Filter Press Feed Pump’s Operating Principle

Plate and frame filter presses are becoming more and more common place in fines recovery applications at coal preparation and mining operations around the world with the steady elimination of settling or tailing ponds. These presses carry a relatively high capital cost, but the payoff is in the long-term savings on chemicals and pond management. The dried cake that the presses produce is ideal for transportation off-site, and many end-users have found that this by-product can be sold for a variety of alternative uses. The heart of these filter presses is the centrifugal pump that fills the press, and subsequently aids in the hydraulic pressing of the material. GS Slurry pump has developed a specific line of pumps and impellers which are tailored for these heavy duties.

The slurry that is pumped into the press is generally laden with 30-40% solids by weight. The solids are ultra-fine in nature, and can cause significant, sometimes catastrophic, wear and tear on the standard pumps offered by many of the filter press manufacturers. GS Pump takes a different approach to this problem by putting in place the most robust slurry pump that we manufacture, with incredibly low specific speed impellers to reduce wear, heat buildup and many other contributing factors that cause other pumps to fail prematurely.

These GS Pump HH Series high-head, severe-duty slurry pumps have been fitted with specialized impellers to provide hydraulic characteristics tailored to filter press feed applications. While other pumps suffer regular seal, bearing and wear part failures, the GS Slurry pump triumphs!
