12.1
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.
Brush Kit Life Cycle over 3,000 hours of continuous use. A spare brush kit is located inside of pump housing.
12.2
Cleaning Pump
Pump will require occasional cleaning, especially Injection fitting, Footvalve / Strainer, and pump head valves.
Frequency will depend on type and severity of service.
]
Inspect and replace pump head valves as required.
]
When changing diaphragm, pump head chamber and pump head cover should be wiped free of any dirt and
debris. The pump stroke must be FORWARD when screwing in the diaphragm and BACKWARD when install-
ing and tightening the pump head.
]
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.
]
Periodically inspect pump housing (enclosure) for chemical attack. Protect pump housing from continuous
exposure to chemicals, such as drips or fumes from surrounding equipment and plumbing.
Prior to service, pump clean water through pump and suction / discharge line to remove
chemical.
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.
