Highly Reliable Piston Pump with Indirectly Operating Balls

Part of the KOV series which is characterized by its straightforward design and high reliability; the suction and delivery cylinders of this piston pump are connected by indirectly operating balls. Omission of actively driven elements results in a good value pump with the maximum availability. Pasty materials such as mortar or Bentonite, even with a content of foreign substances up to 1” (20 mm) in size can be conveyed without any difficulty with a pumping pressure up to 1305 psi (90 bar) and an output of up to 78.5 yd³/hr (60m³/hr).

Depending on specific individual demand, the balls and valve seats can be supplied in different materials and coatings and a maintenance aperture permits easy and rapid replacement of the valve balls.
