Johnstone Pump and Pump Repair

Johnstone Pump provides piston pumps for transferring, metering, finishing and dispensing of high viscosity fluids. Air operated or hydraulically operated 2-ball piston pumps, 4-ball piston pumps and chop check piston pumps enable safe operation in spark sensitive environments common in painting applications.

Johnstone Pump can be used with a gravity feed single post lift as a topper type assembly, or with a two post lift as a force feed type assembly for dispensing high viscosity fluids. The lower piston pump is designed for easy priming with double acting feature so material is delivered to the pump discharge outlet on both the up and down stroke.

The Johnstone Pump air motor is connected to the lower pump end by a spacer section. This allows for lubrication of the upper packing gland and prevents motor contamination because of normal wear and eventual leakage through the material packing gland.
