EQUIPMENT
The system is comprised of four basic components:
1) Double Diaphragm Pump
2) Two stage air filter/regulator
3) Well level control valve
4) Hoses and fi ings
1)
DOUBLE DIAPHRAGM PUMP (DDP)
• DDP
- The
Double Diaphragm Pump (DDP)
can only be used
above ground and pulls fluid 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 fi ings for both
power air and fluid in and out. (See Figure 1)
2)
TWO STAGE FILTER/REGULATOR
5 and 0.01 micron air filters
-
Two filters mounted on the aluminum plate
remove particulates, oil vapor and water droplets from compressed air. The
pump draws air from the 5 micron filter. The level sensor draws air from
the 0.01 micron air filter.
