Operation
3A0591ZAG 13
Starting and Adjusting the Ram
1. Close all air regulators and air valves.
2. Turn on the main air supply.
3. Open the main air valve (BA), and set the ram
director air regulator (BB) to 2.8 bar, 0.26 MPa (40
psi). Set the director valve (BC) to UP and let the
ram rise to its full height.
4. Lubricate inflatable seal (C) with sanitary lubricant.
5. Set a full drum of fluid on the ram base, slide it back
against the tube stop, and center it under the
follower plate.
6. Remove the drum cover, and smooth the surface of
the fluid with a straightedge.
7. Secure the bag liner to the drum with tape or a
strap, to prevent it from sliding into the drum.
8. Set the director valve to DOWN. Set ram air
regulator at about 40 psi (0.28 MPa, 2.8 bar). Lower
the ram until the ram plate is about to enter the
drum, and set the valve to neutral. Reposition the
drum as necessary so the inflatable seal does not
hit the drum lip.
Exposed Controls: To increase or decrease the speed
of downward travel on the ram plate, adjust the director
valve (BC).
9. Set the director valve to DOWN, and continue to
lower the ram until the ram plate contacts the fluid.
10. Set seal air pressure regulator to pressure
determined in Setting Inflatable Seal Pressure ,
page 12. Set the inflatable seal switch to On to
inflate seal.
NOTE: If fluid leaks past the seal, increase the air
pressure to the seal gradually until leaking stops. To
prevent overpressurization, a relief valve limits seal
pressure to 30 psi (2.1 bar, 0.21 MPa).
WARNING
• Do not inflate the seal when not
installed on the follower plate. Wear
safety glasses when operating the
seal. Seal burst could result in injury.
• Keep hands and fingers away from the
ram plate, pump fluid inlet, and lip of
the fluid container when raising or
lowering the ram to reduce risk of
serious injury from moving parts.
NOTICE
Do not use drums that have side bungs or large dents
with this ram. Rough bung openings or large dents will
damage the inflatable seal or stop the ram plate,
resulting in a runaway pump.
