Product Description

The Dayliff DDA 900C is a submersible multistage centrifugal pump engineered for pumping clean, chemically non‑aggressive water in borehole and shallow well applications. It’s part of the DDA series of pumps that are suitable for water transfer from tanks, irrigation and pressure boosting as an alternative to conventional dry‑mounted pumps. The design features a jacketed motor for excellent cooling during semi‑submerged operation and comes with an external control box that integrates key safety and control features to make installation simpler and more reliable.

Key Benefits and Features

• External control box includes isolator, run indicator light, thermal overload protection and starting capacitor for direct mains connection
• Auxiliary terminals in control box for optional pressure switch, float switch or control probes
• Jacketed motor arrangement allows excellent cooling and continuous duty performance when semi‑submerged
• Single mechanical seal in an intermediate oil chamber improves reliability and prevents leakage
• Polypropylene impellers and diffusers with stainless steel pump casing for corrosion resistance and durability
• Supplied complete with 20 m power cable for convenient installation depth without extra cable purchasing
• Designed for clean water applications — not for solids or abrasive fluids
