CLEANING AND MAINTAINING THE VACUUM PUMP
PIAB vacuum pumps are easy to clean and maintain. The only wear parts in the pumps are flap valves
and gaskets. A slow, gradual loss in vacuum could be attributed to cracked gaskets or flap valves.
Please refer to pages 26 for a spare parts breakdown. The spare kits include all of the necessary flap
valves, gaskets, and a compressed air filter.
A slow gradual loss in vacuum could also be attributed to product moving through the pump. If any
material has come out of the exhaust, chances are the pump needs to be cleaned out.
Classic and L 100 vacuum pumps
The pump should be opened up and examined. Please refer to page 31 for a diagram and parts break-
down of the Classic 100. First the panel plate should be removed, and then the side plate. The valve
plate and side plate gasket is now visible. Located underneath the valve plate are the flap valves. Are
the gaskets or flap valves cracked? If so, the repair kit 32.01.069 should be purchased. The vacuum
chambers and nozzles should now be visible. Is the material that is being conveyed in the chambers or
nozzles? For optimum performance, there should not be any material in the pump. The pump's perfor-
mance decreases as more material gets lodged in the nozzles. Please be careful when cleaning the
pump. If a nozzle is broken off or rotated, the pump will need to be replaced. To remove material from
the nozzles or chambers, PIAB suggests soaking the pump in water or in water with mild detergent such
as dishwashing detergent. Once the pump has new seals and flap valves and it is clean and put back
together, it should run just like a brand new pump.
L100, L200, L400, L600, L800, L1200, L1600 vacuum pumps
The pump should be opened up and examined. Please refer to page 26-30 for a diagram and parts
breakdown of the vacuum pump. First the left side plate and gasket should be removed. This should ex-
pose the vacuum chambers and nozzles. If the vacuum port is facing down, then the flap valves are lo-
cated at the top of each vacuum chamber. Are the gaskets or flap valves cracked? If so, the appropriate
repair kit should be purchased. Is the material that is being conveyed in the chambers or nozzles? For
optimum performance, there should not be any material in the pump. The pump's performance decreas-
es as more material gets lodged in the nozzles. Please be careful when cleaning the pump. If a nozzle
is broken off or rotated, the pump will need to be replaced. To remove material from the nozzles or
chambers, PIAB suggests soaking the pump in water or in water with mild detergent such as dishwashing
detergent. Once the pump has new seals and flap valves and it is clean and put back together, it should
run just like a brand new pump.
