Piston Pumps

Piston Pumps Have a Long, Long Life

Moving liquids or gases under high pressure calls for piston pumps. Where plants or laboratories require a continuing flow of chemicals, piston pumps are also ideal. Moreover, the design of piston pumps makes them portable and easily adaptable to a variety of uses. Piston pumps are designed to keep on working for a long time, making it possible for manufacturers to issue lifetime warranties on the units they sell.

There are two basic types of piston pumps. One type, known as hydraulic pumps is designed to pump fluids of various characteristics. The other type of piston pumps called pneumatic pumps is intended for moving air and gases.

How Piston Pumps Operate

Piston pumps operate using the basic principle of the piston transferring force from a crankshaft to the piston in order to compress or eject a gas or liquid. The liquid or gas enters a suction manifold into a chamber where it is compressed by a piston and then discharged. Common applications of piston pumps are to power pneumatic drills, blow PET plastic bottles, water pumps, hand pumps and pressure washer pumps such as those used in a car wash.

Because of their relatively simple, rugged construction and design versatility, piston pumps have become a work horse for many industries. They can take a wide range of pressures which can be controlled without affecting the flow rate. If the valves are correctly designed, piston pumps can work with solids, viscous liquids and gases. Changes in the pressure and discharge rate do not adversely affect the performance of piston pumps. With the proper use and maintenance, piston pumps can be a reliable partner for a long, long time.
