Note
Connections of the pump
♦ Compressed air
Air inlet in head of airmotor.
Female thread ¼“ NPTF
♦ Material to be pumped
Material outlet in outlet casting of the pump.
Female thread ¼“ NPTF
To operate pump the manufacturer/supplier of the
complete system has to supplement the pump by air
and fluid system components being required for the
individual application.
Ask for standard accessories in case of requirement.

5.1 Air supply
Air flow
Air lines and components must have an adequate size
(inside dia.) to allow an unrestricted air flow to pump.
They must not cause pressure drop during normal
operation on increase of pump cycles.
For information about air consumption
⇒ Refer to 3.
3 ‘Technical Data’
Air pressure
The minimum air pressure to operate pump is
2,1 bar. The air pressure being required depends on the
individual application.
The max. air pressure permitted to operate the pump
can occasionally be lower than the max. working
pressure of the airmotor. The max. air operating
pressure depends amongst others on the fluid system
components. Always pay attention to the pressure ratio
of the pump which transforms the air pressure in a
50-times higher fluid pressure.
⇒ Refer to 3.
3 ‘Technical Data’
⇒ Refer to specifications of system components.
3.5.2 Pneumatic system components
The working pressure of pneumatic components must
comply with the pressure (primary / secondary air
pressure) applied to the equipment.
The nominal size (I. D.) of air pressure regulator,
FRL-Air service unit, valves, couplings, etc. shall
normally correspond to the size of the inlet to the
airmotor which is 1/4“ (I.D. 6 mm).
Check if components are designed for air flow required
for the appropriate use!
The connecting point of the air supply line shall be
equipped with an air shut-off valve.
For each pump/pump unit following items are required
• One Air pressure regulator with gauge
• One Air connecting hose
of sufficient length
• One Air quick-coupler
If the compressed air is not clean or is not free from
moisture, use
• One Air filter
We recommend to use a FRL-Air service unit
(Filter, regulator, gauge and lubricator).
If the primary air pressure is higher than the max.
working pressure (air) of the pump or the output
pressure resulting from the pump pressure ratio
exceeds the max. permissible fluid pressure of the
equipment, you also need:
• One Air pressure reducer and safety device
Important note: When using pumps/pump units as
mobile equipment, safety devices must be mounted
directly to the pump. Mobile equipment means that the
pump can be used at different places of operation
and/or the connecting point of the air supply to pump is
not fixed.
• Low level device (Pump shut-off device)
should be used for pumps/pump units in automated
applications or when pump is not permanently
monitored by the operator. Shut-off device prevents
‘run-away’ of pump when out of material and avoids
premature wear and/or damage.
Additional pneumatic components being required to
operate pump are not listed and depend on the
individual application.
3.5.3 Material supply line
Take viscosity or NLGI-class of the material to be
pumped and the lengths of the material line into account
when selecting nominal size (I.D.) of supply line and
system components.
All system components have to comply with the
specifications concerning max. working pressure and
the compatibility with the material to be pumped.
Use control valve (gun) with heavy duty nozzle
designed for power operated lubricating devices when
operating pump as lubricator.
We recommend to use LINCOLN control valve no. 740.

5.4 Optional pump accessories
General
Install pump securely upright for operation. Use for
example drum cover, and additionally mounting devices
if required.
• One Drum Cover
(for centering pump on top of barrel)
Drum cover for container-Ø (O.D.)
No. 81523-E025 330-370 mm
No. 81523-E050 380-435 mm
No. 81523-E200 570-600 mm
If the dip length of the pump tube must be adjusted to
the height of the container, then attach to drum cover:
One No. 12643-E059 mounting kit.
For pumping non-fluid lubricants, use:
• One Follower plate for grease
Follower plate for container-Ø (I.D.)
No. 83366-E025 310-330 mm
No. 83366-E050 375-400 mm
No. 990004-E 350-360 mm
No. 83366-E200 570-575 mm
