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.
PULSAR Shadow® KOPkits contain all replacement parts normally used in a
preventative maintenance program. It is recommended that KOPkits and PULSAlube
eccentric and gear oils be kept available at all times.
