Wet rotor circulators
Pump suitable for vector fluid circulation in solar panel systems. VSA wet rotor circulators are capable of ensuring correct operation also with high glycol percentages (concentration up to 60 %).
Operating range: from 0 a 3,6 m3/h with head of up to 6 metres.
Pumped liquid temperature range: from -10°C to +110°C (TF110).
For all models, temperature peaks up to 140 °C.
Pumped liquid: clean, free of solids and mineral oils, non-viscous, chemically neutral, with properties similar to water (glycol max 60%).
Maximum operating pressure: 10 bar (1000 kPa).
Installation: with HORIZONTAL MOTOR AXIS.
Protection class: IP 44.
Insulation class: F.
Single body consisting of the cast iron hydraulic section, and the wet rotor motor. Special cataphoresis paint coating on the pump body, which guarantees resistance to the aggression of the glycol. Die-cast aluminium motor casing. Technopolymer impeller, tempered stainless steel motor shaft on graphite bearings 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. Two-pole asynchronous motor with squirrel cage rotor, designed for three-speed operation through a special selector in the terminal box, in order to adapt the operation of the circulator to the characteristics of the system.
