EDUR-liquefied gas
pumps are compact, high-performance pumps for the supply of liquefied gases in
applications with high pressure differences. They reliably and safely fulfill
the highest requirements and achieve superior efficiencies during the process.
Fields of Application
and Conveyed Fluids
EDUR-liquefied gas pumps
are required for unloading, refuelling, transferring and filling
processes. The requirements for a liquefied gas pump are high: high
pressure differences, handling of gas contents, low NPSH (Net Positive Suction
Head) values, low-pulsation supply, low noise emission and ATEX
conformity. Users of liquefied gas pumps expect safe supply of liquefied
gas mixtures, mastering outgassing and fluctuations of the vapour pressure
and high pump efficiencies. The efficiency grade
of the liquefied gas pump leads to a low energy consumption, smaller drive
units and relatively compact pumps.
EDUR-liquefied gas pumps are
used at different positions within the transport process. Applications are
found within tank plants, tank trucks, refrigerating
installations, in the beverage
industry and in the process technology as
well as in ship building. The pumps ensure a safe
distribution of liquefied gas along the entire process from production to the
end consumer. EDUR-liquefied gas pumps are especially used to supply
LPG gases (liquefied petroleum gas) such as butane,
propane and their derivatives.
Variants of
EDUR-Liquefied Gas Pumps
Liquefied gas pumps are often considered as LPG pumps, LNG pumps, CO2 pumps
or tank truck pumps. EDUR-series for liquefied gas pumps include the series LB, NH and S. Through a modular
design, the pumps are available in a variety of construction styles and
materials such as spheroidal graphite iron or stainless steel as well as with different shaft seal
systems and drive solutions (explosion-protected motors or also hydraulic
drive).
As required, we deliver customer-specific configurations. Of course, we can
also provide certificates of all authorized classification societies and necessary test reports.
