Special feed pump for filter press

Filter press special feeding pump is a pump equipment designed for filter press feeding. It is widely used in many industries such as petroleum, chemical, starch, pharmaceutical, pesticide, dye, paint, leather, paper, food and so on. The pump has a variety of features and advantages that make it an ideal choice for filter press feeding process.

First of all, the special feeding pump for filter press has the characteristics of simple structure and easy maintenance. Its unique structural design makes it possible to complete the maintenance and replacement of impellers, seals, bearings and other wear parts without dismantling the pipeline, which greatly improves the maintenance efficiency.

Secondly, the pump adopts unique hydraulic design and impeller installation method. This makes its performance curve steeper than that of general impurity pumps, which is very suitable for the purpose of realizing high-flow, low-pressure feeding with low-flow, high-pressure filtration in response to the change of resistance when the filter press is fed. Its special hydraulic performance coincides with the gradual process of filter press from empty chamber to full and then to filter dry.

In addition, the special feeding pump for filter press also has excellent sealing performance. In the case of increasing pressure and decreasing flow rate, the sealing components do not bear pressure, especially in the later stage of filtration, when the pump is in high pressure, its sealing structure design ensures that the shaft seal basically realizes no leakage, effectively preventing material leakage and environmental pollution.

At the same time, the pump adopts the structure design of two-stage impeller. This design not only solves the problems of excessive vibration and noise, flat performance curve, narrow impeller channel and poor passing performance of single impeller pump, but also makes the pump have better wear resistance. As the double impeller pump to lower impeller outlet linear velocity to obtain a higher pump outlet pressure, to overcome the single impeller pump to increase the impeller linear velocity to increase the pressure caused by the wear and tear of the problem of increasing, thus effectively extending the service life of the pump and other overflow components.

In addition, the clearance between the impeller and the pump wall of the filter press special feeding pump is adjustable. This design makes it possible for users to continue to ensure the high pressure of the pump by adjusting the gap between the impeller and the pump wall when the pressure drops due to wear and tear after a long period of use, which further improves the service life of the pump and shortens the maintenance cycle of the pump.

In summary, the special feeding pump for filter press plays an important role in the feeding process of filter press with its unique structural design, superior hydraulic performance, good sealing performance and wear resistance, and adjustable impeller clearance. Whether it is high flow and low pressure feeding in the early stage or low flow and high pressure filtration in the later stage, the pump can meet the demand and provide a strong guarantee for the normal operation of the filter press.
