Application

Design details

Self-priming centrifugal pumps of the TKH/TLH range are used for
pumping pure or turbid liquids containing no solid matter.
Due to their self-priming ability and the possible material combinations the pumps can be used in a wide variety of applications
such as:

Casing pressure:
Permissible max. casing pressures as a function of size and
number of stages in bar:
TKH 8000 - 15000
16 bar
TLH 15101 - 15105
16 bar

•

Please note:
Technical rules and safety rules.
Casing pressure = zero delivery head + pos. suction pressure

•

•
•
•

fuel handling in places of trans-shipment and on large tank
farms
industrial and municipal potable water and service water supply
fire fighting equipment
manufacture of cooling equipment
in the shipbuilding industry as bilge and ballast pumps
chemical and petrochemical industries

Nozzle position:
TKH 8000 to 15000
and TLH 15100:

Suction and delivery nozzles radially
upwards.

Flanges:
Flanges according to DIN EN 1092-2 / PN 16.
Flange design according to ASME is possible.
Hydraulic:
Centrifugal hydraulic with special NPSH-impeller and gas priming
stage. Gas priming stage designed to side channel or liquid ring
vacuum principle.

Design
The horizontal ring-section type centrifugal pumps have closed
impellers and a priming stage. The priming stage is located on the
suction side parallel to the first liquid stage is used during suction
operation or according to the mixture separation principle. If the
liquid handled contains a lot of gas. The gas is separated and
largely removed before the liquid enters the first impeller. Finally
distributed quantities of gas pose no problem to pumping
performance. When during suction there is 0.5 bar back-pressure
on the delivery side the gas sucked is pumped into the delivery line.
If the back-pressure value is higher a separate gas discharge is
necessary.

Bearing:
The TKH 8000 to 15000 are equipped with a plain bearing and a
deep groove ball bearing. TLH 15100 has a double-row angular
contact ball bearing according to DIN 628 and a deep groove ball
bearing. All deep groove ball bearings conform to DIN 625. All antifriction bearings are grease-lubricated. Pumps are provided with
the initial supply of grease.
Direction of rotation:
Clockwise, when viewed from drive end.
Shaft seal:
The shaft sealing consist of mechanical seals.
