Application

Construction

Gas handling centrifugal pumps of the series UEA are used for
trouble-free handling of pure or turbid, not aggressive liquids,
containing no solids.
The gas handling capability is used to handle mainly liquid gas
(LPG) and other hydrocarbon liquidate reshipment points and large
gas depots, fire extinguishing plants sprinkling and irrigation plants
emptying of fuel trucks filling of high tanks, refueling cars.
Centrifugal pumps of the series UEA with special NPSH inducer
stage are applied for trouble-free pumping under unfavorable
conditions at suction side. A special priming stage is able to absorb
eventually existing vapour from the suction side. The capability of
the pumps in this series to handle liquids at the boiling point, allows
a wide-ranging application when handling:

Casing pressure:
max. 40 bar up to size 8000 from -40 °C to 120 °C
max. 25 bar up to size 10000 from -40 °C to 120 °C
Pressure stages for higher temperatures acc. DIN EN 764-1

Hydrocarbon condensates
Hydrocarbon liquefied gases

Please note:
Technical rules and safety rules.
Casing pressure = zero delivery head + pos. suction pressure
Position of the branches:
Suction flange axially and discharge flange radially upwards.
Flanges:
At suction and discharge side the flanges correspond to DIN EN
1092 PN 25 and PN 40. Flange design with groove to DIN EN 1092
or bored to ASME B 16.5 possible.
Hydraulics:
Centrifugal hydraulic with special NPSH-impeller and gas priming
stage.
Bearings:
At suction side a liquid surrounded sleeve bearing, at discharge
side grease lubricated inclined ball bearings as per DIN 628. The
designation of this construction:.A
First grease filling for antifriction bearing is made in the factory.
Sense of rotation:
Clockwise when looking at the pump from the drive end.
Shaft sealing:
The shaft can be sealed either by single mechanical seal or by
double mechanical seal.

Design
Horizontal centrifugal pumps of the segmental type with closed
impellers and a suction stage. The suction stage is installed at
discharge side. It is arranged in parallel to the last liquid handling
stage and operates acc. to the sucking-through principle.
The design UEA has an axial inlet with NPSH inducer stage.
The axial thrust is compensated by single-impeller relief. The
remaining axial thrust is compensated by antifriction bearings of
sufficient size.
The vertically to the axis divided casings are sealed by O-rings and
connected through external casing connection screws.
