NOTICE:
Blackmer truck pumps must only be installed in systems
designed by qualified engineering personnel.
design must conform with all applicable regulations and
codes and provide warning of all system hazards.
PRE-INSTALLATION CLEANING
NOTICE:
New pumps contain residual test fluid and rust inhibitor.
If necessary, flush pump prior to use.
Foreign matter entering the pump WILL cause extensive
damage. The supply tank and piping MUST be cleaned and
flushed prior to pump installation and operation.
LOCATION AND PIPING
An improperly designed piping system or unit installation
WILL significantly reduce pump performance and life. The
following are piping system guidelines for pump installation.
1. To minimize intake losses, locate the pump as close as
possible to the source of supply.
2. Piping MUST be properly supported to prevent any piping
loads from being placed on the pump.
3. Intake piping and fittings MUST be at least as large in
diameter as the pump intake connection.
4. Minimize the number of intake line fittings (valves, elbows,
etc.) and piping turns or bends.
5. Install vacuum and pressure gauges in the ¼" NPT ports
located on the pump cylinder near the intake and
discharge flanges to check pump at start-up
6. Install a strainer in the inlet line to protect the pump from
foreign matter. Place the intake strainer to allow frequent
cleaning.
7. Intake and discharge piping MUST be free of all leaks.
TRUCK MOUNTING
The pump will operate satisfactorily in any position. Consult
Blackmer factory for vertical shaft mounts. The pump can be
bolted to the truck frame or on a saddle hung below the
frame, and MUST be adequately supported. Mounting the
pump with the cylinder feet down, or with the intake port up, is
recommended for thorough draining of the pump.
INSTALLATION
PUMP DRIVE
The pump may be driven by a power take-off through
System
universal joints. When using universal joints, a splined slip
joint, properly lubricated, must be used on the connecting
jackshaft to prevent end thrust on the pump shaft.
It is very important to install a proper drive line to avoid
excessive wear, vibration and noise see Fig. 2 and Table 1.

General guidelines to follow for proper pump drive:
1. DO NOT use Square slip joints.
2. Use the least number of jackshafts as is practical.
3. Use an even number of universal joints and a balanced
drive shaft for the high speed pumps.
4. The pump shaft and power take-off shaft must be parallel
in all respects. Use an angular level measuring device to
ensure the PTO and pump shaft are parallel to each
other. If necessary, the pump can be shimmed to correct
any misalignment. The PTO shaft coming off at the
transmission does not need to be perfectly horizontal as
long as the pump is shimmed to have its shaft parallel in
all respects to the PTO shaft.
5. The yokes of the universals at both ends of the jackshaft
must be parallel and in phase.
6. The maximum angle between the jackshaft and the pump
shaft is 15 degrees. Refer to Table 1.
Failure to follow any of these guidelines may result in a gallop
or uneven turning of the pump rotor, which will in turn cause a
surging vibration to the liquid stream and piping system.
Contact the supplier of the drive line components for specific
design assistance.

A drive shaft guard between the PTO
and pump must be provided to prevent
personal injury, property damage, or
death.
