D100 Automatic Grease Lubricator Single Point Automatic Lubrication Unit for Heavy Industrial Equipment

Introduction

The D100 Automatic Grease Lubricator is designed for heavy industrial environments where bearings and moving parts operate under high load, high temperature, heavy dust and poor maintenance conditions.

In industries such as metallurgy, cement, power generation and mining, traditional manual lubrication can no longer meet modern requirements for equipment reliability and service life.
The D100 provides stable, efficient and long-cycle automatic grease lubrication through timed, metered and point-specific control.

What Is the D100 Automatic Lubricator

The D100 is a self-contained automatic grease lubrication unit that operates independently and can be installed directly at or near lubrication points.

It automatically supplies grease to single or multiple lubrication points according to a preset cycle, without being affected by operator experience, working schedules or environmental conditions.

Unlike manual lubrication, the D100 effectively avoids:

Missed lubrication
Over-lubrication
Uneven grease distribution

The design goal of the D100 is not to replace a single manual greasing task, but to continuously maintain equipment in an optimal lubrication condition.

Working Principle: How Stable Lubrication Is Achieved

The D100 Automatic Lubricator initiates lubrication automatically through its internal drive and control mechanism.

Once activated, grease is pressurized internally and delivered to bearings or friction surfaces through lubrication lines at a constant pressure of 25–30 bar.

This high and stable output pressure ensures that grease effectively reaches lubrication points and forms a continuous and stable lubrication film, significantly reducing:

Direct metal-to-metal contact
Local dry friction
Abnormal bearing temperature rise

The entire lubrication process is performed without equipment shutdown and without manual operation, achieving true on-demand automatic lubrication.

Core Technologies & Performance Features

Large Grease Capacity

The D100 is equipped with a 1000 cc grease reservoir, approximately 2–6 times larger than comparable products.
Under normal operating conditions, it can run continuously for 6 months to 2 years, greatly reducing maintenance frequency.

Low Power Supply Design

Powered by four 1.5V alkaline batteries, the unit features low power consumption and can operate continuously for 7–8 months without external power supply.

High Output Pressure

With a working pressure of 25–30 bar, the D100 delivers stronger and more durable lubrication compared with conventional automatic lubricators.

Timed, Metered and Point-Specific Control

Lubrication is controllable, repeatable and standardized, eliminating randomness associated with manual lubrication.

Multi-Point Lubrication & Installation Flexibility

The D100 supports multi-point lubrication through distributors or dual-port valves.
A single unit can lubricate 1–4 lubrication points simultaneously.

Under constant pressure conditions, grease supply remains uniform at each lubrication point, regardless of distance or installation position, effectively reducing lubrication cost per point.

The compact structure allows on-site installation near equipment, supporting vertical or horizontal mounting and making it ideal for retrofit and equipment upgrades.

Applications: Industries & Typical Equipment

The D100 Automatic Grease Lubricator is widely used in:

Applicable industries

Metallurgy and steel plants
Cement plants
Power generation
Mining and chemical industries

Typical equipment

Motor bearings
Fans and pumps
Conveyors and elevators
Cranes and hoists
Crushers and roller presses

In elevated, dusty, high-temperature or hard-to-maintain locations, the D100 significantly improves lubrication conditions and operational reliability.

Overall Value & Service Commitment

Through continuous and stable automatic lubrication, the D100 delivers measurable long-term value:

Grease consumption reduced to 1/30–1/60 of manual lubrication
Practical grease savings of 50%–60% in real applications
Maintenance intervals extended by 2–3 times
Significant reduction in maintenance cost and safety risks
