Understanding Haskel Pumps in High-Pressure Systems
Haskel pumps are industry-leading air-driven, high-pressure liquid and gas pumps known for their reliability in demanding applications. These rugged, maintenance-free pumps utilize intensifier technology to generate extreme pressures up to 100,000 psi (6,900 bar) with precise control. From hydrogen fueling stations to oil & gas, aerospace, and military applications, Haskel pumps provide safe, efficient pressure intensification where conventional pumps cannot operate. This guide covers Haskel pump principles, configurations, performance characteristics, and specialized applications.
Haskel Pump Key Specifications
Proper Haskel pump selection requires understanding these critical parameters for high-pressure applications.
| Specification | Description | Considerations |
|---|---|---|
| Max Output Pressure | 10,000 to 100,000 psi (690 to 6,900 bar) | Determined by intensifier ratio and air supply |
| Air Drive Pressure | Standard: 80-150 psi (5.5-10.3 bar) | Higher air pressure increases flow rates |
| Flow Capacity | 0.1 to 10 GPM (0.4 to 38 LPM) | Varies by model and pressure differential |
| Intensifier Ratio | 20:1 to 1000:1 common | Higher ratios achieve greater output pressures |
| Fluid Compatibility | Hydraulic oils, water, fuels, specialty gases | Materials vary by fluid (Inconel, 316SS, etc.) |
| Temperature Range | -65°F to 300°F (-54°C to 149°C) | Special configurations available for extremes |
| Safety Features | Pressure relief, exhaust mufflers, burst discs | Critical for high-pressure operation |
| Certifications | ATEX, PED, ASME, CE, CRN | Required for hazardous area installations |
Haskel Pump Installation & Maintenance
Proper installation and minimal maintenance ensure Haskel pumps deliver decades of reliable high-pressure service.
Air Supply Preparation
Clean, dry air is critical for reliable operation.
- Requirement: 40μm filtration, air lubricator
- Tip: Maintain 80-150 psi (5.5-10.3 bar) supply pressure
Inlet Filtration
Protect pump from particulate contamination.
- Critical: 10μm absolute filtration minimum
- Solution: Install duplex filter systems for continuous operation
Fluid Conditioning
Proper fluid treatment extends service life.
- Warning: Degassed fluids required for gas boosters
- Solution: Use Haskel-recommended fluids and additives
Preventive Maintenance
Minimal but critical maintenance requirements.
- Schedule: Annual inspection for continuous service
- Check: Air valve operation, seal condition, check valves
Pressure Relief
Essential system safety components.
- Requirement: Set below maximum rated pressure
- Safety: Install downstream of pump discharge
Rebuild Kits
Restore original performance when needed.
- Includes: Seals, valves, wear components
- Note: Factory-trained technicians recommended
