3L Lubrication Pump – Automatic Oil Pump

What This Pump Does This 3L lubrication pump automatically feeds oil or grease to your machines. It holds 3 liters of lubricant and pumps it out at 90-300 ml per minute. No more manual oiling – just set it up and let it work 24/7. Perfect for CNC machines, milling equipment, grinders, and injection molding machines. The pump keeps your machines running smooth and cuts down on breakdowns. Many shops see their maintenance costs drop by 30-40% after installing these pumps. The 3.6 kg pump comes with different voltage options (24V DC, 110V AC, 220V AC, 230V AC) so it works with most shop power setups. You can control it manually, with a timer, or connect it to your PLC system.

A 3L oil lubrication pump is an automatic oil pump with a 3-liter reservoir designed to deliver oil to machine parts that need regular lubrication. It is commonly used in CNC machines and other industrial equipment. What are the benefits of a 3L oil lubrication pump? A 3L oil lubrication pump offers stable oil delivery, compact size, and easy integration into automatic lubrication systems. It helps reduce wear, improve machine reliability, and lower maintenance effort. What pressure can a 3L oil lubrication pump provide? According to the product information, this pump can operate at a maximum pressure of 25 bar, or 2.5 MPa. That makes it suitable for low to medium-pressure oil lubrication systems. What is the flow rate of a 3L oil lubrication pump? The pump provides a flow rate of about 90 to 300 ml per minute. This controlled output is useful for precise lubrication of bearings, guides, and other moving parts. What type of machines use a 3L oil lubrication pump? It is commonly used on CNC machines, milling machines, grinders, injection molding equipment, and other industrial systems that require regular oil lubrication. What voltage options are available? Depending on the model, the pump may support 24V DC, 110V AC, 220V AC, or 230V AC. The right voltage depends on the machine and control system. Can a 3L oil lubrication pump be controlled automatically? Yes, it can be controlled manually, by timer, or through a PLC system. This makes it suitable for both simple and fully automated lubrication setups. What oil viscosity is suitable for this pump? The pump is designed for oil with a viscosity range of about 22 to 1300 mm²/s. Using the correct viscosity helps maintain smooth flow and reliable performance. How should a 3L oil lubrication pump be maintained? Maintenance should include checking the oil level, inspecting tubing and fittings, and ensuring the pump is operating at the proper pressure. Regular cleaning and using the correct oil help extend service life. Can a 3L oil lubrication pump be used in automatic systems? Yes, it is designed for automatic lubrication applications and can be integrated with timers, controllers, or machine PLC systems. This makes it suitable for continuous industrial use.
