Product Description

Oil resisting high lift musti impeller hot oil booster pump

=== OVERVIEW ===

General overview about Oil resisting high lift musti impeller hot oil booster pump

Model DG Stainless Steel Housing Material and Free standing Installation heat pump swimming pool heater is a horizontal multistage centrifugal boiler feed pump and suitable for transporting liquid (with the contained foreign matters' content less than l % and graininess less than 0. 1mm) and other liquids.

QDG model middle and low pressure boiler fuel pump is applicable to transport medium with temperature of not higher than 105oC, and is also applicable for small boiler water supply or transporting medium similar to hot water.

QDG model hypo high pressure boiler water supply pump is used to transport medium with temperature of not higher than 160oC, and is also applicable for small boiler water supply or transporting medium similar to hot water.

 

=== APPLICATION ===

=== PARAMETER === 

Peformance parameter about Oil resisting high lift musti impeller hot oil booster pump

Range of capacity: 120-1100m3/h

Range of total head:967- 2500m

 


The second time, both pump and motor are secured while the bolts on the suck-in and spitting pipeline flanges are not.

The third time is in 24 hours after the pump starts running,then secure both pump and motor

 

=== OPERATING TIPS ===

Attentions when operate Oil resisting high lift musti impeller hot oil booster pump

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

The 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 pump is required to run under the special parameters so as to guarantee the flow of it if mounted in a parallel system.

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

To keep the boiler feedwater 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.
