Engineering company Danfoss announced in a press release that it is releasing a new series of APP pumps designed for Zero Liquid Discharge (ZLD) and Minimal Liquid Discharge (MLD) in a bid to enter the wastewater market.
Danfoss claims that the new pumps deliver total efficiency rates of 90% at pressures up to 120bar, as well as flow ranges from 11 to 24m3/hour.
According to the release, the APP W HC pumps have been built to fuel the growing demand for energy efficient ZLD and MLD solutions.
“For the last 15 years, our axial piston pumps have proved their efficiency in reverse osmosis desalination”, said Jesper Bentzen, Danfoss sales director.
“We have applied this know-how to match the demands of ZLD/MLD, where utilities and system builders are looking for high efficiency and robustness, relentless reliability and low operational costs.”
The firm alleges that the pumps are ‘easy’ to install, inspect and maintain. It also operates without oil to prevent contamination.
“No matter the water quality, the APP pumps instantly adjust to ensure constant flow and efficiency in the ZLD/MLD processes. The operation is extremely easy, since changes in pressure impact neither flow nor efficiency”, said Danfoss product manager Kevin Evald.
