Graymills is experienced in moving & conditioning liquid, as well as manufacturing centrifugal pumps since 1953. We offer many centrifugal pump varieties including vertical immersion sump pumps in single or multi-stage configurations, self-priming pumps, sealless pumps, flange mount centrifugal pumps, water pumps, submersible pumps, & stainless steel centrifugal pumps for industrial applications.
A centrifugal pump is defined as a hydraulic machine that changes mechanical energy into hydraulic energy by the use of centrifugal force acting on the fluid. This is a machine that uses rotation to enforce velocity on a liquid...
A metering pump is a precision mechanical device that moves or pumps a measured amount of a fluid or liquid in a predetermined time period to create an accurate and exact volumetric flow...
A vacuum pump is a piece of equipment capable of generating a partial vacuum or a low-pressure space by drawing gas molecules out of a sealed chamber. A vacuum is a relative state at which the chamber pressure has...
Battery powered sump pumps are very similar to any of the other types of sump pumps. When the water level reaches a preset level, the pump is activated by the float and water is pumped out. The main difference between a regular sump pump and...
A PVC or polyvinyl chloride ball valve is a plastic on and off valve that has a rotary ball with a bore where turning the ball a quarter turn can stop the flow of a fluid. They are highly durable, cost effective and can be...
Rotary vane vacuum pumps are vacuum pumps that generate low-pressure zones by rotating the moving parts against the pump casing. The mating surfaces of the rotor and the housing have very...
