SERVICE AND OPERATING INSTRUCTIONS
This Versa-Matic ® Surge Suppressor is a completely automatic diaphragm fitted
surge suppressor to reduce the flow and pressure pulsations in a pumping system
characteristic of reciprocating type pumps.
Principle of Operation: The Surge Suppressor uses a flexible diaphragm to separate a
liquid chamber from compressed air chambers. A rod connected to the center of
one diaphragm activates the air inlet and exhaust valves, which automatically admit
or exhaust air in the air chambers. This maintains the diaphragms in mid-range of
stroke for maximum surge suppression.
Installation: Locate the Surge Suppressor in discharge piping as close as possible
to the pump. The unit will operate in any position. Connect air inlet connection to
full plant air supply line before the air regulator to pump. Not to exceed 125PSI.
Service Instructions: When service is required, it is important to MAKE CERTAIN
THAT INLET AIR PRESSURE IS DISCONNECTED. The diaphragms are serviced
by simply removing the hex nuts or v-band, and removing the center spool casting.
When Virgin PTFE diaphragms are used in conjunction with the elastomeric
diaphragms they are placed over the “wetted” sides of each elastomeric diaphragm.
Inlet and exhaust air valves are located externally for easy access and service.
Warranty: This unit is guaranteed for a period of five years against defective
material and workmanship.
Before surge suppressor
operation, inspect all
gasketed fasteners for
looseness caused by
gasket creep. Re-torque
loose fasteners to prevent leakage. Follow
recommended torques stated in this manual.
CAUTION
IMPORTANT
Read these safety warnings
and instructions in this
manual completely, before
installation and start-up
of the pulsation dampener.
It is the responsibility of the purchaser to retain
this manual for reference. Failure to comply with
the recommendations stated in this manual
will damage the pulsation dampener, and void
factory warranty.
Before doing any maintenance
on the pulsation dampener,
be certain all pressure is
completely vented from the
pump, suction, discharge,
piping, and all other openings and connections.
Be certain the air supply is locked out or made
non-operational, so that it cannot be started
while work is being done on the pump. Be certain
that approved eye protection and protective
clothing are worn all times in the vicinity of the
pump. Failure to follow these recommendations
may result in serious injury or death.
WARNING
Take action to prevent static
sparking. Fire or explosion
can result, especially
when handling flammable
liquids. The pump, piping,
valves, containers or other
miscellaneous equipment
must be grounded. See page 8.
WARNING
POSSIBLE EXPLOSION HAZARD can result if
1, 1, 1, -Trichloroethance, Methylene Chloride
or other Halogenated Hydrocarbon solvents
are used in pressurized fluid systems having
Aluminum or Galvanized wetted parts. Death,
serious bodily injury and/or property damage
could result. Consult with the factory if you
have questions concerning Halogenated
Hydrocarbon solvents.
