Atlas Copco WEDA D30N | Drainage Submersible Pump — Normal Head, 3 HP, 460V 3-Phase, 3" Discharge

Built to perform in tough conditions where standard pumps fail, the Atlas Copco WEDA D30N is a 3 HP (2.2 kW) drainage pump engineered to handle clean or lightly dirty water at water densities up to 68 lb/ft³, delivering up to 210 gpm at a maximum head of 85 ft. This Normal Head variant strikes the optimal balance between flow and lift, delivering up to 210 gpm at heads to 85 ft — the right choice when you need reliable all-round dewatering performance.

Performance at a Glance

The WEDA D30N is built around a 3,500 RPM high-speed design, with a 3" NPT discharge connection and a maximum solids-handling capability of 0.28". Whether you need to clear a flooded trench or maintain continuous dewatering on a long-term project, this pump delivers consistent, trouble-free performance on 460V Three-Phase power.

Technical Specifications

Key Features

• WEDA+ Protection System: Built-in rotation control, phase-failure protection, and thermal switches in every winding protect the motor automatically without external control panels
• Corrosion-Resistant Aluminum Alloy Body: Unique alloy provides the ideal combination of strength, light weight, and corrosion resistance for demanding site conditions
• Flexible Discharge Orientation: Discharge can be mounted vertically or horizontally to suit confined spaces or existing pipework layouts
• Modular Sealing System: Sealing configuration is matched to pump size to provide the optimal protection level for each application
• Class F Motor Insulation: Thermal switches in every winding guard against overheating; improved cable sealing prevents water ingress at the cable entry
• Adjustable Rubber Diffuser: Wear-resistant, adjustable diffuser maintains peak hydraulic efficiency over the service life of the pump
• Power Supply: 460V three-phase industrial power — requires 460V 3φ supply and appropriate motor protection.
• Safety Certification: Listed to CSA electrical safety standards for North American markets.

Built-In WEDA+ Motor Protection

Every WEDA D-series pump includes the WEDA+ protection system as standard: automatic rotation control prevents the pump from running in reverse after power interruptions; phase-failure protection shuts down the motor immediately if a phase is lost; and individual thermal switches in each motor winding provide independent overtemperature protection — all without requiring an external control panel.

Ideal Applications

• Construction site dewatering and groundwater removal
• Mine drainage and tunnel dewatering
• Flood emergency response and storm water management
• Municipal and industrial wastewater handling
• General all-round dewatering where balanced head and flow capacity are needed
