GRUNDFOS has improved the SOLOLIFT2 sewage pump units

A number of design changes have been made to the SOLOLIFT2 range of wastewater pumping units for apartments and private homes. SOLOLIFT2 C-3 models can now be used in systems with water softeners, thanks to improved materials. SOLOLIFT2 WC-1 and WC-3 are now even better suited for holding more water, thanks to their bigger tank, allowing them to be more efficient in handling blackwater.

Wastewater treatment plants

The SOLOLIFT2 series is designed to divert domestic wastewater when it cannot escape by gravity. There are five models in the range: WC-1, WC-3 and CWC-3 for pumping black and grey water out of basins, toilets, showers and so on., a P-3 and D-2 – for drainage of gray waste water from sanitary appliances. GRUNDFOS is constantly working on improving the design and extending the functionality of the equipment.


Ekaterina Semenova, engineer of household equipment department of GRUNDFOS LLC“We are always adapting products to the current market needs. Nowadays water softeners are popular, which are added to washing machines together with the powder to prevent limescale from settling on the heating elements. SOLOLIFT2 C-3 sewage lifting units are aggressive environments, and in order to prolong their working life in such conditions, GRUNFOS decided to use stainless steel for the motor, nuts and fixing screws. The molybdenum portion in the alloy is increased by 2.5%, which makes it resistant to corrosion, high temperatures and aggressive environments

As well as improving the reliability and durability of the SOLOLIFT2 C-3 units, performance has also been improved. In particular, the design of level switch has changed, which determines when the equipment will start. No longer need to dismantle the element to change settings: simply turn the level switch body to set the desired height.

SOLOLIFT WC-1 and WC-3 models have also been upgraded.


Ekaterina Semyonova, engineer of the household equipment department of GRUNDFOS LLC“We increased the distance between the bottom of the tank and the pump part. The vertical size of the intake tank has changed from 263 mm to 273 mm, which now holds more water, which means black waste is recycled more efficiently and cleaner. Optimal use can be achieved by installing SOLOLIFT2 with modern toilets equipped with economy cisterns with two buttons, one responsible for draining up to 4 liters of water, the other up to 7”.


All SOLOLIFT2 models have flexible connection sleeves and adapters for inlets and outlets, making it quick and easy
