Explosion hazard. Do not operate with rivets removed
from motor case. Explosion resulting in property damage,
personal injury or death can occur.
Case openings must be sealed to avoid explosion and to
maintain ignition protected rating.
APPLICATIONS
The Jabsco Rotary Vane pump is ideal for transferring diesel fuel.
The vectra rotor and vectra vanes are not affected by petroleum
products. It is self-priming with a suction lift of up to three feet and
can pump against a discharge head of up to thirty feet.
W A R N I N G
Explosion hazard. Do not pump volatile liquids with
a flash point below 100ºF (37.8ºC). Doing so can cause an
explosion or fire resulting in injury or death.
NOTE: No. 2 diesel fuel has a flash point of 125°F (52°C) [ASTM,
INSTALLATION
The pump must be mounted in a dry location – the motor is not
waterproof and must not be submerged. Selection of a cool venti-
lated location will generally extend pump motor life. The unit can
be mounted in any desired position. It is best to mount so that fluid
dripping from a loose port connection will not wet the motor. The
pump head may be mounted at 90 degree increments on the mo-
tor to allow mounting as needed.
Motor meets USCG Electrical Standards (Title 33, Chapter I, Part
183; Subpart I) and ISO 8846 Marine for ignition protection on
gasoline powered vessels. See warning note.

PLUMBING CONNECTIONS
Pump ports have external 1" (25mm) hose barb and internal 1/2"
(13mm) pipe threads.Use hose that does not kink when bent and
with sufficient wall thickness to prevent collapse when used on suc-
tion side of pump. Ideally, hoses should be routed so that some flu-
id will be retained in pump body to wet the rotor and vanes.Wetting
the rotor and vanes aids in priming. Use a strainer on the intake
hose if debris or solids are present in the fluid being pumped. All
hoses must have airtight connections to enable fast priming.

ELECTRICAL SPECIFICATION
Explosion hazard. If pump is operated in an area
containing flammable vapors, wire leads must be joined by
insulated mechanical locking connectors. Loose or inade-
quate wire connections can spark resulting in an explosion,
property damage, personal injury or death can occur.
Connect black wire to negative (–) terminal of battery. The orange
wire should run to a properly sized (see electrical specification)
overload protected switch or circuit breaker, with a wire from switch
or breaker to positive (+) terminal of battery. Electrical circuit must
be independent of all other accessories. A reversing switch may be
used to reverse pump for intermittent duty cycles. Preferred mo-
tor rotation is clockwise looking at shaft end of motor. To prolong
motor life, install pump so normal motor rotation is clockwise. Use
proper wire size as determined by wire table on this sheet.
