Submersible dirty water pump GEKO 81420 with grinder and float switch

The Submersible dirty water pump GEKO 81420 with grinder and float switch is a compact, portable electric pump designed to move and macerate contaminated water containing suspended solids. It combines a robust pumping unit with an integrated grinder to reduce debris size before discharge, and a float switch for automatic start/stop control. The pump is intended for temporary or mobile use in drainage, dewatering and removal of wastewater from basements, construction sites, garden ponds and other locations where solids and fibers may be present.

Advantages

This dirty water pump features an integrated grinder that helps prevent blockages by shredding solids and fibrous material before they reach the impeller. The built-in float switch enables automatic operation according to water level, reducing the need for manual control and minimizing the risk of dry running. Its compact design and portable weight make it suitable for quick deployment on site, and the construction materials offer resistance to abrasive particles typically found in contaminated water.

Suitable for

• Draining flooded basements and garages
• Dewatering construction pits and trenches
• Removing dirty water from garden ponds and outdoor areas
• Pumping wastewater containing debris, leaves and light solids

Key specifications

• Type: submersible dirty water pump with integrated grinder
• Operation: automatic on/off control via float switch
• Application: pumping and maceration of contaminated water with solids
• Design: compact, portable for temporary or mobile installation
• Discharge compatibility: suitable for water with suspended solids and fibrous debris

How to use

Place the pump on a stable surface within the flooded area or pond, ensuring the intake is submerged. Connect the pump to a suitable power source following safety requirements for outdoor electrical equipment and verify the float switch is free to move. Route the discharge hose to an appropriate drainage point. When water level rises, the float switch will activate the motor and the grinder will macerate solids before they are expelled. After use, disconnect power, lift the pump out of the water and flush the unit if necessary to remove trapped debris; inspect and clean the grinder area according to maintenance instructions.

Usage recommendations

Use appropriate protective equipment when handling contaminated water. Avoid pumping highly viscous fluids, thick sludge or large solid objects that exceed the pump's maceration capability. Regularly inspect and clean the grinder and impeller area to maintain performance and prolong service life.
