What are the Advantages of EP-EALP-G Series Electric Lubrication Pumps?

01# Optimized Lubrication Intervals

The EP-EALP-G series electric lubrication pump provides substantial benefits over conventional manual lubrication systems by allowing precise control of lubrication intervals. Users can accurately set these intervals down to the minute, ensuring that machinery receives timely lubrication without any delays.

02# Enhanced Production Efficiency and Equipment Uptime

A key feature of the EP-EALP-G series is its ability to deliver lubricants without necessitating equipment shutdowns. This capability allows operations to continue uninterrupted during emergencies, ultimately enhancing overall equipment uptime and productivity.

03# Reduction of Lubricant Waste and Equipment Failures

This series employs a targeted lubrication strategy, dispensing small quantities of lubricant multiple times during operation. This approach not only reduces waste but also significantly improves lubrication effectiveness. By providing the correct amount of lubricant at specific times and locations, the EP-EALP-G series minimizes the risk of part failures, which are often associated with traditional manual lubrication methods.

04# Safer Working Environment

The EP-EALP-G series features integrated control systems that enable real-time adjustments to lubricant quantities from a safe distance. This functionality ensures high efficiency while allowing timely modifications to adapt to varying operational conditions. Furthermore, once installed, the system reduces the need for personnel to enter hazardous lubrication areas that may be hard to access due to exhaust emissions or confined spaces, thereby improving workplace safety.

05# Labor and Time Cost Savings

Designed to meet various operational needs, the EP-EALP-G series comes in multiple sizes, allowing for substantial grease reserves. This feature promotes long-term operation with less frequent grease replenishment, leading to significant savings in both labor and time costs associated with maintenance.

06# Prevention of Over-Lubrication and Under-Lubrication

The EP-EALP-G series effectively addresses common issues in lubrication management. Over-lubrication can cause excess heat buildup, wasted lubricant, and increased labor costs, while under-lubrication can result in excessive wear on components, higher energy consumption, and increased operational expenses. This pump maintains the right balance, ensuring optimal equipment performance.

07# Lower Maintenance and Spare Parts Costs

By reducing the risk of unplanned maintenance and the necessity for spare parts, the EP-EALP-G series electric lubrication pump maximizes equipment utilization. This proactive approach not only avoids unexpected downtime but also leads to more efficient resource management, ultimately resulting in cost savings for your operations.

In summary, the EP-EALP-G series electric lubrication pump is an innovative solution that enhances lubrication efficiency, safety, and overall productivity while significantly lowering costs related to maintenance and operational disruptions.

SIMPLE INTRODUCTION OF THE PUMP BODY WORK

The direct current motor(10)continuously rotates the eccentric convex wheel (5) and the pressure ring (6). This kind of eccentric wheel influence the suction and pressure stroke of the piston （7)， The check valve(8)  in the pump core prevents the delivery medium from being sucked out of the line.Churn-dasher(2) Through the filter (4) push the lubricating agent out of the oil storage drum（1) The filter screen reduces the air bubble in
the aluminum base(3). The volume of lubricating agent remaining in the oil storage drum（1) can be detected by direct inspection through the scraper mounted on the stirring (2). Safety valve(9) is preset to 300 bar.

INSTALLATION SIZE

EP-EALP-G has five different models of oil storage barrels to meet different lubrication requirements.

PUMP CORE AND SAFETY VALVE

The pump core and safety valve components are of separable design
The ines can be directly connected to the pump core under specific requirements

EP-EALP-G Grease Low Level Alarm

In addition to the standard configuration, a low liquid level alarm device can be added based on specific requirements. To facilitate the alarm function, a capacitive proximity switch is installed inside the oil barrel. When the oil level is adequate, the pump operates normally. However, when the oil level falls into the low range, the pump ceases operation, and the display indicates "ERO." At this point, the pump must be filled with oil (the minimum fill level should not be less than the top of the sensor), after which the forced start button can be pressed. This allows the pump to resume operation at the last recorded time.

The proximity switch can also be connected to an external control unit or PLC. Once connected, the pump will stop working when the low liquid level is detected, prompting timely oil replenishment. If the lubrication pump does not feature a low-level alarm device, it is important to ensure that sufficient grease is added beforehand to prevent false alarms when the power is turned on.
