Dayliff DDA

The Dayliff DDA submersible multistage centrifugal pumps are designed for pumping clean, non-aggressive liquids in light-duty and domestic applications.
DDA submersible pumps are best for well and borehole water supply but are also ideal for irrigation, water transfer from tanks and pressure boosting needs.

Pump Construction

• Impellers – Polypropylene
• Diffusers – Polypropylene
• Pump Casing – Stainless Steel

Features of Dayliff DDA Pumps

Jacketed Motor Arrangement – provides excellent motor cooling and allows the pump to work mini-submerged.

Mechanical seals (twin on DDA600C & DDA1200C2) in an intermediate oil chamber for greater pump reliability.

Pressure controllers are ideal for automatic pump operation.

All pumps come with a  20 m cable.

DDA 1000p, DDA600C, and DDA1200C2 connections include a low-level float switch with an adjustment clamp and inbuilt capacitor for easier installation and suitability to well and tank applications.

DDA900C is particularly suited to borehole applications and includes an external control box that incorporates an isolator, run indicator light, thermal overload protection, and starting capacitor, which can be connected directly to mains power.

The box also includes auxiliary terminals that connect control probes, pressure switches, or float switches.

MOTOR

Enclosed and rewindable liquid-cooled, non-overloading induction motor designed for continuous operations incorporating a thermal cut-out in the windings to protect against overloading.

The pump motor connection to the mains power is directly through a 10 A fuse or miniature circuit breaker.
