Diaphragm liquid OEM pump; Source: KNF Neuberger, Inc.Washing machines are found in nearly every household and their reliable operation is something most owners take for granted. One of the most important components is the drain pump. The drain pump is integrated into the design of the washing machine by the original equipment manufacturer (OEM). Without it, the water won’t drain and the homeowner will be cleaning up a flood.

The washing machine drain pump is an example of an OEM pump -- a class of pump manufactured for use by original equipment manufacturers as part of a system sold to end users. Reliability and quality are important factors for OEM pumps as the system is only as good as the weakest component.

In addition to appliances, OEM pumps are found in equipment for a wide range of applications, including medical, packaging, environmental, agricultural, analytic instruments, HVAC, security and defense and the printing industry. Types of OEM pumps are as varied as the applications for them and include peristaltic, diaphragm, solenoid, dosing, centrifugal, rotary gear, piston and plunger pumps. OEM pumps are also manufactured to operate with air, gas, and various types of liquid media.

OEM pump accessories; Source: KNF Neuberger, Inc.Systems manufacturers typically purchase OEM pumps in quantity. In some cases, pumps can be furnished with motors and controls, valves and other accessories, and installation kits to help simplify system integration demands. Although most manufacturers offer a standard line of OEM pumps, some will also design custom connections and mounting solutions or possibly a new pump that is optimized for the system.

OEM pumps are manufactured to maximize application possibilities. In addition to reliability and quality construction components, additional features may include chemical resistance, mounting arrangement flexibility, non-corrosive materials, light-weight materials, long service life, low sound and vibration levels and a maintenance-free design. Some pumps may also be available in a wide variety of materials to suit any application. To meet systems manufacturer’s requirements, OEM pumps, motors and other components typically conform to common standards such as ISO, ANSI and UL.
