The Jabsco 18685-000 rotary vane pump is ideal for pumping light oil or transferring diesel fuel. This is a self priming pump 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 continuous duty in applications with a total system head no greater than twenty feet and when pumping liquids with a similar viscosity of diesel fuel. When pumping light oils, the duty cycle should be no longer than thirty minutes. The pump can be used as a portable pump or mounted permanently in a pumping system. The pump can be mounted on any flat surface and 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.
The pumps ports are an external 1 in. hose barb and 1/2 in. NPT female threads. Use a hose that does not kink when bent and that it has a sufficient wall thickness to prevent collapse when used on the suction side of the pump. Hoses should be routed so the fluid will be retained in the pump body to wet the rotor and vanes to aid in priming. Use a mesh 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.
All hoses must have air-tight connections to enable fast priming.
Note: Explosion hazard. Do not use where flammable vapors are present. Do not pump gasoline, solvents, thinners, or other flammable liquids. To do so can cause an explosion resulting in injury or death.
