4.3 Air supply (pneumatic pump units)
Procedure
1. Connect an air hose to the
compressed-air inlet (A). Use an air
hose with an internal diameter
larger than 3/4".
2. It is recommended to use a filter
regulator lubricator (FRL):
a) Remove the filter cap (B).
b) Fill the air lubricator (C)
halfway with hydraulic oil. Use
only high-grade hydraulic oil
(ISO VG 32 or ISO VG 46 in
more extreme conditions).
c) Install the filter cap (B).
d) Open the air shut-off valve (D).
e) Turn the air pressure regulator
(E) to adjust the air lubricator
(C) to one drop per 60-90 seconds.
f) Close the air shut-off valve (D).
Note: When the pump operates, the pump air pressure must be at least 4
bar.
4.4 Explosion protection (pneumatic pump units)
HYTORC can make the system (pump, hose and tool) explosion proof. The tools will be
equipped with anodized swivels. Metal springs will be fitted onto the couplings of the
swivel, the twin hose and the pump unit. The rubber feet of the pump unit will be replaced
by metal studs.
HYTORC can refit all systems to meet the ATEX-requirements conform:
• EPS 13 ATEX 2 561 X
• EX II 2 G EX c IIB T4
• CE
Warning:
• Only use ATEX-certified pneumatic pump units, hydraulic hoses and tools
in areas with explosion hazard.
• Let authorised personnel inspect the explosion-proof system on a regular
basis.
Procedure
1. Make sure that all couplings and other connections are tight.
2. Connect a multimeter between the tool and one end of a grounding wire to measure
the conductivity.
3. Connect one end of the grounding wire to the pneumatic pump unit.
4. Connect the other end of the grounding wire to an earthing point.
