Some OEMs are listening to customer demands for less expensive products.

The pump, which is available in 10-millimeter (mm) (3/8-inch), 15-mm (1/2-inch) and 25-mm (1-inch) port sizes, is designed for fluid-handling applications that do not require high-end features. Still, the pump has the mass needed for oscillating pumps with wetted parts constructed of PE or PTFE, with conductive versions with ATEX conformity also available, while the diaphragms and ball valves are made of PTFE and ethylene propylene diene monomer (EPDM) rubber.

The pump’s housing parts are tightened against each other via a diaphragm-sized ring on each side. This structure transmits the forces from the housing bolts into the housing parts evenly, which improves the pump’s longevity and increases its safety.

Its air engine has no dead center and operates without the need for lubrication. It has only two moving parts that allow it to achieve superior and volumetrically consistent flow rates and optimize air consumption, which lowers overall operating costs.

The pumps are equipped with separate female national pipe thread (NPT)-threaded inlet and outlet manifolds, while the air inlet is British standard pipe (BSP)-threaded with an optional NPT-threaded air inlet also available.

The pump’s design also positions the suction and discharge ports as separate housing parts. The pump has no drives, rotating parts or shaft seals and features good suction head with self-priming and dry-run capabilities.

These characteristics make it ideal for handling sludges, acids, alkalis, solvents, slurries, emulsions, resins, powders, aqueous solutions and fluids laden with particulates.

It is best in applications such as paints and inks, chemical processing, ceramics, refining, mechanical engineering, textile production, water and wastewater processing, waste disposal, paper production, galvanizing and electroplating.
