1. The motor can not overload from the initial high-flow feeding to the long-term high-pressure pressing in the later stage of pressing.
2. The performance curve is steep. With the change of feeding resistance, the automatic conversion of high flow low pressure and low flow high pressure can be realized.
3. Keep high pressure leak-free all the time
The feed pump of filter press is a kind of filter press pump with special performance. It sucks slurry from the back side. Simple packing and impeller seal can stop the pump without leakage. More importantly, its flow rate and head curve are very steep. It is very suitable for the feed performance of plate and frame filter press. This series of special pump for filter press has passed provincial appraisal and obtained national patent. It is called "special feeding pressure pump for plate and frame filter press" by people in the industry.
