Auxiliary Pumps and Valves
The Bosch auxiliary pumps and valves are suitable for different applications, with a simple and easy installation design. In a voltage range between 12 V and 24 V, our products are also available with flow rate control via PWM. Our auxiliary pumps and valves are designed for operating mode S1 (continuous operation). These products are typically used in auxiliary cooling circuits.
