FP (D) Series Centrifugal Pump Feature:
High mechanical strength, strongly corrosion resistance performance
,unique structure,easy operation, safety and no leakage.
It is widely applicable to transport all kinds of corrosive medium
between -40 degrees ~+120 degrees Celsius (PVDF) and -40 ~80
Celsius (RPP) .
The material of pump is made of non-toxic, no pollution, Reinforced
polypropylene (RPP).ABS.UPVC and other injection molding in one
Model No: 50FP D-22

- It must be carefully check all part fasteners whether there is
loose Prior to installation .if loose, must be corrected tighten,
or affect the extraction and vacuum degree.
2. It is must put full water in pooling before start machine , open
pump inlet valve ,
No dehydration idling and inversion, in order to prevent damage of
mechanical seal and pump.
3.Venting or vacuum to town down to 0.092Mpa below before stop ,
and then shut down to prevent vacuum degree is high ,but back
suction damaged check valve, (such as check valve malfunction,
please open the valve cover, remove debris).
4.Gas water cascade jet pump, and start machine in advance , then
open the steam ,close up steam at frist, then shut down to prevent
damage to water injection pump. In the installation of steam
piping, guarantee the pipeline is not contained water,must maintain
a certain level, otherwise it will affect the degree of vacuum.
5.Pool Circulation water temperature is too high, it will affect
the exhaust quantity and vacuum degree, need timely replacement or
6. With reference of special full sealing pump set , it is must be
assembled an exhaust outlet ,otherwise it will make water tank
compression deformation and rupture .
The mainly reasons to affect Vacuum degree
1. Check up water tank level and water temperature . If the water
level is over lower , water temperature high , it will affect
vacuum degree .
2. Check up water pump whether have odds and end inhale. It will
affect vacuum degree . if water pump and inlet pipe have odds and
3. Mechanical seal leaking will impact vacuum degree .
- Water jet pump nozzle wear and tear or deformation will impact
vacuum degree .
- Unsteady Voltage will influence vacuum degree , it may induce
back-suction water in vacuum tank .
- Valve ,cut-off valve wear and rear will air leak , pipeline is over
long ,air leak will influence vacuum degree .
