Pump Features
1,Low energy consumption
pumps have an extra-high efficiency obtained by the most up to data technical designs,moulding and accurate set up
2,Steady operation
A steep flow curve allows large head changes with minimal rate of flow changes
3,Noiseless operation
Material used,low tip speed of the rotating parts and its ample supports,insure noise and vibration free running
Easy to do,without pump removal;Just remove the electric motor and coumpling
4,Safety
A coupling safety screen avoid accidents
5,Cost-effective
PPO impeller

Minimum inlet pressure NPSH
In case that the pressure in pump is lower than the steam pressure used to convey liquid, the cavitations will occur. To avoid cavitations, a minimum pressure at the inlet side of the pump shall be guaranteed. The maximum suction stroke can be calulated with following formula: H=Pb x 10.2-NPSH-Hf-Hs
Pb=atmosphere pressure [bar] (can be set as 1bar)
In a closed system, Pb means system pressure [bar]
NPSH=Nct positive suction head [m]
(It can be read out from the point of possible max. flow rate shown on NPSH curve)
Hf=Pipeline loss at the inlet [m]
Hv= Steam pressure [m]
Hs= Safety margin=Minimum 0.5m delivery head
If the calculated result H is positive, the pump may run under the max. Suction stroke H.
In case the calculated result H is negative, a delivery head of min.Inlet pressure is necessary.
The following figure shows the limitation of pressure and temperature, which shall be in the scope as shown in the figure.
