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), liing 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)
