OPERATION: The H38/3200D is pre-lubricated and does not

require in-line lubrication. Additional lubrication will not dam-

age the pump, however if the pump is heavily lubricated by an

external source, the pump operation may be affected. It may

need to be disassembled and re-lubricated as described in

the ASSEMBLY/DISASSEMBLY INSTRUCTIONS.

Pump discharge rate can be controlled by limiting the vol-

ume and/or pressure of the air supply to the pump (preferred

method). A regulator is used to control air pressure while a

needle valve is used to control 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 friction loss which reduces flow rate.

(See Section 5.) This is useful when the need exists to control

the pump from a remote location. When the pump discharge

pressure equals or exceeds approximately 26 times the air

inlet 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 pressure or increas-

ing the air inlet pressure. The H38/3200D pump runs solely

on compressed air and generates little heat, therefore your

process fluid temperature will not be affected.

MAINTENANCE AND INSPECTIONS: Since each applica-

tion 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 preventing unscheduled pump

downtime. Personnel familiar with the pump's construction

and service should be informed of any abnormalities that

are detected during operation.

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.
