Operation Principle

The suspension is pumped into each sealed chamber of the filter. Under pressure, the filtrate passes through the filter medium, membranes, or other filter materials, and is discharged through the outlet, while the solids remain between the filter plates to form a filter cake, thus achieving solid-liquid separation.

Key Features

Durability

This machine is made of high-quality SUS304 or SUS316L stainless steel, with high strength, corrosion resistance, and durability.

Multi-layer filtration

Multi-layer filtration is adopted. Users can replace different filter media (filter cloth, filter paper, filter membrane, etc.) according to their process requirements (coarse filtration, semi-fine filtration, fine filtration).

No material loss

During operation, the machine has good sealing performance, no material loss, easy operation, and convenient maintenance. The filter plates adopt a flat-thread design, which enhances sealing and reduces filter material loss.

Leak-free

All sealing components are made of silicone rubber or fluororubber, resistant to high temperatures, non-toxic, and leak-free.

Long service life

Equipped with a stainless-steel pump, featuring low noise, large flow, high head, and long service life.

Customizable

Can be designed as mobile or fixed type, with enclosed or open structures, depending on user requirements.

Remarks:

1. For higher flow requirements, customization is available.

2. When using a booster pump, an explosion-proof motor and Grundfos pump are required, with additional cost adjustment. Note: The above images and specifications are for reference only. Please refer to the actual product when ordering.

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.
