PV411A – Four-in-One Pressure and Vacuum Hand Pump

The PV411A is a high quality field proven pressure and vacuum hand pump providing functionality never before seen in a hand held pressure source.

The PV411A replaces four conventional hand pumps and offers the following additional features that can be found in the datasheet.



  • Multi-function “4 In 1” handpump
  • Pneumatic pressures to 600 psi (40 bar)
  • Hydraulic pressures to 10,000 psi (700 bar)
  • Generates vacuum to -28.5 inHg
  • Vacuum priming for hydraulic systems
  • Excellent low pressure control
  • Adjustable overpressure protection


  • 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 lightweight design with comfortable hand grip
