Causes and Solutions for Weak Plate Pulling in a Filter Press

Fri, 29 May 2026 15:17:49 +0800

During the operation of a Filter Press, weak plate pulling by the plate shifting trolley can affect production efficiency and interrupt normal filtration processes. As a professional filter press manufacturer, Kerte analyzes the common causes of this issue and provides practical solutions to help users maintain stable equipment performance.

1. Increased Friction

Poor lubrication, dust, or debris on trolley rails and wheels can increase friction and reduce pulling force. Regularly clean the rails and moving parts of the filter press, and apply suitable lubricating oil to ensure smooth operation.

2. Insufficient Power

Motor failure, unstable voltage, or worn transmission parts may cause insufficient power in the filter press. Check the motor, drive system, power supply, chains, and gears regularly. Replace damaged components promptly to maintain stable performance.

3. Filter Cloth Problems

Blocked or damaged filter cloths can increase resistance during plate shifting. Clean the filter cloths regularly and replace damaged filter media in time. Proper maintenance improves the working efficiency and service life of the filter press.

4. Trolley Component Failure

Worn bearings, aging chains, or loose parts inside the trolley may also cause weak pulling. Inspect the trolley structure carefully and repair or replace worn components when necessary. Keeping the trolley clean helps the filter press run more reliably.

5. Hydraulic System Failure

Low hydraulic pressure, contaminated oil, or hydraulic pump failure can reduce the pulling force of the filter press trolley. Check the hydraulic oil quality and ensure the pump operates normally. Adjust the hydraulic pressure to the proper range for stable operation.

Regular inspection and maintenance can greatly improve the efficiency and reliability of a filter press system.

Slurry Pump, Screw Pump or Air Diaphragm Pump is the best choice for your filter press?

Fri, 22 May 2026 11:41:39 +0800

Different slurry properties, operating conditions, and industries require completely different pumps. As a professional brand in solid-liquid separation, KERTE Filter Press helps customers accurately match pumps with real operating conditions to improve filtration efficiency.

Among filter press feeding systems, three pumps are most commonly used: air operated diaphragm pumps, screw pumps, and slurry pumps.

Air Operated Diaphragm Pump – Safe and Flexible for Hazardous Fluids

Air diaphragm pumps use compressed air as the power source, eliminating the need for electricity and avoiding spark generation during operation. This makes them ideal for explosive, flammable, and corrosive environments.

These pumps are easy to operate, support dry running, and allow flexible flow adjustment. They are widely used in chemical processing, hazardous waste treatment, coatings, and corrosive liquid transfer applications.

However, diaphragm pumps typically have lower energy efficiency and may generate vibration during operation, often requiring pulsation dampeners for smoother flow.

Screw Pump – Stable Transfer for High-Viscosity Materials

Screw pumps are positive displacement pumps designed for smooth and continuous material transfer. They operate with low noise, minimal vibration, and gentle handling of sensitive materials.

Their biggest advantage is the ability to transport high-viscosity fluids, including paste-like materials, flocculants, paint, sludge, and fluids containing fine fibers or small particles.

Because the rubber stator has temperature and wear limitations, screw pumps are not suitable for highly abrasive slurries or large solid particles. They are commonly used in food processing, pharmaceuticals, and fine chemical industries where stable and low-shear conveying is essential.

Slurry Pump – Heavy-Duty Solution for Abrasive Mining Slurry

Slurry pumps are designed specifically for heavy-duty industrial environments. With large impeller passages and wear-resistant structures, they can continuously transport high-density slurry containing large abrasive particles.

Compared with other pumps, slurry pumps provide higher head pressure and longer conveying distance, making them ideal for mining, coal washing, metallurgy, power plants, and tailings handling systems.

Their disadvantages include more complex structures, higher maintenance frequency, and limited capability for handling highly viscous materials.

At KERTE Filter Press,our engineering team analyzes slurry characteristics, operating conditions, and project requirements to help customers select the most suitable pump and filtration system combination for maximum performance and long-term reliability.

Filter Press or Horizontal Centrifuge? Discover the Better Dewatering Solution

Fri, 15 May 2026 15:19:50 +0800

Choosing the right equipment for solid-liquid separation directly affects operating cost, energy consumption, and final product quality. At Kerte Filter Press, we often help customers compare a filter press with a horizontal centrifuge to find the best solution for mining, chemical, and wastewater treatment applications.

1. Working Principle

A filter press separates solids and liquids through pressure filtration. Slurry is pumped into the chambers, liquid passes through the filter cloth, and solids remain to form a dry filter cake. This process allows the filter press to achieve excellent separation performance, especially for fine particles and high-solid slurries.

A horizontal centrifuge uses high-speed centrifugal force to separate materials. The rotating drum continuously removes solids and liquid during operation. While this method supports continuous processing, separation efficiency may decrease when handling ultra-fine particles or sticky sludge.

2. Cake Moisture and Separation Efficiency

One major advantage of the filter press is lower cake moisture. After dewatering with a horizontal centrifuge, the cake moisture content is typically around 70–85%. In comparison, a filter press can reduce cake moisture to as low as 10%, depending on the material and process conditions.

Because of this performance, a filter press is widely used in mining tailings, chemical slurry, and industrial sludge treatment where dry solids and maximum water recovery are required. The filter press also produces cleaner filtrate, helping plants improve recycling efficiency and reduce disposal costs.

3. Energy Consumption

Energy consumption is another important factor. A horizontal centrifuge relies on high-speed rotation, which usually results in higher power consumption and increased maintenance requirements.

By comparison, a filter press operates with pressure filtration and generally consumes less energy during long-term operation. For many plants, using a filter press helps reduce operating costs while maintaining stable dewatering performance.

4. Application and Capacity

A horizontal centrifuge performs well in continuous large-flow operations with limited installation space. A filter press operates in batches, but it offers stronger adaptability for fine particles, tailings, sludge, and high-concentration slurry treatment.

At Kerte Filter Press, we provide customized filter press solutions designed for efficient dewatering, lower moisture content, and reliable long-term operation across demanding industries.

Recessed vs Membrane Filter Plates: A Guide for Efficient Industrial Filtration

Fri, 16 Jan 2026 16:20:02 +0800

A filter press relies on high-quality filter plates to efficiently separate solids from liquids. These plates form chambers where slurry is captured, producing clarified filtrate and a manageable filter cake. Selecting the right filter plate is crucial for optimal performance, cake dryness, and overall process efficiency. At Kerte, we provide reliable filter plates designed for diverse industrial applications.

Two common types of filter plates are recessed filter plates and membrane filter plates. While both serve the primary purpose of solid-liquid separation, their design and performance characteristics differ, influencing efficiency and output.

Recessed filter plates have a rigid, recessed surface that holds the filter cloth in place. Slurry enters the chamber created by the filter plate, and solids form a cake. Recessed plates are known for their durability and simplicity. They are ideal for processes where moderate cake dryness is sufficient and mechanical compression is not needed. Industries such as chemical manufacturing, mining, and wastewater treatment frequently use recessed filter plates in filter press systems for reliable operation and minimal maintenance.

Membrane filter plates, on the other hand, include a flexible membrane over the filter plate surface. After initial filtration in the filter press, the membrane inflates using air or water to compress the filter cake, significantly reducing moisture content. Membrane plates provide superior dewatering, faster cycle times, and higher cake dryness, which is essential in food processing, pharmaceuticals, and chemical industries. Proper handling and periodic inspection ensure membrane filter plates maintain peak performance.

Choosing the right filter plate for your filter press depends on your process needs. Recessed filter plates offer durability and simplicity, while membrane filter plates deliver advanced dewatering and efficiency for demanding applications. At Kerte, we provide both options, helping industrial operators optimize filtration, improve productivity, and achieve consistent results.
