Installation and Operation Manual

• 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 temperature
of the motor may exceed 250°F [120°C]. Refer to the pumps 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
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.
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] maximum.
• 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].
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 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: All 115
VAC and 230 VAC pump motors and systems, MUST be ground per local and state electrical
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.
• 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.
