Powerlift prefabricated pumping station
1 For your safety
Read the safety instructions before installing and operating the prefabricated pumping
station, in order to prevent personal injuries and damage to property.
1.1 Intended use
The prefabricated pumping station is used for collecting and automatic lifting of non-faecal and
faecal wastewater above the backow level. The wastewater is drained into the drainage sewer
safely for people and without damaging structures or contaminating the ground.
IMPORTANT
■The maximum wastewater temperature must not exceed 40 °C.
■The installation fittings and components (e.g. inlet immersion pipe, pressure pipe parts)
are designed for operation as a prefabricated pumping station. They are not designed
to be a step or foot board for people and storage e.g. heavy cleaning devices. The
bearing force is not designed for such purposes.
■The use of an access aid for accessing or entering the prefabricated pumping station is
anchored in the requirements of the employers' liability insurance association.
The prefabricated pumping station is intended for installation in the ground below the backow
level in the following types of projects:
■Drainage for sanitary rooms
■Drainage for rainwater surface areas
■Protection for separator plants, which are built into the ground, against backflow from
public sewers
Harmful substances must not be discharged into the prefabricated pumping station:
■Heavy metals, e.g. zinc, lead, cadmium, nickel, chromium
■Aggressive substances, e.g. acids (pipe cleaning agent with pH value below 4)
■Alkaline solutions, salts and condensates
■Cleaning products and disinfectants, washing-up agents and detergents in overdosed
quantities or quantities that result in disproportionate foaming
■Flammable or explosive substances, e.g. petrol, benzene, oil, phenols, solvent-based
paints, white spirits
■Solids, e.g. kitchen waste, glass, sand, ashes, fibrous material, synthetic resins, tar,
cardboard, textiles, greases (oils), leftover paint
■Liquid substances, which can harden, e.g. gypsum, cement, lime
■Ecocides, e.g. plant treatment and pest control products
■Wastewater from manure pits and keeping of livestock, e.g. liquid manure, slurry, dung

For your safety

■For level regulating for liquid filling levels: The
level can be optionally determined via pneumatic
pressure (with/without air bubble injection), an
external sensor (4 – 20 mA) or a float switch. The
motor contactor directly activates two pumps
up to max. 5.5 kW power. Furthermore, 5 relay
contacts are available for the output of fault
signals and messages. The operation and setting
is very simple. All values can be queried on the

Level sensor
Open back pressure
bell
All ■Measuring principle: pneumatic filling level
recording. When the liquid reaches the bottom
of the compression bell, the air within the bell is
compressed. A rising liquid level activates the
control. After pumping out it must be ensured that
the compression bell is ventilated (not the version
with air bubble injection).
■Utilisation: in highly contaminated, polluted and
viscous medium as well as Zone 1 + 2 potentially
explosive atmospheres.
■Restriction: not suitable for aggressive media and
temperatures higher than 40 °C.
■Housing: grey cast iron GG
■20 m pneumatic control pipe
Closed back
pressure bell
All With 40 m control cable
Float switch
(4 Units required)
Not for wastewater
containing faeces
■Knife principle: Microswitch (position dependent)
■Use up to 80 °C, not approved for use in explosive
hazardous areas
■Degree of protection: IP 68/2 bar
■Switching capacity 5 A/250 V, switching angle 10°
■Polypropylene housing
■10 m connecting cable
Level probe All ■4 - 20 mA output signal for hydrostatic filling level
measurement in water and wastewater.
■Very easy to clean and is ideally suited for waste-
water with the front flush-installed membrane (ATEX
II 2 G EEx ia IIC T6: XA131P/00/a3).
■Degree of protection IP68
■Utilisation for ambient temperature: -10 °C to +70
°C
■Measuring range: 0.1 – 0.4 bar
■20, 50 and/or 80 m connecting cable (bending
radius maximum 120 mm)
Air bubble injection In combination with open
back pressure bell
A compressor is integrated into the control line of the
open compression bell as a bypass via a T-piece. The
compressor permanently blows in air via the control line.
This therefore the back pressure bell from becoming
clogged by substances that form a oating layer (e.g.
fat).
Ex-barrier In combination with level
probe
■For separating potentially explosive and safe area.
The ex-barrier is an additional piece of equipment
whose purpose is to achieve safe isolation of intrin-
sically safe electric circuits from non-intrinsically
safe electric circuits. It contains limiting devices
with voltage limitation for two circuits.
■Maximum permissible ambient temperature: -20 °C
to +50 °C
Protection pipe for level
probe
All ■Total length 1,700 mm

2.3 Operating principle
Wastewater from the connected sanitary appliances ows via the inlet pipe and into the tank.
Level encoders assembled in the tank (sensors) are connected to the control. At a dened water
level, the pumps are switched on and off or a ood alarm is triggered.
The water level in the tank is shown in the display panel of the control.

Product Description

Powerlift prefabricated pumping station
If the water level reaches the baseload (BL), then a pump switches on and pumps the
wastewater through the pressure pipe above the “Pipe invert, backow loop” level. From there
the wastewater ows by gravity to the drainage sewer.
Two ball retaining valves prevent backow from the pressure pipe and into the tank.
If the water level falls to the pump OFF (OFF) level, then the pump switches off. With a set after-
running period (ARP), the pump remains activated and the water level continues to be lowered to
the after-running period OFF (ARP OFF) level.
The prefabricated pumping station is equipped with two pumps:
■With each new start, alternating operation is executed.
■If one pump fails, the second pump switches on.
■If the wastewater inflow is higher than the delivery performance of one pump and the
water level rises to the peak load (PL) level, the second pump also switches on.
