LNG & LCNG
ACD’s complete range of pumps for LNG and LCNG applications include the seal-less TC34 and AC32 series of submerged motor centrifugal pumps as well as the P2K30 and X9SG high pressure reciprocating pumps. A special version of the hydraulic driven TOP 260 or 215 pumps with a cartridge shaft seal is available for safely unloading LNG trailers.
The compact, seal-less “canned” submerged motor pumps are designed for long life with zero-leakage. They are used for re-fuelling busses or trucks running on LNG, for off-loading trailers and for transferring LNG from one tank to another. All motors used for the seal-less pumps are variable speed type. The motor and bearings are cooled by the pumped cold liquid. The TC34 is supplied with a vacuum jacketed suction pot.
The submerged motor pumps often require to be driven at higher speed by
means of a Frequency Converter. However, Frequency Converter's need to be
ventilated and the hazardous zone classification restrictions means that
these Frequency Converter's need to be located in a 'safe area'. For road
tankers this is not possible, however, we can overcome this problem by
offering our hydraulically driven range of pumps to meet your road tanker
requirements when confronted by this particular problem
For filling high pressure LCNG cylinders or buffer storage we offer the explosion proof execution of the vertical P2K30 with suction sump as well as the high capacity modular (up to 3 cylinders operating in parallel) X9SG series with vacuum jacketed “cold ends”.
