Slurry pump impeller

Slurry pump refers to a device that converts electrical energy into kinetic energy and potential energy of the medium by means of centrifugal force (the rotation of the impeller of the pump) to increase the energy of the solid and liquid mixed medium. Mainly used in: mining, power plant, dredging, metallurgy, chemical industry, building materials and petroleum and other industries.

The standard material of the auxiliary impeller of the slurry pump is generally gray iron or ductile iron, and it can also be made of A05, the material of the flow parts according to customer requirements. In recent years, most customers prefer the so-called AO5 high chromium wear-resistant alloy material when purchasing. The hydrodynamic seal of the auxiliary impeller refers to the installation of an open impeller in the opposite direction coaxially near the back of the impeller rear cover of the slurry pump. When the pump is working, the auxiliary impeller rotates with the main shaft of the pump, and the liquid in the auxiliary impeller also rotates together. The rotating liquid will generate an outward centrifugal force. On the one hand, this centrifugal force resists the liquid flowing to the mechanical seal and reduces the Pressure at the mechanical seal. On the other hand, the solid particles in the medium are prevented from entering the friction pair of the mechanical seal, which reduces the wear of the grinding block of the mechanical seal and prolongs its service life.
