Shut down and Displacement Pump Cleaning
Procedure
NOTE: The pump and the system should be
cleaned in accordance with your state and
sanitary codes and local regulations.
Remove the pump from the fluid container and
operate the pump until as much of the material as
possible has been pumped out.
Flush the system thoroughly with warm cleaning
solution.
Shut off the air to the pump and relieve the fluid
pressure by opening the automatic dispensing
valve. Remove the air and fluid hoses from the
pump.
Disassemble the fluid pump and accessories.
Wash all the pump parts with an alkaline detergent
at the manufacturer’s recommended temperature
and concentration, using either a brush or other
C.O.P. methods.
Rinse all the pump parts again with water.
Allow all the pump parts to dry.
Inspect all the pump parts and reclean any soiled
parts. Any damaged rubber parts must be
replaced because they will harbor micro-
organisms.
Immerse all the pump parts and the tube of
lubricant in an approved sanitizer before assembly.
Leave the pump parts in the sanitizer during
assembly, taking them out one by one as needed.
Lubricate the moving pump parts and o-rings,
packings and seals with waterproof sanitary
lubricant.
Circulate the sanitizing solution through the pump
and the system prior to use.
SERVICE
WARNING
Moving parts can pinch or amputate your
fingers or other body parts. When the pump is
operating, the priming piston (located at the
pump intake) and the air motor piston (located
behind the air motor shield) move. Therefore,
NEVER operate the pump with the air motor
should removed, and keep your fingers and
hands away from the priming piston.
Before attempting to clear an obstruction from
the priming piston or service the pump, follow
the Pressure Relief Procedure Warning on
page 2 to prevent the pump from starting
accidentally.
