Product Overview
The EP-EALP-G series electric grease pump is built for heavy-duty machinery that demands consistent, centralized lubrication. Whether in freezing cold, wet conditions, or dusty job sites, this pump delivers grease smoothly and precisely to keep critical components protected. Powered by a high-torque DC gear motor and precision piston pumps, it ensures stable output stroke after stroke, minimizing wear and extending equipment life during long operating hours.
Compact and rugged, the pump features a pressure-resistant alloy housing with a modular core that adapts easily to grease reservoirs from 2L to 8L. It supports 1 to 6 outlets, making it simple to scale from single-point to multi-point systems. Users often report cutting grease usage by more than 25% and stretching maintenance intervals from weekly to monthly after switching from manual or pneumatic systems.
Why EP-EALP-G Stands Out: Real-World Reliability
Compared to traditional greasing methods, the EP-EALP-G delivers measurable improvements in performance and cost:
- Accurate delivery: 0.125 cm³ or 0.175 cm³ per stroke per outlet – just the right amount, no waste, no dry spots.
- High-pressure stability: Rated at 350 bar with a 300 bar safety valve, it maintains flow even under heavy loads.
- Energy efficient: Low-power DC motor (~50W) starts smoothly and runs reliably on battery or vehicle power.
- Built to last outdoors: IP6K9K rated, proven in 1,000-hour salt spray tests with zero leaks.
- Quick to configure: Add or adjust outlets in about 10 minutes without disassembling the pump.
These features translate to smoother operation, longer service intervals, and maintenance costs typically reduced by around 30%.
Application of Product
The EP-EALP-G has been field-proven in demanding applications:
- Road construction equipment: Replaces BEKA EP/EP-1 systems in pavers, milling machines, and rollers for high-pressure chain, bearing, and slider lubrication.
- Agricultural machinery: Keeps harvesters, tractors, and seeders running with reliable lubrication at joints, drivelines, and pivot points.
- Industrial lines: Supports 24/7 operation in food processing, steel mills, and paper production with centralized systems.
- OEM integration: 12V/24V compatible, weighs just 4.2 kg (2L model), with standard mounting points for easy factory installation.
Whether equipping new machines or upgrading older fleets, the EP-EALP-G integrates seamlessly and boosts uptime. Need spec sheets, installation guides, or demo videos? Just reach out – we’ve got you covered.
Installation Guide: Get the EP-EALP-G Grease Pump Running Right
A few extra minutes during setup can save hours of headaches later. Follow these steps for a smooth start.
- Pre-install check: Mount the reservoir vertically on a level base. Blow out all lines with compressed air to keep debris away from the precision piston pumps.
- Wiring: Match your 12V or 24V system—reverse polarity will fry the motor. Use waterproof aviation plugs and verify voltage stays within ±10% with a multimeter.
- Tubing: Run Ø6 mm high-pressure nylon or steel-braided lines with a minimum bend radius of 50 mm. Apply a thin coat of sealant to fittings and torque to 25 N·m to prevent leaks.
- Commissioning: Power up and idle for 1 minute; watch the gauge climb to 50–100 bar. Check each outlet for steady grease drops, then tweak the divider valves until every lube point feeds evenly.
- Safety notes: Never run dry longer than 30 seconds—it chews up the pump core. Every 500 hours, test the relief valve with a grease gun to confirm it pops at 300 bar.
Maintenance & Care: Simple Habits, Years of Service
Routine care is straightforward and pays off big in longevity.
- Grease choice: Stick with NLGI #1 (cold weather) or #2 (standard) lithium-based grease, max 3% solids to avoid clogging outlets.
- Cleaning: Wipe the reservoir lid and motor vents monthly. When swapping reservoirs, drain old grease first to prevent clumping.
- Check-ups: Every 200 hours, log motor current (normal 2–3 A), system pressure (150–250 bar while running), and clear any blocked outlets with a stiff wire.
- Quick troubleshooting:
- No output: Test voltage, then pull the cover and inspect O-rings for cracks.
- Pressure spikes: Relief valve spring may be tired—swap it in 5 minutes.
- Motor running hot: Grease too thick or ambient over 60°C; switch to lower viscosity or add a cooling fan.

FAQ
How often should the EP-EALP-G grease pump be serviced?
Under normal operating conditions, it’s best to inspect the system every 200–300 hours. Check motor current, system pressure, and outlet flow to ensure everything runs smoothly. With clean grease and proper setup, a full maintenance check is usually only needed every 1,000 hours or more.
Can the pump handle high-viscosity grease or work in cold environments?
Yes. The EP-EALP-G is equipped with precision piston pump cores that can handle grease up to NLGI #2. For temperatures below -20°C, switch to NLGI #1 lithium grease to keep flow smooth and protect the seals from stress caused by thickened grease.
Is the system compatible with BEKA EP/EP-1 or similar lubrication setups?
Absolutely. The mounting dimensions and electrical specs are fully compatible with BEKA EP/EP-1 systems. You can replace your old unit directly—no need to modify power wiring or piping. Most installations take less than 30 minutes.
What’s the best way to prevent clogging or uneven grease delivery?
Make sure all lines are clean before installation, and always use filtered grease. Periodically purge old grease or trapped air from the system. If one outlet stops feeding, remove and clean the divider valve instead of forcing pressure through—it protects the piston pumps and extends seal life.
Customer Reviews
⭐⭐⭐⭐⭐ Liam Carter, Service Engineer, AlphaRoad Equipment, UK
We installed the EP-EALP-G grease pump on two of our pavers last season, and it’s been flawless. Easy setup, strong pressure, and zero leaks so far. It cuts down manual greasing time by a lot—our team jokes that the pump works harder than we do.
⭐⭐⭐⭐⭐ Elena Petrova, Technical Supervisor, Baltic Construction Group, Estonia
Solid performance in every condition. We’ve run it through dust, rain, and freezing mornings—no issues at all. The piston pump delivers grease evenly, and the bearings look brand-new even after months of use.
⭐⭐⭐⭐⭐ Hiroshi Tanaka, Equipment Maintenance Lead, Tokyo InfraTech, Japan
Compact, powerful, and very quiet. The EP-EALP-G runs smoothly on our 24V systems and keeps the paver chains perfectly lubricated. Definitely a smart upgrade from our old BEKA setup.
⭐⭐⭐⭐⭐ Lucas Martins, Fleet Manager, AgroTrac Solutions, Brazil
Just plug it in, mount it, and forget about it. The electric grease pump takes care of everything automatically. We’ve gone from weekly greasing to monthly checks, and the operators are thrilled—less mess, less hassle, more uptime.
⭐⭐⭐⭐⭐ Sofia Nguyen, Operations Coordinator, MegaRoad Machinery, Australia
This little unit is tougher than it looks. After 800 hours on-site, it’s still pumping strong with consistent pressure. The grease usage is down, maintenance team is happy, and so am I. Great product!
