TECHNICAL DATA Output: max. 220 m³/h Head: max. 420 m Speed: max. 3600 rpm Temperature: -40°C to +80°C Casing pressure: PN 40 up to size 8000 PN 25 from size 10000 Shaft sealing: mechanical seal Flange connections: DIN 2501 PN 40 resp. PN 25 Option : ANSI 300 lbs Sense of rotation: clockwise looking at the drive side Certification : ATEX 94/9/EC Ex II 2 G c T1-T5 GOST APPLICATION 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 two phase handling capability has led to a broad application for supply with general use for several LPG applications. Handling of fuel at reshipment points and large tank plants. Handling of liquid gas at reshipment points and large gas depots, fire extinguishing plants sprinkling and irrigation plants emptying of fuel trucks filling of high tanks, airfield refuelling cars. Centrifugal pumps of the series UEA with NPSH inducer stage are applied for trouble-free pumping under unfavourable conditions at suction side. The capability of the pumps in this series to handle liquids at the boiling point, allows a wide-ranging application when handling: LPG Hydrocarbon condensates Hydrocarbon liquefied gases 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 are compensated by antifriction bearings of sufficient size. A hydraulically favourable re-routing is done by means of guiding . devices in the stage casings. The vertically to the axis divided casings are sealed by O-rings and the connected through external casing connection screws. A special priming stage separate and eliminate disturb gas phases.
CONSTRUCTION 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 as per DIN 2401 Please note: Technical rules and safety rules. Casing pressure = zero delivery head + pos. suction pressure Position of the branches: Suction flange axially and discharge branch radially upwards. Flanges: At suction and discharge side the flanges correspond to DIN
2535 PN 40 resp. DIN 2534 PN 25. Flange design with groove to DIN 2512 or bored to ANSI 300 possible. Hydraulics: Centrifugal hydraulic with special NPSH-impeller and gas
priming stage Bearings: Serie UEA - 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 stuffing box or standard mechanical seal. Special for liquid gas: Designation DNE: Balanced standard single mechanical seal
with throttle bush, with internal flushing lower. Temperature limit: -40 °C
Designation RBG: Balanced tandem double mechanical seal
Flowserve 610/610, 40 bar, Temperature limit: -25 °C, mechanical seal with internaland external

An installation of a bypass valve is recommended to ensure that the maximum pressure and admissible minimum flow of the pump is maintained. In order to compensate for the fluctuation in vapour pressure over the seasons this valve is designed as back pressure-regulated bypass valves. That means, this valve is opening at a set differential pressure of the pump, seasons independent. Minimum flow by free flow control valve: Used if operating pressure is < 1 bar below max pressure, minimum flow less than 25 % of operating flow! If a by pass valve can not be used the of admissible minimum flow can be controlled by a free flow control valve . This valve is designed for automatic control of the required pump minimum flow. The minimum flow should be less than 25 % of max. flow.

An installation of a bypass valve is recommended to ensure that the maximum pressure and admissible minimum flow of the pump is maintained. In order to compensate for the fluctuation in vapour pressure over the seasons this valve is designed as back pressure-regulated bypass valves. That means, this valve is opening at a set differential pressure of the pump, seasons independent. Minimum flow by free flow control valve: Used if operating pressure is < 1 bar below max pressure, minimum flow less than 25 % of operating flow! If a by pass valve can not be used the of admissible minimum flow can be controlled by a free flow control valve . This valve is designed for automatic control of the required pump minimum flow. The minimum flow should be less than 25 % of max. flow.
