High-pressure pumps delivering up to 120 bar
When using a Zero Liquid Discharge (ZLD) or Minimal Liquid Discharge (MLD) system for treatment of industrial wastewater, a membrane-based process will help to reduce the energy consumption radically.
The membrane-based process, also known as reverse osmosis, requires membranes and a high-pressure pump that can operate with pressures up to 120 bar.
Membranes have been developed for pressures up to 120 bar and with Danfoss APP W HC pumps, professionals now also have access to a reliable and high-efficient pump that meets the requirements of the membrane-based process.
Features and benefits
World-class efficiency - up to 90% at all operation points
Low complexity with few moving parts
Easy to operate and maintain
The pump is oil-free to avoid contamination
Easy scalability when coupled in parallel
Made of first-class Duplex steel to prevent corrosion in aggressive environments
Save water, time and money with the new APP W HC pump
Reduce the discharge of industrial wastewater by applying the highly efficient Danfoss APP W HC pump with an outlet pressure of up to 120 bar.
High-pressure pumps delivering up to 90% efficiency
With efficiency rates up to 90% at all operating points, the Danfoss APP W HC pumps are designed to produce the highest level of efficiency in ZLD (zero liquid discharge) and MLD (minimal liquid discharge) applications. The strong and extremely robust pumps are made of non-corrosive materials and guarantee high reliability and low operational costs over the service life.
The pumps are positive displacement pumps with axial pistons that move a fixed amount of water in each cycle. Flow is proportional to the number of shaft revolutions (rpm). Unlike centrifugal pumps, the APP W HC pumps produce the same flow at a given speed no matter what the discharge pressure.
The simple pump design allows easy installation, inspection, and maintenance. Furthermore, the pump operates without oil to prevent contamination. The pumps can be parallel-coupled in trains to fulfill the required capacity at any time.
