Performance characteristics and uses： The nominal pressure is 4.0Mpa vertically installed, and there is an overflow valve inside: to prevent the lubrication pump set from overloading. With unloading function: after the lubrication pump stops working, the oil pressure of the main circuit is removed, which is mainly used in the pressurized pressurized quantitative thin oil centralized lubrication system.Transparent resin tank or metal tank can be installed according to requirements, or retractable oil port can be added according to the need to be specified at the time of ordering. Supporting distributor: pressurized distributor, pressure relief distributor. Lubricating oil viscosity: 32-1300cst, 000#-00# lithium ester.
