Atlas Copco WEDA S30N Submersible Sludge Pump

The Atlas Copco WEDA S30N handles thick, soft, wet mud and similarly viscous mixtures of liquids and solids. A vortex-type high-chrome impeller (55 HRC) clears large solids that would clog a standard drainage pump.

Key Features

• High-chrome cast-iron vortex impeller (55 HRC) for large solids passage
• Solids handling up to 2" — sludge and light slurry
• Built-in starter and motor protection — plug and pump
• Dry-running capability from a carefully sized, heat-dissipating motor
• Double mechanical seal in an oil bath with robust o-ring design
• External oil screws so preventive maintenance actually gets done
• Compact, high power-to-weight ratio for real transportability

Ideal Applications

• Sludge or light slurry
• Tank clean-out
• Trench and pond cleaning
• Mining and quarries
• Construction site dewatering

About the WEDA S30N

The Atlas Copco WEDA S30N pumps sludge and light slurry for tank clean-out and trench or pond cleaning. Its vortex-type impeller lets solids pass with the liquid, and the submersible layout puts the pump directly in the mixture being removed. Single-phase and three-phase versions offer different motor and hydraulic ratings, so the available supply determines which set of figures to use. The S30N provides a substantial increase in flow over the S08N, with a choice of configurations for jobs that need more sludge-handling capacity.

How the WEDA S30N compares

The S30N falls between the 1 HP WEDA S08N and the 7 HP WEDA S50N. Its single-phase version is 3 HP with limits of 230 gpm and 52 ft; the three-phase version is 4 HP with 250 gpm and 58 ft. The S50N reaches 370 gpm and 87 ft. Check the curve for your phase version in the WEDA pump range, because maximum flow and maximum head are not reached at the same time.

Questions about the WEDA S30N

Why does the WEDA S30N show 3 HP and 4 HP?

The single-phase version is rated at 3 HP, while the three-phase version is 4 HP. The 220–240V single-phase option is separate from the three-phase choices, so use the ratings for the configuration you select.

What size solids can it pass?

Both phase versions have a solids limit of up to 2 inches. Check the solids in the mixture against that limit before choosing the pump.

Does the phase change its weight or discharge?

Both versions weigh 56 lb and have a 3 inch discharge. Their motor and hydraulic ratings differ even though those installation figures are the same.
