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.

If the pump is fitted with an SER head and priming pressure is being applied, then the pump may only be
operated in Automatic OFF mode.
* - The capacity can significantly fall at pressures above the
nominal pressure.
*** - with stainless steel design 6 mm connector width
**** - with stainless steel design 12 mm connector width
***** - The SER valve is only approved up to a pressure of 10 bar.
We recommend operating a pump with a SER valve of
between 1 ... 7 bar.
1 - Suction lift with a filled suction line and filled liquid end.
With self-degassing dosing head with air in the suction line.
2 - Priming lifts with clean and moist valves. Priming lift at
100%
stroke length and free drainage or opened vent
valve.
3 - The given performance data represents 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.
4 - These pump types are also available with dosing heads for
higher-viscosity media (HV). The pump types have a
10 ... 20% lower capacity and are not self-priming.
All data is calculated with water at 20 °C.
