The given pump type is used in mining industry. Characteristic feature of this pump is separately made part of "body" and "pressure disc” as well as separately made "suction disc" and "suction port". Such construction ensures maximum longevity in especially difficult conditions of use.
The pump flow part includes: body, rotor (we produce rotors with various diameters from 690 mm to 840 mm), suction disc, pressure disc, suction port.
Characteristic features of the pump:
-
1.5 body assembly variant allowing 100% of use of internal body reserve without risk of damaging the external body;
-
reinforced body;
-
reinforced pressure disc;
-
separately made suction port;
-
the sealing sleeve made of high-alloyed chromium cast iron;
-
modernized bearing assembly;
-
modernized and reinforced stand (bracket, bearing assembly) with 3 stage bearing assembly cooling and increased volume of the oil pan.
