SERVICE
Your Aurora pump requires no maintenance other than periodic inspection, occasional cleaning and lubrication of bearings (MODEL 344A only). The intent of inspection is to prevent breakdown, thus obtaining optimum service life. The liquid end of the pump is lubricated by the fluid being pumped and there- fore does not require periodic lubrication. The motor, however may require lubrication, in which case, the motor manufactur- er’s recommendation should be followed.
LUBRICATION OF IMPELLER SHAFT BEARINGS
The MODEL 344A pump is available with three options for lubricating the shaft bearings. They are:
1.Regreasable (standard)
2.Oil Lubrication
3.Sealed Bearings, Permanent Lubrication
Regreasable bearings will require periodic lubrication and can be accomplished by using the zerk or lubrication fittings in the cartridge cap and power frame. Lubricate the bearings at regu- lar intervals using a grease of high quality. Polyurea base
