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...
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, the velocity will then be...
A metering pump is a precision machine that moves or pumps a measured amount of fluid in a predetermined time to create volumetric flow. The term “metering pump” covers a wide range of pumping methods, each designed to meet the needs of...
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...
A ball valve is a shut-off valve that allows or obstructs the flow of liquids and gases in a piping system by rotating the ball having a bore inside the valve for 90°. The ball is mounted against two seats and has a stem that connects it to the operating and control mechanism that rotates the ball...
A butterfly valve is a quarter-turn rotational motion device that utilizes a rotary disc to allow, obstruct, or control the flow of fluids in a piping system. It features a rotating disc that is situated on the passageway of the flowing media...
A check valve is a safety device designed to allow fluids and gases to flow in one direction. Under pressure, fluids enter the valve at the inlet and exit through the outlet. Uninterrupted flow continues until the pressure drops, or the pump is shut down...
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...
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...
