Series overview
ZD and ZDG are horizontal single-suction segmental multistage pumps with a self-balancing axial-thrust arrangement covered by six national patents. The design gives high efficiency over a wide performance envelope, stable and quiet running, long life and straightforward maintenance.
They handle media containing solid particles smaller than one quarter of the impeller passage. By changing the wetted material, the seal arrangement and the cooling system, the same series can be adapted to hot water, oil, corrosive liquids and abrasive media.
