Short rotor shaft Compact motor construction with short rotor shaft reduces vibrations. Increases efficiency and lifetime of shaft seal and ball bearings.

Double mechanical shaft seal Efficient single-unit cartridge shaft seal system ensures longer operating time and less down-time. Easy to replace in the field without use of special tools.

Replaceable wear ring Easy replaceable stainless steel wear ring on single-channel impeller and rubber seal ring in the pump housing enable maintaining maximum pumping efficiency without replacing impeller.

Construction Extremely robust construction, with a smooth surface which prevents dirt and impurities from sticking to the pump.

Stainless steel clamp Unique stainless steel clamp assembling system enables quick and easy disassembly of pump from motor unit. No tools required. Provides easy access for service and inspection.

Modular design Each motor size fits several pump sizes with single-channel impeller hydraulics.

Operating conditions The Grundfos SL1 pumps are suitable for continuous submerged operation with a liquid level to the top of the motor, or intermittent submerged operation with a liquid level to the middle of the motor.

Explosion-proof versions For applications involving a risk of explosion, or where otherwise required, explosion-proof versions of the Grundfos SL1 pumps are available.
