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 handpump completes the hydraulic circuit. A pressure relief valve can
be set to limit maximum pressure between 30 to 700 bar.

WARNINGS
1BEFORE APPLYING PRESSURE, MAKE SURE ALL CONNECTIONS
ARE
CORRECT AND EQUIPMENT IS INTERNALLY CLEAN AND
FREE
FROM DAMAGE.
2M
AKE SURE THAT ALL EQUIPMENT IS TO THE CORRECT
PRESSURE
RATING.
3D
O NOT EXCEED THE MAXIMUM OPERATING PRESSURE
STATED
IN THE SPECIFICATION.
4O
BSERVE THE RELEVANT HEALTH AND SAFETY PRECAUTIONS.
Note
Wherever possible, use o-ring seals in the connection ports
this is the recommended method of sealing.
Pressure/vacuum Configuration (Figure 1)
In pressure mode, air/fluid is drawn in through the inlet port on the
top of the pump and forced out through the two outlet ports.
In vacuum mode, the air/fluid flow is reversed as air/fluid is drawn
in through the top and rear outlet ports and expelled through the
inlet port.
