Introduction

The ZJE series filter press feed pump is a specially designed slurry pump developed based on fluid dynamics principles. It utilizes a dual impeller design with opposite rotation, and a compact mechanical seal to prevent leakage. During operation, the pump utilizes the pressure changes within the filter press to achieve high initial flow rate and low pressure, reducing impact on the filter plate frame and extending filter cloth lifespan. The low flow rate in later stages prevents pump stalling and filter press clogging, reducing energy consumption and eliminating the need for speed control during filter press operation.

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.
