The Importance of a Slurry Feed Pump

The Importance of a Slurry Feed Pump

A slurry feed pump is used to supply solids-handling materials to a pump for mixing with liquid or slurry and conveying the mixture through pipe systems.slurry feed pump Unlike clear liquid pumps, slurry pumps must be designed with special materials and features to resist accelerated wear caused by abrasive solids, which are present in many industrial and mining applications. The design of a slurry pump must be carefully engineered, and the impellers are made from hardwearing materials like chrome iron or elastomer to ensure long-term performance.

A high-quality slurry pump is essential for mining, metals and fertilizers industries that require reliable performance when handling abrasive slurries.slurry feed pump The pump uses centrifugal force generated by rotating impeller blades to impact kinetic energy to the medium, resulting in turbulent flow which effectively displaces the solids. Moreover, the pump casing and volutes are designed to optimise slurry flow, leading to low energy consumption and subsequent total cost of ownership.

The key to achieving operational success when pumping slurries is to properly size the suction and discharge pipes.slurry feed pump This includes ensuring the pipe sizes match the Pump’s duty specification, as well as taking into account the maximum head that can be achieved with the pump inlet and discharge pressure. The Pump’s ability to achieve the desired head is dependent on the size of its volutes and shaft, as well as the concentration of the slurry.

Another important consideration is determining the actual head that the Pump must pump against, which is usually different from what is specified in its manual. This is because of system losses, higher concentrations at start-up and other factors that can affect the Pump’s efficiency. It is important to refer back to the Pump’s curve to find the best operating point.

One of the main challenges associated with slurry pumping is that the slurry can clog suction and discharge lines, which causes wear and tear on the Pump and its components. This is often due to incorrect sizing of the pump and its piping. It is therefore vital to consult the Pump’s manufacturer when selecting a Pump for a particular duty.

Whether it’s construction sand, sports sand, specialty sand, tailings, cement, metalliferous mining, sewage or Thickener underflow, McLanahan has a workhorse slurry pump to suit your application. Our pump models are available in a variety of metal compositions, including chrome iron and elastomer-lined constructions, to withstand abrasion from abrasive solids and other contaminants. The pumps are also easy to maintain, as they can be disassembled without the need for a crane or lifting equipment. This makes them an ideal choice for applications where space is limited. The bearing assemblies can also be removed and replaced with ease, allowing you to carry out maintenance quickly and efficiently. This is possible by purchasing a bearing repair kit and following the simple instructions. This will allow you to reduce downtime and increase productivity. McLanahan also offers a range of slurry pump accessories that will help to extend the life of your Pump, including replaceable rubber liners.
