1. Introduction
The PV 411A 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.
1.1 Pneumatic Pump (Figure A1)
A selector valve (7) vents the system, to atmosphere,
between selections of pressure and vacuum. Operating the
scissor-action handles (5) provides the pumping stroke, for
pressure generation.
A volume adjuster (3) allows small adjustments of the
system pressure.
1.2 Hydraulic Pump (Figure A1)
The selector valve (7) vents the system, to the reservoir,
between selections of pressure and vacuum (used in the
priming process). The volume adjuster (3) generates the
required system pressure. A fluid reservoir (see Figure A2),
screwed into the inlet port (1), marked RESERVOIR, on the
top of the hand-pump completes the hydraulic circuit. A
pressure relief valve (8) can be adjusted to set a pressure
between 30 and 700 bar (500 to 10,000 psi).
* A qualified technician must have the necessary technical
knowledge, documentation, special test equipment and
tools to carry out the required work on this equipment.
