Product Information :

The Jabsco 18685-0000 is a bronze rotary/sliding vane pump with a Nitrile Lip Type seal, 1/2 Inch NPT Female and 1 Inch Hose Barb Ports, coupled to a 1/8 Horsepower, 3450 RPM, 115 Volts, 60HZ Motor, with a 6 foot Cord and 3 Prong Grounded Plug. The Jabsco rotary vane pump is ideal for pumping light oil or transferring diesel fuel. The rotor and vanes are not affected by petroleum products. It is dry, self-priming with a suction lift of up to five feet and can pump against a discharge head of up to twenty feet. The motor is rated for continuous duty in applications with a total system head no greater than twenty feet and when pumping liquids with a similar viscosity to diesel fuel. When pumping light oils, the duty cycle should be no longer than thirty minutes. Rotary Vane pumps must NOT be run dry, as the pumped liquid is the lubricant for the rotor and vanes. Observe the outlet and shut off pump as soon as liquid stops flowing. The pump cannot run against a closed outlet as encountered when using a garden hose type shut-off nozzle. Pressure for normal operation should not exceed 20 feet of head (8.7 psi). Excessive pressures will cause motor to overheat tripping the thermal overload protector. Temperature of pumped liquid may range from 45 degrees-165 degrees F (7 degrees-74 degrees C). When pumping engine oil, run engine long enough to heat oil to about 150 degrees F (66 degrees C).

This pump can pump Diesel fuel BUT do not pump volatile liquids with a flash point below 100 degrees F .

This is a Continuously rated duty, AC diesel or light oil transfer pump. This 115V AC vane pump can be used as a portable pump or mounted permanently in pumping system. It can be mounted on any flat surface. However, it is advisable to mount it so the motor shaft remains horizontal. The pump head may be rotated on the motor 180 degrees to accommodate plumbing connections as needed or to change the direction of flow. Wetting the rotor and vanes aids in priming. Use a strainer on the intake hose if trash or solids are present in the fluid being pumped. Diesel fuel and used oil may contain debris or contaminants which require the use of a fine mesh screen strainer. All hoses must have airtight connections to enable fast priming. PLUMBING CONNECTIONS Pump ports have external 1 Inch hose barb and 1/2 Inch NPT Female threads. Use hose that does not kink when bent and with sufficient wall thickness to prevent collapse when used on suction side of pump. Hoses should be routed so that some fluid will be retained in pump body to wet the rotor and vanes.
