Versa-Surge Suppressor

OPERATING AND SERVICE INSTRUCTIONS
This Versa-Matic Versa-Surge is a completely automatic diaphragm fitted surge
suppressor to reduce the flow and pressure pulsations in a pumping system charac-
teristic 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 automati-
cally admit or exhaust air in the air chambers. This maintains the diaphragms in mid-
range of stroke for maximum surge suppnession.
Installation: Locate the Surge Suppressor in discharge piping as close as possible
to the pump. The unit will operate in any position. Connect the air inlet connection
to the air supply line having the same air pressure as that at the air inlet connection
to the pump. Do not exceed 125 PSI.
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 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
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

pumping certain chemicals. Consult engineer-
ing guides for chemical compatibilities and tem-
perature limits.
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.
