Description:
SL-11 series injectors are designed for
applications requiring large volumes of grease.
They are supplied with packings compatible with
synthetic and petroleum based greases. Available
only as a single unit with 1/2 NPT inlet, and 1/4
NPT outlet. The SL-11 injector incorporates a
hydraulic filler fitting for priming the feed line.
Output adjustment:
The SL-11 injectors output is adjusted with the
hex screw on top of the unit. A minimum output
of approx. .050 cu. in. is obtained when the
adjusting screw is turned clockwise, into the
injector, hand tight. To obtain the maximum
output of .50 cu. in., start at the minimum setting
and turn the screw counterclockwise 12 3/4
turns, out of the injector. Each turn of the screw
is equal to .043 cu. in. in output. When the
injector is adjusted to a half turn open or less,
output from the injector should be verified.
Disassembly Instructions:
1. Remove the adjustment adapter (item #3)
from the top of the injector. Remove the piston
assembly (item #8), spring (item #9), and spacer
(item #19) from inside the injector.
2. Remove the inlet adapter (item #18) from the
bottom of the injector. To remove the slide valve
assembly (item #11), turn injector over, with the
top pointing down. If the slide valve does not
fall out, it may be pushed out of the slide valve
packings (items #13) with a blunt object, being
careful not to scratch or cut the packings in the
slide valve body.
3. To remove the valve body (item #16):
a. If it sticks in the inlet adapter (item #18),
gently pry the valve body out of the inlet adapter
using a small round rod. Place the rod into a
hole in the side of the valve body and pry against
the face of the inlet adapter. Work one hole at a
time, working around the valve body until it is
freed.
