ZJE Frame Filter Press Feed Pump
ZJE Frame Filter Press Feed Pump is a specialized pump designed to efficiently supply feed material to a plate and frame filter press system. ZJE specializedfilter press feed pump pump is a type of slurry pump with special performance. In recent years, it has been referred to as the "special feed pump for filter presses" by industry insiders. The pump sucks in the slurry from the rear side, with a simple packing seal without leakage. More importantly, its flow and head curves are very steep, making it very suitable for some special working conditions.

Principle of ZJE Frame Filter Press Feed Pump
1. Feed stage: At the beginning of feeding, the filter chamber of the filter press is empty and needs to be quickly filled with materials. The ZJE filter press feed pump initially uses high flow rate feeding to ensure fast filling of the filter press.
2. Boosting filtration stage: When the pressure inside the filter press is filled with materials and begins to rise, the filter press quickly releases water. At this time, the filter press still needs to feed with a large flow rate. During the low-pressure period of the ZJE filter press pump, it can still ensure fast and efficient filtration of high flow feed. As the feed pressure gradually increases, the filter cake inside the high-pressure filter begins to thicken, the water output of the filter press begins to decrease, the filtration capacity of the filter press also decreases, and the feed rate also decreases.
3. Pressure maintaining filtration stage: When the filtration pressure of the filter press reaches the maximum set pressure, it is necessary to maintain a constant feed pressure for filtration. The filtration capacity of the filter press further decreases until the filtration is completed. At this point, the flow rate of the dedicated ZJE filter press feed pump for the filter press decreases to the minimum and begins to maintain constant pressure feeding.
In summary, the working status and characteristics of the ZJE filter press feed pump are as follows: the filter press pump maintains a high flow rate when feeding the filter press and during low-pressure filtration. As the filter press chamber is filled with material, the pressure also increases. At this time, the filtration capacity of the filter press begins to decrease. When the set pressure value is almost reached, the output flow rate of the ZJE filter press feed pump decreases until it is filled with material, Then continue working to maintain a constant pressure to ensure that the moisture in the slurry is quickly squeezed out, and then complete the filtration work. ZJE filter press feed pump can gradually decrease with the filtration capacity of the filter press, and the feeding pressure gradually increases. The feeding flow rate of the pump automatically decreases, with a minimum flow rate of 20% of the rated flow rate. The pump output flow pressure curve is basically consistent with the optimal filtration curve of the filter press, so it is necessary to choose a special pump for feeding the filter press.
Features of ZJE Fame Filter Press Feed Pump:
There is no need for frequency conversion for feeding materials into the filter press, and the conveying concentration is high.
Hydraulic design, novel structure design, high efficiency, corrosion resistance, stable and reliable operation; The flow components of this pump are all made of high chromium alloy materials such as Cr27 and Cr30, which gives it superior wear resistance when conveying various types of slurry.
In the early stage, the feeding flow rate is large and the pressure is low; In the later stage of pressing, the flow rate is small and the pressure is high.
Double impeller pumps have better wear resistance than single impeller pumps. Due to the fact that the double bladed impeller pump obtains higher pump outlet pressure at a lower impeller outlet line speed, it overcomes the characteristic of increasing impeller outlet line speed to increase pressure by a single bladed impeller, which leads to increased wear of the impeller and pump casing, effectively improving the service life of the pump's flow components.
The shaft seal is simple and reliable, no water injection, no mechanical seal, no leakage; Adopting lip type rubber seal and high-quality carbon fiber packing, coupled with wear-resistant shaft sleeve made of high chromium material, ensures long-term operation of the pump without leakage.
The non-leakage filter press pump is more convenient to operate, easy to maintain, and has a long service life. The parts made of high-quality materials are also not easy to damage.
Wide application range. On the basis of the original 1450r/min, our company has added a new low speed 970r/min pump, making it more durable and stable in the transportation of various heavy metals such as metal concentrates, tailings, and calcium carbide compared to other 1450r/min single blade wheel slurry pumps.
