Flexible high pressure tubing compatible with the fluid
should be used to connect the inlet/outlet ports. Tubing
should be 1/2” [13 mm] I.D. and at least an 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.
Restrictions on the inlet may cause vacuum levels to
reach the fluid vapor pressure, causing cavitation, degas-
sing, vapor lock, noise, and a loss in performance. Inlet
pressure must not exceed 30 psi [2.1 bar] maximum.
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 com-
mercial plumbing supply stores.
also distributes
swivel barb fittings and special fittings through its dealers.
1/2” Female NPT models
: In some cases, the ports may require
a suitable thread sealer applied sparingly. DO NOT over-tighten,
max. torque 3.7 ft. lbs. [45 in. lbs. (5 Nm)].
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.lbs [45 in.lbs (5 Nm)].
Sealers and Teflon tape may act as a 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 are 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 crack-
ing pressure of no more than 2 psi (.14 bar).
The pressure switch reacts to outlet pressure and inter-
rupts 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 will operate until the shut-off (high) pressure is
achieved. The shut-off pressure is set to factory calibrated
standards. See the motor label for specific pump specifi-
cations.
Improper adjustment of the pressure switch may cause
severe overload or premature failure. 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, damage may occur. Applications which
exhibit rapid cycling should have restrictions in the outlet
minimized.
The 5059 series pumps are self priming. Horizontal and
vertical prime vary depending on the fluid viscosity and
pump configuration.
The pump should be located in an area that is dry and
provides adequate ventilation. If mounted within an enclo-
sure, provisions to cool the motor may be necessary. If
increased heat dissipation is necessary, motor mount-
able heat sinks are available from
DO NOT locate the motor near low temperature plastics
or combustible materials. The surface temperature of the
motor may exceed 250°F [120°C].
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 com-
press the feet: doing so will reduce their ability to isolate
vibration/noise.

Bypass Operation
A bypass pump may be used for applications that nor-
mally induce frequent start/stop of the motor, and thereby
create a potential for overheating. Models equipped with closed off. Contact
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
