Whether hot water from commercial kitchens, water containing faeces from public sanitary areas or wastewater from sinks or coffee machines from the gastronomy sector, there is the right pump technology made in Germany by Pentair Jung Pumpen for every application.
When are lifting units used?
Lifting units are always used when the gradient is not sufficient to dispose of the wastewater in the existing wastewater pipe. They are also needed if the wastewater pipe is far away from the point where the wastewater is produced. They also bridge long conveying distances. Wastewater that accumulates below the backwater level (below the top of the road), e.g. in cellars or other basements, is pumped into the public sewer via lifting units. If the systems are correctly installed via a backwater loop, they also provide backwater protection. Water that accumulates when the public sewer becomes blocked or after heavy rainfall cannot be pushed back into the building. This is where physics works, because if the backflow loop is above the height of the top of the road, the water in the pipe cannot rise above this height and therefore cannot flow back. Drainage during backwater is however possible as the lifting unit pushes the water out. This is the great advantage over backwater valves, where drainage is not possible during backwater.
The right lifting unit for every case
Depending on the quantity and type of wastewater, different systems are used:
1. Disposal of sewage containing faeces
Sewage lifting units are necessary if sewage from public sanitary facilities is produced in the basement. The wastewater flows into the tank and is pumped from there into the public sewer. In public buildings, it is important and also mandatory that the wastewater disposal system functions reliably. To ensure this, a duplex system should always be installed. If one pump fails, the other takes over. Depending on the amount of wastewater produced, suitable systems are offered (compli 1200 and compli 1500 see pictures 1 and 2).
2. Disposal of wastewater ( without faeces)
If wastewater accumulates e.g. in tea kitchens, from coffee machines or from washbasins in the basement and therefore cannot run off in a free gradient, then small lifting units are the solution. Compact systems are ideal here, which can be easily accommodated in base units or pre-walls due to their small size. Different pumps are used depending on the amount of wastewater produced (Hebefix Plus see picture 3).
- Disposal of hot water
These systems have to withstand high temperatures and are therefore made of heat-resistant materials. This applies to both the tank and the pump. Despite high water temperatures, the plastic container must not deform or leak. For the submersible pump, the casing as well as the outlet pipe must withstand hot water (Hebefix 100 H see picture 4).
- Disposal of condensate
Lifting units used for the disposal of condensate from ovens, freezers or air conditioning systems must meet special requirements. Both the plastic container and the pump must be heat-resistant and at the same time resistant to aggressive condensate. Special materials are used for this purpose (Hebefix Mini see picture 5).
Quality is ultimately decisive in all applications, because pump failures are expensive in the commercial sector. The more reliable and trouble-free the systems, the less downtime due to repair work is to be expected. Plug-and-play systems are complete systems that require relatively little installation effort and are therefore easy to install. It is important to select the right lifting unit for the respective application. The decisive factor here is which medium (condensate, hot water, water containing faeces or pure wastewater) is to be pumped in which quantity over which distance.
