94-053-00 Carbonator Pump
Installation & Operation Manual
SHURflo offers various pump models for
different applications. The information
outlined by this manual is specific to
carbonator applications. The 8000 series
pumps are intended for intermittent duty.
These pumps feature a DC motor
(rectified to AC) of low amp draw, which
allow wide voltage fluctuations without
burning-out
CAUTION: This pump has been evaluated for use with water only!
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. This pump is designed for a duty cycle
of 30% on, 70% off. Once the maximum thermal limit is obtained, the motor must be allowed to return
to ambient temperature before resuming operation.
CAUTION: Never operate the pump in an explosive environment. Never pump flammable or explosive
liquids! Arcing from the motor brushes, switch or excessive heat from an improperly cycled motor may
cause an explosion.
CAUTION: DO NOT operate the pump at pressures, which cause the motor to exceed the
amperes rating indicated on the nameplate. This pump is equipped with a thermal breaker 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. This
pump is also protected by a fuse. This is a one-time fuse that must be changed by a qualified
electrician or sent back to SHURflo for replacement.
CAUTION: Risk of electric shock-this pump is supplied with a grounding conductor and
grounding type attachment plug. To reduce the risk of electric shock, be certain that it is
connected only to a properly grounded, grounding type receptacle.
MOUNTING
•The 8000 series pumps are self priming.
•The pump may be mounted in any position. However, it is not recommended mounting the
pump vertically in the unlikely event of a leak, fluid will enter the motor.
•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.
•Secure the rubber feet with #8 hardware. DO NOT compress the feet, doing so will reduce their
ability to isolate vibration/noise.

PLUMBING
•Snap-Lock Ports:The slide fittings are open when the slide is moved out toward the end of the
pump head. Fittings should be inserted flush against housing port before the slide is moved to the
locked position. Fittings of Nylon or Polypropylene are available in various sizes.
•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.
•Provision should be made to avoid high municipal inlet pressures. A regulator should be used to
maintain an inlet pressure of 30 PSI [2.1 bar].
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 exceed 30 psi
[2.1 bar]
If a check valve is installed in the plumbing it must have a cracking pressure of no more than 2 psi
[.14 bar].
CAUTION: After installation, system should be completely flushed and sanitized. Use a sanitizer
suitable for food service equipment. If a sanitizer is not available, use one cap of household bleach
to one gallon of clean water.
ELECTRICAL
CAUTION: a qualified electrician, in accordance with all local electrical codes should perform
electrical wiring.
•Improper duty cycle and/or rapid start & stop conditions may cause the internal thermal
breaker (if equipped) to trip, or the fuse to blow. This can result in premature motor failure
due to excessive heat. Refer to the pumps Product Data Sheet.
•The pump should be on a dedicated (individual) circuit, controlled with a double pole switch
(UL/C-UL certified) rated at or above the fuse ampere indicated by the pump motor label.
Depending on distance of the power source from the pump and ampere load on the circuit, wire
may need to be heavier than indicated by the chart.
CAUTION: the pump motors and systems, MUST be ground per local and state electrical codes.
•For the pump to meet UL/C-UL requirements the circuit MUST be protected with a slow-blow
fuse (UL/C-UL certified) or equivalent circuit breaker as indicated on the motor label. Use an
approved wire of the size specified or heavier.
CAUTION: Circuit protection is dependent on the individual application requirements. Failure to
provide proper overload / thermal devices may result in a motor failure, which will not be covered
under the limited warranty.
SERVICE KITS
Kits are readily available to repair the 8000 series pumps. Repair kits include simple illustrated
instructions allowing easy installation. To insure that the correct kit is received the model
numbered and all name plate data must be included with the order. Contact a SHURflo distributor
or SHURflo directly to order the necessary repair kit.

TROUBLE-SHOOTING
PUMP WILL NOT START- check for:
üFuse or breaker
üFor correct voltage (±10%) and electrical
connections
üPressure switch operation and correct voltage
at switch or motor wires (as equipped).
üRectifier or motor for open or grounded circuit
üFor locked drive assembly
WILL NOT PRIME (No discharge/motor runs) - check for:
üOut of product
üStrainer for debris
üInlet tubing/plumbing; severe vacuum leak
üInlet/Outlet tube severely restricted (kinked)
üDebris in pump inlet/outlet valves

üDoes the mounting surface multiply noise
(flexible)
üIs the pump plumbed with rigid pipe causing noise to
