pv_411a hand pump

PV411 Hand Pump

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 over pressure protection valve which can be set to relieve pressures from 30 to 700 bar * 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 550 mbar * 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
