A pump insert (1) for arranging in an accommodating space (104), the pump insert (1) comprising: a pump (10) comprising a pump chamber (15) and a delivery element (11) which can rotate about a rotational axis (D) and which is arranged in the pump chamber (15); an electric motor (20) comprising a rotor (21), which can rotate about the rotational axis (D), and a stator (22); and a drive shaft (30) which is mounted such that it can rotate about the rotational axis (D), wherein the rotor (21) and the delivery element (11) are connected via the drive shaft (30) in such a way that rotating the rotor (21) causes the delivery element (11) to rotate.

A fluid pump includes a pump element where rotation of the pump element generates suction at the inlet and pressure at the outlet to move fluid through a fluid path. An inlet orifice directs a portion of the fluid through the accessory fluid path that includes a low-restriction return path providing a continuous flow of the fluid through the accessory fluid path and to an outlet orifice. A circuit board housing includes a contoured portion and a PCB with a thermistor in communication with contoured portion. The continuous flow is directed between the contoured portion and the outlet orifice between a rotor and the outer wall. The low-restriction return path maintains a temperature of the continuous flow of the fluid within the contoured portion of the accessory fluid path to be similar to a temperature of the fluid in the fluid path.

A fluid pump includes a pump element in communication with an inlet and an outlet. Rotation of the pump element generates a suction at the inlet and pressure at the outlet. The suction and pressure cooperate to move a fluid through a fluid path. An accessory fluid path is in communication with the inlet and outlet. The accessory fluid path includes a thermistor in communication with the accessory fluid path. The thermistor monitors a temperature of the fluid within the accessory fluid path.

A modular fluid pump includes a stator having a plurality of stator teeth and windings that are positioned on the stator teeth. A rotor has a central shaft and substantially hemispheric ends and a plurality of magnets that define an electromagnetic communication with the windings A housing surrounds the stator and includes a fixed end cap that receives one of the hemispheric ends of the central shaft and defines a rotational axis of the rotor. A securing end cap that receives the other hemispheric end of the central shaft. The central shaft and the fixed and securing end caps define the rotational axis of the rotor. Engagement of the hemispheric end with the central shaft and the fixed and securing end caps maintains the rotor and the central shaft aligned with the rotational axis and balanced within the stator.
