EHP / Electrohydraulic Pump
-
The Electro-Hydraulic Pump (EHP) kits are designed for hybrid electric and all electric mobile applications. EHP systems consist of an electric motor directly coupled to an hydraulic pump controlled by a high performance mobile hardened drive. Parker's global expertise in hydraulic, electric motor and drive technologies is brought together in the EHP to create a system that has been optimally adapted to the customer requirements. Selecting the required EHP could not be simpler. In fact, just three parameters are required to select the right EHP specification for the application.
These are:
• Flow
• Pressure
• Voltage -
The standard system consist of a:
Low voltage drive or High voltage drive + Synchronous motor (GVM) or Low voltage induction motor + Hydraulic T7 vane pump (other pump technologies on request). The EHP range provides the necessary expertise in all of the different technologies.
Features:
• Complete Electro-Hydraulic Pump solutions
• Pre engineered system with fully validated pressure, flow and voltage characteristics
• Wide range of motor/pump combinations with large voltage ranges to adapt to every battery pack
• Drives, Motors and Pumps perfectly mechanically matched (no need for extra adaptors)
• Low inertia PMAC motors and vane pumps
• Cost effective power steering solution (induction motors)
Applications:
• Electric power steering
- Buses and Coaches
- Vocational vehicles
• Electro-Hydraulic systems and circuits
- Street sweepers
- Construction
- Material handling
- Refuse trucks
- Agricultural equipments
