DM slurry pump structure

DM 3D Structure

The axially split pump casing is used for pressure bearing and the inner lining is wear-resistant. The metal inner lining has a certain taper in the matching section to ensure accurate alignment during assembly and to ensure that the parts are easy to disassemble or replace. The cast impeller thread is more suitable for slurry pump conditions, and the back blade reduces the sealing pressure and can minimize backflow.

Bearing Assembly

The pump shaft has a large diameter and a heavy-duty cylindrical structure, which is small in size and occupies a small area. Grease lubrication is adopted, so there is no risk of oil leakage, the maintenance is minimal, the rotor is easy to adjust, and it can be used in series.


Packing Seal	Expeller Seal

Packing seal: conventional shaft seal, suitable for various working conditions, can be equipped with special materials such as polytetrafluoroethylene packing, graphite packing, etc., for corrosive or high temperature conditions. Can be equipped with spray-welded ceramic sleeve, suitable for strong abrasive conditions.

Auxiliary impeller dynamic seal: use the pressure seal generated by the impeller and the auxiliary impeller in series, and the packing or lip seal ring is used as the parking seal.

Mechanical seal: internationally leading sealing technology, leak-free sealing effect. Containerized structure, easy installation and replacement, different structural forms are suitable for different working conditions. The friction pair material is made of high-hardness ceramic and alloy materials. The design and matching of mechanical seal and sealing box conform to the flow state of the medium, so it has high wear resistance and shock resistance, and can ensure customer satisfaction under various harsh working conditions.
