Rexroth A11VO/190 Pump
The Rexroth A11VO/190 pump is designed for circulation of heating or cooling liquid. The A11VO series is available as a three-point, reverse rotation model and with a natural circulation option. This design enables the pump to be mounted directly on the heat exchanger due to its low weight, compact design and high efficiency.
Features
- Designed for application in mobile machines, such as tracked vehicles
- Two mutually independent flows and controls of both pump sides
- Short-sized pump for confined installation spaces through common port plate for both rotary groups
- High-pressure relief valves with integrated boost function
- Boost-pressure relief valve
- Combination of different nominal sizes in one double pump available
- Through drive for mounting of further pumps up to same nominal size
- Optional with pressure cut-off
- Flow direction changes when the swashplate is moved through the neutral position
- Swashplate design
