Grundfos TPE3 Circulation pump 40-120

Single-stage dry runner pump with volute casing and inline suction and pressure port with the same diameter. The pump is of the top-pull-out design, i.e., the pump head (motor, top piece, and impeller) can be dismantled for maintenance and service without affecting the pump casing's pipe connections. The shaft seal complies with DIN EN 12756. Pipe connection is via PN 16 DIN flanges (EN 1092-2 and ISO 7005-2). The pump is equipped with a jacket-cooled synchronous motor with permanent magnets. Motor efficiency is classified as IE5 in accordance with IEC 60034-30-2. The motor has a frequency converter and PI controller in the terminal box. This allows step-less regulation of the motor speed and thus adaptation of the performance to a given need. The pump is equipped with a combined temperature and differential pressure sensor.
