Always read the most current version of this manual before performing any work on or around this pump.
The most current version of this manual is freely available on the web at www. blackmer.com
Blackmer pumps are specifically configured for your unique application conditions. Those application
conditions and the details of the pump configuration were documented during the ordering process. Keep
that information available in a safe place, as it may be needed when troubleshooting pump problems or
when ordering spare parts or repairs.
Blackmer Gear Pumps are covered by one or more of the following patents: U.S.Patent Nos. 7549205,

Cautions—Read First!
CAUTION: Only personnel who are familiar with the
operation and repair of mechanical products should perform
the necessary maintenance. You must familiarize yourself
with the entire contents of this manual prior to operating
and/or performing any maintenance.
CAUTION: When selecting a G Series pump for an
application, you must first ensure that the pump components
are compatible with the process media.
CAUTION: Prior to startup, review and understand end-
clearance adjustments. Following these guidelines will
ensure proper end-clearance adjustment avoiding
interference between the gears and head. Interference may
cause heat generation and premature wear.
CAUTION: Do not operate this pump in excess of its rated
capacity, pressure, speed and temperature.
CAUTION: Before any maintenance and repair is
attempted, disconnect the drive.
CAUTION: Before any maintenance or repair is attempted,
bleed all pressure from the pump through the suction or
discharge lines.
CAUTION: Do not remove any pressure-containing
components during pump operation.
CAUTION: All G Series pumps contain residual hydraulic oil
from the factory production test. Hypar-FG 15 food-grade oil
is the standard production test fluid, but any certified
performance testing may be done on a non-food grade oil,
such as Unilube 32 (ISO 32) or Unilube 100 (ISO 100).
Determine if this is compatible with the fluid you are
pumping. If the fluid is incompatible, then the pump must be
fully flushed prior to use.
CAUTION: When pumping fluids at elevated temperatures,
care should be taken to gradually increase temperature.
Rapid temperature increase can damage internal
components.
CAUTION: Ensure that the pump has cooled to a safe
temperature, especially pumps equipped with a jacket,
before any maintenance or repair is attempted.
CAUTION: When pumping fluids at elevated temperatures
the piping may expand, resulting in excessive stress on the
pump. This can cause pump failure. Care must be taken
when considering pipe design to avoid damage from thermal
expansion.
CAUTION: Do not run the pump dry. This can cause
damage to internal components and generate heat, creating
a hazardous condition for volatile fluids.
CAUTION: Prevention of static sparking –If static sparking
occurs, fire or explosion could result. Pump, valves and
containers must be grounded to a proper grounding point
when handling flammable fluids and whenever discharge of
static electricity is a hazard.
CAUTION: The packing in a packed pump is designed to
leak. Therefore, when pumping hazardous liquids, a
mechanical seal is recommended to minimize any potential
source of leakage that could result in a hazardous condition.
CAUTION: Do not adjust packing while pump is in operation.
CAUTION: All inlet and discharge plumbing should be clean
and free from foreign material prior to startup of pump.
CAUTION: Keep hands and fingers away from any pump
opening while the pump is connected to the drive.
CAUTION: When connecting to an electric motor, follow all
safety recommendations provided by the motor
manufacturer.
WARNING: In any positive-displacement pump system, a
reliable pressure-protection device must be used in the
discharge piping to avoid a dangerous pressure increase,
which could cause the pump or any component in the
discharge piping to burst and can lead to serious injury. A
pump-mounted integral relief valve is not intended to be
used in this manner.
WARNING: During operation the pump surface temperature
can exceed 140°F (60°C). Allow for proper cooling before
any handling.
CAUTION: Never remove safety guards from shafts,
couplings, V-belts or pulleys during operation. Doing so
could result in injury.
CAUTION: When pumping high-temperature fluids, avoid
contact with the pump. Serious injury could occur.
CAUTION: Do not wear loose or dangling clothing or jewelry
near the equipment. These items could become caught in
the equipment and cause injury.
CAUTION: Before any maintenance or repair is attempted,
ensure that the pump has been thoroughly flushed of any
hazardous fluids. Review the Material Safety Data Sheet
(MSDS) applicable to the fluid for proper handling.
