Filter press feeding pump

The feed pump of the filter press is widely used, especially in industries such as metallurgy, mining, power plants, and chemical engineering. It has been found that this series of products has the characteristics of reasonable structure, reliable operation, and long service life. This series of products adopts a unique hydraulic design and a dual stage impeller structure, ensuring that its performance curve is steeper than that of the filter press feed pump modified from ordinary centrifugal pumps such as YLB, UHB, HFTK, etc., making it more suitable for the special operating conditions of filter press feeding.

Product features of filter press feeding pump:

1: This series of pumps can transport various types of solid-liquid abrasive slurries with a temperature below 80 ℃ or be used as pressure feeding pumps for various filter presses, such as filter press pumps or process pumps for wet smelting processes of non-ferrous metals such as zinc, copper, cobalt, nickel, manganese, slurry conveying pumps in mining beneficiation and non-metallic mineral processing (titanium dioxide, kaolin, etc.) coal washing plant processes, sludge and waste residue conveying pumps in environmental protection industries, filter press pumps or pressure conveying pumps in production processes.

2: Structure of filter press feed pump: Adopting advanced international design theory and designed according to the principle of minimum loss, the shape of the flow components and the flow state of the slurry have reached the ideal state.

3: Material of filter press feed pump: The overcurrent components are made of high hardness and wear-resistant cast iron alloy, which has high wear resistance, corrosion resistance, and high-strength impact resistance, improving the service life. Power pressure reduction, efficient sealing, and less leakage of slurry.

4: Transmission form: It has transmission modes such as direct connection, belt, hydraulic, and variable frequency speed regulation.

The feed pump of the filter press utilizes advanced fluid theory and adopts dual main impellers installed forward and backward. During operation, it cooperates with the resistance changes inside the filter press to achieve the purpose of high flow, low-pressure feeding and low flow, high-pressure filtration. Its special hydraulic performance perfectly matches the gradual natural feature of the filter press from cavity to filling and then to drying. During the initial feeding stage, there is no need to control the motor overload caused by excessive flow through valves. At the same time, low pressure will not have an impact on the filter plate frame, reducing the impact on the filter cloth frame on the filter plate frame and reducing the damage to the filter cloth on the filter plate frame. It will also not impact the filter plate and cause the core to stir. The small flow rate in the later stage of pressure filtration is less likely to cause pump blockage and filter press inlet blockage.
