The plate and frame filter press pump is a solid-liquid conveying device specially designed for plate and frame filter presses. It is mainly used to pressurize and convey materials such as slurries and suspensions to the filter chambers of the plate and frame filter press. Solid-liquid separation is achieved through the extrusion between filter plates and filter frames. Its performance directly affects the working efficiency of the filter press, the quality of the filter cake, and the stability of the system.

2. Core Functions

High-pressure and Stable Conveyance

• It provides a continuous and stable pressure to meet the high-pressure requirements during the feeding stage of the filter press, ensuring that the materials are evenly filled into the filter chambers and efficiently dewatered.

• It can automatically switch between high-flow and low-pressure feeding and low-flow and high-pressure filtration according to the resistance changes during the filtration process, matching the entire process of the filter press from feeding to pressing.

Handling of High-solid-content Materials

• For high-concentration slurries in industries such as mining and chemical engineering (e.g., tailings slurry, mine sludge, dye slurries), it adopts large-channel impellers, wear-resistant materials, and special hydraulic designs to prevent blockages and ensure conveyance efficiency.

Leak-free Sealing Design

• Through negative-pressure sealing, double mechanical sealing, or magnetic sealing technology, it solves the leakage problem under high pressure and highly corrosive media, improving the system's safety.

3. Technical Features

Structural Optimization

• It uses a double-impeller structure or a low-speed and large-flow-channel design to reduce wear and improve the passageability of materials containing particles.

• The reverse installation of the impeller or a special axial inlet design reduces the retention of materials in the pump chamber, avoiding blockages.

Material Diversity

• The flow-through components (impellers, pump bodies) can be made of materials such as carbon steel, stainless steel, fiberglass, rubber lining, and fluoroplastic alloy to meet the corrosion and wear resistance requirements of different media (e.g., acid and alkali solutions, slurries).

Intelligence and Energy-saving

• Some models are equipped with a variable-frequency control system, which can automatically adjust the flow rate and pressure according to the operating conditions of the filter press, reducing energy consumption.

• It has a steep performance curve, which can adapt to the resistance changes during the filtration process and avoid motor overload.

4. Application Fields

• Mining Beneficiation: Conveying tailings slurry and concentrate slurry to the filter press for dewatering.

• Chemical Industry: Handling high-solid-content slurries such as dyes, pigments, and catalysts.

• Environmental Protection: Conveying sludge and waste residues for volume reduction treatment.

• Metallurgy and Electroplating: Handling solid-liquid separation of metal processing wastewater and electroplating waste liquid.

• Other Industries: Processes requiring solid-liquid separation in industries such as petroleum, starch, pharmaceuticals, and papermaking.
