APPLICATION
The self-priming centrifugal pumps of series TKH/TLH are used,
when clear or turbid liquids, free from solid particles, are to be
handled reliably and trouble-free.
Because of their self-priming capability and owing to the multitude
of material combinations, the pumps cover a wide range of
applications in such fields as:
the supply of drinking and utility water for greater communities
and large industrial plants,
the handling of fuel in decanting stations,
and large tank plants
the construction of fire-extinguishing equipment,
the construction of cooling plants,
shipbuilding (ballast and stripping pumps),
the chemical industry and the petrochemistry
DESIGN
Horizontal, segmental type centrifugal pumps with shrouded
impellers and a priming stage arranged on the suction side. The
priming stage runs in parallel with the first liquid stage and
operates acc. to the mixed media separation principle during the
priming phase and in case of big gas portions..
As result of the separation of the gas before entering the first
impeller this is largely admitted with liquid. Finely divided gas
portions can be handled without problems. If during the priming
cycle, the counter pressure on the discharge side is below 0,5 bar,
the pumped-away gas is discharged into the delivery pipeline. If
the counter pressure is higher than 0,5 bar, then a separate gas
discharging device is required.
More detailed information can be obtained from Appendix TH - KS.
The programme includes 7 pump sizes ranging from one stage to
a maximum number of 9.

left, when looking at the pump
from the drive end.
Discharge orifice arranged
radially upwards.
Series TKH 8300 to 15300 Suction and discharge orifices
and TLH 15100: showing radially upwards.
Flanges:
The flanges are in compliance with DIN 2535/ PN 16.
Exception DN 200 (on the suction side of pump size TKH
15300) complying with DIN 2532 / PN 10 and DN 80 designed
