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.

Pneumatic pump

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.

Hydraulic pump

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 2), 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.
