The PV411A is a high-quality field proven pressure and vacuum hand pump providing functionality, which has never been seen before in a handheld pressure source.

This remarkable product replaces four conventional hand pumps and offers the following additional features:
- Hydraulic pressures to 10,000 psi
- Pneumatic pressures to 600 psi
- Vacuum to 28.5 inHg
- Low-pressure fine control
- Unique vacuum priming function removes trapped air during hydraulic operation
- High-pressure generation is accomplished with the volume adjuster, eliminating the physical effort associated with conventional hand pumps
- Pressure/Vacuum selector valve also provides exceptional fine control pressure relief in both pneumatic and hydraulic modes
- Tamper-proof adjustable overpressure protection valve which can be set to relieve pressures from 300 to 10,000 psi
- Removable hydraulic reservoir which can be disconnected from the pump without draining the fluid
- Reservoir safety feature with spring-loaded top cover vents if inadvertently pressurized above 8 psi
- Hydraulic mode designed to operate with distilled water and/or high viscosity mineral oil
- Highly sensitive volume adjuster is used for hydraulic, pneumatic, vacuum, and low-pressure operation
- Built-in stroke adjuster controls the pressure/vacuum generated per stroke
- 240° swivel head for optimum viewing of reference indicators
- Internal moving parts are PTFE anodized for reduced friction and wear
- Ergonomic, rugged, and light
