The Catalog

The MH Series Hydrapak is a pre-engineered, all-in-one hydraulic drive conditioning system designed to simplify hydraulic system design, installation, and operation in transport applications. 

 

By integrating all critical components into a single compact unit, the Hydrapak eliminates the complexity of traditional reservoir-based systems while improving cooling performance, reducing weight, and minimizing maintenance requirements.

With flow rates up to 60 GPM, pressure ratings up to 5000 PSI, and durable stainless steel construction, the MH Series establishes the standard for hydraulic cooling systems used across modern transport equipment.

Why It Matters

Hydraulic systems in transport applications must operate under demanding conditions, including: 

  • High ambient temperatures
  • Continuous duty cycles
  • Limited frame rail space
  • Vibration and road shock

 

Traditional reservoir systems introduce unnecessary weight, complexity, and inefficiencies. 

 

The MH Series Hydrapak solves these challenges by: 

  • Delivering efficient hydraulic oil cooling in a compact footprint
  • Reducing system weight to increase payload capacity
  • Simplifying installation with pre-engineered configurations
  • Minimizing maintenance and potential failure points

 The result is a more efficient, reliable, and cost-effective hydraulic system.
