Wet rotor electronic circulators
Low energy consumption electronic pump for water circulation in pressurised closed circuit, or open circulation type, domestic heating and air conditioning systems.
Operating range: from 0,4 - 4,2 m3/h with head of up to 8 metres.
Pumped liquid temperature range: from -10°C to +110°C.
Working pressure: 10 bar (1000 kPa).
Protection class: IP 44.
Insulation class: F.
Installation: with horizontal motor axis.
Standard power input: single-phase 1 x 230 V / 50/60 Hz.
Pumped liquid: Clean, free of solids and mineral oils, non-viscous,chemically neutral, with properties similar to water (glycol max 30%).
Special versions on requests: alternative voltages and/or frequencies.
Single body consisting of the cast iron hydraulic section, and the wet rotor motor. Die-cast aluminium motor casing. Technopolymer impeller. Ceramic motor shaft on graphite bushings lubricated by the pumped liquid. Stainless steel rotor liner, stator liner and closing flange. Ceramic thrust ring, ethylene-polypropylene seal ring and brass bleed cap. The wet rotor synchronous two-pole motor is controlled by a frequency converter, and does not require overload protection.
