SEG grinder pumps are built tough and versatile
SEG grinder pumps 0.9-4 kW are the perfect choice for pumping untreated wastewater and toilet waste from single houses, small communities and less populated areas as part of a pressurised pipe network where sewer systems or gravitation systems aren’t an option. SEG grinder pumps are designed for reliability and efficiency and are very cost-effective. The capability for use with smaller pressure pipes means the pumps are cheaper to install and operate, more energy-efficient and reliable for years to come.
AUTOADAPT versions incorporate a controller, sensors and motor protection. Simply connect to the mains supply and the pump adapts automatically to the conditions in the pit.

How does one mount a float switch?
The float switch cable is to be attached to the discharge pipe in such a way that the remaining free cable length ensures a sufficient flow volume. The pit size should also be taken into account. In addition, it must be ensured that the depth of the pit is sufficient for the switch-on/switch-off spacing of the float pit and that the spacing between the pit bottom and the inlet is at least 60 cm.
What minimum fill level is required to properly operate the wastewater or deainage pump?
The EF and SE pumps are equipped with motors cooled by the surrounding pumped medium. In order for the motors to be adequately cooled, the EF and SE pumps must always be completely submerged in the pumped medium during operation. For applications where this is not possible, the fill level must never fall below half the height of the pump.
The KP and AP pumps, on the other hand, have motors that are cooled from the inside by the pumped medium flowing through the pump. For this ...
