Operation
Pressure Relief Procedure
Do not close the main air valve until Step 6. The
Enclosed Air Controls will not operate when the main air
supply is in the Off position.
1. Close the air motor slider valve (BF). See F
2. Back the ram director air regulator down to zero. Set
the ram director switch/valve (BC) to DOWN. The
ram will slowly drop.
3. Jog the director valve up and down to bleed air from
ram cylinders.
4. Turn the inflatable seal switch (BJ) to off.
5. Open the fluid ball valve and/or dispensing valve to
relieve fluid pressure.
6. Close the main air valve (BA).
Flush Before First Use
The sanitary pump was assembled using sanitary
lubricant on moving parts and was tested in water. Flush
the pump thoroughly with an appropriate cleaning
solution or disassemble and sanitize the parts before
using the pump. See your separate pump manual for
complete flushing and cleaning procedures for a
sanitary pump. Check national, state, and local codes
for specific limitations.
Setting Inflatable Seal Pressure
1. Set an empty drum on the ram base. Set the
director valve (BC) to DOWN. Lower the seal into
the drum to the point of the drum’s largest inside
diameter.
2. Set the inflatable seal switch (BJ) to On. Adjust the
seal air regulator until the seal just touches the
inside of the drum.
3. Leave regulator set at this setting for this style of
drum.
4. Set the inflatable seal switch to Off to deflate seal
before raising the ram. Set the director valve (BC) to
UP and let the ram rise to its full height.
5. Remove the empty drum.
NOTE:
Use the lowest seal pressure possible to
achieve desired results. Excessive seal pressure may
cause the seal to roll off of the follower plate. To prevent
overpressurization, a relief valve limits seal pressure to
30 psi (2.1 bar, 0.21 MPa).
WARNING
Trapped air can cause the pump to cycle
unexpectedly, which could result in serious
injury from injection, splashing or moving
parts. Relieve pressure when you stop
pumping and before cleaning, checking, or
servicing equipment.
