* - Suction lift with a filled suction line and filled liquid end. With self-
bleeding dosing head with air in the suction line.
** - Priming lift with clean and moist valves. Priming lift at 100% stroke
length and free outlet or opened bleed valve.
*** - The given performance data constitutes guaranteed minimum
values, calculated using water as the medium at room temperature.
The bypass connection with a self-bleeding dosing head SEK is
6x4 mm.
*** - The given performance data constitutes guaranteed minimum
values, calculated using water as the medium at room temperature.
1 - The connector width is 6 mm with SST material versions.
Beta b Metering pumps with dosing heads for higher-viscosity media (HV)
have a 10-20% lower capacity and are not self-priming. Connector
G 3/4-DN 10 with hose nozzle d16-DN10.
Data
Capacity range of the series
Reproducibility
* - at max. stroke length and max. operating pressure for all material
versions
** - at constant conditions and min. 30 % stroke length
As the self-bleeding liquid end is used with outgassing media and when
operating with air bubbles, no dosing accuracy or reproducibility can be
provided.
The recommended minimum stroke length with self-bleeding dosing
pumps is 50 %.
The liquid ends are suitable for the following viscosity ranges:
Version Range
standard 0 ... 200
With valve springs 200 ... 500
Self-bleeding (SEK) 0 ... 50
HV (highly viscous) 500 ... 3000*
* Only when the installation is correctly adjusted
