The DAYLIFF DI/DIN pump range are of non self priming vertical multistage in-line centrifugal design suitable for a wide range of water supply, irrigation, liquid transfer and boosting applications. The pumps are of heavy duty construction and designed for continuous duty in commercial and industrial installations. All DIN pumps feature AISI 316 stainless steel vital components in contact with water including the impellers, intermediate chambers, shaft and top and bottom housings and are suitable for pumping highly mineralised corrosive water. DI pumps feature cast iron top and bottom housing and other components are AISI 304 stainless steel. All pumps are water lubricated and are provided with a standard cartridge type mechanical seal. They are supplied complete with BSP internally threaded counter flanges.
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.
