Introduction
The PV 411 hand-pump generates either pneumatic pressure and
vacuum or hydraulic pressure. The scissor-action handles provide
pneumatic pressure and vacuum generation and, in the hydraulic
mode, provides hydraulic pressure generation for system priming.
Pneumatic pump (Figure 1)
A selector valve vents the system, to atmosphere, between
selections of pressure and vacuum. Operating the scissor-action
handles provides the pumping stroke, for pressure generation.
A volume adjuster allows small adjustments of the system
pressure.
Hydraulic pump (Figure 1)
The selector valve vents the system, to the reservoir, between
selections of pressure and vacuum (used in the priming process).
The volume adjuster generates the required system pressure. A
fluid reservoir, screwed into the inlet port on the top of the hand-
pump completes the hydraulic circuit. A pressure relief valve can
be set to limit maximum pressure between 30 to 700 bar.
