M4 Hydraulic Gear Oil Pump 

M4 Gear Oil Pump is a common hydraulic pump, its working principle is to use the rotation of the gear to produce pressure, so as to achieve the delivery of liquid. M4 hydraulic gear pumps is a Hydraulic Power Unit. The M4 hydraulic gear pump is usually composed of two gears, one for the drive gear and the other for the driven gear. Drive gear is driven by a motor or other power source to make it rotate. The driven gear is subjected to the rotation of the driving gear, resulting in relative motion, which inhales the liquid into the pump chamber and pushes it out. The main features of M4 Hydraulic Gear Pumps include: 1. Simple structure, small size, light weight, easy to install and maintain. 2. Stable work, low noise, low vibration. 3. High working pressure and flow range. 4. Suitable for all kinds of liquids, including oil, water and other non-corrosive liquids. 5. High efficiency and reliability.
