EDUR Centrifugal Pumps for Liquefied Gases

EDUR centrifugal pumps play a central role in the production, transport, storage, and distribution of liquefied gases. In their liquefied state, gases can be stored and transported much more efficiently compared to their gaseous form. Liquefaction is achieved either by increasing pressure or lowering the temperature below the condensation point. When needed, the gas can be reverted to its gaseous state through controlled expansion, allowing pumps to supply the gas to end-users as required.

EDUR pumps are essential components in the entire liquefied gas supply chain. In the liquid state, gases exhibit a significantly higher energy density, simplifying transport and storage compared to gaseous form. Liquefaction is carried out by pressure increase or temperature reduction below the boiling point. Controlled expansion then converts the liquid back into gas, which is delivered to the customer using appropriately designed pump systems.

EDUR designs and manufactures centrifugal pumps specifically for liquefied gas applications in production processes, as well as for transportation, storage, and distribution. The pumps are engineered with high gas-handling capability, ensuring reliable performance even when pumping gas-laden liquids. Thanks to low NPSH (Net Positive Suction Head) requirements, EDUR pumps operate cavitation-free, providing dependable flow in both suction and feed operations.

EDUR liquefied gas pumps are available in ATEX-compliant designs. Various sealing systems—such as double mechanical seals or hermetically sealed magnetic couplings—guarantee high operational and system safety.
