Dayliff DSP 3 series is a range of multistage centrifugal borehole water pumping solutions engineered for high efficiency. These pumps are ideal for domestic, agricultural, and small-scale domestic water needs that require reliable and continuous flow.
Dayliff DSP 3 Pump Construction
Noryl impellers and glass-filled polycarbonate diffusers for excellent sand handling and wear resistance.
Stainless steel (AISI 304) inlet/outlet chambers, housing, shaft, and coupling for superior durability in corrosive underground environments.
Dayliff DSP 3 Features
- Multistage centrifugal design: Provides smooth flow and stable performance across varying depths.
- Floating impeller design: Enhances operational efficiency and allows handling of modest sand content.
- Sealed stainless steel motor: A liquid-cooled, 2-pole asynchronous squirrel-cage motor ensures reliable and cool operation even under heavy workloads
A single-phase motor is equipped with a separate control box that has an isolator, an indicator light, overload protection, and a start connector.
For three-phase motors, a DOL starter and Dayliff pump controller are ideal to ensure low-level protection, motor overload protection, and voltage fluctuation control.
