The DAYLIFF DSP range of submersible multistage centrifugal pumps are specially designed for borehole supply applications. Material of construction include noryl impellers, glass filled polycarbonate diffusers, stainless steel inlet and outlet chambers, stage casings, shaft and pump housing. These quality materials together with the floating type impeller design provide the pumps with efficient performance ,excellent sand handling capabilities and long life. DSP 8-51 is engineered to meet industrial standards of MEI ≥ 0.4 and designed with an independent floating impeller mechanism.
MOTOR
The pump is coupled to a two pole sealed motor constructed principally from stainless steel. Single phase motors are supplied with purpose design Dayliff SCM control boxes for operation and protection against overload dry running and over/under volatge Three phase motors require a remote DOL starter; DAYLIFF SCT electronic pump controllers is recommended for comprehensive pump control including wireless low level protection, motor overload and voltage fluctuation.
