Product Introduction

The HFM series is a new type of lined, back-suction filter press pump (with the shaft seal positioned in the same direction as the liquid inlet), corrosion-resistant, and wear-resistant. This filter press feed pump was developed to address the issues with conventional corrosion-resistant and wear-resistant pumps, which can easily cause seal leakage during operation. It utilizes five innovative technologies.

This series of filter press pumps can transport various corrosive and non-corrosive liquids and slurries at temperatures up to 100°C, and can also be used as a pressure feed pump for various filter presses.
Applications requiring long-term high-pressure operation (high pump outlet pressure) to transport corrosive media, such as pressure spray pumps and pressure flushing pumps used in flue gas desulfurization and atmospheric treatment.
Applications where other pumps are prone to leakage when transporting media.
This filter press pump series is available in single-stage and two-stage series, meeting requirements for low-flow, high-pressure transport of corrosive slurries.

Key Features and Advantages

Advantages

Adaptable to chemical process requirements, it offers corrosion resistance, high and low temperature resistance, wear resistance, and erosion resistance, ensuring reliable operation and capable of conveying critical liquids.

Applications

Filter presses and process pumps for hydrometallurgical smelting of non-ferrous metals such as zinc, copper, cobalt, nickel, and manganese; slurry transfer pumps in mineral processing, non-metallic mineral processing, and kaolin; sludge and waste transfer pumps in the environmental protection industry; and filter presses and pressure transfer pumps in other chemical, dye, pharmaceutical, and food production processes.

Not suitable for applications where the liquid level in the inlet wave is less than 1.2m below the pump level or where the negative pressure at the inlet is excessive.

Frequently Asked Questions

Our popular products include: vehicle-mounted sludge solidification units, diaphragm filter presses, sludge dewatering machines, as well as engineering design and installation services for municipal sludge and sand-washing sludge treatment.

How to choose the right filter press model based on material properties?

Selecting a filter press model depends on key material properties: particle size (to determine filter cloth mesh), viscosity (affects required pressure), corrosiveness (dictates filter plate material, e.g., PP for mild corrosion, stainless steel for strong), and solid content (influences filtration area and cycle time). High-solids materials need larger filtration areas, while abrasive materials require wear-resistant plates. Match pressure ratings to material viscosity—thicker slurries need higher pressure (1.0–2.5 MPa) for effective dewatering.

What to do if filter plates leak?

First, stop operation and check:

Filter cloths: Replace damaged or misaligned cloths that disrupt sealing.
Filter plate seals: Inspect for cracks, wear, or debris; clean seals or replace plates if damaged.
Pressure imbalance: Ensure uniform pressure across plates (adjust hydraulic system if uneven).
Plate alignment: Realign plates if shifted during operation. Test with low pressure after fixes to confirm leaks are resolved.

Do filter cloths need regular replacement? How often?

Yes, filter cloths require regular replacement as they clog, tear, or degrade over time, reducing filtration efficiency. Frequency depends on material: 4–8 weeks for abrasive/viscous materials (e.g., mining slurries); 3–6 months for less harsh materials (e.g., food-grade liquids). Signs to replace early: slower filtration, increased pressure, or visible damage (holes, fraying).

Is installation and operation training provided after purchase?

We offer installation and operation training post-purchase. This typically includes on-site installation guidance, hands-on operation training (e.g., setting parameters, troubleshooting), and documentation (manuals, video tutorials). Some provide follow-up support for 1–3 months to ensure operators master key functions, especially for automated or custom models.

If the power supply is not the issue, how to fix the machine tripping and shutting down?

Check these common causes:

Overload: Motor may be overworked (e.g., excessive slurry feed); reduce load or inspect for jammed components (e.g., filter plate movement).
Faulty sensors: Pressure or temperature sensors may trigger safety shutdowns; calibrate or replace malfunctioning sensors.
Hydraulic system issues: Low oil level or clogged filters can cause pressure spikes; check fluid levels and clean/replace filters.
Electrical connections: Loose wires in control panels may interrupt power; tighten connections and inspect for short circuits.
