NPT threaded pipe systems in irrigation, chemical spray, and pressure-transfer applications.

Installation Notes

Installation should be performed by a licensed plumber or qualified fluid-systems technician. Shut off all fluid supply and relieve system pressure before connecting or disconnecting any fittings. Ensure the drive motor RPM does not exceed the 1200 RPM maximum shaft speed rating. Follow applicable IPC and local plumbing code requirements for threaded connections, pressure ratings, and fluid compatibility with cast iron and Viton components.
