DAYLIFF DSP 3‑11 PUMP C/W MOTOR, CONTROL BOX

Product Description

The Dayliff DSP 3‑11 Pump with motor and control box is a submersible multistage centrifugal borehole pump designed for dependable clean water delivery from wells and boreholes for domestic, agricultural and light commercial water supply. It is part of the Dayliff DSP 3 range of stainless‑steel multistage pumps that feature floating‑type impellers and glass‑filled polycarbonate diffusers for strong sand‑handling and abrasion resistance. The pump is connected to a sealed stainless‑steel submersible motor supplied with an external control box that includes thermal overload protection, isolator and run‑indicator features. The control box also provides auxiliary terminals to accept float switches, pressure switches or control probes for optional automation and enhanced protection. Multistage hydraulics support elevated water delivery into overhead tanks or pressure systems with reliable performance.

Key Benefits and Features

• Multistage centrifugal design delivers consistent head and flow suitable for borehole water extraction and supply applications.
• Pump wet end features floating Noryl impellers with glass‑filled polycarbonate diffusers and stainless‑steel chambers for strong sand handling and extended service life in clean water environments.
• Sealed stainless‑steel submersible motor supports continuous submerged use with corrosion resistance and long operational life.
• External control box simplifies installation and includes isolator, run indicator light, thermal overload protection and starting capacitor safeguarding the motor.
• Auxiliary terminals on the control box allow connection of level or pressure control devices (float switch, pressure switch or probes) for automation and advanced protection if needed.
• IP68 submersible rating ensures safe operation under fully submerged conditions.
