Abstract
A pump for a coolant circuit of an internal combustion engine of a motor vehicle includes a temperature sensor integrated into the pump for detecting the temperature of the fluid flowing into a pump chamber. The temperature sensor is inserted into a recess of a pump casing of the pump. The recess produces a reduced wall thickness (d) in the region proximate the temperature sensor. The reduced wall thickness improves the heat transition through the pump casing from the fluid to the temperature sensor and reduces the outlay in terms of production. Furthermore, the temperature sensor is arranged on a carrier material common to a control of the pump so that the susceptibility of the contacting of the temperature sensor to faults is reduced.
