In response to the growing demand for energy efficient ZLD solutions, Danfoss now releases its first APP pumps targeted large capacity wastewater treatment plants.
"For the last 15 years, our axial piston pumps have proved their efficiency in reverse osmosis desalination. We have applied this know-how to match the demands of ZLD, where utilities and system builders are looking for high efficiency and robustness, relentless reliability and low operational costs", says Jesper Bentzen, Sales Director Danfoss. The new APP W HC pumps that handle flow ranges from 11 to 24 m3/hour are made of Duplex stainless steel to provide maximum corrosion protection.The ZLD APP pumps can be parallel-coupled to fulfill the required capacity at any time. If one of the pumps is out for maintenance, the remaining pumps automatically take over the full operation allowing the plant to run full speed around the clock.
The APP W HC pumps deliver a constant flow no matter amounts and quality of the wastewater. "No matter the water quality, the APP pumps instantly adjust to ensure constant flow and efficiency in the ZLD process. Operation is extremely easy, since changes in pressure impact neither flow nor efficiency", explains Kevin Evald, Product Manager. The simple pump design with few parts allows easy installation, inspection and maintenance. Furthermore, the pump operates without oil to prevent contamination.
