HS430S High Pressure Bolted Metal
NOTE:
In the event of a power failure, close the shut-
off valve if you do not want the pump to restart when the
power returns.
Air-Operated Pumps:
To stop the pump from operating in an
emergency, simply close the shut-off valve (user-supplied) installed in
the air supply line. A properly functioning valve will stop the air supply
to the pump, therefore stopping output. This shut-off valve should be
located far enough away from the pumping equipment such that it can
be reached safely in an emergency.
Operation
The HS430S is pre-lubricated,and does not require in-line lubrication.
Additional lubrication will not damage the pump, however if the pump
is heavily lubricated by an external source, the pump’s internal
lubrication may be washed away. If the pump is then moved to a non-
lubricated location, it may need to be disassembled and re-lubricated
as described in the DISASSEMBLY/REASSEMBLY INSTRUCTIONS.
Pump discharge rate can be controlled by limiting the volume and/or
pressure of the air supply to the pump. An air regulator is used to
regulate air pressure. A needle valve is used to regulate volume.
Pump discharge rate also can 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 “Performance”) 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 pressure or increasing the
air inlet pressure. The Wilden High Pressure Pumps run solely on
compressed air and does not generate heat, therefore your process
fluid temperature will not be affected.
Maintenance and Inspections
Because each application is unique, maintenance schedules maybe
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.
