SHURFLO® LO-FLO 105 SERIES RV PUMPS

INSTALLATION MANUAL

SHURFLO Lo-Flo 105 Series RV pumps are rugged, lightweight, compact and provide the ability to self-prime and run dry.

Standard features include a pressure demand switch, built in 3/8” hose barb ports, ﬂexible mounting feet, splash proof motor,

and thermal protector. All with the security that comes with a UL Recognized Component.

INSTALLATION

SHURFLO Lo-Flo 105 Series RV pumps are self-priming and can be located up to 2.5

feet above the water level. Horizontal and vertical prime vary depending on the ﬂuid

viscosity and pump conﬁguration. The pump can be at the same level or below the

tank.

❚ The pump should be located in an area that is dry and properly ventilated to pre-

vent heat build-up.

❚ Use 50-mesh strainer minimum at the inlet side of the pump. Use ﬂexible hose on

inlet.

❚ The pump can be mounted in any position. However, if mounting the pump verti-

cally the pump head should be in the down position so that in the event of a leak,

ﬂuid will not enter the motor.

❚ 12 Volt pump must be provided with a 5-amp fuse.

❚ Recommended wire size is 16 gauge (1.3 mm) or larger wire as determined by volt-

age drop. Negative (-) must be connected to a known ground. Ground wire must be

the same (gauge/mm) as the positive.
