These are pumps assembled in 1.5 body variant. This type of pumps is used in mining industry (reinforced construction) and power plants (respectively cheaper). Our specialists have developed a pump construction that allows prolonging 10 times the time of use of flow parts (full wear to passage washing).

Flow part consists of internal body, rotor (with diameter from 690 to 840 mm), shield disc.

Small diameter pump - characteristic features of the pump:

• 1.5 body variant allowing 100% of use of internal body reserve without risk of damaging the external body;
• reinforced internal body;
• the sealing sleeve made of high-alloyed chromium cast iron;
• modernized bearing assembly.

Large diameter pump - characteristic features of the pump:

• 1.5 body variant allowing 100% of use of internal body reserve without risk of damaging the external body;

• reinforced internal body;

• 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.
