Flush Before First Use
The sanitary pump was assembled using sanitary lubri-
cant 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.

1.
Set an empty drum on the ram base. Set the direc-
tor valve (BC) to DOWN. Lower the seal into the
drum to the point of the drum’s largest inside diame-
ter.

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 overpres-
surization, a relief valve limits seal pressure to 30 psi
(2.1 bar, 0.21 MPa).

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.
