What is a Submersible Slurry Pump?

Submersible Slurry pumps are heavy-duty pumps specifically designed to handle slurry and other fluids that are a mixture of solids and liquids. Slurry pumps are typically larger than most pumps and have a much higher horsepower rating. Available as a Centrifugal Slurry Pump or Positive Displacement Configurations.

Slurry Pumps can handle abrasion, erosion, corrosion, wear and tear, and heavy pumping work overall. Submersible pumps are commonly used in applications like food and beverage, mining, construction, biopharmaceutical manufacturing, and cosmetics.

Common characteristics of slurries include:

  • Abrasive nature
  • Thick consistency
  • High solid content
  • Rapid settling
  • Greater power requirement than a standard “water” pump

Essential Components of a Slurry Pump

A slurry pump is a specialised piece of machinery designed to transport and process significant amounts of liquids, solids, and other materials. Its construction involves several essential components:

Volute or casing

This component, resembling a curved funnel, collects and channels the flow of the material being pumped. Its construction typically involves chrome alloy steel, a durable material that can endure the slurry’s high pressures and abrasive nature.


This rotating part propels the liquid forward and out of the volute. Depending on the specific requirements of the pump, this component can be made from sturdy materials like chrome alloy steel or softer substances like flexible rubber.


This is a metal rod that serves as the connection between the impeller and the motor or engine. It’s constructed from high-strength materials such as stainless steel. In some designs, a shaft-mounted agitator is included for improved performance.

Sealing mechanism

This part consists of a series of mechanical or hydraulic seals designed to prevent leakage of the pumped material around the impeller. It moves flexibly with the flow of the material.

Motor or engine

This is the power source of the slurry pump. It could either be a traditional electric motor or an internal combustion engine, depending on the design.

Base plate

This is the support structure of the slurry pump. It accommodates the motor or engine and the bearing assembly, ensuring stability during operation.

How Does a Slurry Pump Work?

A slurry pump, which is a type of centrifugal pump, works by using kinetic energy to move a mixture of liquid and solid particles. In its most basic form, the pump includes an inlet where the slurry enters, and it’s then exposed to the centrifugal force generated by a rotating impeller.

This force moves the slurry from the centre of the pump outwards, which creates a void for more slurry to enter the pump at the inlet. This movement of the slurry also generates pressure.

Each stage of the pump increases the pressure further, resulting in a highly pressurised output. Centrifugal slurry pumps are specifically designed to handle abrasive and often corrosive slurry mixtures, making them ideal for industries such as mining and construction.

Their efficient pumping action and ability to handle solid particles make them a reliable choice for these demanding applications.

Applications for Slurry Pumps

Because of their unique ability to move fluids containing solid particles, slurry pumps are essential to many different industries.

In sectors such as mining, metallurgy, coal washing, power plants, sewage water treatment, dredging, and chemical and petroleum industries, slurry pumps are vital. They help in transporting abrasive solids suspended in fluids, commonly known as slurries.

The food, dairy, beverage processing, and biopharmaceutical manufacturing industries also rely on slurry pumps. They handle food-grade products like mashes and food slurries that typically contain small suspended solids.

Slurry pumps are also crucial for domestic purposes, including pumping water for daily requirements, distributing water to different areas, circulating hot water, managing boiler water, draining sewage, and supporting fire protection systems. They work to enhance pressure, ensure efficient water movement, and prevent blockages.

Hunter Pumps provides these essential slurry pump solutions, catering to both industrial and domestic needs.
