Willett Pump Technical Details

Performance Data

Simplex pumps will give flow rate up to 2100 litres / min (~555 gmp). Larger rates are achieved by multiple (manifolded) units operating with electronic sequencing, giving controlled constant flow output.

The multiple pumps operate with a single hydraulic power pack and may optionally include an integrated stand-by power pack for economy and continuance of operation.

All data are based upon water at 20 deg C. Pumps are available for higher pressures and flow rates. As part of our policy for continual development we reserve the right to amend the specification without notice. Pumps fitted with chemical dosing cylinders require larger motors.
