Multistage horizontal centrifugal pumps ЦН type have 2–4 pump impellers. The spiral case of the pump has a horizontal socket. Support of a rotor of the pump are bearings on oil lubricant. The shaft has stuffing box seal.
Shaft of the pump and the completing electric motor are connected elastic finger-muff coupling.
The Symbol of the pump with addition to it of a climatic modification and a placing category in accordance with ГОСТ 15150:
ЦН – the centrifugal pump;
the first figure – supply, m³/h;
the second figure – a head, m;
for Example: ЦН900-310-У3.
