Remco RollMax R441C 4-Roller Pump - Cast Iron, CW, 1/2" Hollow Shaft, 9.4 GPM

The Remco RollMax R441C is a professional-grade 4-roller positive displacement pump designed for agricultural spraying, liquid transfer, and industrial chemical application systems. Delivering up to 9.4 GPM at pressures up to 150 PSI, the R441C combines reliable flow performance, rebuild-ready serviceability, and durable cast iron construction for demanding field applications.

Built with a black epoxy-coated cast iron housing, hardened stainless steel shaft, Viton seals, and permanently lubricated bearings, the R440C is engineered to handle continuous spraying operation across a wide range of agricultural and industrial applications.

One of the major advantages of the RollMax platform is its Rebuild Ready design. When rollers wear over time, operators can typically service the pump directly in the field using only basic hand tools without disconnecting plumbing or removing the pump from the drive shaft. This helps minimize downtime and simplify routine maintenance during peak spraying season.

The 4-roller pump design delivers smooth, consistent fluid transfer with reduced pulsation for reliable spray coverage. Its clockwise rotation, 1/2" hollow shaft, and standard 3/4" FNPT ports allow straightforward integration into PTO-driven and gas engine-driven spray systems.

For operators looking for a dependable commercial roller pump with simple field serviceability and proven spraying performance, the Remco RollMax R441C is built to handle demanding spraying and transfer applications.

What does “Rebuild Ready” mean on the RollMax series?

The RollMax Rebuild Ready design allows common wear components like rollers and seals to be serviced directly in the field without removing the pump from the shaft or disconnecting plumbing.

What is the maximum flow rate of the R441C?

The R440C produces up to 9.4 GPM at 2600 RPM open flow conditions.

What direction does the R441C rotate?

The R440C is configured for clockwise (CW) rotation.

When should you choose the cast iron R441C vs the stainless steel R440SS?

The R440C is commonly used for general agricultural spraying applications, while the stainless steel R440SS is preferred for more corrosive chemical environments.
