Engineering Reliability for Heavy Industry

Why EPC contractors and plant managers rely on our filtration systems for critical process bottlenecks.

Precision Manufacturing

Equipment consistency is key for scaling LFP production. Our 90,000㎡ facility uses CNC machining for filter plate molds, ensuring ±0.1mm tolerance and zero leakage at 1.6MPa, reducing downtime.

Complete System Integration

Sourcing separate components causes compatibility issues. We provide complete structures, custom cloths, and matching plates for seamless integration.

Custom Slurry Engineering

Standard presses struggle with abrasive mining slurries. We customize feed ports and automate cake discharge to cut manual labor and cycle times by 30%.

Global Technical Support

Commissioning hydraulic systems overseas demands on-site expertise. We offer mounting hole layouts, Siemens PLC schematics, and dispatch engineers to ensure timely plant operation.

Industrial Filtration Equipment

Manufactured to CE standards. From individual filter plates to fully automated dewatering lines with MOQ 1 set.

Filtration Technical Resources

Engineering insights on filter press selection, installation, and maintenance.

Chamber vs. Membrane Filter Press: Which should I choose?

A chamber filter press relies solely on the feed pump pressure (typically 0.6-0.8MPa) to dewater the slurry. It's cost-effective for standard municipal sludge. A membrane filter press includes flexible plates that inflate with compressed air or water (up to 1.6MPa) to physically squeeze the filter cake after the feed cycle. This secondary squeeze significantly lowers final cake moisture, making it ideal for LFP battery materials or kaolin where thermal drying costs must be minimized.

How do I select the correct filter cloth for my application?

Filter cloth selection dictates filtrate clarity and cake discharge efficiency. We evaluate three factors: 1) Material (PP for general use, PET for high temp, Nylon for abrasion). 2) Weave type (plain weave for high retention, twill for better cake release). 3) Air permeability. We require a 5L slurry sample to conduct laboratory filtration tests before recommending the specific micron rating and mounting hole configuration for your plates.

What are the installation requirements for the electrical control cabinet?

Our standard control cabinets are IP55 rated. We provide detailed cabinet drawings, including mounting holes and cable entry points, 3 weeks prior to equipment delivery. The cabinet requires a standard 3-phase power supply (voltage customized to your country, e.g., 380V/50Hz or 480V/60Hz). The PLC (Siemens/Allen-Bradley) comes pre-programmed, but requires hardwiring to the hydraulic station, feed pump, and limit switches on site based on our provided schematics.
