OPERATING PRINCIPLE The PumpBuddy® will be closed when both weights are submerged (maximum water level). The valve will remain closed until the bottom weight is exposed (minimum water level). The valve will then open and remain open until the maximum level is reached.
  • Minimum temperature: 1˚C.
  • Tank valves must be insulated to protect the valve where the temperature can get below 1°C (minimum service temperature).
  • Maximum temperature: 60˚C.
  • Minimum inlet pressure: 55 kPa (8psi).
  • Maximum inlet pressure: 1200 kPa (175psi).
  • New Zealand Pat. Nos. NZ535912B and NZ560561B
  • Australian Pat. Nos. AU2005220285B2 and AU2007205772B2
