SUGGESTED OPERATION AND 
MAINTENANCE INSTRUCTIONS

OPERATION: UX pumps do not require in-line lubrication. Lubrica-
tion will damage the pump! If the pump is lubricated by an exter-
nal source, the pump’s internal seals may be damaged causing
premature failure of the pump.

Pump discharge rate can be controlled by limiting the volume
and/or pressure of the air supply to the pump (preferred method).
An air regulator is used to regulate air pressure. A needle valve is
used to regulate volume. Pump discharge rate can also be
controlled by throttling the pump discharge by partially closing a
valve in the discharge line of the pump. This action increases fric-
tion loss which reduces flow rate. This is useful when the need
exists to control the pump from a remote location. When the pump
discharge pressure equals or exceeds the air supply pressure, the
pump will stop; no bypass or pressure relief valve is needed, and
pump damage will not occur. The pump has reached a “deadhead”
situation and can be restarted by reducing the fluid discharge pres-
sure or increasing the air inlet pressure. The Wilden UX pump runs
solely on clean-dry air and generates little heat, therefore your
process fluid temperature will not be affected.

MAINTENANCE AND 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 affect the parts life of a Wilden pump. Periodic
inspections have been found to offer the best means for prevent-
ing unscheduled pump downtime. Personnel familiar with the
pump’s construction and service should be informed of any abnor-
malities that are detected during operation. Read all cautions
before performing any service on a Wilden pump.

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 down-
time. In addition, accurate records make it possible to identify
pumps that are poorly suited to their applications.
