Grundfos Pumps’ TPE3 in-line pump features a permanent magnet motor, hydraulic efficiencies, a series of advanced control modes, multipump functionality, and easy install, monitoring and commissioning that boost system efficiency and deliver overall greater heating and cooling performance. Grundfos’ Flow Limiting Function eliminates the need for a pump balancing valve, reducing pressure loss. It also features a built-in heat energy meter that can monitor heat energy distribution and consumption, preventing excessive energy bills caused by system imbalances. 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. 630-236-5500; us.grundfos.com
