Installation Guidelines
Reference letters found in the following instructions,
refer to Typical Installation diagram provided on page 7.
A ball valve must be installed upstream of the regu-
lator (G).
The fluid outlet line (A), fluid inlet line (L) and air
inlet line (M) must be flexible (such as a hose).
NOTE: To prevent damage to the pump, remove sedi-
ment from the bottom of the container before installing a
pump on an existing container.
Stationary Mounting Layout
Plan the layout for easy operator access to the pump air
controls, sufficient room to change drums and a secure
platform.
Pump Mounting
1. Install bung adapter (K) into bung mount/bracket/or
drum cover.
2. Install pump (B) into bung adapter (K).
Installing Outlet Hose (F
IG. 3)
1. Connect the swivel adapter (aa) to the pump fluid
outlet. Tighten securely and torque as recom-
mended below:
For NPT models: 1 to 1-1/2 turns past hand
tight.
For BSPT models: 1-1/2 to 2 turns past hand
tight.
2. Connect the fluid hose (A) to the swivel adapter
(aa).
3. Connect a suitable dispensing valve or extra hose to
the 6-ft hose.
The maximum working pressure of each pump in
your system may not be the same. To reduce the risk
of over-pressurizing any part of your system, which
may result in component rupture, fire or explosion
and cause serious bodily injury, be sure you know
the maximum working pressure rating of each pump
and its connected components.
Never exceed the maximum working pressure of
the lowest rated component connected to a partic-
ular pump.
Be sure you know the maximum working pressure
of each component.
Do not exceed the maximum pump cycle rate.
Regulate air pressure to prevent over pressuriza-
tion at fluid section of the pump.
Regulate air pressure to the pump so that no fluid
line component or accessory is over pressurized.
