Orion Series horizontal slurry pumps.

Orion Series horizontal slurry pumps

Rubber and hard metal lined pumps for abrasive applications

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

Low total cost

The result of over 60 years of experience from thousands of pumping applications.

Low power consumption

Optimal power utilization. Operate close to the best efficiency point. Improved hydraulic efficiency.

Long wear life

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

Reliability in operation

Pumps and parts are manufactured under total quality management in ISO certified production units.

  • Sand and gravel
Low total cost

The focused product development combined with over 60 years of experience from thousands of pumping applications has led to continuous improvements in Orion Series slurry pumps.

These slurry pumps offer numerous benefits to customers but the most significant are the lifetime cost savings that can be achieved.

To make Orion Series slurry pumps easily fit to your application in any processing plant, the pumps are available with various motor arrangements such as:

  • Direct coupled
  • Overhead mounted
  • Side mounted
  • Reverse overhead mounted

Orion Series slurry pumps are reliable in operation.
Reliability in operation

Specially developed features provide trouble-free operation and a minimum downtime improving the cost effectiveness.

  • Oversized high strength alloy steel shaft is carried in heavy duty grease lubricated bearings in a self-contained cartridge assembly
  • Double seal arrangement provides positive seal of bearings against contamination
  • Reliable gland seal options to meet individual requirements, using expellers, flushed glands or mechanical seals
  • Modular design and full interchangeability of parts minimizes stock levels
  • Back pull out feature allows ease of inspection and maintenance
  • Pumps and parts are manufactured under total quality management in ISO certified production units
Options

IMPELLER OPTIONS

  • Standard closed impeller
  • Induced flow (Vortex) impeller
  • Fully recessed induced flow (Vortex) impeller

SHAFT SEALING OPTIONS

Full flow

Use for suction conditions not suitable for centrifugal sealing when product dilution is not important. Full flow provides the longest packing wearing life.

Low flow

Use for suction conditions not suitable for centrifugal sealing when product dilution needs to be minimized. 

Standard expeller shaft seal

Used for no product dilution against positive suction head without leakage. 

Metso slurry mechanical seal

Used for zero stuffing box leakage or product dilution. Available as single slurry type mechanical seal or double mechanical seal with external barrier fluid required.

Special configurations for Orion Series slurry pumps.
Special configurations

Orion Series slurry pumps can also be supplied in a variety of special configurations:

  • HP – High Pressure: Same as HM with heavier duty case for higher pressure.
  • HG – Heavy-duty Gravel: Suction and discharge flanges are the same size and impeller has less vanes to pass larger material size.
  • HT – Heavy-duty Tunneling: Same as HM with special 90° elbow cast into the casing.
  • HH – High Head: Larger diameter impeller for a given flange sizes.
