Performance & Specifications
Pump Performance Is Dependent On Cycle Rate of The Pump Air Cylinder & The Plumbing Head.
l Volume is expressed in GPM (gallons per minute) and LPM (liters per minute)
l A Cycle Rate is one up and down stroke of the cylinder. Maximum cycles rate for this pump
should not exceed 60 per minute. Over 60 cycles per minute the pump begins to cavitate.
l Head conditions are determined by the height, length and size of the installation plumbing
connected to the inlet and discharge of the pump base.
General Performance Specifications:
l Static Head: Suction 20 ft / 6.1m Discharge 18 ft / 5.47m (1 1/2" Hose or Pipe)
l Dry Suction Lift: 17 ft / 5.18m (1 1/2"ID Pipe or Hose)
l Continuous Duty Discharge Heads: Should be Limited to 10 ft. / 3m
l Performance: 20 GPM / 75.7LPM at 5 ft Suction Lift and 0 Discharge at
60 Cycles per Min. w/ 1 1/2" Pipe
Volume Charts:
l Use the following charts as guides to determine the performance volume at different cycle rates
with the pump installed with a variety of suction and discharge plumbing conditions.

Installation Guidelines
Step 1 Check All Bolts - Make sure that all bolts on the pump are tight. Tools: 2ea. 9/16”, 1/2” and
7/16” Box Wrenches & 1 Allen Wrench.
7/16”
Upper Standard
& Head Ring
1/2”
9/16”

Locking Nut
Cylinder Mounting Nuts (Not Shown)
Step 2 Place Pump - The pump must be installed so that the flapper valves will open and close. The drawings
below show how the pump can and can not be installed in relationship to its’ horizontal and vertical axis.

P-220A-03
Step 4 Connect The Air Line - Air line should be at least 1/4” pipe or hose. It should deliver at least 8 ACFM and
regulated between 85 and 95 psi. The air line is connected to the 3/8” FNPT located between the two
exhaust regulator filters.
Step 5 Speed Control Muffler - The needle valve that is part of this exhaustPXIIOHU is used to adjust the speed of
the down stroke and up stroke of the cylinder. Using this adjustment the cycle rate of the pump was set to
60 cycles per minute
Important
Air Pumps are factory set to 60 cycles per minute with the input air
holding at 85 psi run pressure and no liquid being pumped.

Air Line Connection
Speed Control Muffler
Part No.161-A-2990
controls the speed of the
down stroke of the cylinder
Important
Do not control pump cycle rate by increasing or decreasing air line pressure.
Air line pressure should always be kept between 85 and 95 psi.
Step 6 Practice Adjusting The Pump Cycle Rate - There are two ways to control the cycle rate. The first is by
adjusting the needle valves of the Exhaust Regulator Filter. The second is by using an air flow control valve
on the air line between the pressure regulator and the air cylinder. You can use either or a combination of
both adjustments to set the pump performance you need once the plumbing is installed and liquid is being
pumped.
1. Open the air line.
2. Set air line pressure to 90 psi.
3. Using a very small flat head screwdriver start closing (clockwise) the right hand solenoid needle valve. The
down stroke of the air cylinder should start slowing down.
4. Now close the upper needle valve. The up stroke of the air cylinder should start to slow.
5. Now reset the cycle rate to 60 cycles per minute by opening each needle valve till you are getting one
down stoke per second and you perceive that the timing on the up stroke and the down stroke is
approximately the same. Use a watch with a sweep second hand to time the cycle rate.
6. Now open and close the air flow control valve if you want to use one and note the change in cylinder
speed.
