Description
The Druck PV411A is a versatile hybrid four-in-one hand pump designed for pressure generation, vacuum generation and calibration of pressure instruments in field, laboratory and workshop applications. Combining pneumatic, hydraulic, vacuum and fine pressure control in a single portable unit, it eliminates the need for multiple hand pumps and simplifies pressure calibration tasks.
The PV411A generates pneumatic pressure up to 60 bar (900 psi), hydraulic pressure up to 700 bar (10,000 psi) and vacuum to -0.95 bar (-28.5 inHg). Its unique vacuum priming function removes trapped air from hydraulic systems, while the precision volume adjuster provides effortless high-pressure generation and exceptionally fine pressure control.
Designed with a pressure/vacuum selector valve, adjustable overpressure protection, removable hydraulic reservoir and 240° swivel head, the PV411A offers outstanding ease of use and operator safety. Its rugged, lightweight construction makes it ideal for calibrating pressure gauges, transmitters, switches, indicators, recorders and other pressure instruments.
