Product Manual

gallon (420 lb) drums.
These pumps may be
installed as follows:
a. Attach the 2” bung
adapter, P/N 22157
(item A, fig 2), to the
2” opening at the top
of the drum.
b. Slide the pump into
the bung adapter
previously installed in
step #1 above.
c. Tighten the wing nut, item B, fig. 2, on bung
adapter to secure the pump at the desired
height.
2.) Universal “Stub” Pumps, fig. 3. Stub pumps may
be fitted with a 1” NPTM extension pipe and foot
valve, P/N 950002 to adapt to most any tank
situation (use 1
1
⁄2” in the case of high flow
pump, P/N 21300 with 1
1
⁄2”foot valve, P/N
950047). Alternatively,
these pumps may be
wall mounted with the
use of an available
wall mounting bracket,
P/N 22242 or P/N
22243, fig. 4.
a. Determine length of
extension pipe
required to reach
bottom of tank by
using the extension
pipe data chart below:
b. Attach extension pipe to stub pump taking care
to use a thread sealant on both ends of pipe as
it is threaded into the pump and foot valve, fig. 3.
c. Attach bung adapter
to 2” tank opening, fig.
5, item A
d. Slide the assembled
pump into bung
adapter and tighten
wing nut, fig. 5, item
B, to secure pump at
the desired height.
e.) Air Supply:
Attach the male portion of a 1/4” (use 3/8” fitting
for pump models 21200 and 21300) air quick
coupler at the air inlet
of the pump or air
filter/regulator (item A,
fig. 6). This allows a
quick and easy
method to disconnect
the air supply when
the pump is being
moved or not in use.
It is important to disconnect or shut off supply air to
the pump when left unattended, this prevents the
possibility of the pump emptying the fluid container
in case of a plumbing leak or catastrophic product
line failure.
