DAB VS8/150

1~230 V, 50 Hz circulation pump

Pump for hot water circulation in hot water domestic systems of the closed and pressurised or open tank type. Also suitable for solar power systems.Single body formed of the bronze hydraulic unit. Die-cast aluminium motor casing. Technopolymer impeller. Ceramic driving shaft mounted on graphite bearings lubricated by the pumped liquid itself.

Stainless steel protective rotor sleeve, stator sleeve and closing flange. Ceramic thrust bearing, E.P.D.M. "O" rings.
The two-pole or four-pole asynchronous motor with wet rotor is self-protected for resistance. No overload protection required.

Techinal data:

• Operating range: from 0.6 to 5 m3/h with head up to 6.5 metres.
• Liquid temperature range: from +2°C to +60°C.To prevent condensation from forming inside the motor, the pumped liquid temperature must always be over the room temperature. To prevent scale from forming, the pumped liquid should not exceed 65°C and an anti-scale system should be fitted if the water is harder than 15 French degrees.
• Characteristics of pumped liquid: clean, free from solids and mineral oils, non viscous, chemically neutral, close to the characteristics of water (max. glycol 30%).
• Maximum operating pressure: 10 bar (1000 kPa).
• Installation: with MOTOR AXIS HORIZONTAL.
