AY type oil pump series is modified and re-designed on the basis of the old Y type oil pump series.

It is to meet the needs of modernization, as soon as possible to adapt to the energy-saving as the center of the equipment replacement and the development of new products, with the following characteristics: 1, bearing body parts will be the original 35,50,60 bearing body with 45,55,70 bearing body, improve the reliability.

2. The hydraulic flow part adopts the hydraulic model of high efficiency and energy saving pump, which is 5-8% higher in efficiency than the old Y-type oil pump on average.

3. In order to maintain the inheritance, the structure type, installation size and performance parameter range of AY type oil pump should be the same as that of Y type oil pump, which is easy to update and transform the old device.

4. High degree of universality of parts and components, common standard parts are shared by several series of products.

5. Material selection and refining, the main body is mainly made of Ⅱ and ferrous materials. The bearing body and other parts are increased into cast steel and cast iron, which provides favorable conditions for the use of ships in cold areas and in the open air.

6, bearing air cooling, fan cooling, water cooling three, according to the different use of the pump temperature selection.

Among them fan cooling is especially suitable for water shortage or poor water quality areas.
