DAYLIFF DSP 5‑12 PUMP C/W MOTOR, CONTROL BOX

Product Description

The Dayliff DSP 5‑12 Pump with motor and control box is a submersible multistage centrifugal borehole water pump engineered for clean water extraction from boreholes and wells in domestic, agricultural or light commercial applications. It is part of the Dayliff DSP 5 series that uses floating‑type Noryl impellers, glass‑filled polycarbonate diffusers and stainless‑steel chambers for strong sand handling capability and long service life. The pump is coupled to a sealed stainless‑steel motor and supplied with a separate control box that includes essential protective and operational components for reliable electrical connection and motor safeguarding.

Key Benefits and Features

• Multistage centrifugal design delivers dependable head and flow performance suited for borehole water supply into overhead tanks or pressure systems.
• Pump wet end components including Noryl floating impellers, glass‑filled polycarbonate diffusers and stainless‑steel chambers provide excellent sand handling and abrasion resistance for longer service life in clean water environments.
• Sealed two‑pole submersible motor in stainless‑steel construction supports continuous submerged operation with corrosion resistance and reliable performance.
• Separate control box simplifies electrical setup and incorporates an isolator, run indicator light, thermal overload protection and starting capacitor for safer operation. Auxiliary terminals allow connection of control devices such as float switches, pressure switches or probes.
• IP68 rated submersible enclosure and F‑class insulation support continuous operation in submerged conditions.
