ZAO pumps Adopt the foot support and open or semi-open impeller, with design pressure of 2.5Mpa, applicable to conveying all kinds of residue slurry and mediums containing particles. (API610 OH1 pump type) The hydraulic power of the series pump, selected from and improved on the base of excellent hydraulic models, enlarges the inlet caliber of pump impeller, lowers the flow rate at inlet, enhances the anti-cavitation performance and working efficiency, increases the corrosion margin of pump casing and impeller, and prolongs the service life of pump.

Standard modularization design

The back pull-out design enables the bearing pedestal including impeller and shaft seal to be removed with the volute casing left in position

Shaft sealed by cartridge mechanial seal + API flushing plans ISO 21049/API682 seal chamber accommodates multiple seal types

The pumps with outlet diameter bigger than DN 80 (3”) are provided with double volute casings

High radial load roller bearing. Back-to-back angular contact bearings handle axial loads

ZAO/ZEO open impeller and adjustable bearing carrier easily allow impeller clearance adjustement for high hydraulic efficiency and slurry applications

The pump rotation is clockwise viewing from the drive end
