Your advantages

• Flexible thanks to a height-adjustable and swivel-capable inlet connection
• Easy to use thanks to built-in switchgear
• Integrated non-return valve
• Operational reliability via high switching volumes and reliable level recording
• Suitable for continuous duty (S1) with the use of self-cooling motors

Construction

Description/construction

Fully submersible sewage lifting unit, ready for connection (flooding height: 2 mWS, overflow time: 7 days) with a collection tank that is impermeable to gas and water and that is equipped with a buoyancy safeguard. Centrifugal pump with vortex impeller.

DrainLift XL2:

Double-pump system for automatic operation (with automatic duty cycling, standby and peak-load operation). Due to the integrated double non-return valve, only one pressure pipe connection is required. Switchgear with CEE plug, potential-free contact, integrated and mains-dependent alarm. Pumps with integrated sheath current cooling.

Attention: The switchgear is not submersible and must therefore be arranged in such a way that it is overflow-proof.
