SERVICE AND OPERATING MANUAL
Model VDA05 ½" Surge Dampener
Model VDA07 ¾" Surge Dampener
Model VDA10 1" Surge Dampener
The Versa-Matic Surge Dampener reduces ow and pressure pulsation which is
characteristic of reciprocating pumps.
PRINCIPLE OF OPERATION
The surge dampener uses a exible virgin PTFE diaphragm to separate a liquid
chamber from a compressed air chamber. After the dampener is manually
charged with air, the diaphragm strokes at the same rate as the pump strokes.
This movement effectively "dampens" ow and pressure uctuations.
TEMPERATURE LIMITATIONS
Operating temperature limitations are as follows.
Material Minimum Temp. Maximum Temp.
PVDF 0°F/ -18°C 212°F / 100°C
Nylon 32°F/ 0°C 180°F / 82°C
Polypropylene 32°F/ 0°C 180°F / 82°C
Virgin PTFE -35°F/ -31°C 212°F / 100°C
Nitrile -10°F/ -23°C 190°F / 88°C
INSTALLATION & START-UP
Locate the unit in the discharge piping near the pump. The dampener will operate
in any position. However, when used with liquids that tend to settle out, the unit
should be installed at the top side of piping to provide easy discharge of foreign
solids by gravity.
Adjust the inlet air pressure to the dampener until the pump runs as smoothly
as possible. Watch the liquid discharging, or use a gauge, to detect pressure
uctuations. Then adjust pressure to the unit as needed.
IMPORTANT
Read these safety warnings
and instructions in this
manual completely, before
installation and start-up
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 surge dampener, and void factory
warranty.
Maximum
operating pressure
is 100 psi (7 bar).
Limitation are
based upon mechanical stress only and may
be signicantly altered by pumping certain
chemicals. Consult engineering guides for
chemical compatibilities and temperature limits.

gasket creep. Re-torque
NOTE: Self-relieving regulator 020-039-000 will make these adjustments easier.
SERVICE
When service is required on the dampener, remove the 8 capscrews. The wetted
chamber can be removed from the unit and exposes the diaphragm. Remove the
diaphragm. When reassembling the wetted chamber onto the air chamber, use
a torque wrench set at 70 in/lbs. (7.9 Newton meters)
WARRANTY
This unit is guaranteed for a period of ve years against defective material and
workmanship.

Repair Parts shown in bold face (darker)
type are more likely to need replacement
after extended periods of normal use. They
are readily available from most Versa-Matic
distributors. The pump owner may prefer to
maintain a limited inventory of these parts
in his own stock to reduce repair downtime
to a minimum.
IMPORTANT: When ordering repair parts
always furnish pump model number, serial
number and type number.
