One of the primary features of this side-channel type of pump is the special suction impeller that requires extremely low levels of NSH. CEB pumps have been specifically designed for use with Liquefied etroleum Gas and other liquefied gases. DESIGN Sterling-SIHI side channel units are a low noise design of combination pump. They are ideal for pumping liquids that are stored at their boiling point, have a degree of entrained gas, or very low NSH conditions. The vertical tank pump has been designed in order to enable retro-fitting into most common tanks. Moreover, the dimensions are such that the unit can be used to replace submersible designs of pump. Although the pump can be supplied in other lengths, the standard size is between. -&. m.

Auto Gas Auto gas pump solutions: For auto gas station Sterling SIHI can offer thee different solutions:. Bottom-off loading, tank above surface of the earth, pump below tank, SC, CEH.. Top-off loading, underground tank with C unit above surface of the earth. Top-off loading, underground tank with internal tank pump, motor outside of the tank, CEB CEB C-unit SC, CEH Generally to select a pump two things has to be considered : Max start pressure during start phase : app: 7 9 bar Filling pressure during filling : app: bar Flow rate during filling : to l/min The filling pressure is depending of the smallest nozzle orifice diameter and car tank construction. In hot season periods is a short start pressure of 7 to 9 bar requierd, to calculate the flow rate a lower filling pressure of to bar is to consider.

Auto gas Underground tanks to dispenser C /7 -. 7/7 CEBA - Suction lift operation for under ground tanks Safety regulations, relating to minimum safe distances, coupled to a physical lack of site space require the installation of under-ground LG tanks. Discharge is therefore only possible via the top flange. The Sterling C plant and CEBA tank pump is a top mounted pump system. The hole C system or only the motor for the CEBA is located outside of the tank. The primary benefit being that there is no maintainable items such as electric motor or mechanical seals within the sealed & pressurised LG vessel. The CEBA is equipped with sealles magnetic coupling, free of maintenance. Auto gas station with C -system Auto gas station with CEBA Requested sizes: Motor.

Bottle filling Calculation of pump size CEHA / / UEAA C /7 7/7 Generally : The nominal output rating can be found in the capacity curve of a filling carrousel for LG cylinders. This nominal output rating, with regard to a constant filling pressure, should be increased by an additional, by-pass quantity led back to the feeling tank via a pressure sustaining valve. The additional quantity is normally from to %, depending on the size of the filling system. The differential pressure to be generated by the pump depends on the frictional characteristics (system curve) of the LG plant and the flow rate. Whilst the static head may often be neglected, the flow losses (dynamic head) of the components in the system can be calculated accurately with the aid of standard tables and empirical values.uncertainty often arises when calculating the system head, which in LG plants results mainly from pressure differences are highly dependent upon temperature changes. The seasonal temperature changes and thus the change in the pressure differential must also be considered especially at the discharge side. The pressure difference can be determined by means of the vapour pressure curve for the media being pumped. The use of the pressure gradient of the liquefied gas could also been used. This pressure gradient indicates the pressure change per C and guarantees a fast and accurate calculation of the differential pressure during the design stage. However it must be realized that, if extreme factors are taken into consideration, the resultant selection will be an oversized pump.thus the high cost of both the pump and the operation under the partial load, will produce an uneconomic solution and unfavourable operating conditions. ump selection: Cylinder :, kg Cylinder per hour : 7 / h Density :, kg/l estimated Flow : (, kg /, kg/l) 7 /h =. l/h =, m/h For carousel is a constant by pass flow of to % recommend to compensate pressure fluctuations and pump wear.

LG Transfer Selection of pump size CEHA / / UEAA Rating and aspects of installation : umps can be selected in accordance with the characteristic curves. Specific data, especially with regard to the required motor, will be given in our quotation. When selecting a pump size, it must always be borne in mind that vapour-free inflow can not always be guaranteed. In practice, it is always very important to design an installation in accordance with the state of the art (e.g. see installation drawing below) in order to minimalize vaporisation and headlosses. If not, some safety factors need to be incorporated in the determination of the pump design. Aspects on installation (general). The suction pipes must be configured such that there is a minimum of resistance. There should be no filters etc. which could impact high frictional loses and hinder the flow to the pump.. The minimum liquid tank level must consider flow resistance of the suction pipe the required NSH of the pump.. Bypass pipes from discharge side to inlet or suction side are not allowed. The bypass backflow from the relief valve must be fed back to the storage tank.. If one pump has to fill several tanks with different LG mixtures at different vapour pressures, efficient nonreturn valves or other suitable shut-off devices are required at the discharge side to avoid any service liquid blowing out during the change-over process.. Required differential pressure minimum: bar if a vapour return line is connected between tanks. - bar if no vapour return line is installed. More than bar in special cases, high temperature difference, high pipe resistant etc... If more than one pump are connected with one tank a special header with right dimensions can distribute the fluid free of vapour.
