Product Details

Horizontal RingSection Multistage Centrifugal Pump DG Series for Hot Water

Description
The Sanchang Type DG Multistage Ring Section Centrifugal Pump is a radially split, segmented casing, multistage pump designed with modular interstage components. These identical components can be assembled to produce pumps of varying numbers of stages, hydraulics, materials, and configurations to meet the customer's specific requirements. Its multiple suction nozzle and discharge nozzle orientations allow the DG pump to adapt to multiple piping installations and provide the piping designer with flexibility in plant layout. Multiple hydraulics for each pump size optimize efficiency across a vast range of applications. All intermediate stage components are identical which reduces spare parts inventory. These pumps are particularly well suited for hot water transferring and boiler feed applications. Civil heating supply services, booster service and other high pressure services are applications where the Type DG may be applied.

Construction
The multistage pump is consisted of stator, rotor, bearing, shaft seal.
1. Stator: consisted of suction casing, discharge casing and diffuser. The casing are held together by external tie rod.
2. Rotor: consist of shaft, impellers, balance disc and shaft sleeve etc.
3. Bearing parts: consisted of bearing housing, bearing and bearing cover. It's generally rolling bearing lubricated by grease.
4. Shaft seal: packing seal or mechanical seal.
