Choose this FMC John Bean R20 Single Shaft Pump for use in your sprayer assemblies. This product features a cast iron case, and you get extra durability and performance because of its non-wearing ceramic cylinders. Count on reliable functionality with its positive-action disc-type hardened stainless steel valves and oversized ball bearings. Finally, its spring-loaded seals work to ensure that oil stays in and dirt stays out of the mechanism.
