The ZHR series centrifugal pump's impeller, liner, guide plate and other wet ends are all made from rubber material. The abrasion resistance of rubber is lower than high chromium alloy, but it offers good elasticity and corrosion resistance.

This series of slurry pump is especially suitable for the transporting of slurry containing fine particles with no sharp angles, or weak acid, weak base and other corrosive slurry, like ore pulp, ash, cement paste, gravel, etc.

• The materials for flow parts are available in economic natural rubber, polyurethane synthetic rubber with better resistance to wear and corrosion, or other customized special rubbers such as chloroprene rubber. Choose the one based on customer working conditions.
• As for the customers of gold mine, cooper mine and other industries, the medias have higher corrosion and many abrasive particles. So we recommend customers to change the impeller with high chromium wear-resistant alloy material based on rubber liner.
• When the particle content and conveying speed are within a certain range, the natural rubber liner will be more durable than metal or rubber elastic materials due to its better elasticity. Although the comprehensive performance of neoprene is inferior to the natural rubber, it has outstanding abrasion resistance in oils slurry when the temperature is below 200℃.
• The pump casing, cover and transmission parts of ZHR series and ZH series are interchangeable.
• This pump can be installed within multistage pumps.
• The bearing assembly can be removable to bring convenience for customer to adjust the clearance between the impeller and front guide plate. Then the conveying efficiency can be maintained by narrowing the impeller clearance even the pump is worn out during the operation.

Tips: the only difference in ZH series pump and ZHR series pump is the material for the lining. And all the other components are interchangeable. Customers can choose different materials of linings based on the working conditions.
