Like ordinary centrifugal pumps, what grade of lubricating oil is generally used? If anyone knows any more, please share it; thank you. Bonus points
46# High-speed Pump 4413
What devices are number 32 generally used in?
46# oil for fully loss systems (formerly known as 46# machine oil); 32# is used in winter, while 46# is used in summer
In Ningbo, 68# is used; at the factory that produces outdoor pumps here in the northeast, 32# is used. Then, during summer, when it was felt that the viscosity wasn’t sufficient, it was changed to 46#
Ordinary centrifugal pumps use 46# turbine oil and 46# anti-wear hydraulic oil, while high-speed pumps use Great Wall YP4413
