Designed to performSIHI® pumps and installations for liquefied gasses that comply with the highest demands.

Not only do Liquefied gases vary in terms of their industrial and domestic uses, but also the way in which they are produced. Liquefied Gasses, as defined by DIN 51622, include media such as propane, butane, and their derivates. However, liquefied gasses also include others such as carbon-dioxide, ammonia, and other refrigerant-based components.

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 fluids, 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.

Regarding the pumping equipment, there is a set of criteria that the user or specifier 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 liquefied 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

Solutions for LPG transfer and bottle filling

UEAMultistage 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.

CEHSide channel pumps with a special low NPSH centrifugal impeller stage have self-priming characteristics in which to accommodate entrained with ease.

CEH and SC side channel pumps

CEHThe 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 flow-harmonising 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 0.15 m (0.49 ft) can be seen from some pump ranges for flow-rates up to 35 m3/h (154 US gpm).

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.

A design with hydrolic motor is especially designed for truck offloading.

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 vertical tank and UEA multi-stage pumps

CEBStorage tanks with diameters that, generally, do not exceed 6 m (19.7 ft), 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.

Technical data CEB UEA

UEAIn order to facilitate higher flow rates of liquefied gasses, in the region of 200 m3/h (880 US gpm), 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.

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.

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.
