Heavy-duty Non-lined Metal Pump

The Multotec non-lined metal pump, also known as the heavy-duty gravel pump, has been designed with increased wear resistance and to efficiently transport highly dense and abrasive slurries.

Ideal for a wide range of applications, this slurry pump is designed to provide simplified maintenance and lower overall ownership costs. This is thanks to a specially designed clamp that provides easy strip down and reassemble.

Manufactured in South Africa to withstand tough operating conditions, this metal pump is constructed with a combination of alloys to provide long-lasting performance. This horizontal, non-lined metal pump range features a 3-vane impeller design to accommodate large particle sizes with high processing efficiency.

The pump discharge sizes vary from 100 to 250 mm.

Features of this pump:

  • Unlined volute design
  • Interchangeable medium- and heavy-duty bearing units
  • Simplified single-piece frame design
  • Designed to support standard- and heavy-duty bearing units
  • Minimised vibration and shaft deflection

Multotec’s expertise in Pumps:

In 2015, Multotec expanded its product range to include solutions for mining and mine processing applications. We now offer a comprehensive range of pumps for ferrous and non-ferrous recovery processes.

We have developed eight ranges of industrial slurry pumps for mineral processing, building sand and gravel.. These are designed to cut costs and increase overall process efficiency.

Our pump range incorporates solutions for abrasive slurry operations, medium-duty slurry applications, CIP processes, large solids, abrasive slurries and sump applications that include spillage and carbon transfer. Some units feature interchangeable casing liners and are available in different spindle lengths and various construction materials.


Multotec products are engineered to optimise costs, lifespan and efficiency of mineral beneficiation plants.
