The PV411A is a high quality field proven pressure and vacuum hand pump providing functionality, which has never been seen before in a hand held pressure source. This
remarkable product replaces four conventional hand pumps and offers the following additional features:

• 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 lightweight design with comfortable hand grip
