Druck PV 411 User Manual Connecting the Pump Connections can be made to the pump either directly or using the range of adaptors supplied in the optional test kit. Direct The ports can be fitted with any suitable length 1/4 BSP male connector, sealing either with an o-ring at the bottom of the port or a bonded seal at the top. -

Druck PV 411 User Manual Pneumatic Operation Volume Adjuster The volume adjuster can be used in different modes: Low pressure With the selector valve set to vent (open), turn the volume adjuster fully anti-clockwise (out). Turn the selector valve to the fully clockwise (in) position to select pressure. -
Page 12: Generating Pneumatic Pressure And Vacuum
Druck PV 411 User Manual Generating pneumatic pressure and vacuum Connect the pump as detailed on page 5. Notes Compressing a gas generates heat. Gas heated or cooled in an enclosed volume causes a pressure change. It is important to allow enough time for the heated gas to cool and the pressure to stabilize. - Page 13 Druck PV 411 User Manual After attaining the required vacuum operate the scissor-action handles to generate a higher vacuum. Alternatively, vent atmosphere into the vacuum by slowly turning (anti-clockwise) the selector valve to the centre position. After completion, depressurize the pump and disconnect from the pipes and equipment.

Page 17: Priming The System
Druck PV 411 User Manual Priming the system There are two methods: vacuum priming to extract the air or pre- filling the system. Notes: If air remains in the system, full pressure cannot be achieved as the air in the fluid compresses. Air must be removed from the system fluid. -
Page 18: Pre-Filling
Druck PV 411 User Manual Pre-filling Connect the equipment as detailed on page 5. Turn the selector valve fully clockwise (in) position. Loosen the reservoir cover lock nut to open the reservoir cover and let atmospheric pressure into the top of the reservoir. -

Druck PV 411 User Manual Generating Hydraulic Pressure Note Pressurizing a fluid generates heat. A fluid heated or cooled in an enclosed volume causes a pressure change. Allow enough time thermally stabilize. Open the selector valve anti-clockwise 1 turn. Screw the volume adjuster fully out (anti-clockwise). -

Druck PV 411 User Manual Multimedia Changing from fluid to gas: Turn the volume adjuster fully clockwise (in). Use the vacuum selection, operate the scissor-action handles to draw fluid into the reservoir. Depressurize the pump. Unscrew and remove the reservoir. -
Page 21: Fault Finding
Druck PV 411 User Manual Fault Finding If system pressure reduces, check the following: Check the selector valve is in the correct position and properly tightened. Allow sufficient time after pressure generation for the temperature to stabilize. Check the adaptors, flexible pipe and connections between the pump and equipment under test for leaks. -
