Product Overview
The EP‑EALP‑G Series Grease Electric Drive Piston Pumps are engineered for environments where reliability is non‑negotiable. With a robust electric piston design, these pumps deliver measured quantities of lubricant with remarkable consistency, even in rugged conditions encountered in construction, mining, and agricultural operation.
When compared to traditional manual or pneumatic grease systems, the EP‑EALP‑G significantly reduces labor dependency and ensures that every lubrication point receives the precise amount of grease at the right time. Thanks to its high‑pressure capability (up to 350 bar), this system efficiently supports extended lines and multiple lubrication points without fluctuation or loss of pressure, helping prolong machine life and uptime.
End‑user performance reports indicate a remarkable improvement in lubrication efficiency—35% to 45% higher—and more than double the interval between maintenance cycles when compared with conventional alternatives. These improvements translate into tangible savings in both time and operational costs.
Key Features & Advantages
The EP‑EALP‑G Series integrates advanced mechanical design with intelligent control logic to deliver a proven lubrication solution for professionals who demand performance and durability.
Automatic & Intelligent Lubrication
With integrated control units, the pump can be configured for time‑based or cycle‑based lubrication delivery. Standalone operation is supported, and the system can also be integrated into a centralized PLC logic for synchronized machine control, removing the need for manual intervention while ensuring precision.
Multi‑Point Grease Distribution
The system supports up to 6 independent outlets, delivering even and consistent grease distribution to each feed point. This eliminates the common problem of uneven lubrication, which can accelerate wear or cause premature failures in moving components.
High‑Pressure Piston Performance
Thanks to its optimized piston architecture, the EP‑EALP‑G delivers stable, high‑pressure output capable of driving lubricant through long pipelines and multiple feed points with minimal flow reduction. It’s ideal for demanding, large‑scale machinery where grease must reach distant or hard‑to‑access points.
Low Maintenance & Energy Efficiency
Designed with an energy‑conscious motor and low starting current requirement, this pump reduces electrical loads and extends service intervals. Built‑in overload safeguards and low grease level alarms add another layer of operational reliability, reducing unnecessary downtime.
Rugged & Environment‑Resistant Construction
The corrosion‑resistant aluminum body and IP65 rated sealing ensure dependable performance across extreme ambient conditions—from dusty fields to high‑humidity industrial environments. This durability makes the EP‑EALP‑G a trustworthy choice for long‑term, heavy‑duty use.
Applications & Replacement Cases
Designed as a direct fit replacement for BEKA EP / EP‑1 pumps, the EP‑EALP‑G Series maintains the same mounting and interface specs, making upgrades seamless and installation straightforward—often under 30 minutes.
Construction Equipment
Widely deployed on excavators from CAT, VOLVO, KOMATSU, and others, field tests have confirmed up to a 30% increase in lubrication stability and a 40% extension in bearing life when replacing older systems with the EP‑EALP‑G.
Agricultural Machinery & OEM Systems
A reliable choice for tractors, harvesters, balers, and other high‑use agricultural vehicles. Designed to withstand dusty conditions and temperature variations, the electric piston pump reduces the risk of lubrication failures and unscheduled machine stops.
Industrial & Mining Equipment
Proven to operate reliably for over 20,000 hours in demanding applications such as conveyor systems, crushers, and heavy hydraulic mechanisms, outperforming many traditional pneumatic solutions in durability and consistency.
Selection & Installation Guide
Model Selection Tips
Choosing the proper EP‑EALP‑G configuration ensures that your system runs at optimal pressure and grease flow based on machinery demands.
- Number of Outlets: Determine based on total lubrication points—1–3 for smaller machines, up to 6 for complex systems.
- Pump Element Type: PE‑125 for standard output; PE‑175 for higher volume requirements or extended pipelines.
- Power Supply Voltage: Available in 12 V DC and 24 V DC versions for compatibility with a wide range of machinery electrical systems.
Selecting the right model ensures efficient lubrication, reduces maintenance, and prolongs overall equipment life.
Installation Instructions
For safe, efficient setup, follow these practices:
- Mounting Position: Install vertically with outlet facing up to prevent air locks and ensure steady grease flow.
- Power Connection: Confirm voltage and adhere to wiring diagrams to avoid electrical issues.
- Grease Line Preparation: Clean all lines prior to startup to eliminate blockages or entrapped air.
- Initial Start‑Up: Perform a brief test run to verify flow and pressure across all outlets.
Maintenance & Care
Consistent maintenance preserves pump performance and avoids unexpected service interruptions.
- Oil Level & Alarm Check: Inspect grease levels and alarm indicators regularly.
- Filter Cleaning: Clean or replace filters every six months to prevent contamination.
- Motor & Electrical Inspection: Check that all wiring and terminals are clean and secure.
- Operating Practices: Refrain from prolonged dry running, which may damage seals and internal components.
Troubleshooting Guide
The table below lists common issues, their likely causes, and suggested remedies:
| Issue | Possible Cause | Recommended Action |
|---|---|---|
| No grease discharge | Loose wiring or worn piston element | Tighten wiring; inspect or replace piston element |
| Warning light flashing | Low grease level or sensor problem | Refill grease or check sensor |
| Unstable pressure | Distribution blockage or relief valve issue | Clear lines or service relief valve |
FAQ
How often should the EP‑EALP‑G piston pump be serviced?
