2088 INDUSTRIAL SERIES PUMPS

SHURflo offers various pumps models for different applications. The information outlined by this manual is

general, and not specific to all 2088 series pumps. Be certain the pumps' materials will be compatible with the

fluid being pumped. 2088 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

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 wil operate until the shut-off (high) pressure is achieved.

The shut-off pressure is set to factory calibrated standards. See the motor label and Product Data Sheet for specific

pump specifications.

CAUTION: Improper adjustment of the pressure switch, 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 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 seconds). 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 considered a SHURflo Accumalator or a SHURflo

"bypass" model pump.

BYPASS OPERATION

A bypass pump may be used for applications that 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 outlet side has been

closed off. Contact SHURflo for information regarding bypass pumps.

• The 2088 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.

RETURN POLICY All Industrial pumps/products must be flushed of any chemical (ref. OSHA Section 1910.1200 (d)(e)(f)(g)(h)) and hazardous chemicals must be labeled/tagged before being *shipped to SHURflo for service or warranty consideration. SHURflo reserves the right to request a Material Safety Data Sheet from the returnee for any pump/product it deems necessary. SHURflo reserves the right to "disposition as scrap" pumps/products returned which contain unknown fluids.
