Sterling-SIHI launches another multistage pump to reduce whole life cost.
The global search for renewable energy sources for power production has brought bio-mass high up the agenda. Their lower calorific values, compared with fossil-type fuels, often require an efficient steam cycle to operate at reduced temperatures and pressures less than 100bar.
Lately, Sterling-SIHI has complemented its SIHImulti range of premium efficiency multi-stage pumps with a sub-100bar unit that has a perfect fit with the Bio-mass power process. Unrivalled life-cycle cost was the goal of the SIHImulti design engineers when tasked with the development of the MSC multistage pump to complement the existing MSL (40bar), MSM (63bar), and MSH (160bar) families.
With permissible temperatures in the region of 180˚C, the range offers volumetric flowrate in excess of 220m3/hr. Importantly, the unit has purposely been designed for use with wide ranging Variable Speed Drives. In other words, the inner details of the pump will accommodate high and low flow rates with an equal degree of component reliability due to sufficient lubrication. [Page Break]
Continuing with the high quality profile of the SIHImulti range, the MSC (100 bar) also employs the highly regarded (and patented) method of balancing the rotating assembly. By eliminating the critically-tight clearances, which surround conventional balancing drums; SIHI has simply removed the problem of wear-induced efficiency loss that occurs over time.
“Our new Centurion, as we like to call it, is a product which has been designed to address a good number of long-standing market led demands – it really is designed for life. No stone has been unturned where mechanical, hydraulic, process, and sealing performance is concerned. The development priority was to produce a pump with benefits that are unrivalled in the long-term; along with those at the point of sale,” explains Shaun Hampson, of Sterling-SIHI.
Comparatively low NPSH requirement, of the SIHImulti product family, is another proud benefit of Sterling-SIHI. The end-suction configuration has, not only reduced the NPSH requirement for pumping products near to their boiling point, but also provides a basis for only one mechanical seal.
Meeting the technical requirements of ISO 5199 provides independent assurance that this modular product has the ability to help with reduced site inventory based on long-term reliability, while simplifying maintenance. [Page Break]
Amongst other available options, some of the pre-configured products include: Inter-stage discharge, that allows multiple pressures to be employed from a single pump; flow-harmonising suction branch in order to retain the impressive NPSH requirement while install as a top/side suction; and inclusive of a dummy stage in order to plan for future expansion.
Reliability, premium efficiency levels, and highly modern construction makes the entire SIHImulti family an ideal range of pumps for a wide spectrum of applications.
Along with the whole SIHImulti family, there are a broad range of digitally integrated devices that can be accommodated in stand-alone and DCS based operations. These range from bypass flow-control valves, through to condition based monitoring units, and variable frequency drives.
Liquid, gas, and vapour handling expertise underpins the unique ability of Sterling-SIHI to provide its clients with the optimum pumping system. Whether there is a requirement to process chemicals, create vacuum, generate energy, recover VOC emissions, or simply investigate life-cycle cost reduction, there is a team available with a reliable solution.
