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 suction tank and piping MUST be cleaned and
flushed prior to pump installation and operation.
LOCATION AND PIPING
An improperly designed piping system or improper unit
installation WILL significantly reduce pump performance and
life. Blackmer recommends the following piping system layout
and unit installation.
1. To minimize intake losses, locate the pump as close as
possible to the source of supply.
2. Intake piping and fittings MUST be at least as large in
diameter as the pump intake connection.
3. Minimize the number of intake line fittings (valves, elbows,
etc.) and piping turns or bends.
4. It is recommended an intake strainer be installed at least
24" (0.6m) from the pump intake. For viscosities less than
1000 SSU the strainer should have a net open area of at
least four times the area of the intake pipe. For viscosities
greater than 1000 SSU consult the strainer manufacturer
instructions. Strainers must be cleaned regularly to avoid
pump starvation.
5. Intake and discharge piping MUST be free of all leaks.
6. Expansion joints, placed at least 36" (0.9m) from the
pump, will compensate for expansion and contraction of
the pipes. Contact the flexible connector/hose
manufacturer for required maintenance/care and design
assistance in their use.
7. Install vacuum and pressure gauges in the 1/4" NPT ports
provided in the pump cylinder to check pump at start up.
8. ALL piping and fittings MUST be properly supported to
prevent any piping loads from being placed on the pump.
9. Check alignment of pipes to pump to avoid strains which
might later cause misalignment. See Figure 1. Unbolt
flanges or break union joints. Pipes should not spring
away or drop down. After pump has been in operation for
a week or two, completely recheck alignment.
Figure 1
10. When pumping liquids at elevated temperature, provisions
should be made to compensate for expansion and
contraction of the pipes, especially when long pipe lines
are necessary. Steel pipe expands approximately 3/4”
(1.9 cm) per 100 feet (30.49 m) per 100°F (37.8°C) rise in
temperature.
CHECK VALVES
The use of check valves or foot valves in the supply tank is not
recommended with self-priming, positive displacement pumps.
If the possibility of liquid backflow exists when the pump is off,
a check valve in the pump discharge piping is recommended
because the pump can motor in the reverse rotation and create
undue stress on all attached components. Never start a pump
when it is rotating in the reverse rotation as the added starting
torque can damage the pump and related equipment.
PUMP MOUNTING
Permanently mount the unit by securing the base plate with
adequately sized anchor bolts to a level concrete floor following
recommended industry standards. A solid foundation will
reduce system noise and vibration, and will improve pump
performance. Refer to ANSI/HI standards or a suitable pump
handbook for information on typical pump mounting and
foundations. BOLT

PRE-START UP CHECK LIST
1. Check the alignment of the pipes to the pump. Pipes
should be supported so that they do not spring away or
drop down when pump flanges or union joints are
disconnected.
2. Inspect complete piping system to ensure all valves and
fittings are in their start up or operation positions.
3. Ensure all electrical connections are correct and tight.
4. Jog the pump motor to ensure free and CLOCKWISE
pump rotation, as viewed from the fan end of the motor.
START UP PROCEDURES
NOTICE:
CONSULT THE "TROUBLESHOOTING" SECTION OF THIS
MANUAL IF DIFFICULTIES ARE EXPERIENCED DURING
START UP.
1. Start the motor. Priming should occur within one minute.
2. Check the vacuum and pressure gauges installed on the
pump to ensure the pump is operating within the
acceptable parameters. Record the gauge readings in the
"Initial Pump Start Up Information" section.
3. If possible, check the flow rate to ensure the pump is
operating within expected parameters.
4. Inspect piping, fittings and associated system equipment
for leaks, noise, vibration and overheating.
5. If equipped, check the pressure relief setting of the pump
relief valve by gradually closing a valve in the discharge
line momentarily and noting the reading on the pressure
gauge. This pressure reading should be 10-20 psi (.96 –
1.4 bar) higher than the maximum system operating
pressure. DO NOT run the pump for more than 15
seconds with the discharge valve completely closed. If
adjustments need to be made, refer to "Relief Valve
Setting and Adjustment."
PUMP ROTATION
The pump models described in this manual are designed as
RIGHT HAND pumps ONLY, with CLOCKWISE rotation. When
viewing the pump from the drive end (motor end), the pump
intake port must always be on the right, and the discharge port
on the left.
REVERSE ROTATION NOTICE:
MAGNETIC COUPLED PUMPS SHOULD BE OPERATED IN
REVERSE ROTATION FOR NO MORE THAN 10 MINUTES,
AND ONLY WHEN A SEPARATE PRESSURE RELIEF
VALVE IS INSTALLED TO PROTECT THE PUMP FROM
EXCESSIVE PRESSURE.
It may be desirable to operate the pump in reverse rotation for
system maintenance. The pump will operate satisfactorily for a
LIMITED time; at a reduced performance level.
FLUSHING THE PUMP NOTICE:
IF FLUSHING FLUID IS TO BE LEFT IN THE PUMP FOR AN
EXTENDED TIME, IT MUST BE A LUBRICATING, NON-
CORROSIVE FLUID. IF A CORROSIVE OR NON-
LUBRICATING FLUID IS USED, IT MUST BE FLUSHED
FROM THE PUMP IMMEDIATELY.
1. To flush the pump, run the pump with the discharge valve
open and the intake valve closed. Bleed air into the pump
through the intake gauge plug hole or through a larger
auxiliary fitting in the intake piping. Pump air for 30 second
intervals to clean out most of the pumpage.
2. Run a system compatible flushing fluid through the pump
for one minute to clear out the remainder of the original
pumpage.
3. To remove the flushing fluid, follow step 1 above.
On SMVP models any remaining fluid in the pump can be
drained from the cylinder through the drain plugs (73A).
NOTICE:
AFTER FLUSHING THE PUMP SOME RESIDUAL FLUID
WILL REMAIN IN THE PUMP AND PIPING.
NOTICE:
PROPERLY DISPOSE OF ALL WASTE FLUIDS IN
ACCORDANCE WITH THE APPROPRIATE STANDARDS
AND REGULATIONS.

OPERATION
PUMP RELIEF VALVE
NOTICE:
A PUMP RELIEF VALVE AND / OR AN EXTERNAL BYPASS
VALVE MUST BE INSTALLED IN THE SYSTEM TO
PROTECT THE PUMP FROM EXCESSIVE PRESSURE.
The SMVP15B and SMVP30B pump models are offered with
an optional pump relief valve assembly that bolts onto the
pump cylinder. Blackmer STRONGLY RECOMMENDS the
installation of the optional relief valve to protect the pump from
excessive pressure, and a separate system pressure control
valve to protect the system from excessive pressure.
The MVP15B, MVP20B, and MVP30B pump models come
equipped with an internal relief valve.
NOTICE:
THE PUMP RELIEF VALVE IS DESIGNED TO PROTECT
THE PUMP FROM EXCESSIVE PRESSURE AND MUST
NOT BE USED AS A SYSTEM PRESSURE CONTROL
VALVE.
Pumping volatile liquids under suction lift may cause cavitation.
Partial closing of the discharge valve WILL result in internal
relief valve chatter and is NOT recommended. For these
applications, install an external system pressure control valve,
and any necessary bypass piping, back to the storage tank.
A system pressure control valve is also recommended when
operating for extended periods (more than 1 minute) against a
closed discharge valve.
RELIEF VALVE SETTING AND ADJUSTMENT
The factory relief valve pressure setting is marked on a metal
tag attached to the valve body. It is recommended the relief
valve be set at least 10-20 psi (.69-1.4 bar) higher than the
operating pressure or the system pressure control valve
setting.
DO NOT remove the R /V Cap OR adjust the relief valve
pressure setting while the pump is in operation.
Hazardous pressure
can cause personal
injury or property
damage
INCORRECT SETTINGS OF THE
PRESSURE RELIEF VALVE CAN CAUSE
PUMP COMPONENT FAILURE,
PERSONAL INJURY AND PROPERTY
DAMAGE
Hazardous or toxic
fluids can cause
serious injury.
