More than 40 years, Danfoss has been developing and producing cutting-edge parts and systems for mobile machinery. Danfoss has become a recognized supplier offering high-quality products.

The MP1 Series Hydrogen - the future is here. And this is just the beginning of a new generation of regulating hydrogenerators into a closed circuit. The MP1 Series is designed on the basis of years of experience in the field, which has resulted in high reliability, long service life, great modularity and excellent maneuverability of these hydrogenerators. Everything has yet to achieve great compactness and minimal dimensions. All electrical controls are compatible with the Danfoss PLUS + 1® controllers platform - this provides rapid development and implementation of customer control.

Basic properties

Designed to achieve high quality and high reliability 

• a uniform concept across all sizes of hydrogenerators ranging from 28 to 45 cm³
• single-piece hydrogenerator body -minimalisation of leakage probability (oil flow) a technologically advanced cylinder block and a servo system
• low friction bearings for precise control with low hysteresis and high repeatability

Increased overall efficiency

• increased efficiency of the hydrogenerator
• lower pressures needed for control - lower own consumption

Management options

• electro-hydraulic control are EDC (electrical proportional to mechanical feedback) and FNR (forward / neutral / reverse)
• manual control of MDC (mechanical feedback with mechanical feedback)
• common servoventiles across all sizes

Modularity

• joint servo feeders, filling hydrogenerators and auxiliary mounting flanges across all sizes
• simple and fast conversion to the required configuration
