AY series centrifugal oil pump is a brand-new one redesigned on the basis of Y type one and by means of absorbing the advanced foreign know-how and used for the demand of the modernization construction and for quick suitability to the updating equipment taking energy-saving as the center. It features:
Use 45, 56, 70 bearings to replace the former 35, 50, 60 ones, enhancing the reliability.
A high effective energy saving hydraulic model is used for the hydraulic portion, the average efficiency is higher than that of Y type by 5 8%.
Toensure the inheritance, the type of structure, external and installation dimensions and performance range of this pump are made identical to those of Y type so as for the oil apparatus to be easily reformed.
Refined selection of materials, the main body takes the materials of, categories as the base, the bearing etc. Partsare made of cast steel and cast iron two materials, providing the use at a cold outdoor and on a ship with a benefit condition.
The parts are widely universal and the standard parts can be used mutually for several series products.
Three cooling ways are available with the bearing: Air, blower and water cooling, selectable upon different medium temperatures. Of which the blower cooling is especially suitable for the area lack of water or of a poor water quality.
