Total lift or backpressure (static head plus pressure in the return system) which must be below the motive fluid inlet pressure to

allow capacity to be achieved:-

Height (H) in metres x 0.0981 plus pressure (bar g) in return line, plus downstream piping friction pressure drop in bar calculated at a flowrate

of the lesser of six times the actual condensate rate or 30 000 litres/h.

Recommended filling head above the pump

Minimum filling head required
