What are the common spare parts for rubber slurry pumps?
Common spare parts include impellers, rubber liners, pump casings, throatbushes, frame plate liner inserts, shaft sleeves, sealing components, and bearing assemblies. Replacement parts should be confirmed based on the pump model, part number, or technical drawings.
Can rubber slurry pumps be customized?
Yes. Pumps can be configured or customized according to customer-specific flow rate, head, rubber liner materials, sealing arrangements, drive equipment, inlet/outlet orientations, and on-site installation conditions.
What is the difference between CLR, CMR, CMCR, CSPR, and CAHR?
Different models are designed for distinct installation configurations and operating conditions: CLR and CMR are suitable for light-abrasion slurry transport; CMCR is designed for specific heavy-duty slurry conditions such as mill underflow; CSPR is engineered for submerged, pit, or sump slurry handling; CAHR is suitable for rubber-lined horizontal centrifugal slurry pumping applications.
How to select the right rubber slurry pump?
To ensure proper model selection, parameters such as flow rate, head, slurry medium name, solid concentration, particle size distribution, slurry density, operating temperature, pH value, suction conditions, and operating duty cycle need to be provided.
What is the purpose of the rubber lining?
The rubber lining is used to minimize wear and corrosion on the pump casing and wet-end parts caused by certain slurries. It is particularly suitable for slurry applications dominated by fine particles and moderate temperatures. The specific elastomer material and lining structure should be selected based on medium concentration, particle size, operating temperature, and chemical corrosiveness.
What working conditions are rubber slurry pumps suitable for?
Rubber slurry pumps are mainly used to transport solid-bearing mineral slurries, tailings, sand slurries, and other slurries. They are well-suited for mining, mineral processing, grinding circuits, tailings disposal, and general industrial slurry transport applications.
