Pump TsN1000-180 and electric pump units on its basis

CN1000-180 type centrifugal multistage volute-casing pumps and electric pump units on their basis are designed for supply of water and liquids having viscosity and chemical activity properties similar to water, with temperature up to 100 0C, containing solid inclusions by mass not more than 0,05%, size not more than 0,2 mm and microhardness not more than 6,5 GPa (650 kgf/mm2).
The pump type CN is a horizontal centrifugal pump with semispiral inlet and spiral outlets with transfer channels between the stages, with single-entry impellers mounted symmetrically with the main discs facing each other and gland type shaft end seals.
The principle of operation of the pump is to convert the mechanical energy of the drive from an external source (motor) into hydraulic energy of the liquid flow.
Electric pump unit consists of a pump and motor, the shafts of which are connected by means of an elastic sleeve-finger coupling, closed by a guard.
