Accurate records from the early stages of pump operation will indicate the type and levels of required
maintenance. A preventative maintenance program based on such records will minimize operational
problems. It is not possible to forecast the lives of wetted parts such as diaphragms and check valves.
Since corrosion rates and operational conditions affect functional material life, each metering pump must
be considered according to its particular service conditions.
The OMNI
®
KOPkit will contain all replacement parts normally used in a preventative maintenance
program. It is recommended that KOPkits and PulsaLube EP Gear Oil be kept available at all times.
