This auto-start, variable speed pump is ideally to applications with higher flows. Variable speed pumps are also beneficial where these are big differences of flow between zones on the irrigation system, such as when large lawns and smaller borders are being watered. Variable speed pumps reduce the strain on the pump and increase efficiency by only spinning the impellers as fast as necessary to maintain pressure.
The unit has a built-in non return valve.. Requires buffer vessel to protect the pump. Install in a vertical position only.
Flow (m3/hr): 5.75@20m, 5.1@30m, 4.5@40m, 3.75@50m, In/Out: 1″ BSPF FLC amps: 5.0
