Standard Pump motors are designed to operate in the most demanding of environments. An extensive line ofExplosion Proof, TEFC, Open Drip-Proof and Air motors provide durability and safety regardless of the environment.

An air operated diaphragm pump (also known as AODD pump or membrane pump) is a type of positive displacement pump that uses compressed air as a power source. The compressed air is shifted from one chamber to the other by a linked shaft that allows the chambers to move simultaneously. This back-and-forth motion, forces liquid out of one chamber and into the outlet manifold, while filling the opposite fluid chamber via the inlet manifold. Upon changeover, the fluid section that was filled on the previous shift empties into the outlet manifold and the fills the opposite chamber via the inlet manifold. The rapid changeover allows for reduced pulsation at the outlet.

March Manufacturing began in 1954 as a job shop performing precision machining for the aircraft industry.  In 1955, March developed its first pump for removing cooling coil condensation.  Our first magnetic drive pump came out in 1962.  In the late 60’s, March ceased operating in the aircraft industry to concentrate on pumps.

Originally located in Skokie, IL, a suburb of Chicago, March moved in 1968 to Glenview, IL to a larger building to better accomodate the increasing demand for sealless pumps.

The company was founded by William Zimmermann.  Since the beginning, March has been managed by the Zimmermann family, and continues today.

Wilden’s accessory products offer flexibility and value to your liquid process and expand the application range of Wilden pumps by complimenting the performance and specification of your pump. Wilden electronic controllers automate your Wilden pump for batching, and other electronically controlled dispensing applications and processes. By eliminating pump pulsation we can also create laminar process flow, or control the liquid level within a system or process.

DA GLOBAL features thousands of after-market parts IN STOCK in our California-based, 15,000 sq. ft. facility. We specialize in after-market parts for WILDEN®, WARREN RUPP® and ARO®, among others. Large tooling investments allow us to bring forth hundreds of new parts every 6 months, making NOMAD the undisputed leader in its industry.

Air diaphragm pumps are widely used in a variety of applications due to their versatility. Air operated double diaphragm pumps feature few moving parts, with no motor, base plate or other peripherals required. The design style, coupled with its positive displacement functionality, allows for the transfer of shear sensitive products with self-priming up to 25 feet. Air diaphragm pumps feature low initial investment as well as low replacement costs for wear parts when compared to other pump types.

Atex options are available

Wilden®plastic pumps are specifically engineered for maximum performance and efficiency in a variety of applications. In choosing a plastic pump over a metal pump, price, chemical compatibility and mobility come into play. Wilden plastic pumps are lighter compared to metal pumps and therefore easier to transport.The Wilden Advanced Series AODD plastic pump is lighter compared to metal pumps and is easier to transport. When chemical compatibility is critical, plastic AODD pumps provide an outstanding option over metal pumps that are incompatible with certain chemicals. The bolted configuration ensures total product containment optimised liquid path reduces internal friction to maximise output and efficiency. The clamped configuration ensures reliability without sacrificing ease of maintenance. The clamp bands are easily removed for replacement of diaphragms and easy cleaning.

A variety of elastomer options, including Teflon® PTFE, are available to meet abrasion, temperature and chemical-compatibility requirements. The Bolted Series plastic pumps are offered in polypropylene, PVDF and Teflon® PFA. A variety of options, such as ANSI and DIN flanges, and specialised air distribution systems (ADS) are available to meet specific application requirements.
