ISO Hydraulic Bare Shaft Pumps

Bare shaft design with no coupling required

  • Bare shaft design enables seamless integration with your preferred hydraulic motor
  • Female splined shaft and 2-bolt SAE B mounting provide direct connection to a suitable hydraulic motor
  • With no coupling required, alignment is no longer a concern, resulting in reduced maintenance and downtime
  • Compact footprint—approximately 200 mm shorter—achieved through direct motor coupling
  • Robust bearing housing with greasable, heavy-duty bearings ensures extended service life
  • Standard ISO 2858 layout allows straightforward installation

Stalker Pumps, based in Perth, WA, have been manufacturing high-quality pumping solutions since 1923. As the exclusive distributor, MTP supplies the full range of Stalker ISO 2858 pumps, spares and custom-built units from the Perth foundry.

The Stalker ISO Hydraulic Bare Shaft Pump is engineered to ISO 2858 and ISO 5199 standards and is purpose-designed for hydraulic-drive applications across mining, construction, chemical transfer and general industry. Unlike the standard bare shaft configuration, this hydraulic version is optimised for direct mounting to hydraulic motors, providing a compact, efficient and highly reliable solution for mobile or remote installations.

Material options include cast iron, aluminium bronze, 316 stainless steel and carbon/ceramic/NBR unbalanced mechanical seals. The ISO range is available in bare shaft, hydraulic bare shaft, direct-coupled and motor-pump configurations.
