AY series single two level centrifugal pumps which are reformed and redesigned on the base of original Y type lube pump series. In order to meet the construction of the modernization adapt to the requirement of replacing the old with the new one soon which is focused on the sizing the energy, so we develop this new product, it has the following characteristics:

1. The original bearing body parts35, 50, 60 are replaced by bearing body45, 55, 70, in this way its reliability can be increased.

2. The hydraulic excess flow part adopt the hydraulic model of the high efficiency energy-saving Pump, in average, the efficiency is 5-8% higher than the old Y type lube pump.

3. In order to keep inheriting, the structure pattern, install size.

4. The lube pump pats have the strong all-purpose ability, its general-standard parts can be commonly used by several series.

5. The affiance of its selecting materials way and the principals part is mainly made of Ⅱ,Ⅲ kind material, the materials of some parts such as bearing body is up to two kinds, that is casting steel and casting iron, in this way, it makes very advantages for being used in the cold area, being used outdoor, using for ship making.

6. According to the different temperature, selecting hearing has three types that is air cooling, air fan cooling, water cooling, among them, air fan cooling is especially used for the area where the water resource is lack or the quality of water is worse.
