17.0 Pump Maintenance
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.
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 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. 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.
] When changing pump tube assembly, wipe motor shaft with clean towel. Apply a small amount of grease to
shaft. This will help prevent possibility of rotor sticking to motor shaft.
] 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 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 back pressure and interfere with
check valve operation.
] Periodically clean suction strainer.
