▼Product introduction

The filter press pump is a core feed pump specifically designed for filter presses, belonging to either positive displacement or centrifugal pumps. It utilizes corrosion-resistant and wear-resistant materials and special seals, enabling it to stably deliver suspended materials to the filter press under high pressure and low flow rates, overcoming the gradually increasing filtration resistance. It is a key piece of equipment ensuring the efficient solid-liquid separation of the filter press.

▼Application environment

Filter press pumps are specifically designed for use with filter presses and are widely used in industries such as chemical, pharmaceutical, mining, environmental protection (e.g., sludge dewatering), and food processing.

▼Product features and advantages

Corrosion and Wear Resistance: The pumped medium may contain particles.

Special Sealing Design: Employs advanced mechanical seal technology designed to reduce leakage and extend service life.

Adaptable to Filtration Press Conditions: For example, the YL series filter press pumps use a semi-open impeller with a wide flow channel, making them less prone to clogging and suitable for conditions requiring resistance to crystallization and particle control.

▼Working principle

Filter press pumps mostly adopt a centrifugal pump design. Its working principle is that it can automatically achieve dynamic adjustment of parameters according to the characteristic of the filter cake resistance gradually increasing during the filtration process: in the initial stage of filtration, it quickly fills the filter chamber with low pressure and high flow rate; as the resistance increases, it automatically switches to high pressure and low flow rate to continuously squeeze the material until solid-liquid separation is completed.

▼Shopping and maintenance suggestions

When selecting a filter press pump, it is essential to match the filter press model and material characteristics, paying particular attention to its pressure adaptability, corrosion resistance, and wear resistance. Key maintenance points include: regularly inspecting the mechanical seal to prevent dry running, flushing promptly after shutdown to prevent material crystallization and blockage, and lubricating bearings and other components on time to ensure long-term stable operation.

▼Precautions for use

Start-up, shutdown, and pressure control: Before starting, ensure the pump is full of liquid; dry running is strictly prohibited. When feeding, follow the principle of adjusting pressure from low to high to avoid sudden high-pressure impacts that could damage the filter plates and seals.

Sealing and flushing: Regularly check the wear of the mechanical seal and the cooling water system to prevent leaks. For pumps conveying easily crystallizing or granular materials, flush with clean water after shutdown to prevent blockages.

Daily maintenance and materials: Regularly inspect and replace wear parts such as bearings and impellers. Ensure the characteristics of the conveyed medium (such as particle size and viscosity) are within the pump's design limits to guarantee stable operation.
