PUMP UNIT FOR STRATIFIED LOADING
Compact fully assembled pump unit to supply the heat produced by a solar thermal system with High Flow or Low Flow operating mode. Equipped with diverting valve operated by controller and placed on the supply way of secondary circuit. It is supplied fully insulated and pre-wired, with preprogrammed controller and it allows a fast and easy mounting.
The unit consists of:
Primary solar circuit
• Flow meter with flow regulation with filling and draining valves. Alternatively a digital flowmeter is also available.
• Synchronous solar high efficiency circulating pump.
• 3-way return ball valve with 10 mbar check valve supplied with in-handle thermometer.
• Safety unit 6 bar with ø50 mm 0-10 bar pressure gauge with 3/4” male connection to the expansion vessel. End of drain side: 3/4” F.
• Supply ball valve with 10 mbar check valve supplied with in-handle thermometer.
• Deaerator made of brass with automatic air-vent valve and isolating valve.
Heat exchanger
• Weld-braised plate heat exchanger made of stainless steel AISI 316 suitable for several powers.
Secondary circuit
• Diverting valve.
• TÜV safety valve 3 bar, 50 kW. End of drain side: 3/4” F.
• Synchronous solar high efficiency circulating pump.
EPP insulation box (Dimensions: 576x585x190 mm).
A special back plate fixes the unit to the insulation box and allows a quick fitting to the wall.
