Danfoss APP pumps are particularly well-suited for such RO treatments. Due to their unparalleled efficiency rates of up to 92%, they reduce OPEX and emissions significantly compared to other high-pressure pump technologies. Moreover, this efficiency remains the same regardless of varying pressure rates up to 120 bar, and operators can depend on their field-proven history of simple maintenance and long service intervals. The new APP pumps with ceramics makes the Danfoss portfolio of reliable, energy efficient high-pressure pumps for wastewater treatment ideal for even more use cases. Monitoring system available for all APP pumps with ceramics.
