=== APPLICATION ===

Type QD(G) high pressure Stainless Steel Housing Material and Free standing Installation multistage pump swimming pool heater are used for feeding high pressure boiler or pumping high pressure fuel.

The temperature of pumped media is not more than 160ºC.

1)Municipal engineering,Wastewater treatment, constructional engineering 
2)Agricultural irrigation, transfer water etc.
3)High-rise buildings water supply and drainage, and for fire working
4)Factory and mining for distance water supply and drainage
5)Circulation water supply for production process
6)Cooling systems of air-conditioning in hotels
7)Domestic water supply

=== OPERATING TIPS ===

The boiler feed multistage pump is allowed to run within the set parameter range only.

The multistage pump is not allowed to run with the spitting valve closed or closed to a little opening, or it will be caused heated and duration lowered. Each multistage pump is required to run under the special parameters so as to guarantee the flow of it if mounted in a parallel system.

The multistage pump can not run with the suck-in valve closed, or it may be dried moving to cause parts damaged.

The medium the pump transports can not contain air or gas, or both flow and head of the pump may not be accurately measured and, meanwhile, grinding maybe produced to damage parts.

This multistage pump is not allowed to transport any material with grains, or both pump efficacy and part duration may be lowered.

To keep the boiler feed multistage pump in a high effective and stable work, it must be often repaired, the items of repair and the interval between every repair depend on the working condition and running state of it.

 
=== DRIVER ===

Electric motor

The boiler feed multistage pump is driven by the motor through the coupling The gear, membrane coupling and hydraulic coupling can be used according to client's requirements. The pump can be driven by turbine or motor.The rotating direction of pumps are clockwise when viewed from the driving end.
