DatasheetThe Druck PV411A is a high-quality, versatile hand pump that combines four functions into one compact unit: hydraulic pressure, pneumatic pressure, vacuum generation, and fine pressure control. Designed for both field and laboratory use, the PV411A replaces multiple conventional hand pumps and provides precision, efficiency, and convenience in a single tool.
Key Features
- Hydraulic pressure: Up to 10,000 psi (700 bar)
- Pneumatic pressure: Up to 600 psi (40 bar)
- Vacuum generation: Up to 28.5 inHg (−960 mbar)
- Fine pressure control: For both pneumatic and hydraulic applications
- Unique vacuum priming function: Removes trapped air in hydraulic mode
- High-pressure generation: Achieved effortlessly using the volume adjuster
- Pressure/vacuum selector valve: Includes integrated fine pressure relief
- Tamper-proof overpressure protection valve: Adjustable from 300 to 10,000 psi
- Removable hydraulic reservoir: Can be detached without fluid drainage
- Reservoir safety feature: Spring-loaded cap vents above 8 psi
- Hydraulic compatibility: Operates with distilled water or high-viscosity mineral oil
- 240° swivel head: Optimal viewing angle for reference gauges
- Low-friction PTFE-coated internal parts: Minimized wear and improved longevity
- Compact and ergonomic design: Lightweight and easy to operate with one hand
Typical Applications
- Calibration of pressure transmitters, indicators, and sensors
- Maintenance and troubleshooting of process pressure systems
- Field and laboratory use for hydraulic and pneumatic pressure generation
- Switch testing, leak testing, and pressure verification with reference devices
