Orion Series Slurry Pumps

The Orion range of horizontal slurry pumps are rugged pumping equipment designed for abrasive slurries. The series consists of two series: the heavy-duty H-series and the mining-type M-series. In both series, the pumps are available in rubber-lined or hard-metal-lined versions.

Low total cost

This is the result of more than 60 years of experience in thousands of pumping applications.

Low power consumption

Optimal power utilization. Operate close to the optimum efficiency point. Improve hydraulic efficiency.

Long wear life

Wear parts are made of the highest quality hard metal, rubber and corrosion-resistant materials. Extra-thick sections at known wear points.

Operational reliability

Pumps and parts are manufactured in ISO-certified production units under Total Quality Management.

Orion series, H-series, and M-series

Product Availability

H range

Designed for the toughest industrial slurry pumping applications. Consists of a hard metal lined (HM) and rubber-lined (HR) pump.

Flow rates up to 2 800 m3/h – 10 000 USGPM
Lifts up to 100 m – 330 ft

M series

Designed for abrasive tasks and medium-sized heads in general equipment handling applications. Covers both hard metal lined (MM) and rubber-lined (MR) pumps.

Flow rates up to 5 000 m3/h – 20 000 USGPM
Heads up to 60 m – 200 ft

To make the Orion range of slurry pumps easily fit into any of your processing plant applications, these pumps can be equipped with a variety of motor arrangements, such as:

Direct coupling
Overheaded
Side-mounted
Reverse overhead

New for 2024

  Options
  
  Impeller options
  
  Standard closed impeller
  
  Induced flow (vortex) impeller
  
  Fully concave induced flow (vortex) impeller
  
  Shaft sealing options
  
  The whole process
  
  When product dilution is not critical, it is used for suction conditions that are not suitable for centrifugal sealing. Full flow provides the longest packing wear life.
  
  Low flow
  
  When product dilution needs to be minimized, it is used for suction conditions that are not suitable for centrifugal sealing.
  
  Standard secondary impeller shaft seals
  
  For product-free dilution against positive tips without leakage.
  
  Metso slurry mechanical seals
  
  For stuffing boxes with zero leakage or product dilution. Single-slurry mechanical seals are available or dual mechanical seals requiring an external isolation fluid.
  
  Special configurations
  
  The Orion range of slurry pumps is also available in a variety of special configurations:
  
  HP – High Pressure:Same as HM with a higher pressure heavy-duty housing.
  
  HG – Heavy Gravel:Same size suction and discharge flanges, fewer impeller blades, and larger material sizes can be passed.
  
  HT – Heavy Tunnelling:Same as HM with a special 90° elbow cast into the casing.
  
  HH – High Head:For a given flange size, the impeller diameter is larger.
