Submersible Pump GRUNDFOS Unilift CC 7 A1 1x230V with float switch and 10 m cable

GRUNDFOS Unilift CC 7 A1 is a compact submersible drainage pump designed for operation on a single-phase 230 V mains supply. The unit includes an integrated float switch for automatic on/off control and comes with a 10 m power cable. It is intended for removal of clear or slightly dirty water from basements, sumps and other low-lying areas in residential and light commercial applications where reliable temporary or permanent drainage is required.

Advantages

The pump combines a compact design with corrosion-resistant materials suitable for water drainage. The integrated float switch provides automatic activation and prevents dry running by switching the pump off when water level drops. A 10 m cable offers flexibility in positioning the pump relative to the power source. The motor and impeller are engineered for continuous and intermittent operation in drain-down and transfer tasks, ensuring consistent flow performance for its class.

Suitable for

• Draining flooded basements and cellars
• Sumping and dewatering of small pits and cisterns
• Temporary removal of rainwater and seepage in residential settings
• Light commercial drainage where clear or slightly contaminated water is present

Key specifications

• Power supply: single-phase 230 V
• Integrated float switch for automatic on/off control
• Power cable length: 10 m
• Pump type: submersible drainage pump
• Designed for clear or slightly dirty water
• Compact and portable construction for easy placement

How to use

Place the pump on a stable surface at the lowest point of the area to be drained, ensuring the float switch can move freely. Connect the 10 m cable to a suitable single-phase 230 V supply with residual-current protection as required by local regulations. The float switch will automatically start the pump when water rises to the cut-in level and stop it when the water drops to the cut-out level. Avoid running the pump dry and periodically inspect the intake and impeller area for debris and sediment that can reduce performance.

Usage recommendations

For reliable operation, use the pump only for clear or slightly dirty water and avoid abrasive solids. Install residual-current device (RCD) protection on the supply circuit, follow local electrical codes, and perform regular inspections of the cable, float switch and pump housing. When storing the pump, clean and dry it thoroughly to prevent corrosion and prolong service life.
