M28 Pre-Engaged Hydraulic Starter

General Information

IPU’s ATEX-approved hydraulic start systems provide guaranteed reliability, no matter how challenging or unpredictable the environment is. This truly independent start method can be specified as the only starting system or as a back up to electric or air starting. The M28 can be oriented to suit almost any engine configuration. The flange of the standard model can be rotated to suit the engine and ancillary equipment. In special circumstances, a custom flange can be installed for particularly difficult configurations.
 
  • Multi-environment ATEX approval:
    • Gas
    • Mining
    • Marine
  • IPU’s starting systems can be class approved to numerous certification standards. This is done on a case by case basis according to customer specifications.
  • Flexible for any engine configuration.
  • Simple and low maintenance (only require replacing filter element and periodically check gas pre-charge and system pressure).
  • Is designed as a modular system. Spacers and pinions are common to IPU’s air starter as are the flanges which mount to the engine. This helps remote and offshore sites simplify stock-holding and improve interchange ability.
  • Simple installation:
    • Starter motor: can be purchased with the fittings appropriate to a specific engine.
    • Mini-pack: can be purchased incorporating the starter motor, accumulator, hand pump, foot valve, hoses and fittings in a self-contained unit.
    • Custom package: IPU’s custom packages make the starting system an integrated part of the engine it serves. By designing a custom package that suits a specific installation, IPU helps customers create compact and effective power systems.
  • Cast iron casing. ATEX regulations strongly discourage the use of aluminium in mining and other explosive situations because of the risk that it will feed a thermite reaction.
  • Pre-engaged hydraulic starters. To avoid the possibility of sparks being thrown off when the starter’s pinion engages. A pre-engaged hydraulic starter waits until the starter motor’s pinion has engaged with the engine’s ring-gear before spinning the pinion at high speed.
  • Non-spark pinions. Is available with beryllium-copper pinions to further reduce the risk of sparks when the pinion engages with the ring-gear. This is an optional extra safety precaution over and above the safety offered by a pre-engaged system.
