* Maximum back pressure for TTT, PPT and PCT material versions: 10
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.
Data
Reproducibility
* for measurements taken under constant conditions, minimum 10 %
stroke rate and water at 20 °C - when installed correctly and with a back
pressure of at least 1.5 bar
The liquid ends are suitable for the following viscosity ranges:
