Operating and Safety Information (cont’d)
Use only genuine Sotera replacement parts to assure compatible pressure rating and longest service life.
Install the pump in the vertical (upright) position. The pump may not prime properly if the balls do not check by gravity upon
start-up.
Re-torque all fasteners and rings before operation. Creep of housing and gasket materials may cause fasteners and rings to
loosen. Re-torque all fasteners and rings to insure against fluid or air leakage (torque specifications are on page 8).
Attach proper warning label to pump outlet manifold (label supplied in four languages: part # LB000646-000).
Replacement warning labels are available upon request. Use part number listed above to order replacement.
General Description
The Sotera diaphragm pump offers high volume delivery even at low air pressure and a broad range of material compatibility options are available.
Refer to the model and option chart. Sotera pumps feature modular air motor and fluid sections that are designed to be stall free.
Air operated double diaphragm pumps utilize a pressure differential in the air chambers to alternately create suction and a positive fluid pressure in the
fluid chambers. Ball checks insure a positive flow of fluid.
Pump cycling will begin as air pressure is applied. When cycling, it will build and maintain line pressure, and will stop cycling once maximum line
pressure is reached (dispensing device closed). The pump will resume cycling as needed (as the dispensing device is opened and closed).
Air and Lubrication Requirements
EXCESSIVE AIR PRESSURE can cause pump damage, personal injury or property damage.

A filter capable of filtering out particles larger than 50 microns should be used on the air supply. There is no lubrication required other than the
“O” ring lubricant which is applied during assembly.

If lubricated air is present, make sure that it is compatible with the “O” rings and seals in the air motor section of the pump.
Installation Information
A quick-connect air coupling (D) is required in your system to relieve air trapped between this valve and the pump. Trapped air can
cause the pump to cycle unexpectedly, which could result in serious injury, including splashing in the eyes or on the skin, or contamination from
hazardous fluids.
The pump exhaust air may contain contaminants. Ventilate to a remote area if the contaminants could affect your fluid supply. Read
Air Exhaust Ventilation information that follows ( page 4).
Air Line Installation
Install air supply lines as shown below. Mount all lines and accessories securely on the wall, or on brackets. Use of a pressure regulating device is
mandatory; MAXIMUM LINE PRESSURE IS 100 psi (6.9 bar). Plumb air to the AOD pump as shown:

Rigid air supply lines (A) should be
plumbed to applicable codes and
secured to wall mounts or brackets.

Install a master air shut off valve
(B) to allow for service and
maintenance of the pump.

Install an air filter regulator (C)
(KITS10FRH) to regulate and filter
the air supply to the pump (pump
speed can also be controlled
through this device).

Locate a quick-connect air coupling
(D) between the flex line and air
regulator filter; use it to relieve
trapped air when servicing.

Install flex hose (E) between the
master shut off valve (B) and the air
filter regulator (C). DO NOT install
rigid air lines to the pump; vibration
from pump operation could damage the pump
and /or air and fluid lines.
