How to choose the feed pump of the plate and frame filter press

    If you want to choose the feed pump for the plate and frame filter press reasonably, you must fully understand its working characteristics. With the gradual formation of filter cake in the filter chamber of the plate and frame filter press, the feeding resistance also increases. It is required that the feed pump of the filter press is reflected in the curve from the large flow and low head at the beginning to the small flow and high head at the end. The listing needs to have a longer or even a more complete flow and head curve that is as steep as possible.

The feed pump of the filter press is mainly selected according to the material properties, solid content, particle size PH value, viscosity, temperature and other parameters. Its characteristics are mainly as follows:
　　 1. Hydraulic design, novel structure design, high efficiency, anti-abrasion, stable and reliable operation.
　　2. The pre-feeding flow is large and the pressure is low.
　　3. The later pressing flow is small and the pressure is high.
　　4. Simple structure, convenient disassembly and assembly, no need to disassemble the feed pipe during maintenance.
　　5. The shaft seal is simple without water injection, no mechanical seal, and no leakage.
　　6. ​​The filter press feed does not need frequency conversion speed regulation, and the conveying concentration is high.
The main differences between it and ordinary pumps are:
　　 1. From the large flow in the early stage of feeding to the long-term high pressure in the later stage of pressing, the motor cannot be overloaded.

　　2. The performance curve is steep. With the change of the feed resistance, the automatic conversion between large flow and low pressure and small flow and high pressure can be realized.
Doyen filter press manufacturers suggest that you must understand the basic performance of the filter press and the feed pump when purchasing, or you can ask professional personnel to make recommendations, and do not affect the equipment itself because of inappropriate equipment selection The good performance.
