Wet rotor circulators
Pump for hot for water circulation in pressurised closed circuit, or open circulation type, domestic heating and air conditioning systems.
Operating range: from 0,6 a 3,7 m3/h with head of up to 6 metres.
Pumped liquid temperature range: from -10 °C to +85 °C for sanitary uses, and +110 °C for other uses.
To avoid the formation of calcium, do not exceed 65 °C, and include a calcium removal system when the hardness of the water exceeds 15 French degrees.
Pumped liquid: clean, free of solids and mineral oils, non-viscous, chemically neutral, with properties similar to water (glycol max 30%).
Maximum operating pressure: 10 bar (1000 kPa).
Minimum suction pressure: the values are shown in the corresponding tables.
Installation: with HORIZONTAL MOTOR AXIS.
Special executions on requests: alternative voltages and frequencies.
Accessories: 1/2”F - 3/4”F - 1”F union connectors.
Copper piping welded union connectors: Ø 22 mm - Ø 28 mm.
Single body consisting of the cast iron hydraulic section and the wet rotor motor. Die-cast aluminium motor casing. Technopolymer impeller. Tempered stainless steel motor shaft on graphite bushings lubricated by the pumped liquid. Stainless steel rotor liner, stator liner and closing flange. Ceramic thrust ring, silicon seal rings, and brass air breather plug. The wet rotor asynchronous two-pole motor is protected as far as resistance, and does not require overload protection.
