Backflow
Waste water flowing back from the sewer into the
connected drainage piping
Certificate of decontamination
A certificate of decontamination is enclosed by the
customer when returning the product to the
manufacturer to certify that the product has been
properly drained to eliminate any environmental
and health hazards arising from components in
contact with the fluid handled.
EN 12050-2
European Standard for waste water lifting units
which are used to dispose of faeces-free waste
water occurring below the flood level of buildings
and sites. It defines general requirements as well
as principles of construction and testing.
Flood level
Maximum backflow level of waste water in a
drainage system
Hydraulic system
The part of the pump in which the kinetic energy
is converted into pressure energy
Pump
Machine without drive, additional components or
accessories
Pump set
Complete pump set consisting of pump, drive,
additional components and accessories
Submersible motor pump
Submersible motor pumps are floodable, closecoupled units which are not self-priming. The
pumps are usually operated completely
submerged. They may be operated outside the
fluid for short periods of time, until the minimum
fluid level has been reached.
Waste water
Water consisting of a combination of water
discharged from households, industrial and other
businesses as well as surface water.

Design
The pump is designed with an axial fluid inlet and an outlet parallel to the axis,
pointing upwards. (The outlet of Ama®-Drainer N 358 pumps is horizontal,
perpendicular to the axis.) The hydraulic system runs in common bearings and is
connected to the motor by a shaft coupling.
Function
The fluid enters the pump via an opening in the foot (8) and is accelerated outward
by the rotating impeller (7). In the flow passage of the pump casing the kinetic
energy of the fluid is converted into pressure energy. The fluid is pumped to the
discharge nozzle (1), where it leaves the pump. At the rear side of the impeller, the
shaft (4) enters the casing via the casing wall. The shaft passage through the cover is
sealed to the atmosphere with a shaft seal (6). The shaft runs in rolling element
bearings (3 and 5), which are supported by a bearing bracket (2). The bearing bracket
is linked with the pump casing and/or casing cover.
Sealing
The pump is sealed by three bi-directional shaft seals in tandem arrangement.
A lubricant reservoir between the seals ensures cooling and lubrication of the shaft
seals.
