The Bosch Rexroth UPE2-1X/11FR195/3A-1V+R900241988 (R900705308) is a high-performance clamping and drive module designed for the supply of hydraulic fluid to various hydraulic circuits. This compact and efficient unit is ready for connection upon delivery, featuring an aluminum housing that incorporates either a radial piston pump or an external gear pump, along with an oil-immersed motor. The motor's stator is securely pressed into the housing, ensuring effective heat dissipation to the exterior wall and maintaining operational temperatures below the maximum permissible level.
Engineered for vertical installation, the module includes four through holes at the tank bottom for secure mounting. It supports both short-time operation and intermittent operation modes, with duty cycles adjusted based on power output and environmental conditions to avoid surpassing a safe operating temperature.
The UPE2-1X/11FR195/3A-1V+R900241988 can optionally be outfitted with additional features such as electric oil level and temperature monitoring systems, a breathing filter, and complete hydraulic control capabilities. The module's design allows for integration with other attachment modules such as basic module G (integrated pressure relief valve), directional valve module W (for controls using valves with DIN porting pattern A), and seat valve module S (comprising pressure relief block, control blocks, and an end block). These modules can be combined to suit specific control requirements detailed in the data sheet for Control block for clamping and drive modules type IHA.
With its low noise output, compact design, wide application range, and numerous variant options, this clamping and drive module is well-suited for various industrial uses. It boasts a drive power of 0.75 kW, belongs to component series X, and can handle a maximum operating pressure of 280 bar. The unit emphasizes safety during operation due to potential heating risks—highlighting the importance of adhering to proper usage guidelines.

The UPE 2 clamping and drive module constitutes a complete drive system which is delivered ready for connection. It is used for the hydraulic fluid supply of hydraulic circuits.
For reasons of thermal loading, the clamping and drive module is to be operated in short-time operation and intermittent operation. The duty cycle is to be selected dependent on the power output and the environmental conditions so that the maximum admissible operating temperature of 80°C is not exceeded.
The clamping and drive module basically consists of the aluminum housing, the pump (radial piston pump or external gear pump) and the oil-immersed motor. The stator of the oil-immersed motor is pressed into the aluminum housing. It leads the winding heat directly to the exterior wall of the aluminum housing.
For the installation, four through holes for the mounting screws have been provided in the tank bottom. The clamping and drive module is to be operated in vertical installation position.
Optionally, the UPE 2 clamping and drive module can be equipped with an electric oil level and oil temperature monitoring, a breathing filter and a complete hydraulic control (see 51144).
Attention!
The clamping and drive module may heat up during operation ⇒ Risk of injury!

Electro-magnetic compatibility of devices (EMC)
According to the “Act on the electro-magnetic compatibility of devices (§2, subsection 4)” and the EEA Directive, the clamping and drive module is no operationally reliable device. In order to prevent electro-magnetic interferences that might occur, interference suppression elements by Murr-Elektronik in 71570 Oppenweiler are recommended.
E.g. type 23050, 3 x 400 V AC, 50 - 60 Hz
