High-efficiency wet rotor pump for use in heat pump systems, particularly in the consumer circuit (heating and cooling) and in the brine circuit thanks to cataphoresis coating and fixed speed levels. Control types for optimal load adaptation can be preselected via the control button: fixed speed levels (I, II III) and constant differential pressure control (pc) 3-stage, optional control via external input signal possible (signal cable not included). Venting function available. Max. delivery head 8.4 m with a throughput of 1.1 m3/h, volume flow max. 3.5 m3/h with a delivery head of 2.2 m Max. pressure level PN 10 Energy efficiency EEI 0.21. Pitch 180 mm Connection voltage: 1/N/PE ~230 V, 50 Hz. Dimensions: H x D x W: 180 x 138 x 94 mm. Connection cable load 1.5 m and seals (2x) included.
