For best performance and life, the pump should be installed in
the vertical position. This will prevent side loading on the air
piston seals. The pump will, however, function in any position.
The pump will attach to the mounting location using (4) 1/2"
bolts. There are 4 holes provided on each pump for mounting.
Section 6.1
Compressed Air Supply
The main air drive connection port on the pump is a female 3/4"
FNPT and is located in the spool valve housing. An additional
female 1/8" FNPT air pilot valve connection port is located in
the bottom cap next to the spool housing. This pilot connec-
tion must be plumbed to an unregulated ltered air source. The
purpose of this connection is to aid in low pressure differential
start-up and restart of the pump while providing a more accurate
pressure control. The pump will not function if this unregulated
air supply is not connected to the pilot valve port.
The pump is assembled at the factory using permanent synthetic
grease in the air drive moving parts.
Always bolt the pump to a substantially
solid surface using the slotted holes provided.
WARNING
AFL Pumps have a maximum sound level
of 87 dBA. Wear hearing protection while working
with or near the pump.
CAUTION
Unless otherwise noted, all air line accessories for the pump
air drive should have, at minimum, a 3/4" FNPT connection.
The tubing/piping used to connect the components should
have the maximum ID the pressure rating will allow. Reduc-
ing the size before the air inlet will reduce air pressure ow
and reduce ow rate of the pump.
NOTICE
The use of an air line lubricator is not required and is not
recommended. The oil in the air lubricator will cause the
factory installed grease to be purged from the pump. Once
an air lubricator is used the pump can never again be oper-
ated without an air lubricator.
NOTICE
An air line lter with a minimum 5 microns ltration rating must
be used on the supply line. If the air supply is not dry, a mist
separator must be used to remove moisture in the air line.
Parker Autoclave Engineers can supply a complete air control
package that includes a lter, air pressure regulator, air pres-
sure gauge and shutoff valve. Mist separators are also available.
Contact the factory for more details on these options.
The pump is designed to function from 15 psi to 150 psi
(1 to 10 bar) air input pressure.
Section 6.2
Liquid Section
All AFL series pumps have a high pressure liquid outlet port
located on the side of the pump head. The suction inlet port on
all AFL series pumps is positioned at the bottom of the head.
Inlet: A liquid lter with at least a 100 mesh size must be
installed before the suction port inlet to prevent damage to the
check valves and high pressure seals due to debris.
The tubing or piping should be made from a corrosion resistant
material and sized with a maximum ID to t the 1" pipe
connections.
Outlet: The outlet tubing ID must, at minimum, match the same
size of the pump check valve gland port. Refer to product litera-
ture for outlet connections details for each pump. Reducing out-
let tubing or connection will reduce output liquid ow capacity.
For best performance, a liquid supply reservoir should be
located higher than the inlet gland on the pump to create
a small pressure head. Be sure to make an air tight seal
between the reservoir and the pump inlet connection. The
connections between the reservoir and pump inlet should
not be reduced from the 1" FNPT connection size.
NOTICE
The high pressure tubing must be rated to at
least the maximum pump output pressure.
WARNING
Restricting ow at the liquid inlet will cause problems with
check valve performance and reduce output ow.
