Pumps CM and DM - centrifugal, horizontal, cantilevered, single-stage

Pumps CM and DM - centrifugal, horizontal, cantilevered, single-stage
Pump type CM and DM - centrifugal, horizontal, cantilevered, single stage designed for pumping domestic and industrial wastewaters with the hydrogen index: CM - pH from 2 to 13, density 1100 kg/m3, temperature do To ( 90 °C), SD - pH from 6 to 8.5, PhotoStudio 1050 kg/m3, temperature up to + 80 °C, with the contents of various non-abrasive suspended solids, including wood-fibre semi-finished products, concentration of up to 2% by weight, the abrasive suspended solids < 1% by volume, up to 5mm microhardness not more than 9000 MPa.

Maximum gas content in the fluid - 5%.

Pump shaft seal - single face or double sealing with soft padding. In transitional pipe on the suction pipe has a hatch for inspection and cleaning of the entrance to RA-work station of a restorer wheel. Maximum permissible overpressure at the inlet to the pump with mechanical seal - 0.35 MPa (3.5 kgf/cm2), with Salnikov seal - 0.1 MPa (1.0 kg/cm2). The material parts of the flow pump is cast iron. The symbol of the pump corresponds to GOST 22247-96
