Waste Water

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry’s standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

Design

Sewage lifting unit with solids separation system for installation in a building or concrete sump

Application

  • System for installation in an existing structure (building or concrete sump).
  • Sewage lifting unit with solids separation system for drainage of large residential estates and boroughs or as a replacement system for the refurbishment of existing large concrete sumps.

Special features / product benefits

  • Energy saving due to pumps with narrow ball passage, which produces better efficiency than with conventional sewage pumping stations
  • Considerably less susceptible to plugging as the pumps do not come into contact with the solids in the wastewater

Wilo-DrainLift M

Design

Sewage lifting unit with 1 or 2 integrated pumps

Application

Sewage lifting unit for drainage of residential housing and commercial buildings (e.g. restaurants, department stores, etc.). Raw sewage that cannot be piped to the sewer system through the use of natural inclines and sewage from toilet systems below the backflow level are to be piped to the public sewer system by means of an automatic lifting unit in accordance with DIN EN 12056/ DIN 1986‐100. Sewage containing mineral oils or explosive admixtures must be guided through oil precipitators and/or petrol precipitators; those containing fatty substances must go through grease traps and those with sand through grit chambers. In cases where the flow to the lifting unit must not be interrupted during normal operation, one lifting unit must be equipped with a second pumping unit that has the same performance capacity and switches on automatically when needed (DIN EN 12050‐1 A1).

Type key

Description/design

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

DrainLift M1/8:

Single-pump system with single-phase or three-phase AC motor for automatic operation. Switchgear with shock-proof or CEE plug, potential-free contact, integrated and mains-independent alarm and adjustable follow-up time.

RV version with non-return valve included in the scope of delivery.

DrainLift M2/8:

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 shock-proof or CEE plug, potential-free contact, maintenance interval display, early fault detection and integrated and mains-independent alarm and adjustable follow-up time.

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