Transferring Thickener Subslurry with Verderflex

"Intense, abrasive, challenging..."
One solution for all: Verderflex

Sector: Mining & Metallurgy

Application: Concentrator for Sludge Transport

Application Detail: Thickener Sludge Transfer Pump

Situation

A mining facility faced significant challenges in transporting highly abrasive thickening downstream mud. The application involved three types of mud with varying levels of abrasiveness:

High-grade nickel concentrate (very corrosive)
Copper and nickel mixed mud
Copper slurry with low nickel content

Main operational parameters:

  • Flow rate up to 22 m³/h
  • Up to 72% solids content
  • The solid density varies between 4.29 and 4.97.

Existing rubber-coated centrifugal pumps were constantly failing due to the abrasive nature of the sludge, requiring frequent maintenance, and reducing the plant's efficiency.

Solution

To solve these problems, the mining facility installed three Verderflex VF 80 Series hose pumps, which offer superior durability and long service life in corrosive environments.

  • Expansion joints and flexible suction hoses were integrated to minimize impact losses.
  • An 80-liter pulsation damper and flexible hose were fitted to the outlet of each pump to reduce vibrations and improve system performance.
  • The hoses have a service life exceeding 4000 hours, providing superior durability under harsh conditions.
  • In addition, three extra backup units are commissioned as part of an independent concentrate pumping station, guaranteeing continuous and reliable operation.

Benefits

  • SRL reduced maintenance costs by eliminating frequent failures in centrifugal pumps.
  • By providing a service life of over 4000 hours, it significantly extended maintenance intervals.
  • It increased the plant's efficiency by preventing more than 100 hours of downtime annually.
  • It optimized system stability by reducing vibrations and fluctuations.
  • It exceeded operational targets and achieved 100% flow reliability.

As of today, Verderflex VF 80 Series hose pumps continue to demonstrate exceptional performance in handling highly abrasive thickened downstream sludge, proving to be a superior alternative to conventional centrifugal pump systems.
