The DCR-50 oil pump uses an electromagnet as a power source to drive the piston up and down under the aid of a spring to achieve the purpose of oil absorption; easy to install, simple wiring;has warning function of insufficient liquid level and abnormal detection; whas motor self-protection device to prevent over-temperature and overload; when the oil pump is running, the pressure gauge can be displayed on the pressure gauge. The controller screen displays the lubrication time (seconds) and the intermittent time (minutes); the indicator light shows the operating status of the lubrication pump, with the"RST" button for forced lubrication; the pump has a wide range of applications. It can be used in centralized lubrication systems for machine tools, textiles, printing, plastics, light industry and automated machinery. The pump is equipped with a 1 liter,2 liter fuel tank,uses oil viscosity 32-68cst, and cleans the tank for up to 6 months depending on the working conditions.
