Grundfos - TPED 50-360/2 A-F-A-BQQE-KDB Twin Head In-Line Circulator Pump - 415V - Three Phase - 567 Ltr/min. - Cast Iron

Single-stage, close-coupled, volute twin-head pump unit with in-line suction and discharge ports of identical diameter. The twin-head pump is designed with two parallel power-heads. The pump is of the top-pull-out design, i.e. the power head (motor, pump head and impeller) can be removed for maintenance or service while the pump housing remains in the pipework. Each power head is fitted with an unbalanced rubber bellows seal. The shaft seal is according to EN 12756. All pipework connection is via PN 16 DIN flanges (EN 1092-2 and ISO 7005-2). Each power head is fitted with a fan-cooled, permanent-magnet synchronous motor of identical size. Each power head is fitted with a fan-cooled asynchronous motor of identical size. The motor efficiency is classified as IE5 in accordance with IEC 60034-30-2.

Suitable for: Commercial air conditioning
