Positive Displacement Pump is widely used to transfer various special material, stiff material, mixture with different specific gravity, corrosive material and material with large powder, such as yogurt, cheese, fruit jam, shampoo, cosmetics, syrup, paint etc.
Pump's construction:
1. Driving system
step-less variator +motor. The speed regulator changes the speed by manual adjustment, which is safe, reliable and infinitive flow adjustment. But the non-automatic adjustment is also troublesome. Speed regulating should be done in operation not in shut-off state.
Gear reducer + motor: the driving is easy with constant rotary speed of the rotor,which also leads to nonadjustablity of flow.
Frequency transformed motor + transducer: it realizes both automatic adjusting and infinitive adjustment of flow. It is highly automatic and has large torque in low speed.
2. Connection type: clamp, flange, thread.
3. Contact material: SS304, SS316, 316L.
4. Seal: silicon rubber, fluorine rubber, EPDM, PTFE rubber, nitrile rubber etc.
5. Mechanical seal: single face with silicon carbide/ hard alloy faces standard.
6. We have following types of pump to choose.
