Working Principle
The EP-EALP-G operates through a precision-engineered eccentric-driven piston mechanism. As the motor runs, the eccentric cam drives the piston in a back-and-forth motion, forcing grease through check valves and into the distribution lines. Each pump cycle delivers a fixed volume of grease at constant pressure, ensuring that each lubrication point receives exactly the same amount of grease.
The system includes a built-in check valve to prevent backflow and air ingress, ensuring consistent operation and stability. With an IP65-rated motor, the pump can withstand exposure to dust, moisture, and vibrations. The control system supports integration with external PLCs or can operate independently through standalone controllers, making it suitable for multi-point lubrication. Additionally, low-level alarms are triggered when grease levels fall below 20%, and pressure sensors can detect any anomalies in the outlet lines in real time.
The modular design of the EP-EALP-G allows for easy replacement or upgrades of the pump core, reservoir, motor, and control module individually. Available with 2L, 4L, or 6L reservoirs, and configurations supporting 1 to 6 outlets, the pump can be tailored to meet the specific requirements of your equipment.
With its robust construction and high-precision design, the EP-EALP-G Series has earned a reputation as a reliable, long-lasting lubrication partner for OEMs and end-users worldwide.

Installation & Maintenance Guide
Proper installation and regular maintenance are key to ensuring your EP-EALP-G piston lubrication pump operates reliably for years. For installation, the pump reservoir should be mounted vertically on a stable surface, away from vibration and heat sources. Make sure all connections are airtight to avoid air ingress, and the motor and control housing are designed to meet IP65 protection standards, ensuring durability even in harsh, outdoor, or dusty environments.
Before starting the pump, always perform a pre-start inspection. Check that the voltage is correct, the polarity is right, and the indicator light is on. Ensure the grease level is above the minimum mark, and run the pump unloaded for 1-2 minutes to expel any air trapped in the system. If the grease level drops below 20%, refilling is necessary. Use NLGI #2 grade grease, and do so slowly to avoid creating air pockets.
Routine maintenance includes checking and cleaning the suction filter every three months, verifying the safety valve pressure, and replacing piston seals or cartridges every 1,000 operating hours or semi-annually. If the equipment is idle for extended periods, seal the outlets and clean the reservoir to prevent grease from oxidizing or hardening. Regular inspection of system components, such as the pressure setting and grease lines, ensures smooth operation and prevents clogging or blockages that could impact system performance.
