Sulzer has announced the release of its new SIL pump range for industrial applications.
The range is designed for clean liquid processes, using Sulzer‘s long experience and in-depth pumping technology knowledge. It is ideal for pumping mainly clean and slightly contaminated liquids, viscous liquids up to 250cSt, and fibrous slurries up to a consistency of 1%.
The hydraulic design ensures efficient pumping with a low net positive suction head required (NPSHr) across the whole pump range.
The inline design together with the monoblock construction makes the SIL pump compact, rigid and reliable. The pump is available either with an integrated motor or with a standard International Electrotechnical Comittion (IEC) motor. SIL pumps are easy and fast to install both in vertical and in horizontal positions, and they require only a small installation space.
The SIL inline pump range fulfills the efficiency regulations across all industries, as well as the design requirements of the ISO 5199 international standard. For the customer this means substantial savings in the total life-cycle costs and a reduced environmental footprint.
The SIL pump exceeds the EU’s requirements for energy-related products (ErP). These regulations specify the minimum efficiency values for water pumps, with the target of reducing the energy consumption. The entire pump range exceeds the MEI 0.4 (Minimum Efficiency Index.
MEI, the minimum efficiency index for standardised water pumps, was set to be ≥0.4 as of the beginning of 2015. This means that at present 40% of the pumps on the market do not comply.
Sulzer’s SIL pump range fulfills the requirements of ErP and of all other industrial efficiency regulations.
The monoblock construction of the SIL pump range eliminates the need for a bearing unit. This solution minimises the number of wearing parts and the need for maintenance.
The optimised shaft sealing chamber and impeller balancing holes guarantee improved conditions for the shaft seal and maximise its life time.
The impeller is designed in tandem with the casing and sealing chamber. This design results in efficient hydraulics with reliable shaft sealing, ensuring high reliability. The closed impeller is designed to suit versatile liquids, maximizing standardization and minimizing the need for spare parts.
Minimised total cost of ownership (TCO)
The installation, operating, and spare part costs of the new SIL pump range are low, as are the downtime costs thanks to the minimised need for maintenance of the trouble-free monoblock construction. If needed, the back pull-out design allows quick access for servicing without detaching the pump from the piping.
Due to the high efficiency of the SIL pump range, its energy consumption is low. Together these qualities of the new SIL pump reduce the total cost of ownership to the benefit of the customer.
