MHO series Vacuum Pump Oil
Short Description:
MHO series vacuum pump oil is suitable for spool valve pumps and rotary vane pumps that require rough vacuum.It is an ideal
lubricating material and is widely used in my country’s military industrial enterprises,display industry,lighting industry,solar energy
industry,coating industry,refrigeration industry,etc.
Product Introduction
● Good thermal stability,which can effectively reduce the formation of sludge and other sediments caused by temperature changes.
● Good high oxidation stability,greatly extending the service life of oil products.
Excellent anti-wear lubrication performance,greatly reducing interface wear during pump compression.
● Good anti-emulsification properties greatly extend the life of the equipment when operating at low temperatures.
● Good foam characteristics reduce vacuum pump wear caused by overflow and flow interruption.
Purpose
Avoid prolonged or repeated skin contact.If ingestion requires medical attention,protect the environment and dispose of product,
waste oil and containers in accordance with legal regulations.
