HP 5L 650CC 4mm Manual Lubricating Oil Pump Left Hand Operated Lubrication Oiler for CNC Punching Lathe Cutting Milling Machine

【wide application】Widely used in lubrication system of CNC machine tools, machining center, production line, forging, textile, plastic, wood, rubber, mining, metallurgy, construction, printing, casting, auto, food and other mechanical equipment. 【working principle】When the handle is pressed by hand, the piston moves up and down under the action of a lever, which is a process of oil absorption; when the handle is loosened, the piston moves downward under the action of the spring force, and is an oil discharging process. 【lubrication system】The pump can be combined with a throttling distributor to form a centralized lubrication system. It is suggested that the oil viscosity is N20-N500. 【left hand operated】Right hand operated method, 4mm oil outlet diameter. 【0.6L】This is a small piston structure (tank volume: 0.6L) manual pump.
