Atlas Copco WEDA L95N | Heavy Industrial Submersible Slurry Pump — 50 HP, 460V 3-Phase, 1,190 GPM, 4" ANSI

At 50 horsepower and 168 feet of head, the WEDA L95N is no longer a portable pump — it's a fixed or semi-fixed industrial asset engineered for years of continuous service in the most demanding slurry environments on the planet.

The Atlas Copco WEDA L95N sits in the upper industrial tier of Atlas Copco's slurry pump family. With 1,190 gpm of throughput at heads reaching 168 ft, a 4" ANSI flanged discharge, and the engineering DNA that's made the WEDA name standard issue at mines and quarries worldwide, the L95N is built for one job — moving abrasive, solids-laden water in conditions that destroy other pumps.

The Slurry Difference

Slurry pumps are not sludge pumps with bigger motors. The L-series uses a fundamentally different hydraulic design — semi-open multi-vane impeller, urethane-armored wear surfaces in the volute, and a hardened wear plate that's designed to be replaced as a wear part. Where a sludge pump prioritizes solids passage (open vortex geometry, 2" particles), the slurry L-series prioritizes survival under abrasion — pumping silica-laden water, dredging spoils, mineral process slurry, and quarry runoff for thousands of hours between rebuilds.

Specifications

Where the WEDA L95N Earns Its Keep

• Major mining operations — primary mill feed, deep pit sumps, long-distance tailings line pumping, underground deep dewatering
• Mineral processing at scale — flotation circuit slurry, thickener underflow, large-scale concentrate transfer
• Industrial dredging at scale — port and harbor maintenance, large reservoir and dam dredging, mining sediment ponds
• Phosphate, potash, and salt operations — high-volume slurry transfer through extended-life duty cycles
• Coal preparation — main refuse and tailings slurry pumping
• Oil sands — primary and intermediate bitumen slurry transfer
• Heavy power-plant duty — large ash transfer systems, bottom-ash sluicing

What's Different About a Slurry Pump's Hydraulic Path

Inside the volute of the WEDA L95N, every wetted surface is engineered for sacrificial wear and easy replacement:

• Hardened wear plate at the impeller inlet — replaceable as a single part, sized for the typical wear pattern of mineral slurries
• High-chrome cast-iron impeller — multi-vane semi-open design, 65 HRC hardness, profile optimized for solids up to 1.4"
• Polyurethane-armored volute liner providing 3–10x the abrasion life of bare cast iron at the same wall thickness
• Class F motor insulation — operating temperature margin that keeps the pump alive through dry-run, hot-water, and overload moments
• Double mechanical seal in a stainless cartridge running in an oil bath — same field-proven seal architecture as the rest of the WEDA family

Operating Profile

This is not a contractor's dewatering pump. The L95N is engineered for facilities that move slurry as a primary process — mine mills, large dredging operations, mineral processing plants. At 1,750 RPM, the L95N extracts maximum head per stage at sustainable wear rates, and runs cooler over continuous-duty cycles.

Service Footprint

Atlas Copco supports the WEDA L-series with a global parts inventory, rebuild kits matched to typical wear, and dealer-based field-service for major overhauls. Wear-part replacement at the typical service interval costs a small fraction of pump replacement, which is the whole reason slurry pumps are designed this way.
