Jinpinlub Central Lubrication System Electric Grease Pump
J203 is an automatic centralized lubrication pump that can support up to 3 pump elements and provide up to 150 lubrication points, suitable for scenarios such as construction machinery, bus chassis, small and medium-sized machinery, and conventional industries.
Description
Features
1. J203 lubrication pump without follower plate
Function of reservoir and stirring paddle: The oil tank stores lubricant, the cover is pollution-proof and convenient for refueling, and the ventilation device ensures air circulation in the oil tank when the pump is running. The stirring paddle homogenizes the lubricant and assists the pump in sucking oil.
Pump base and internal connection: The base accommodates the motor, electrical connections, refilling accessories and up to 3 pump elements, and the output of different elements varies.
2. J203 lubrication pump with follower plate
Reservoir and special parts: The function of the reservoir is similar to that of the pump without follower plate, and the ventilation device plays a role during operation and filling. The newly added follower plate presses the oil with a spring, and the contact rod realizes low liquid level detection and indication through the reed contact.
Connection and function expansion: The function of the pump housing remains unchanged, and the electrical connection adds the liquid level indication function. The connection types are square plug or M12 plug.

Maintenance
1. The lubrication pump does not run
– Power failure: the upper machine is turned off, the connection cable is loose or damaged, the external fuse is blown, check and repair.
– Operation mode problem: in the pause time mode, adjust the operation mode.
– Internal failure: the motor, power board is damaged or the internal cable is broken, professional inspection and repair or replacement of parts.
2. The lubrication pump runs but the oil supply is small or no
– System component failure: the electric lubrication system is blocked, the one-way valve or pressure relief valve is damaged, replace the faulty parts.
– Lubrication pump component problem: the oil suction hole is blocked, the component is closed, the lubricant has bubbles or abnormal viscosity, check and handle the pump components and lubricant.
– Metering device problem: the metering device is configured incorrectly, reconfigure it correctly. Ensure that safety measures are in place and operate according to regulations before maintenance.
