Druck four-in-one hand pump Features • Hydraulic pressures to 10,000 psi • Pneumatic pressures to 600 psi • Vacuum to 28.5 in Hg • Low pressure fine control 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
