Feature:1. The product has professional lubrication and cooling, suitable for grinding machines, milling machines, drilling machines, lathes and other small processing machinery2. According to the working principle of electromagnetic induction, the power loss is low3. This pump is a plunger pump that is uniquely designed for accuracy forming grinders, with piston movement4. The discharge volume is 400‑500cc/min and the spit pressure is 1kgf/cm² with stable performance5. High quality stainless steel material can make sure the durability and stability of the productHow 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. When a new oil pump is installed for the first time, sometimes the oil pump makes a noise and does not supply oil due to the air in the pump core. At this time, the oil should be injected manually from the inlet of the oil pump w
