INDUSTRIAL PUMP 8000 SERIES
Installation and Operation Manual
SHURflo offers various pump models for different applications. The
information outlined by this manual is general, and not specific to all 8000
Be certain the pumps' materials will be compatible with the
fluid being pumped. 8000 series pumps are intended for intermittent or
continuous duty when the proper operating criteria is met. Product Data
Sheets outlining specific thermal limits, load, flo
w curves, and other technical
information for a particular model are available. If unsure of the chemical
compatibility with a given elastomer or the motors intended design, please
call SHURflo for assistance.
CAUTION: "Intermittent Duty" is defined as; o
frequently started within a period of time that would cause the motor to
reach its maximum thermal limits. Once the maximum thermal limit is
obtained, the motor must be allowed to return to ambient temperature
before resuming operation.
CAUTION: DO NOT
use to pump flammable liquids. Never operate
the pump in an explosive environment. Arcing from the motor brushes,
switch or excessive heat from an improperly cycled motor may cause an
explosion.
CAUTION
: DO NOT assume fluid compatibility. I
f the fluid is improperly
matched to the pumps' elastomers, a leak may occur. Pumps used to
transfer hazardous or hot (max. temperature 170°F [76°C] Viton™
chemicals must be in a vented area to guard against the possibility of injury
due to harmful or explosive liquid/vapors.
CAUTION: DO NOT
operate the pump at pressures which cause the motor
to exceed the amperes rating indicated on the name plate.
models are equipped with thermal breakers to interrupt operation due to
excessive heat. Once the temperature of the motor is within proper limits it
will automatically reset, and the pump
will start operation without
vent electrical shock, disconnect power before initiating
any work. In the case of pump failure, the motor housing and/or the
pumped fluid may carry high voltage to components normally considered
safe.
PRESSURE SWITCH OPERATION (If Equipped)
The pressure
switch reacts to outlet pressure, and interrupts power at the
off pressure indicated on the pump label. When outlet pressure
drops below a predetermined limit (*typically 15-20 psi. [1-1.4 bar]
the shut-off pressure), the switch will
close and the pump operates until the
shut-off (high) pressure is achieved. The shut-
off pressure is set to factory
calibrated standards.
CAUTION:
Improper adjustment of the pressure switch setting, may cause
severe overload or premature failure. Refer
to SHURflo Service Bulletin
1031 for the adjustment procedure. Failures due to improper adjustment
of the pressure switch setting will not be covered under the limited
warranty.
If the plumbing is restrictive or the flow rate is very low, the pump may re-
pressurize the outlet faster than the fluid is being released, causing rapid
ON/OFF within 2 sec.). If the pump is subjected to rapid cycling
during normal operation, or for infrequent periods, damage may occur.
Applications which exhibit rap
id cycling should have restrictions in the outlet
minimized. If not feasible consider a SHURflo Accumulator or a SHURflo
"bypass" model pump.
BYPASS OPERATION (If Equipped*)
A bypass pump may be used in application that would normally induce
t/stop of the motor, and thereby create a potential for
overheating. Models equipped with an internal bypass are designed to pump
at high pressure while at low flow rates. Bypass models equipped with a
switch may operate for several seconds even though t
been closed off. Models equipped with a bypass only will continue to run until
The 8000 series pumps are self priming. Horizontal and vertical prime vary
depending on the fluid viscosity and pump confi

•
The pump should be located in an area that is dry and provides adequate
ventilation. If mounted within an enclosure, provisions to cool the motor
may be necessary. Heat sinks which attach to the motor are
SHURflo if increased heat dissipation is necessary.
CAUTION: DO NOT
locate the motor near low temperature plastics or
combustible material. The surface temperature of the motor may exceed
*250°F [120°C].
• The pump may be mounted in any posi
tion. However, if mounting the
pump vertically the pump head should be in the down position so that in the
unlikely event of a leak, fluid will not enter the motor.
• Secure the rubber feet with
#
8 hardware. DO NOT
doing so will reduce their ability to isolate vibration/noise.
PLUMBING
•
Use flexible high pressure tubing compatible with the fluid to connect the
inlet/outlet ports. Tubing should be either 3/8" or 1/2" [10 or 13 mm] I.D.,
and at least 18 in. [46 cm] length is suggested to mi
fitting/ports and reduce noise. Allow for the shortest possible tubing route
and avoid sharp bends that may kink over time.
•
Installation of a 50 mesh strainer is recommended to prevent foreign
debris from entering the system. Failure
s due to foreign debris is not
covered under the limited warranty.
NOTE:
Restrictions on the inlet may cause vacuum levels to reach the fluid
vapor pressure, causing cavitation, degassing, vapor lock and a loss
in performance. Inlet pressure must not exce
