Horizontal Ring Section Self-Balancing Multistage Centrifugal Pump ZDG6-80X10P for Hot Water
Description
The ZDG series boiler feed pump is a Multistage Ring Section Centrifugal Water Pump, which 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 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. The pump are particularly well suited for hot water transferring and boiler feed applications. Power plant hot water cirulation, Civil heating supply services, Hot water booster service in high building are applications where the pump may be applied.
Generally, a boiler feed pump can handle the pressure of up to 100 bar. In most cases, there is a required pressure for the purpose of your boiler’s operation. It is essential that your chosen boiler feed pump can handle that requirement.
A horizontal multistage ring section pump, can handle pressures of up to 100 bar or 1,500 psig. Aside from boiler feed applications, it can handle operations for agricultural irrigation, desalination and reverse osmosis, pressure boosting systems, natural gas processing systems, and paper mill shower water.
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.
