The feed pump for filter presses is equipped with two main impellers installed in opposite directions. During operation, it adjusts to the changing resistance inside the filter press, enabling it to achieve high - flow, low - pressure feeding at the beginning and low - flow, high - pressure filtration later. Its special hydraulic performance precisely matches the gradual process of the filter press, from an empty cavity to being filled and then dried. At the initial feeding stage, there's no need for valve control to limit the flow. This avoids motor overload that could be caused by excessive flow. Meanwhile, the low pressure won't impact the filter plate frames, which reduces the damage to the filter cloth on the frames and prevents the filter plates from vibrating due to the impact. During the later stage of filtration, the low - flow and high - pressure operation is less likely to cause pump blockage. Especially during the high - pressure squeezing stage in the later period, the unique impeller installation method and the function of the auxiliary impeller ensure that there is basically no leakage at the shaft seal.

Product Features of the Feed Pump for Filter Presses

This series of pumps can transport various types of solid - liquid abrasive slurries at temperatures up to 80°C. They can also be used as pressurized feed pumps for various filter presses. For example, they can be used as matching pumps for filter presses or process pumps in the hydrometallurgical processes of non - ferrous metals such as zinc, copper, cobalt, nickel, and manganese. They are also suitable as slurry transfer pumps in mine beneficiation, non - metallic mineral processing (such as titanium dioxide and kaolin), and coal washing plants. In the environmental protection industry, they can serve as pumps for transporting sludge and waste residues. In production processes, they can be used as filter presses or pressure transfer pumps.

Structure of the Feed Pump for Filter Presses

The feed pump for filter presses is a wear - resistant, high - efficiency, and energy - saving slurry pump. It is designed based on the world's advanced design theory, following the principle of minimum loss. This design ensures that the shape of the flow - through components is in an ideal state for the flow of the slurry.

Material of the Feed Pump for Filter Presses

The flow - through components are made of high - hardness wear - resistant cast iron alloy, which has high wear resistance, corrosion resistance, and high - strength impact resistance. This improves the service life of the pump. The design reduces pressure through the power system and has an efficient sealing structure, preventing the slurry from leaking.

Transmission Forms

There are various transmission forms available, including direct connection, belt drive, hydraulic drive, and variable - frequency speed regulation.

Sealing Options

Depending on the requirements of the medium, you can choose from packing seals, single - end face integrated mechanical seals, and double - end face integrated (with a self - contained water tank) mechanical seals.
