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.
