2. General
2.1 Application / Installation
The Aqualift F Pumpstation is designed to automatically pump
wastewater (with or without sewage collected below the outgoing
sewer level) according to the requirement of DIN 1986
into a septic system or public sewer piping. This system is only
for use with wastewater draining from single and multi-family
homes, commercial buildings, hotels, restaurants, hospitals,
schools or similar buildings. In circumstances where the interruption
of wastewater flow is not allowed or desired, a twin
pump system (Pumpstation Aqualift F Duo) is required in which
the second pump will activate during times of heavy flow or if
the second pump is not operating for any reason.
The KESSEL Pumpstation Aqualift F is designed for outdoor /
underground installation. Pumps are equipped with macerating
blades which cut all soft objects into smaller pumpable pieces.
Due to the cutting blades, outlet pipes of DN 40 or larger may
be connected to the outlet of the Pumpstation
Aqualift F. Objects in the wastewater which could damage or
cause wear and tear on the cutting / macerating blades should
not come in contact with the pumps. The system is designed
to handle continuous wastewater temperatures up to 40 deg C
(104 deg F).
The KESSEL Aqualift F Pumpstation is delivered in the following
variations:
• As a mono unit with a single pump or as a duo unit with twin
pumps
• With pumps with various strengths (kW)
• In a KESSEL Inspection Chamber with an internal width of
800mm or 1000mm
• With installation depths from 1.5 to 5.0 meters
The pump base, gate closure valves, non-return flaps, pressure
pipe connection and float switches have already been
installed in the chamber base. The pumps, the additional inspection
chamber sections and the control unit are delivered
not installed in the system. Depending on the size of the
pumps, the pumps are either delivered inside the chamber’s
upper section or on a separate pallet. The pumps should be
installed in the chamber only after the chamber has been
completely installed.
EX
In order allow any collecting explosive gases
to disperse, adequate ventilation is required.
