The five-plunger high-pressure pump is a robust and efficient positive displacement pump designed to deliver ultra-high-pressure fluid flow with minimal pulsation and exceptional stability. Its unique quintuple-plunger configuration ensures smoother discharge compared to single or triplex plunger pumps, making it ideal for demanding industrial applications requiring consistent pressure and flow rates.
Design and Working Principle
1.Plunger Mechanism:
Features five axially aligned plungers driven by a crankshaft or cam system, phased at 72° intervals to ensure overlapping discharge cycles.
This design reduces pressure fluctuations (pulsation) by ~90% compared to triplex pumps, enhancing system longevity.
Materials:
Plungers: Hardened stainless steel or ceramic-coated for wear resistance.
Seals: Advanced polymer or reinforced elastomers compatible with harsh fluids (e.g., water, chemicals, fuels).
2.Pressure and Flow:
Operates at pressures up to 3,000 bar (43,500 psi) with flow rates scalable by plunger diameter/stroke.
Typical flow range: 10–500 L/min (depending on model).
Key Advantages
Low Pulsation: Even fluid delivery minimizes vibration, reducing stress on downstream components.
High Efficiency: Optimized volumetric efficiency (>95%) due to precision machining and minimal slip.
Durability: Robust construction for 24/7 operation in abrasive or corrosive environments.
Versatility: Configurable for waterjet cutting, hydraulic testing, descaling, oil & gas, and chemical injection.
Applications
Waterjet Cutting: Delivers ultra-high-pressure water for precision machining.
Industrial Cleaning: Hydroblast systems for surface preparation.
Oil & Gas: Well stimulation, pipeline hydrotesting.
Power Generation: Boiler feed pumps, descaling in steel plants.
The five-plunger high-pressure pump combines advanced engineering with reliability, offering superior performance for critical high-pressure applications. Its low-maintenance design and pulsation damping make it a preferred choice across industries.
