Shure 8000 User Manual

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 series pumps. 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, flow 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; operated and/or 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. If 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™ only) 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. Various pump 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

warning.

CAUTION: To prevent 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 preset shut-off pressure indicated on the pump label.
When outlet pressure drops below a predetermined limit (*typically
15-20 psi. [1-1.4 bar] less than 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 cycling (*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 rapid
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 frequent start/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 the discharge side has been closed off.
Models equipped with a bypass only will continue to run until
power is turned OFF.

MOUNTING

• The 8000 series pumps are self priming. Horizontal and vertical
prime vary depending on the fluid viscosity and pump
configuration. Refer to the pumps Product Data Sheet.

• 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 available from 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 position. 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 compress the
feet, 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 minimize stress on
the 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. Failures 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,
