Shurflo 2088-554-144 Installation Manual

2088 INDUSTRIAL SERIES PUMPS

Installation and Operation Manual

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.[
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 (
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 pum ps.

MOUNTING

911-396 Rev. J 12/01 Page: 1 of 4

• 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.

CAUTION: DO NOT locate the motor near low temperature plastics or combustible materials. The surface tem perature

of the motor may exceed 250°F [120°C]. Refer to the pum ps Product Data Sheet.

• 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 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

• Flexible high pressure tubing compatible with the fluid should be used to connect the inlet/outlet ports. Tubing should

be either
fitting/ports and reduce noise. Allow for the shortest possible tubing route and avoid sharp bends that may kink over
time.

NOTE:Restrictions on the inlet may cause vacuum levels to reach the fluid vapor pressure, causing cavitation,

• 1/2" Male threaded models: Are intended to be used with SHURflo Swivel Barb Fittings which seal with an

internal taper when hand tightened. Standard 1/2" NPT fittings may be used when tightened to a maximum
torque of 3.7 ft\Lb (45 in\Lb) [5 Nm].

/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

degassing, vapor lock and a loss in performance. Inlet pressure must not exceed 30 psi.[2.1 bar] maximum.

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. SHURflo also
distributes Swivel Barb Fittings, and special fitting through it' s dealers (Form

#

07-010-0011).

CAUTION: Sealers and Teflon tape may act as lubricant causing cracked housings or stripped threads due to over-

tightening. Care should be used when applying sealers. Sealers may enter the pump inhibiting valve
action, causing no prime or no shut-off. Failures due to foreign debris is not covered under warranty.

• Installation of a 50 mesh strainer is recommended to prevent foreign debris from entering the pump.

• If a check valve is installed in the plumbing, it must have a cracking pressure of no more than 2 psi [.14 bar].

ELECTRICAL

CAUTION: Electrical wiring should be performed by a qualified electrician, in accordance with all local

electrical codes.

• The pump should be on a dedicated (individual) circuit, controlled with a double pole switch (U.L./C-UL certified)

rated at or above the fuse ampere indicated by the pum p 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: All 115

codes.

• Improper duty cycle and/or rapid start & stop conditons 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.

VAC and 230 VAC pump motors and systems, MUST be ground per local and state electrical

• For the pump to meet U.L./C-UL requirements the circuit MUST be protected with a slow-blow fuse (U.L./C-UL

certified) or equivalent circuit breaker as indicated on the motor label. Use an approved wire of the size specified or
heavier.
