INTRODUCTION
The Automatic Double Diaphragm Pump (ADDP) system is designed to
automatically maintain a uid level in a well or tank by sensing the uid level and
removing uid which rises above the sensor. The ADDP system is powered by
compressed air and requires no electricity. It is capable of ows from 0 to 15 gallons
per minute (GPM), liing from 22 feet or less below ground at sea level, and pushing
with a force of 100 psi (231 feet of water column).

Chapter 1: Equipment
EQUIPMENT
The system is comprised of four basic components:
1) Double Diaphragm Pump
2) Two stage air lter/regulator
3) Well level control valve
4) Hoses and ings
1) DOUBLE DIAPHRAGM PUMP (DDP)
• DDP - The Double Diaphragm Pump (DDP) can only be used
above ground and pulls uid from 22 feet or less below ground at
sea level.
• Needle valve - The DDP has an adjustable needle valve to
control its rate of cycling and quick connect ings for both
power air and uid in and out. (See Figure 1)
2) TWO STAGE FILTER/REGULATOR
5 and 0.01 micron air lters - Two lters mounted on the aluminum plate
remove particulates, oil vapor and water droplets from compressed air. The
pump draws air from the 5 micron lter. The level sensor draws air from
the 0.01 micron air lter.

• The rst air lter/regulator (5 micron particulate lter) has a gauge and
quick connect ings for the compressed air coming from the compressor.
This lter has an automatic drain valve which activates when the uid level
rises in the lter bowl. (See Figure 1)
• The second air lter for the bubbler sensor system (0.01 micron oil
coalescing lter) has a needle valve to control the air bubbler rate. This lter
also has an automatic drain valve which activates when the uid level rises
in the lter bowl. (See Figure 1)

3) WELL LEVEL CONTROL VALVE
• The well level control valve is mounted on top of the two stage lter/regulator
assembly. It uses a well level sensor hose down well to sense the uid level
in the well. It supplies air to the DDP when the uid level rises and shuts the
DDP o when the uid level recedes. (See Figure 1)
System with Foot Valve:
• The pneumatic sensor circuit has an air bubbler connected to the 1/4 inch
well level sensor hose via a quick connect. (See Figure 2)
System with Top Loading Cup:
• The pneumatic sensor circuit has an air bubbler located inside the top
loading cup. (See Figure 3)
