Product Overview

The EP-EALP-G Series Grease Electric Drive Piston Pumps are high-performance lubrication systems engineered for heavy-duty and industrial applications. Designed with an advanced electric piston pump mechanism, they deliver consistent grease flow even under demanding working conditions — ensuring optimal lubrication for critical moving parts across construction, mining, and agricultural equipment.
Compared with conventional manual or pneumatic grease systems, the EP-EALP-G Series offers a smarter, fully automated solution. Its compact motor-driven piston design provides precise metering and high-pressure output up to 350 bar, reducing downtime and maintenance frequency while extending component life. The pump’s electric drive allows programmable lubrication cycles, maintaining continuous lubrication throughout long operating shifts — ideal for excavators, wheel loaders, tractors, and OEM machinery systems.
Field data from end-users show that machines equipped with the EP-EALP-G Series achieve 35 – 45 % higher lubrication efficiency and extend maintenance intervals by over twice compared to conventional systems, delivering tangible cost savings and longer service life for vital components.
Key Features & Advantages
The EP-EALP-G Series combines robust engineering with intelligent lubrication control, offering a reliable and efficient solution for professional equipment maintenance. Below are its main features and advantages:
Automatic & Intelligent Lubrication
Built-in micro-control modules automatically activate grease supply according to pre-set time or working cycles. The pump supports PLC integration or standalone operation, allowing flexible configuration without manual adjustment.
Multi-Point Grease Distribution
Designed to handle 1 to 6 independent outlets, the system delivers precise grease quantities to multiple points simultaneously. Each outlet provides consistent flow, ensuring even distribution and preventing over- or under-lubrication.
High-Pressure Piston Performance
The core piston pumps structure generates stable pressure up to 350 bar, enabling long-distance and multi-line grease delivery without clogging or flow loss — a major advantage for large agricultural and construction equipment.
Low Maintenance & Energy Efficiency
Thanks to low starting current and optimized motor design, the EP-EALP-G pump reduces power consumption while extending service intervals. Overload protection and low-level alarms improve system reliability. Tests show up to 40 % lower maintenance frequency and 25 % less grease waste.
Rugged & Environment-Resistant Construction
Built with corrosion-resistant aluminum housing and IP65-rated sealing, the pump performs reliably in harsh environments with dust, humidity, and temperature extremes — from farm fields to mining sites.
Applications & Replacement Cases
The EP-EALP-G Series is a direct replacement for BEKA EP / EP-1 lubrication pumps, fully compatible with original interfaces and mounting dimensions — installation typically takes less than 30 minutes. The product has been successfully applied across multiple industries and equipment brands worldwide.

Construction Equipment
Widely used in CAT Bagger M318, VOLVO, KOMATSU, and other excavators. Field testing shows that replacing BEKA pumps with EP-EALP-G units improves lubrication stability by around 30 % and extends bearing life by over 40 %.
Agricultural Machinery & OEM Systems
Perfect for harvesters, tractors, balers, and other machinery working in dusty or high-temperature environments. The electric-piston design prevents lubrication failure and unplanned downtime. OEM clients benefit from customized control interfaces and voltage options (12 V / 24 V DC) to fit different system designs.
Industrial & Mining Equipment
In conveyors, crushers, and heavy hydraulic systems, the EP-EALP-G pump operates continuously for over 20 000 hours under high-pressure conditions, outperforming traditional pneumatic pumps with superior consistency and durability.
Selection & Installation Guide
Model Selection Tips
Choosing the right configuration of the EP-EALP-G Series Grease Electric Drive Piston Pump ensures optimal performance and service life. The selection process mainly depends on the lubrication system’s layout and grease consumption.
-
Number of Outlets:
Select the pump version based on the total lubrication points of the machine.
– Small and medium equipment: 1–3 outlets
– Heavy-duty or multi-joint machines: up to 6 outlets -
Pump Element Type:
Choose between PE-125 or PE-175 pump elements depending on required grease output.
– PE-125 : standard output for medium systems
– PE-175 : high-volume type for long pipelines or multi-point lubrication -
Power Supply Voltage:
Available in 12 V DC and 24 V DC options to fit different electrical systems used in construction, mining, and agricultural machinery.
Proper selection guarantees that the piston pump lubrication system operates at the correct pressure and flow rate, maximizing efficiency and extending equipment life.

Installation Instructions
To ensure reliable and safe operation, follow these standard installation practices:
Mounting Position:
Install the pump vertically, with the oil outlet facing upward to allow smooth grease flow and air release.
Power Connection:
Verify the input voltage (12 V or 24 V DC) and connect the motor following the wiring diagram provided in the manual.
Grease Line Preparation:
Before startup, make sure all lubrication lines are clean, unobstructed, and free of air pockets.
Initial Start-Up:
After filling the reservoir, run the pump briefly to confirm proper discharge and pressure build-up at each outlet.
Following these guidelines helps maintain consistent pressure and uniform grease delivery across all lubrication points.
Maintenance & Care
Regular maintenance keeps your electric lubrication system performing at its best and prevents costly downtime.
-
Oil Level & Alarm Check:
Inspect the grease level and the low-level alarm indicator regularly — ideally before every work shift. -
Filter Cleaning:
Clean or replace the grease filter every six months to prevent contamination or clogging in the distribution network. -
Motor & Electrical Inspection:
Ensure all wiring terminals remain tight and corrosion-free. -
Operating Practices:
Avoid running the pump without grease for long periods, as dry operation may damage internal seals and piston components.
Routine servicing not only extends pump lifespan but also improves the overall reliability of the lubrication circuit.
Troubleshooting Guide
| Issue | Possible Cause | Recommended Action |
|---|---|---|
| No grease discharge | Faulty piston element or loose motor wiring | Check and tighten wiring, inspect or replace the pump element |
| Warning light flashing | Low grease level or sensor malfunction | Refill grease reservoir or inspect the level sensor |
| Unstable pressure | Blocked distributor or faulty relief valve | Clean distribution lines or adjust/replace the relief valve |
By addressing these issues promptly, users can restore normal operation quickly and minimize downtime. In most cases, the system resumes stable function after simple inspection or part replacement.
FAQ
How often should the EP-EALP-G piston pump be serviced?
Regular maintenance is recommended every 6 months or after approximately 2,000 operating hours, depending on usage conditions. During each service, check the grease level, clean the filter, and verify that all wiring and outlets are free from blockage. Routine inspection helps maintain stable pressure and prolongs pump life.
Can the pump run on both 12 V and 24 V systems?
Yes. The EP-EALP-G Series is available in 12 V DC and 24 V DC versions, designed to fit most agricultural and construction machinery electrical systems. It’s important to confirm the voltage before installation to prevent motor overload or startup failure.
Is the EP-EALP-G compatible with BEKA EP/EP-1 systems?
Absolutely. This model is a direct replacement for BEKA EP and EP-1 pumps, featuring matching dimensions and interfaces. It can typically be installed in under 30 minutes without modification, maintaining full system compatibility while offering upgraded performance.
What type of grease is recommended for this lubrication pump?
Use standard grease or oil with viscosity up to NLGI #2, suitable for progressive lubrication systems. For best results, ensure the grease is clean and moisture-free before filling, and store it in sealed containers to prevent contamination.
