Break Tank & Pump MIDI-3A AB 230 V

Wall mounted break tank and pump assembly with Fluid Category 5 protection by virtue of the integral Type AB air gap complying with BS EN13077: 2003. The set is intended for light industrial use and is housed in a stainless steel cabinet ready for wall mounting in a frost free environment. The primary purpose is to provide backflow protection in accordance with the new Water Regulations. The Midi-Break® also provides cold water at a known outlet pressure. The unit is quiet since the pump is mounted on anti-vibration mounts with flexible stainless braided internal hoses. Automatic pump control is by means of a pressure vessel, industrial pressure switch and a flow sensor. This system provides reliable pump operation with the minimal amount of starts. The pump has a soft start feature, which avoids water and electrical surges. The pump is protected via low level float switch in the cistern.
