Feature:1. Professional lubrication and cooling, widely used in grinding machines, milling machines, drilling machines, lathes and other small processing machinery2. According to the working principle of electromagnetic induction, the power loss is low, and it can be used continuously3. This pump is a plunger pump that is uniquely designed for accuracy forming grinders, with piston movement4. The pump core is equipped with a one‑way valve. This design is mainly to block the pump core when sand and dust in the lubricating oil enters, so as to prevent sand and dust from entering the guide rail5. Made of high quality stainless steel material, durable and long service life, with complete accessories, simple to installHow to Use:1. When replacing the oil pump, please clean up the wastes such as residues in the grease and iron key scraps. This will protect the oil pump and keep it from breaking for a long time. If wastes such as residues and iron filings are not cleaned up before replacement, the oil pump will suck in the residues and iron filings, which will cause the operation to stop, or even burn the oil pump in severe cases.2.
