bar!
All figures refer to water at 20 °C.
Priming lift / priming pressure (dry) determined for empty suction line and
empty liquid end and as well as clean and moistened valves (the figures
are lower with valve springs).
The suction lift / suction pressure applies to filled suction lines and filled
liquid end - when installed correctly.
