The GY series lubrication pumps, together with distributors, piping, and other accessories, form a centralized lubrication system that enables automated, centralized lubrication of multiple lubrication points. This system is particularly well suited for applications with a large number of lubrication points, high lubrication frequency, unattended operating environments, areas that cannot be manually lubricated, and harsh operating conditions.

　　 Product Features:

　　● Periodic automatic lubrication with adjustable operating time and interval; precise oiling volume.

　　● Can drive up to three pump elements (oil outlets), and, via a grease distributor, can supply lubrication to as many as hundreds of lubrication points;

　　● Can operate normally at low temperatures as low as -40°C, and can convey oils of NLCI grade 2 or lower, or mineral oils with a kinematic viscosity of 40 mm²/s (cSt) or greater, within the temperature range of -25°C to 70°C.

　　● Enables operation and monitoring of independent zones, as well as oil-level low and pipeline blockage alarms.

　　● Set the safety pressure to ensure the safety of equipment and personnel;

　　●2,000 hours of trouble-free operation.

　　 GY-Y(A)H-Lubrication Pump

　　After being pressurized by three pump cores, the grease passes through a safety valve and is then distributed via three distributors to individual lubrication points (bearings and small gear bearings). The pump’s start-up and shutdown are controlled by a time controller according to a pre-set program. When the pressure in the pipeline exceeds the set pressure of the safety valve, the safety valve automatically relieves pressure.

　　This pump unit is widely used in centralized lubrication systems for pitch, yaw, and main shaft applications in the wind power industry.
