TECHNICAL DATA
HOSE COMPRESSION
PUMP DATA
Maximum Operating Temperature
Maximum Operating Pressure
Hose Inserts
A determining factor in hose life is correct compression.
Proper shimming of the shoes will optimize hose life. Shims
are inserted between the rotor and the shoe. The number of
shims used depends mainly on the pump discharge pressure.
176oF (80oC)
217.5 psi (15 bar)
Stainless Steel (Std.)
PPH or PVDF (Opt.)
Pumps are factory adjusted to run at operating discharge
pressures of up to 72.5 psi (5 bar) without damage to the
hose. For operation at higher pressure, one or more shims
may be inserted under the shoes. See Shimming Table below.
HOSE CHARACTERISTICS
NOTICE:
THERE MUST BE THE SAME NUMBER OF SHIMS
UNDER EACH SHOE.
Pumping is carried out by repeated compression and release
of a specially designed elastomeric hose. Under normal
operating conditions, the pumped fluid is in contact only with
the hose and the inserts and must be compatible with them.
SHIMMING TABLE

Three grades of elastomeric hose are available:

This pumping principle is especially suited for abrasive
products. During the compression phase, the abrasive
particles are pushed against the wall of the hose without
damaging it. The particles are then released back into the
fluid after the pump shoe passes. NOTE: The particle size
MUST not exceed 15% of the hose inner diameter.

PIPING
BLACKMER HOSE PUMPS MUST ONLY BE INSTALLED IN
SYSTEMS DESIGNED BY QUALIFIED ENGINEERING
PERSONNEL. SYSTEM DESIGN MUST CONFORM WITH ALL
APPLICABLE REGULATIONS AND CODES AND PROVIDE
WARNING OF ALL SYSTEM HAZARDS.
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. The inlet pipe must be:
a. as short as possible.
HANDLING THE PUMP
ALWAYS USE A LIFTING DEVICE
b. the largest diameter possible.

ELECTRICAL POWER SUPPLY
Install, ground and wire to local and
National Electrical Code requirements.
PUMP LOCATION
Install an all-leg disconnect switch near
the unit motor.
Hazardous voltage.
Can shock, burn
or cause death.
Provide adequate space around the pump for service and
maintenance. Also, provide adequate space in piping system
for replacement of the hose. The distance between the pump
porting and the nearest obstacle should allow for removal of
the hose. Refer to Figure 2 and the corresponding chart to
determine the proper distances.
Disconnect and lockout electrical power
before installation or service.
Electrical supply MUST match motor nameplate
specifications.
Min.“A”
Motors equipped with thermal protection automatically
disconnect motor electrical circuit when overload exists.
Motor can start unexpectedly and without warning.
GENERAL INSTALLATION
1. Inspect piping and supports to ensure no piping loads are
being placed on the pump flanges.
2. Inspect complete piping system to ensure all valves and
fittings are in their start up or operation positions.
Figure 2 - Pump Spacing
3. Ensure all electrical connections are correct and secure.

PERCENTAGE OF SOLIDS
EXTENDED STORAGE
If the pump is to remain in storage for more than 3 months, it
is recommended the hose or the shoes be removed. If you do
not remove the hose during storage, let the pump run for a
minimum of 5 minutes once a week.
If the fluid being pumped is loaded with particles, it is
recommended to make the upper port of the pump the inlet. It
will be easier to remove the sediment formed by settling out of
particles contained in the liquid. Restarting the pump will be
easier and resistance to the movement of the pump shoes will
be reduced. NOTE: The particle size MUST not exceed 15%
of the hose inner diameter.

WARNING:
CONSULT THE "PUMP TROUBLESHOOTING" SECTION OF
THIS MANUAL IF DIFFICULTIES DURING START UP ARE
EXPERIENCED.
NEVER WEAR LOOSE CLOTHING WHILE OPERATING PUMP.
OPERATING PRINCIPLE
OPERATING PRECAUTIONS
Pumping is carried out by repeated compression and release
of a specially designed elastomeric hose. Two shoes located
at 180° on a central wheel tightly press the hose against the
pump body. The wheel rotation causes the displacement of the
product inside the hose. Therefore, the flow is pulsed. The
pump body is filled with a glycerin-based lubricant to ease the
sliding of the shoes and to prevent overheating. See Figure 3.
HOSE IS UNDER PRESSURE DURING
OPERATION. A HOSE BURST CAN
CAUSE PERSONAL INJURY OR
PROPERTY DAMAGE.
Hazardous pressure
can cause
personal injury or
property damage.
If pump hose bursts, the following may occur:
1. The casing may fill up with the pumped fluids.
Step A
2. The pumped fluid under pressure may flow out through the
vent.
Step B
3. If the pump is full of liquid (“loaded”), all fluid may drain
from the inlet line.
Step C
4. If the discharge line is under pressure, it may exhaust into
the pump.
NOTICE:
WHEN DRAINING THE PUMP CASING FOLLOWING A
HOSE BURST USE CARE NOT TO CONTAMINATE THE
PUMP LUBRICANT WITH THE PUMPED FLUID. IF
NECESSARY, REPLACE THE CONTAMINATED
LUBRICANT WITH NEW LUBRICANT.

Hose Cleaning and Replacement
Lubrication
Some fluids pumped may require cleaning of the hose after
each operation in order to avoid the hardening of the fluid
inside the hose. The hose can be cleaned easily with water or
a cleaning agent. Make sure that the cleaning agent is
compatible with the hose material and the fluid being pumped.
The hose is lubricated with a special glycerin-based lubricant.
To maintain proper hose life and durability always use genuine
Blackmer lubricant.
It is recommended the lubricant be changed:
Under proper service and installation conditions, the service
life of the hose may be up to 2000 hours. Depending upon the
product pumped, operating pressure and speed, the hose may
need more frequent replacement. Careful monitoring of the
hose is recommended so that it can be replaced prior to
failure. For hose removal and replacement instructions see
“Hose Removal” and “Hose Assembly” sections.
a. After each hose burst.
b. Whenever the hose is being replaced during normal
preventative maintenance.
c. After 2000 hours of operation.
It is recommended to replace the hose as part of preventative
maintenance.The hose is lubricated with a special glycerinbased lubricant. To maintain proper hose life and durability
always use genuine Blackmer lubricant.

During an extended shutdown period, one of
the shoes may have remained out of lubricant.
If shoe is no longer lubricated, there will be
an increased starting resistance.
Remove the hose and reassemble (see “Hose Removal”).
DO NOT force the pump to start - if the motor has excessive
power, there is strong risk of damaging the hose or reducer.
Some sediments or foreign matter may remain
in the hose, thus jamming the pump.
Reverse direction of rotation of the pump or remove the hose.
The inlet or discharge valve is partially closed.
Open inlet or discharge valve fully.
Air leaks in the inlet piping.
Check inlet piping for leaks.
Shimming is insufficient.
Adjust shimming of shoes and add shims if necessary
Refer to “Shimming Table” and “Shim Installation” sections.
The product pumped is too viscous.
High head loss at inlet.
Check inlet line (see “Piping”). Install a Blackmer vacuum
assist system.
Pump Hose is damaged.
Replace pump hose. Refer to “Hose Removal & Assembly.”
The lubricant is not adequate.
Drain pump casing. Use only Blackmer recommended
lubricant. Refer to “Lubrication” section.
The lubricant is dirty or old.
Drain pump body and replace with new lubricant.
The lubricant level is too low.
Add lubricant. Refer to “Lubrication” section for proper amount.
Temperature of fluid pumped is too high.
Check the maximum allowable temperature of the fluids
pumped with the materials of the pump hose.
Overshimming of the shoes.
Check the shimming under shoes and remove as necessary.
Refer to “Shim Installation” section and “Shimming Table.”
The pump speed is too high.
Reduce pump speed.
The Lubricant is not adequate.
Drain pump body. Use only Blackmer recommended
lubricant. Refer to “Lubrication” section.
Chemical incompatibility between hose
and the fluid being pumped.
Check the chemical compatibility of hose and fluid pumped.
Replace hose with proper compatibility.
The temperature of fluid pumped is too high.
Check maximum allowable temperature of pump hose.
The discharge pressure is too high.
Check maximum allowable discharge pressure of pump.
Minimize the head losses at discharge.
Inadequate shimming of the shoes.
Check shimming and adjust to pump operating conditions.
Refer to “Shimming Table” and “Shim Installation” sections.
The speed of the pump is too high.
Reduce pump speed.
Not enough lubricant.
Check level of lubricant and adjust as required (“Lubrication”).
Overshimming of shoes.
Check shims under shoes and adjust as required.
Refer to “Shimming Table” and “Shim Installation” sections.
Foreign matter or fluid sediments in hose.
Reverse the direction of pump rotation (inlet side up).
