Versa-Matic Versa-Surge Surge Suppressors for Air-Driven Diaphragm Pumps Metallic - Manual (Page 2)

Versa-Surge
• Nearly surge-free flow.
• Steadier pressures.
• Less shock to pipes.
Air-operated diaphragm pumps offer a wide range of
benefits not available in any other type of pump. However,
in some applications, pulsations in the discharge flow may
be undesirable. Pulsation can be virtually eliminated by
installing a Versa-Matic Versa-Surge.
At initial and subsequent start-ups . . . air cushion is
quickly established by liquid pressure pushing diaphragm
upward, permitting entrance of air into air chamber, until
the balancing air cushion causes the diaphragm to center
at its mid-stroke normal operating position.
During normal continuous operation thereafter . . . the
diaphragm always flexes at its mid-range position to absorb
discharge pulsations against the adjoining air cushion
already established.
In event of change in pumped liquid pressure . . . the
air cushion pressure is automatically increased or
decreased as required to compensate for the change . . .
always maintaining constant volume of air cushion, and
the diaphragm always operating at its mid-position.
When liquid flow stops and liquid pressure is released
. . . the air in air chamber is also exhausted to atmosphere.
Versa-Surge
• Automatically maintains a constant volume of air
cushion for most effective surge suppression,
regardless of pump pressure.
• Automatically self-charging and self-venting to maintain
most efficient air cushion pressure . . . no more
precharge pressure calculations or guesswork, no
manual pressurizing, no periodic pressure checking.
• Air cushion separated from product by flexible diaphragm
. . . prevents product aeration.
• External visual indication provides constant evidence of
performance.
• Simple to install. Attention-free.
