Brief introduction

The ZH series horizontal centrifugal pump adopts a double-casing structure, meaning that the pump casing, pump cover and impeller have replaceable metal liners. These parts come in direct contact with the transported media, thus they have extremely high requirements regarding the abrasion resistance of the material.

Therefore, we choose the high chromium cemented carbide (KmTBCr27) as the material for inner wet ends of ZH series slurry pump. Among them, the content of Cr is over 27.5%, with a hardness exceeding 62HRC.

Application

This series centrifugal pump is characterized by outstanding abrasion resistance, making it extremely suitable for transporting slurry with high concentration and strong abrasive solid particles, like mineral sands, coarse tailing, waste sludge, lime mud, etc. In addition, the ZH series horizontal pump can also be used in the chemical industry for transporting corrosive slurry with crystals.

Today, ZH series pumps have been widely applied to ore pulp transportation in metallurgical concentrators, hydraulic ash handling in power plants, coal slurry transporting in coal washeries, river dredging and so on.

Features The metal liners of pump body and cover can be used until worn out without replacement. This prolongs the maintenance cycle and reduces operating cost. The discharge direction of the pump can be oriented to any 8 positions. Bearing assembly adopts cartridge type structure for easy adjustment of clearance between the impeller and rear guard plate. And it can be disassembled as a whole for maintenance. Grease lubrication is used for bearing to prevent the impurities and water from flowing in. Shaft seal is optional in packing seal, auxiliary impeller seal and mechanical seal. This series of horizontal pump can be used in multistage-series to meet requirements for long distance transportation. The bearing assembly is movable to facilitate user adjustment of the clearance between the impeller and rear guide plate. In this way, transporting efficiency can be maintained by narrowing the impeller clearance even the pump is worn out during the operation. Structure

Tips: ZH series pump and ZHR series pump are only different in the material of the lining. But all other components are interchangeable. Clients can choose different materials of linings depending on the working conditions.
