A.O.D.D. PUMPS with PipeGuard PLAS - PiG-PLAS
Application Story

For Plastic & A.O.D.D. PUMP systems
PipeGuard/PLAS & Air Operated Double ended Diaphragm pumps
PDF of this page


An A.O.D.D. could not suck water treatment chemicals from the 10ft high (3 meters) plastic drum stillage because it was 70ft (30 meters) away.
TECH. Notes: It is not necessary to read the areas shaded in this color. The good thing about an A.O.D.D. is that it jumps straight up to a constant flow rate after each stroke reversal, giving you a pretty smooth discharge flow (if the air line is large enough). The down side is: that it is difficult to fill instantaneously on the suction side.

If you do not need in-place flush-through, and wish to provide "T" pieces, use the extra connection for relief valve, system drain, or a gauge.

PIPEGUARD a Below was fitted to the pump inlet. Loss of suction power was avoided by eliminating flow reversal within - out twice connection continuous flow configuration, standard choice of damper type PiG-Plas/TW

The A.O.D.D.
1. Can now fill - and pump.
2. Pumps at twice the rate through possible.
3. Pipe shake and breakage has ceased.
A PIPEGUARD PLAS from PVC was installed item b on the pump outlet, and the chemicals can now be pushed also to a mixing tank 320 ft (say 100 Meters) away.
Many different chemicals are handled buy the one system because the inlet - outlet twin hole through flow, enables flushing.

Selecting Pulsation Dampeners for Different Pump Systems.
Flow through pulsation dampers are at least 3 times more efficient than T off line accumulators.
Dampeners that do, flow goes through, but pressure pulsation does not.
