What grade is the hydraulic oil for metering pumps?
Thread Content
Gentlemen! What grade of hydraulic oil do you use for the metering pumps in your factory?
Our unit uses 46# hydraulic oil for the Riwa hydraulic diaphragm pump
We use ordinary machine pump lubricant, grade 46.
The manual states that 30-grade machine oil actually refers to the current HL-46# (which is the standard type); L-HM-46 anti-wear hydraulic oil is also used
As a supplementary note, the hydraulic oil used in that chassis is 25# transformer oil; the main function of transformer oil is insulation. Do not use hydraulic oil in that interior compartment
The viscosity of hydraulic oil varies depending on the pump model and operating conditions; it should be used in accordance with the manufacturer’s specifications
This place is a bit confusing; what does \"intermediate\" refer to? Is it on the hydraulic side or inside the transmission box? Or somewhere else
