Product Overview
The EP-EALP-G series electric piston lubrication pump is a high-efficiency grease pump designed specifically for medium to large-scale equipment. It uses precision piston drive technology to deliver consistent grease output, maintaining accurate lubrication even in harsh conditions. Fully compatible with popular models like the Caterpillar 329D, it serves as a drop-in replacement for the German BEKA EP/EP-1 systems—matching perfectly in mounting interfaces, performance specs, and control logic.
Unlike traditional mechanical pumps, the EP-EALP-G uses an electric drive for intelligent operation, automatically adjusting lubrication cycles based on equipment workload. With a maximum output pressure of 350 bar and grease delivery up to 8–10 meters, it’s ideal for multi-point lubrication in agricultural machinery, construction equipment, mining vehicles, and large-scale manufacturing lines.
In Europe and North America, automatic electric piston pumps are fast becoming the go-to choice for OEMs looking to boost reliability and cut maintenance costs. Real-world data shows that equipment fitted with automated lubrication extends service intervals by over 30%, reduces failure rates by more than 25%, and saves up to 15% on grease consumption.
Product Features & Benefits
Built with a high-strength alloy pump core and precision-machined piston assembly, the EP-EALP-G stays rock-solid under continuous high pressure. Its dedicated drive motor ensures every lubrication cycle is spot-on, while the electronic timer allows adjustable intervals from 5 to 180 minutes—eliminating human error.
- Precise and Uniform Delivery: Piston-driven flow stays constant, avoiding the pulsation common in gear pumps.
- Extended Component Life: Timed, metered grease application cuts wear on bearings and joints, increasing part life by over 25%.
- Energy and Eco-Friendly: Optimized delivery improves grease efficiency by 10–15%, reducing waste.
- Smart Monitoring: Optional level sensors and pressure alarms provide real-time system status for uninterrupted operation.
- Low Maintenance: Modular design means pump cores or seals can be swapped in under 10 minutes with basic tools.
These strengths make the EP-EALP-G perfect for both standalone retrofits and OEM integration, delivering complete piston pumps lubrication solutions.
Working Principle
The EP-EALP-G operates on an eccentric-driven piston mechanism. When the motor runs, the eccentric cam drives the piston in a reciprocating motion, forcing grease through check valves into the distribution lines. Each cycle delivers a fixed volume at constant pressure, ensuring every lube point gets the exact same amount.
A built-in check valve system prevents backflow and air ingress, enhancing overall stability. The motor carries an IP65 rating, standing up to heat, dust, and vibration. The control system supports external PLC integration or standalone controllers for synchronized multi-point lubrication. Low-level alarms trigger when grease drops below 20%, and pressure sensors flag any outlet anomalies in real time.
Fully modular in design, the pump core, reservoir, motor, and control module can be replaced or upgraded individually. Standard models come with 2L, 4L, or 6L reservoirs and 1–6 outlets, easily tailored to different equipment sizes.
With its rugged build and high-precision drive, the EP-EALP-G series has earned trust worldwide as a reliable lubrication partner for OEMs and equipment operators alike.

Mounting Position & Orientation
Install the reservoir vertically on a stable surface, away from vibration and heat sources. Maintain airtight connections to prevent air ingress. The motor and control housing meet IP65 protection standards, suitable for outdoor or dusty environments.
Pre-Start Inspection
Before initial startup, verify voltage and polarity, confirm that the indicator light is on, and check that the grease level is above the minimum mark. It’s recommended to run the pump unloaded for 1–2 minutes to expel any trapped air from the system.
Grease Refilling & Low-Level Alarms
When the sensor signals low grease level (typically < 20 %), refill with NLGI #2 grade grease slowly to avoid trapped air bubbles. If system pressure exceeds 350 bar, check for blocked lines or distributor valves.
Routine Maintenance
Every three months, clean the suction filter and verify the safety-valve pressure setting. Replace piston seals or cartridges every 1,000 operating hours (or semi-annually). When equipment is idle for extended periods, seal outlets and clean the reservoir to prevent oxidation or grease hardening.
Following these maintenance steps will significantly extend the lifetime of your piston pump lubrication system, ensuring smooth, reliable operation and reduced service costs.
