Backwater Lifting Station Ecolift XL

With the Ecolift XL, KESSEL is now also supplying a hybrid lifting station for use in commercial buildings and multi-family homes. The advantage the hybrid lifting station has over traditional lifting stations is that Ecolift XL uses the efficiency of natural gradient during normal operation – the Ecolift XL only uses its pumps during times of backwater or flooding, pumping the building’s wastewater via a bypass directly into the surcharged sewer pipe.

In the event of backwater, the motor-driven backwater flaps of the new hybrid lifting station close and provide maximum flood protection to the building. The pneumatic level sensor assures accurate pump operation and the alarm sensor provides an additional back-up alarm. Ecolift XL is available with pumping capacities of 1.5 kilowatt to 4.5 kilowatt. In addition, KESSEL also offers solutions tailor-made to customer requirements. The hybrid lifting station can be used for free-standing set-up connected directly to the outlet of a grease separator for example, or for outdoor underground installation.

Despite the mechanical design and insulation of traditional lifting stations they are still a constant source of noise since every liter of a building’s wastewater needs to be pumped out. In contrast, the Ecolift XL uses the natural gradient to drain waste from the building and only activates the pumps during backwater. This means that pumping operation noise only occurs in exceptional cases. This is an advantage not only for apartment blocks with basement apartments, but also for commercially or public used buildings such as offices, schools, hospitals and residential homes for the elderly.

Professional advantages:

  • Maximum safety
    Up to 2 motor-driven valve systems for maximum safety.

  • Level detection
    Pneumatic level sensing and alarm sensor offer twice the reliability.

  • Control unit
    Comfort Plus control unit with display for full text display and USB port for read-out included as standard.

  • Pumps
    Wide range of pumps for all requirements. S1 pumps suitable for permanent running for pumping rainwater with 1400 W - 4500 W input power.

Installation in an inspection chamber also possible

Ecolift XL is integrated in a newly designed, high-quality, standard-compliant polymer inspection chamber which is suitable both for installation in the ground or in concrete. The chamber is resistant to groundwater up to 3 metres and can be built up to a height of five metres. The chamber is available with an access opening of 600 millimetres in diameter and now also in a new version with a diameter of 800 millimetres.

Professional advantages:

  • Modular
    Modular system with sectional chamber components height 250 mm / 500 mm. Infinitely variable chamber depth from 1500 - 5000 mm.

  • Low weight
    Easy to assembly due to the low weight of the polymer chamber components.

  • Upper section
    Vertically adjustable upper section available with Ø 600 mm or Ø 800 mm diameter with optional waterproofing connection flange.

  • Honeycomb structure
    Buoyancy-protected honeycomb structure, ideal for drilling up to Ø 160 mm, engineering chamber  handles groundwater depths up to 3000 mm.

  • Load class
    Available in a stainless steel class A/L15 (tileable or not tileable) or in load classes B and D.
