Series EHM slurry pump is cantilevered heavy duty Anti-abrasive slurry pump,It is designed for handing strong abrasive, high density and low density, high head slurries. Clients from home and abroad are speak highly of its excellent performance, series EHM slurry pumps have become the first selection in many kinds of working condition.
Series EHR slurry pump is cantilevered heavy duty rubber lined slurry pump, which structure is similar to series EHM pump. But the main difference is the wet parts of series EHR is nature rubber, Chloroprene rubber adhesive and other wear resistant rubber. EHR has better performance in delivering strong abrasive slurry with small particle size than EHM. But we need to pay more attention that EHR can’t be used to transport the slurry with sharp edge.
Series EHM pumps are of double-casing structure, the cover plate and frame plate with replaceable metal lined wear parts (impeller and liners). The outer casing is made of grey cast iron or ductile cast iron according to the working pressure, with split structure and blots connected. The frame plate is connected with the support by bolts.
Series EHR pumps have the same structure with Series EHM pumps. The only difference is that the replaceable wear parts are made of natural rubber and synthetic rubber (impeller and liners). The cover plate, the frame plate, bearing assembly and supports are interchangeable with Series EHM pumps. For all series of pump above, the suction side is of horizontal direction and runs by clockwise from drive end.
EHM(R) Slurry Pump Features:
1. Frame Plate and Cover Plate: The outer casing is made of grey cast iron or ductile cast iron according to the work pressure, with split structure and blots connected, which ensuring security and easy replacement of the wet parts.
2. Wet Parts: Wet parts are the wear parts of pump. The material of wet parts in the pump is high chrome alloy and in good thickness, which make sure the longer lifetime in the same working condition.
3.Shaft Seal: The shaft seal of this kind of slurry pump could use the packing seal, expeller seal and mechanical seal. Expeller seal is standard seal type.
4.Bearing assembly of this kind of High pressure slurry pump use cylindrical structure, adjusting the space between impeller and front liner easily, being removed completely when being repaired. Bearing assembly use grease lubrication.
5.The support and the bearing assembly are designed especially for the slurries transporting. The shaft is of big diameter, good rigidity and short cantilever, which could not bend or vibrate under the server work situation. The bearings could be heavy single or double row tapered roller bearings and cylindrical roller bearings according to different power.
