Grundfos has introduced the TPE3 in-line pump. The pump showcases a permanent magnet motor, a series of advanced control modes, multi-pump functionality, monitoring and commissioning, and more.  According to the company, Grundfos’ Flow Limiting Function eliminates the need for a pump balancing valve and thereby reduces the pressure loss. This improves the overall performance of the system and reduces initial costs. Moreover, it features a built-in heat energy meter that can monitor heat energy distribution and consumption, preventing excessive energy bills caused by system imbalances.

TPE3’s integrated Delta T control also aims to cut down on the costs of a differential temperature sensor, as it can operate based on the measured difference between flow temperature and return temperature. This is done via the built-in sensor and connecting one external sensor directly to the TPE3, which allows the pump to take charge of the system’s need for flow based on differential temperature.

Wireless technology enables the TPE3 to connect with up to four single TPE3 pumps. They can be controlled jointly in either cascade mode, alternating mode, or duty/standby without the need for any other pump controller unit.
