Brief introduction

The ZJ series horizontal centrifugal pump is an upgraded version of both the ZHH and ZH series pumps. The impeller diameter is larger, and the vans are thinner, with ribs on the surface of the pump casing and cover in order to improve the pump stability and durability. This pump series is widely used for handling abrasive and corrosive slurry with solid particles. It is widely used in electricity, metallurgy, coal, building material, chemical and other industries.

Structure
Features

The wet ends are made of high-chromium hard alloy cast iron, and feature a high resistance to wear, corrosion and impact.
The bearing is dilute oil lubricated.
