You understand the value of equipment that works as hard as you do, and with Yamada Pump products, you get a powerhouse combination of versatility, safety, and durability. You’ll find their pumps used not only in mineral extraction and slurry handling but also in reagent dosing, fuel and oil transfer, and even ventilation water control.

So, whether you’re managing thick slurry from a tailings pond, pumping high-viscosity lubricants to your crushers, or keeping your tunnels dry and clear, Yamada delivers pumps that perform day in and day out. If you're in mining, you can’t afford to gamble on equipment that might not stand up to the conditions—but with Yamada, you know you’re choosing a solution engineered for the extremes.

Mining Diaphragm Pumps: Yamada Pumps make it safe and efficient.

  • 1. Choose the Right Pump Series for Harsh Conditions
    You’ll want to start with the NDP Series – it’s engineered for the brutal, abrasive conditions in mining. Whether it’s slurries, solids, or chemical waste, this series is your workhorse underground or above.
  • 2. Go with Aluminum or Stainless Steel for Durability
    Don’t skimp on materials. Choose aluminum for lightweight and general use, or 316 stainless steel when dealing with corrosive sludges or chemicals. Trust us—longevity depends on it.
  • 3. Use Santoprene or Hytrel Diaphragms for Abrasives
    If your fluids have grit or small solids, you need diaphragms that can take a beating. Santoprene or Hytrel options give you the abrasion resistance to reduce downtime.
  • 4. Size the Pump Based on Flow Rate and Head
    You can’t just guess this part. Use the pump curves to match your required GPM (gallons per minute) and head height. Oversizing wastes air, and undersizing kills performance.
  • 5. Equip with a Leak Detection System
    To protect against diaphragm failure, add a leak detection system. You’ll be alerted early and avoid costly environmental spills or equipment damage.
  • 6. Use the Built-In Air Valve System to Prevent Stalling
    Yamada’s non-lubricated air valve design eliminates stalling—a lifesaver in remote mines where maintenance isn’t always fast. Keep air flowing, keep pumping.
  • 7. Optimize Air Pressure Settings
    Set your air pressure between 20–100 PSI, depending on your pump size and load. You’ll want to find the sweet spot where efficiency and performance meet.
  • 8. Install a Muffler or Silencer for Safe Operation
    Mining is loud enough. Reduce noise and protect your crew’s hearing by installing a muffler on the pump’s exhaust. It’s a simple addition with big impact.
  • 9. Use Flexible Connections for Vibration Control
    Pumps in mining shake, rattle, and roll. Use flexible hoses or connections to absorb movement and prevent damage to your lines or pump housing.
  • 10. Perform Regular Preventative Maintenance
    Don’t wait for failure. Schedule checks on seals, diaphragms, valves, and air lines. A little routine attention saves you major repair costs later on.

Yamada Mining Diaphragm Pumps offers several advantages, including:

  • Chemical Compatibility

    Yamada diaphragm pumps are built to handle a variety of chemicals, including antifreeze (ethylene glycol or propylene glycol). They can be made from materials like Santoprene, Viton, or Teflon, which resist chemical corrosion.

  • Self-Priming

    These pumps can run dry and self-prime from significant suction heights, making them ideal for transferring antifreeze from drums, containers, or reservoirs.

  • No Seal Leaks

    Since Yamada diaphragm pumps use a flexible Yamada diaphragm rather than rotating seals, they eliminate issues with seal wear and leaks, which are common in other pump types handling antifreeze.

  • Handles Viscosity Variations

    Antifreeze can vary in viscosity depending on temperature. Yamada diaphragm pumps can handle thicker fluids better than centrifugal pumps.

  • Variable Flow & Pressure Control

    Most Yamada diaphragm pumps allow easy flow rate adjustments without complex control mechanisms, making them ideal for metering antifreeze in different applications.
