How to Maintain Pump
Always wear protective clothing, face shield, safety glasses and gloves when working on
or near your metering pump. Additional precautions should be taken depending on
solution being pumped. Refer to MSDS precautions from your solution supplier.
!
CAUTION
Routine Inspection and Maintenance
Pump requires very little maintenance. However, pump and all accessories should be checked weekly. This is
especially important when pumping chemicals. Inspect all components for signs of leaking, swelling, cracking,
discoloration or corrosion. Replace worn or damaged components immediately.
Cracking, crazing, discoloration and the like during first week of operation are signs of severe chemical attack. If this
occurs, immediately remove chemical from pump. Determine which parts are being attacked and replace them with
parts that have been manufactured using more suitable materials. Manufacturer does not assume responsibility for
damage to pump that has been caused by chemical attack.
How to Clean and Lubricate Pump
Pump will require occasional cleaning. The amount will depend on severity of service.
]
When changing pump tube assembly, pump head chamber, roller assembly and pump head cover should be wiped
free of any dirt and debris.
]
Pump head cover bearing may require grease periodically. Apply a small amount of grease (Aeroshell aviation
grease #5 or equivalent) when necessary.
]
Although not necessary, 100% silicon lubrication may be used on the roller assembly and tube assembly.
]
Periodically clean injection/check valve assembly, especially when injecting fluids that calcify such as sodium
hypochlorite. These lime deposits and other build ups can clog fitting, increase the back pressure and interfere with
check valve operation.
]
Periodically clean suction strainer.
