Suggested Installation, Operation, Maintenance and Troubleshooting
Operation
For best results, the pumps should use an air filter and a
regulator. The use of an air filter before the pump inlet will
ensure that the majority of pipeline contaminants will be
eliminated. The solenoid operated pump is permanently
lubricated during assembly, and requires no additional
lubrication under normal operation. If the unit runs under
extreme conditions (continuous operation at high speeds),
it may be necessary to relubricate the center block with a
Buna-N compatible NLGI Grade 2 grease every 50 million
cycles. Continuous lubrication with a compatible oil is not
harmful, and will provide longer seal life, but it may flush all
grease out of the unit.
The pump will not shift reliably unless the minimum supply
pressure is provided. For the A.025T the minimum supply
pressure for reliable operation is 2.7 bar (40 psig).
A muffler can be installed to reduce the amount of noise generated
by the pump. Use of the specified Wilden muffler will reduce noise
levels below OSHA specifications.
Maintenance and Inspections
INSPECTIONS: Since each application is unique, maintenance
schedules may be different for every pump. Frequency of use, line
pressure, viscosity and abrasiveness of process fluid all effect the
parts life of a Wilden pump. Periodic inspections have been found to
offer the best means for preventing unscheduled pump downtime.
Personnel familiar with the pump’s construction and service should
be informed of any abnormalities that are detected during operation.
Internal maintenance is not recommended for Accu-Flo™ solenoid air
valves. When worn or damaged, a new air valve body, coil or terminal
connector must be purchased. Please consult section 9 for part
numbers.
RECORDS: When service is required, a record should be made of all
necessary repairs and replacements. Over a period of time, such
records can become a valuable tool for predicting and preventing
future maintenance problems and unscheduled downtime. In
addition, accurate records make it possible to identify pumps that are
poorly suited to their applications.
