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

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.

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.
PAGE 3
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.

vapor lock and a loss in performance. Inlet pressure must not exceed 30 psi [2.1 bar] maximum. • If a check valve is installed in the plumbing it must have a cracking pressure of no more than 2 psi [.14 bar]. NOTE: SHURflo does not recommend the use of metal fittings or rigid pipe to plumb the inlet/outlet ports. Standard plastic male and female threaded fittings can be acquired at commercial plumbing supply stores.

• Improper duty cycle and/or rapid start & stop conditions may cause the internal thermal breaker (if equipped) to trip, or 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.

thermal devices may result in a motor failure, which will not be covered under the limited warranty. *The information outlined by this manual is general, and not specific to all 8000 series pumps. Contact the factory for a Product Data Sheet outlining technical information for a particular model.

SERVICE KITS Kits are readily available to repair standard 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.
