Engineered to Endure
Crafted with proprietary chrome alloys (Available: High-chrome A05, Super-chrome A61, Ultra-chrome A14), the ELS pump resists wear from even the most abrasive slurries, including copper ore, frac sand, and acidic feeds. Its customizable material selection ensures optimal performance in specific wear and corrosion scenarios, while a hardness exceeding 60HRC guarantees extended service life in relentless conditions.
Innovations for Uninterrupted Performance
Advanced Solids Handling: Optimized through state-of-the-art solids modeling and finite element stress analysis, the ELS efficiently manages coarse solids and viscous slurries, minimizing blockages and downtime.
Double Mechanical Seal System: Sealed within an oil reservoir, this design prevents slurry ingress into the motor. Silicon carbide faces withstand submersion pressure, while minimal exposed wear areas extend seal life.
Anti-Cavitation Technology: Integrated winding thermostats monitor motor temperature, triggering alarms or shutdowns during overheating. Optional cooling jackets maintain safe operation in low-fluid conditions, ensuring continuous pumping.
Agitator Options: Two agitator configurations premix slurry to enhance solids concentration and pumping efficiency, ideal for thick slurries or settling sumps
Features That Drive Productivity
Clog-Free Design: An optional suction saver prevents blockages from tramp materials or oversized solids, critical for sump clean-up and thickener drain tasks.
Proactive Protection: Moisture detectors alert to fluid intrusion in real time, while temperature sensors guard against overheating.
Rapid Maintenance: T-bolt construction enables swift disassembly for inspections or part replacements, slashing downtime.
Tailored Solutions: Customize with high-chrome wear parts, agitators, cooling jackets, or suction savers to meet exact operational demands.
Powerful Excavators (Cutters) Available
Excavators
First Pump® offers powerful wear-resistant electric submersible excavators. These excavators can be attached to the submersible slurry pumps, enabling the formation of an autonomous excavation system for compacted soil. In such scenarios where compacted soil is involved, an earth-moving machine would typically be needed. By using these First Pump® excavators, there is a substantial increase in the average solid production of the dredging system.
Cutting Heads
The First Pump® cutters come equipped with wear-resistant teeth. These teeth feature the two-piece tooth system. This system serves multiple crucial functions. It guards against premature breakage, stops teeth from getting lost, and safeguards the integral locking system. As a result, it guarantees the uninterrupted operation of the pump.
Technical Details
Cutting Head: The cutting head is engineered in a way that the presence of interchangeable hard teeth helps in reducing the cost of wear parts.
Power Unit: It is furnished with a high-efficiency and long-lasting electric motor.
Depth Capability: Through the use of a steel cable suspension, these excavators are capable of operating at depths of up to 250 m.
First Pump® JET-RING: A Ring Integrated with High-Pressure Water Jets
The JET-RING is a ring featuring high - pressure water jets. This unique design enables it to be effectively utilized for operations on compact, extremely dry, or clayey materials. It can be paired with either electric or hydraulic pumps. Functioning in combination with other equipment or as a substitute for excavators, it offers great versatility.
The JET - RING comes equipped with the following components:
A ring frame that is attached to the pump filter.
A high - pressure centrifugal pump, which is accessible in both electric and hydraulic versions.
A suction pipe complete with a filter and a non - return valve.
A delivery line.
Performance Specifications
Flow Capacity: 10 to 2000 m³/h
Head Range: 8 to 80 m
Motor Power: 3 to 315 kW
Max Particle Size: 60 mm
Speed: 980 to1460 rpm
Materials: High-chrome alloy (High-chrome Alloy A05, Super-chrome A61, Ultra-chrome A14), cast iron, SS304, SS316L.
Selecting the Right Pump
Consider critical factors such as:
Particle Size (up to 60mm)
Flow Rate (m³/h) and Head (m) requirements

Our technical experts are available to guide you through model selection, ensuring optimal performance for your application.
Versatile Applications
The ELS Submersible Slurry Pump excels in aggressive environments across industries:
Mining, Mineral Processing & Quarrying: Ore Slurry, Tailings, Rocks, Sump clean-up, tailings management, red mud recovery.
Industrial Processing: Clarifier sludge, fly ash sumps, seawater/sand slurry transport.
Dredging & Waste Management: Sand, Gravel, Thickener drainage, corrosive slurry pumping, tailings recovery.
Coal washing & ash handling
Construction site dewatering
Ideal for Feed Materials:
Frac Sand | Mineral Concentrates | Pulp/Paper Slurries | Water with Heavy Solids
Why the ELS Pump Stands Out
Extended Wear Life: High-chrome alloys and smart design reduce replacement costs and downtime.
Adaptability: Handles variable fluid levels, abrasive feeds, and corrosive chemicals with ease.
Total Support: Backed by a full suite of mining hoses, slurry valves, pipes, and wear-resistant spare parts.
Engineered for Your Toughest Challenges
When failure is not an option, the First Pump® ELS Submersible Slurry Pump delivers relentless performance. Its robust construction, intelligent features, and customizable options ensure it thrives where others falter—keeping your operations running smoothly, even in the most punishing conditions.
