• Hydraulic pressures to 10,000 psi
• Pneumatic pressures to 600 psi
• Vacuum pressures to 28.5 inHg
• InH2O range pressure generation

High quality and field proven, the Druck PV411A pressure and vacuum hand pump provides functionality never before seen in a handheld pressure source. The remarkable PV411A hand pump replaces four conventional hand pumps – hydraulic, pneumatic, vacuum, and low pressure operation.

The PV411A four-in-one hand pump is designed for hydraulic operation with distilled water (no alcohol) and mineral oil equal to 40 wt. For combined hydraulic and pneumatic optations, it is recommended to use distilled water during hydraulic operation.

• 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
• The tamper proof adjustable overpressure protection valve 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 Teflon anodized for reduced friction and wear
• Ergonomic, rugged and lightweight design with comfortable hand grip
