Double suction design for large capacity

Product Features:

1. A wide range of transmission medium, with allowable certain amount of impurity in the medium;

2. Double layers of structure design, with comprehensive heating and thermal insulation for medium, as well as sufficient and rapid heating;

3. A variety of bearing cooling modes available, with better protection of bearing and prolonged service life;

4. Optimized structure design, with allowable short period of dry operation (≤2min);

5. Extremely powerful self-priming capability and lower NPSHr value, and conveying a certain proportion of air-liquid mixed flow is achieved.

6. A variety of bearing cooling modes available, with better protection of bearing and prolonged service life;


Performance  Viscosity:  2.0~100000 mm2/s

Flow:10~1500 m3/min

Maximum Pressure:2.5 Mpa

HW Thus the medium delivery is achieved.This product is with compact structure,stable flow without pulsation,reliable operation,available for high speed,low noise,small vibration,high efficiency,long-service life,strong self-priming ability and so on.


Selection skills

The selection of twin screw pump (high temperature twin screw pump, large flow twin screw pump) includes the selection of performance parameters and pump structure type. The selection of pump structure type refers to the introduction of twin screw pump structure type.


Cavitation margin:

Cavitation allowance of screw pump is related to the speed of pump, the lead and the viscosity of the medium conveyed by the pump. It increases with the increase of axial flow rate and working viscosity. In the case of poor inhalation conditions, it is advisable to select a twin-screw pump with small lead. This is very important in the selection of models.
