2 Designed to perform Effi cient LPG pumps SIHI pumps and installations for liquefi ed gasses that comply with the highest demands Not only do Liquefi ed gases vary in terms of their industrial and domestic uses, but also the way in which they are produced. Liquefi ed Gasses, as defi ned by DIN51622, include media such as propane, butane, and their derivates. However, liquefi ed gasses also include others such as carbon-dioxide, ammonia, and other refrigerant-based components. During the various stages of distribution, pumps are required to transfer LPG in order to compensate for the pressure losses in the flow process. Under normal atmospheric conditions, liquified gases would be gaseous. Depending on the temperature at certain pressures, they can be liquefied. Industrial fuel depot Storage, transportation, and pumping of such Liquefied Gasses present the key success factors to handling this media. It is vital that the difference between this set of fl uids, when compared to conventional media, is fully understood when specifying equipment. In simple terms, an explosive liquid being pumped at its boiling point needs to be handled with greater care than a less complex liquid far away from its vapour pressure. Producer Rail tanker Bulk storage tank Road tanker Distribution point Consumer Oil burners, Filling stations etc. Regarding the pumping equipment, there is a set of criteria that the user or specifi er ought to consider as fundamental to the long-term trouble-free operation and ownership. Primarily, the most crucial point pivots around the vapour pressure of the liquefi ed gas. Key design features of SIHI LPG pumps + Low NPSH + High pressure generation + Steep pressure-to-flow curve + Gas handling + Easy handling + Safe and Easy operation + Easy maintenance + Safe working in Explosion Proof environment + Comply with the world standards of explosion proof design LPG Car filling solutions LPG Bottle filling solutions = Pump AutoGas dispenser While liquified gasses have unique fluid characteristics, they are best pumped with equipment that is designed specifically for their application. Conventionally, such liquified gasses require a flooded suction in which to give adequate NPSH, and therefore avoid problems.

SM-X submersible pumps The new Submersible SIHI pump combines the highly new renowned side channel technology and the all the benefi ts of a canned motor. The pumps are designed to operate under the most severe conditions without any possible risks. The canned motor of the submersible SIHI eliminates all maintenance and possible leakage. PC-X side channel pumps The PC-X is new generation of LPG pumps offering a wide range of benefi ts for the OEM and Fuel station. Combining the side channel with an intelligent drive, we have eliminated all possible risk of leaking, misalignment and diffi culties during start-up.

Combining the side channel with an intelligent drive, we have eliminated all possible risk of leaking, misalignment and diffi culties during start-up. UEA Multistage pumps with a special set of low NPSH centrifugal impellers, integrated with a single gas handling and priming stage, are used for high-flow applications. With flooded suction, these units are typically used for tanker (off) loading, transfer, and bulk storage. The UEA incorporates a priming stage (integral side channel stage) which prevents vapour locking and facilitates self-priming of the pump. PC-X, CEH Side channel pumps with a special low NPSH centrifugal impeller stage have self-priming characteristics in which to accommodate entrained with ease.

With our new technology of side channel pump combined with the new electronic drive, we have eliminated all possible risk of leaking, misalignment and difficulties during start-up. The new pump controls itself and is able to fill up 4 cars simultaneously at the lowest absorbed power possible. Beside this energy friendly pump design, all possible safeties are integrated to guarantee a safe and secure operation in all climate conditions. The complete design is Atex approved. The new SIHI SM-X is a submersible pump, using the highly renowned side channel technology, combining all the features and benefits of a normal side channel pump. The submersible pump features a canned motor design which means no maintenance and possible leakage. The SM-X can deliver LPG up to two dispenser and operates at 50 and 60 cycle network.

5 CEH and SC side channel pumps CEB vertical tank and UEA multi-stage pumps CEH The most common design of combination pump is of horizontal construction with ring-section multi-stages constructed with an inline axial suction branch for reduced entry losses. An oversized centrifugal impeller is mounted immediately downstream of a flow-harmonising, extended suction branch. Essentially, the flowharmonising suction branch, together with oversized centrifugal impeller, gives the low NPSH requirement while extending the hydraulic efficiency. The latter, downstream side-channel stage(s) give the vapour, gas, and mixed flow capability along with a high discharge pressure. Moreover, the side-channel design is inherently a self-priming design. Compared with other types of pump technology, the Side-channel Combination pump offers the user incredibly low suction inlet conditions. NPSH requirements of only 0.15m can be seen from some pump ranges for flow-rates up to 35 m 3 /hr. Primarily, this results in a simplified installation where costs are optimised. The need to excavate the pump foundation, or increase the vessel height is removed. While the side channel stages are oriented in-line with the initial centrifugal stage, this construction ensures that flow is not interrupted or reduced with partial vaporisation. SC SIHI SC pumps have the same features and benefits as the CEH pumps. These pumps are specially designed for auto gas stations. The SC pumps are very reliable and quiet. CEB Storage tanks with diameters that, generally, do not exceed 6 m, can be fitted with vertical tank pumps that have an externally mounted motor. Quite obviously, these pumps are mounted on the top flange of the tank with the hydraulic end submerged within the liquid. The orientation is very similar to the Side-Channel combination pump mounted vertically. The flow-harmonising hydraulic suction and oversized centrifugal impeller is positioned nearest to the bottom of the inner tank by means of an extension tube. The benefit of this configuration centres upon the hydraulic being in a flooded suction condition. UEA In order to facilitate higher flow rates of liquefied gasses, in the region of 200 m 3 /hr, more multi-stage centrifugal stages can be added. When the balance of stages becomes weighted to a greater number of centrifugal-type impellers, this is known as a Centrifugal Combination Pump. Centrifugal combination pumps continue to employ the benefits of the side-channel stage, which is mounted downstream of the other impellers towards the discharge. Consequently, large flows can be pumped very efficiently with the added benefit of self-priming, and gas/vapour handling. This pump design features the same design of flow-harmonising axial inlet, and specially developed first (low) NPSH stage.
