network pumps of the SEU type are used in centralized heat supply systems of cities, large microdistricts, where the source of heat is large district boiler rooms, thermal power plants or GT TPP. The design of such pumps allows you to pump coolants with a temperature of up to +180 ° C.
The drive of horizontal centrifugal pumps of the SEU type is an electric motor. The pump and electric motor are installed on separate foundations. The exception is the SEU300-130 pump, which is supplied with an electric motor on a single foundation frame. The pump shaft is connected to the electric motor shaft of an elastic band-plot coupling.
The operating range of pumps of the SEU type: feed from 160 to 2950 m3/h and pressure from 40 to 155 m.
The input and pressure pipes of the pump are located in the lower part of the case horizontally and are directed in the opposite directions perpendicular to the rotation axis. This location of the pipes provides the possibility of disassembling the pump without dismantling pipelines.
The supports of the network pump rotor are bearings on oil lubricant. SEU pumps are made with a double wax or end seal.
