Wanner supplies seal-less pumps for APATEQ water treatment systems

Wanner International has supplied three seal-less pumps to enable the production of effluent water with drinking water quality from a contaminated landfill site.

The company supplies the T100 ultra high-pressure reverse osmosis (RO) process pumps to APATEQ, which manufactures custom water treatment systems. APATEQ needed high-pressure pumps for part of its five RO stages for processing leachate at a landfill treatment plant in Sicily, Italy.

The contaminated water from the landfill site is converted to drinking water quality using APATEQ processes, which provides cost savings and environmental benefits by reducing the need for transport and treatment of leachate at an external facility on the mainland.

“We have decades of experience in the water and wastewater business and global industrial product manufacturing and commercialisation,” commented Ulrich Bäuerle, CTO at APATEQ. “Our corporate and technical teams are comprised of dedicated experts that aim for environmental protection and water conservation. As Hydra-Cell pumps have proven reliability, this provided the ideal solution for use with our smart water treatment systems.”

Paul Davis, managing director at Wanner, added: “We were delighted that the proven reliability of our Hydra-Cell RO pumps helped APATEQ to provide a complete solution to help reduce overall costs for their customer as well as being part of APATEQ’s innovate and pioneering water treatment systems to help tackle the ongoing waste problems and impact on the environment.”

Wanner’s Hydra-Cell pumps run up to 10m3 per hour at 120 bar at the two high-pressure RO systems and up to 15m3 per hour at 80 bar at the RO stage one.

The seal-less pump design reliably handles corrosive liquids, which eliminates unplanned downtime and reduces maintenance costs associated with replacing expensive seals and packaging. Moreover, the design ensures that the T100 can reliably handle liquids containing particles from 0.1 to 800 microns, and more abrasives with less wear than on axial piston or plunger pumps.
