Product

Our Industrial High-Pressure Pump Series is engineered for demanding, continuous, high-intensity industrial applications. Whether you need cleaning, rust removal, surface preparation, pipeline pressure testing, or operation in other harsh environments, these pumps deliver consistent and reliable performance. All models feature a slow-speed design and are built with premium, high-quality components, including precision ceramic plungers, chrome-molybdenum alloy steel crankshafts, specialized high-polymer engineering plastic high-pressure seals, and wear-resistant rubber low-pressure seals. This ensures exceptional durability, lower noise levels, and superior volumetric efficiency.

Product Categories
  • Standard (SDB):
    Featuring a forged brass cylinder head, the SDB series offers an excellent price-to-performance ratio and is ideal for small to medium flow rates and extended operating times. The specialized, high-polymer, shape-memory, high-pressure packing and wear-resistant rubber low-pressure seals ensure a longer service life.
  • Corrosion-Resistant (SDC, MDC, DC):
    Constructed with SS316 stainless steel cylinder heads, this series provides superior corrosion resistance, making them suitable for various water qualities. All models use specialized high-polymer engineering plastic high-pressure seals and wear-resistant rubber low-pressure seals to guarantee the lifespan.
    • SDC: Ideal for small to medium flow rates and extended operating times.
    • MDC: Suitable for medium to large flow rates and 24-hour continuous operation.
    • DC: Designed for large flow rates and 24-hour continuous operation.
  • Durable & Economical (DA):
    Featuring a ductile cast iron cylinder head, the DA series provides a cost-effective solution for general water quality, large flow rates, and 24-hour continuous operation. The specialized high-polymer engineering plastic high-pressure seals and wear-resistant rubber low-pressure packing are the keys to its long operation life.
  • High-Pressure (HMDC, HDC):
    Built with solid-block SS316 stainless steel cylinder heads, this series delivers operating pressures above 250 bar, making them perfect for medium/medium-large flow rates and 24-hour continuous high-pressure operation. Both use specialized high-polymer engineering plastic high-pressure seals and wear-resistant rubber low-pressure seals, as the fundamental guarantee for longevity under demanding operating conditions.
    • HMDC: Medium flow rates.
    • HDC: Medium-large flow rates.
Applications
  • Industrial Process Cleaning & Cooling: Efficiently removes burrs and provides part cleaning and cooling.
  • Pipeline Pressure Testing: Conduct pressure tests to ensure the safety of pipeline systems.
  • Wet Sandblasting: Combines with sandblasting technology for more powerful surface preparation.
  • Condenser Tube Cleaning: Removes scale and fouling from condenser tubes, improving equipment efficiency.
  • Construction Equipment Cleaning: Cleans heavy equipment such as earthmovers, compactors, and more, removing surface debris.
  • Industrial Tank & Container Cleaning: Cleans tanks, bags, and other containers to prevent residue buildup and maintain a clean production environment.
  • Moss & Mold Removal: Effectively removes moss and mold from walls, floors, and other surfaces.
  • Sewer & Drain Cleaning: Provides powerful flushing to clear blockages in sewers and drains.
  • Paint Removal: High-pressure water effectively removes old paint.
  • Bark Removal: High-pressure water jet can efficiently remove bark.

HMDC-Industrial High Pressure Pump

HMDC series is low RPM professional pumps designed on base of MDC series for long consecutive operation, and medium flow rate higher pressure application. The manifold is cut from corrosion resistant SS316 block. The plungers are smaller in diameter to generate more than 250 bar of working pressure. This series is constructed with enhanced components to withstand 24-7 consecutive operation and shares most of the same components with MDC series.

HDC-Industrial High Pressure Pump

HDC series is low RPM professional pumps designed on base of DC series for long consecutive operation and medium to large flow rate applications. The manifold is cut from corrosion resistant SS316 block. The plunger has relatively smaller diameter to generate more than 250 bar of working pressure. This series is constructed with enhanced components to withstand 24-7 consecutive operation and shares most of the same components with DC series.
