The DAYLIFF DID pump range are of non-self-priming, high efficiency in-line centrifugal design with a special application for pumping highly mineralised water especially in RO plant application. The pumps are of heavy-duty construction and designed for continuous duty in high pressure installations. Material of construction is Duplex SS2205 for the inlet and outlet chamber, seal base, pump sleeve and shaft while impellers and chambers are of Stainless Steel 904L. Pumps are water lubricated and are provided with a standard cartridge type mechanical seal and BSP internally threaded counter flanges.
MOTOR
The pumps are coupled to high efficiency IE3 totally enclosed fan cooled 2-pole motor complying with IEC standards and must be connected to an effective motor starter in accordance with local regulations.
