Benefits of Thermoplastics in Water Management Equipment Highlighted by SABIC
SABIC, one of the world’s largest petrochemical manufacturers dealing with chemicals, polymers, performance chemicals, fertilizers, metals, and innovative plastics, attended the 2015 Aquatech tradeshow in Amsterdam. There, the chemicals company showcased the potential design, cost, and compliance benefits of replacing existing equipment with thermoplastic materials in water management and other systems.
Meeting safety regulations concerning low lead for drinking water applications can be extremely difficult, but it can easily be done with plastic equipment and systems. In addition, upcoming legislation is now demanding more energy-efficient pumping systems in relation to infrastructure, buildings, and transportation. Plastic is a lightweight alternative to metal. Therefore, it can increase energy efficiency in pump applications. This is a serious improvement, especially considering the fact that these types of pumping systems currently take up 10 percent of the total global electricity.
Plastic systems also offer a more cost-effective solution to traditional metal systems since they do not corrode. This has the added benefit of reduced maintenance requirements while offering a flexible pump design and improved surface finish for water management equipment.
For example, the Villagepump 500 is a patented, mechanical, portable water pump that can provide up to 500 liters of purified drinking water per hour. The pump has proven itself when used with surface rainwater and non-salted drinking water in communities throughout Africa and Asia.
The pump’s housing has also been considered when it comes to the design of thermoplastic pumps. The pump’s housing is made with SABIC’s GELOY resin. This detail provides corrosion and impact resistance, making it a good solution for outdoor applications. The valve unit is integrated and lightweight, because it is made out of glass fiber reinforced NORYL resin. This provides dimensional stability, chemical resistance, and high processability, making the products certified for safe potable water use throughout Europe and the United States.
