The pressure on the discharge side needs to be at least 1.5 bar higher than the pressure on the suction
side. We therefore recommend installing a back pressure valve on the discharge side to adjust the
increased pressure. This will avoid excess pumping.
*
- Suction lift with a filled suction line and filled liquid end. With
self-degassing dosing head with air in the suction line.
** - Priming lifts with clean and moist valves. Priming lift at 100%
stroke length and free drain or opened vent valve.
*** - The given performance data constitutes guaranteed min‐
imum values, calculated using water as the medium at room
temperature. The bypass connection with a self-degassing
dosing head SEK is 6x4 mm.
*** - The stated performance data represents minimum values
calculated using water as the medium at room temperature.

- The connector width is 6 mm with SST material versions.
Metering pumps with dosing heads for higher-viscosity (HV) media
have a 10-20% lower dosing rate and are not self-priming. Con‐
nector G 3/4-DN 10 with hose sleeve d16-DN10.
