Pump esp. motor driven centrifugal pump with sensor determining pressure differences

摘要

The pump is provided with a sensor (14), for determining the pressure differences between two pump measuring points esp. between the suction and the pressure sides of the pump. The sensor and the lines (6,7) leading from the measuring points to the sensor, are located inside the pump housing (1). The sensor and the lines lie inside a wall of the pump housing. The sensor is arranged in a component (9), which lies in a recess (5) and esp. is exchangeable. The component can be screwed in to the recess. The component has a cylindrical outer surface and is esp. stepped.
