No compromise

The hydraulic design of the Grundfos S-tube® impeller ensures no compromise between free passage through the pump and high efficiency, keeping reliability high and clogging at a minimum.   

Suitable for vertical or horizontal installation, dry and submerged, without the need for external motor cooling.

Primary and secondary seal in one cartridge unit provides longer seal lifetime and easy fail-proof replacement in the field without special tools.

The moisture-proof plug design prevents moisture from entering the motor.
