Applications To restore system pressure when the mains supply is insufficient, a pump may be used. However, to comply with water authority byelaws a break tank must be incorporated, as the pump is precluded from direct connection to the mains water supply The ESPA Sub-tank system has been designed to solve this problem. A fully automatic unit, the Sub-tank has a stainless steel submersible pump incorporated into the break tank giving space-saving advantages in small plant rooms. An in-line inverter with buit-in pressure transducer provides control. Electronics prevent starting without water. Digital displays show On line, Pump operating and Fault. Installation is straightforward with only three connections required.
227 Ltr actual capacity high density polyethylene break tank (BS4213). WRAS approved. Byelaws 30 top tank fitted with 1/2” ball valve complying with (Byelaws 11) type “A” air gap, rotecting incoming mains supply from a class 5 designated risk of contamination (Byelaws 25).
Inverter starts and stops pump automatically and supplies water at a constant pressure.
Prevents starting in the absence of water and avoids water hammer.
Inverter displays rotation, frequency and system pressure.
Adjustable start pressure: 0.8 - 9.0 Bar.
Maximum temperature 35°C.
The pressure vessel requires a pre-charge with air (0.3 – 0.5 Bar). This charge should be checked and adjusted every six months.
