Filter press feeding pumps
Filter press feeding pumps
The filter press feed pump uses a semi-open impeller, the flow channel is wide, the passage is good, there is no blockage when conveying the slurry containing particles, and the particles will not get stuck between the impeller and the pump body and the pump cover, so as to make up for the effect that the general centrifugal pump can not achieve. Filter press feed pump structure is simple, easy to maintain, unique structural design, in the maintenance and replacement of impeller, seal, bearing and other wearing parts, without disassembling the pipe can be completed.
Filter press feed pump adopts a unique hydraulic design and impeller installation mode to ensure that its performance curve is steeper than the general impurity pump, which is very suitable for the change of resistance when the filter press feed to achieve the purpose of large flow, low pressure feeding and small flow, high pressure filtration. Its special hydraulic performance coincides with the progressive process of the filter press from cavity to filling and then to filtration. At the beginning of feeding, the motor overload caused by excessive flow control without valve will not have an impact on the filter plate frame at the same time, which reduces the damage of the filter cloth on the filter plate frame, and will not impact the filter plate causing vibration, and the small flow and large pressure in the later stage of filter press is not easy to produce a suppressed pump. Especially in the late pressing period, with the pump under large pressure, its unique impeller installation mode and the role of the auxiliary impeller to ensure that the shaft seal basically achieves no leakage.
HDZ type filter press feed pump is a kind of special properties of impurity pump. The pump is composed of the side after inhalation of slurry, the flow, lift curve suitable for some special conditions.
HDZ type filter press special feeding pump features:
1. Advanced Hydraulic and structure design, high efficiency, abrasion, stable and reliable operation;
2. High feed flow and low pressure;
3. Low flow and high pressure discharge;
4. Simple shaft seal is reliable, no water, no mechanical seal, no leakage;
5. Filter feeding no need frequency conversion adjusting speed, high concentration conveying.
HDZ filter press feeding pump is suggest that feeding level higher than the center height of the pump. The pump inlet pipe should not be too long.
