Mine Paste Backfill Pump

Product Introduction

The ShangHe Mine Paste Backfill Pump is an industrial-grade giant, specifically engineered for the harshest underground mining and heavy civil engineering environments.

Unlike standard concrete pumps, this heavy-duty stationary system is designed to handle extreme-density materials, including paste, thickened tailings, fly ash, and cemented backfill mixtures. By pumping these materials back into underground mined-out voids, it provides critical ground support, minimizes surface tailings disposal, and creates a safer, more sustainable mining operation.

Core Components & Advantages

1. Massive Pumping Power:
   Driven by robust dual electric motors and a high-capacity hydraulic system, it generates extreme pumping pressure, capable of pushing high-viscosity paste over incredibly long horizontal and vertical distances deep underground.
2. Wear-Resistant Delivery Cylinders:
   Backfill materials are often highly abrasive. Our pump features enlarged, specially hardened delivery cylinders and heavy-duty S-tube valves designed to withstand extreme wear and tear, dramatically extending the maintenance cycle.
3. Continuous, High-Volume Output:
   Built for 24/7 industrial operations, the system delivers a massive and continuous output ranging from 40 to 150 cubic meters per hour, keeping up with the demanding pace of modern mine backfilling.
4. Rigid Skid-Mounted Structure:
   The entire pumping module is securely bolted onto a heavy-duty steel skid base. This stationary design eliminates unnecessary towing components, ensuring absolute stability during high-pressure pumping and allowing for permanent installation in backfill plants.
5. Advanced Control System:
   Equipped with a smart PLC control panel that precisely monitors hydraulic pressure, material flow, and motor temperature, ensuring safe and automated operation in complex mining environments.

Typical Applications

The ShangHe Paste Backfill Pump is the heart of underground material transport for:

• Underground Mine Backfilling: Filling mined-out stopes and voids with cemented paste or hydraulic fill to prevent ground collapse.
• Tailings Management: Pumping thickened mining waste back underground, reducing the need for surface tailings dams and environmental risks.
• Deep Tunnel Construction: Pumping large volumes of concrete or stabilizing mixtures for deep-shaft and long-distance tunnel lining.
• Industrial Sludge Pumping: Transporting high-concentration industrial sludge, coal ash, and viscous materials in power plants.
