High Pressure
High-Pressure Plunger Pump Solutions
General Pump high-pressure plunger pumps are designed and manufactured to pump water and other liquids of similar viscosity, assuming they are compatible with the pump’s construction materials. Durable by design, these plunger pumps are built to ISO 9008 standards and are ideal for a variety of intermittent or continuous-duty applications and water sandblasting.
Engineered for Extreme Duty
Industrial environments labelled “high pressure” mean more than just elevated PSI. These duties demand precision, longevity and reliability—whether the application is water-blasting, tank cleaning, surface preparation, mining, or water treatment. At General Pump, our plunger pumps are designed and manufactured to meet ISO 9008 quality standards and are ideal for both intermittent and continuous duty applications.
What Sets Our High‐Pressure Pumps Apart
- Quality construction — Built to ISO 9008 standards, with robust manifolds and precision components.
- Versatile duty profiles — Suitable for water-sandblasting as well as industrial cleaning, mining, and high-pressure rinse operations.
- Strong performance range — Our catalog lists pumps up to 22,000 PSI and flows up to 236 GPM (in certain series).
- Comprehensive product ecosystem — Not just pumps: accessories, nozzles, lance systems, unloaders and filtration are all available from one supplier.
Typical Applications
| Application | Challenge | How Our Pumps Handle It |
| Waterblasting / Surface Prep | Requires very high pressure, consistent output and abrasion from grit | Precision plunger design resists wear and delivers steady pressure |
| Tank & Vessel Cleaning | Complex geometry, confined spaces, mixed fluids | Flexible mounting and accessory compatibility ensure adaptability |
| Mining & Heavy Industrial Duty | Harsh environment, continuous operation, heavy solids | ISO-rated build, robust materials and maintenance guidance support long life |
| Industrial Rinse/Water Treatment | Variable flows, sometimes high temperature, chemical exposure | Pinpoint flow/pressure sizing and material options for chemical compatibility |
Key Design Considerations
- Inlet conditions & filtration: One of the most common causes of high-pressure pump failure is inadequate NPSH (Net Positive Suction Head) and dirty inlets. Correct inlet design and strainers significantly improve longevity.
- Seal and material compatibility: Choosing the right materials and seal types up front (for fluid chemistry, temperature and duty cycle) avoids early failure.
- Duty cycle alignment: Pumps built for intermittent high-pressure duty may fail under continuous operation. General Pump models are specified by duty and field conditions.
- Lubrication and maintenance schedule: Adhering to house-spec lubrication intervals and using correct oils matters far more than is often assumed.
High Pressure Plunger Pump FAQs
What defines a “high-pressure” pump?
At General Pump, the “High Pressure” category starts when typical working pressure exceeds 150 psi—but our industrial plunger pumps often operate at thousands of PSI.
What flow and pressure combinations are available?
Our catalog shows options up to 22,000 PSI and flows of 236 GPM or more depending on the series.
What industries use your high-pressure pumps?
Industries include water-blasting & surface prep, mining, industrial wash-down, tank/vessel cleaning, and any application needing reliable fluid handling at elevated pressure.
How do I pick the right pump for high-pressure duty?
You should assess: required pressure (PSI), required flow (GPM), fluid type and chemistry, duty cycle (intermittent vs continuous), and environment (abrasion, temperature, solids). Use our product literature and consult our application team.
What maintenance should I expect?
Initial break-in should be followed by scheduled oil and seal inspections, particularly in abrasive or continuous-duty settings. Proper upkeep is critical in extending service life.
What accessories are available for high-pressure setups?
General Pump offers accessories such as industrial nozzles, jetter valves, industrial regulating valves, flow switches, pulsation dampeners and filtration kits.
