Dual Line Grease Lubrication System

DUAL LINE GREASE LUBRICATION SYSTEM

Optimize your industrial machinery performance and eliminate unexpected mechanical failures with the premium Dual Line Grease Lubrication System by Lubsa Multilub. Specifically engineered for massive, complex machinery configurations—such as those found in steel plants, cement factories, mining operations, and heavy manufacturing units—this centralized setup delivers a powerful, highly dependable greasing solution across vast distances.

The Dual-Line Advantage

Unlike single-line progressive systems that can completely lock up if a single point gets blocked, a dual-line system operates using two independent main lines that alternate carrying pressurized grease. This intelligent design ensures that even if one lubrication point encounters high backpressure, the rest of the network continues to receive precise, metered grease quantities without interruption.

Key Technical Features & Components

Alternating Pressure Lines: Two parallel main lines run throughout your plant equipment, distributing heavy-duty grease (up to NLGI Grade 2) alternately via an automated change-over valve.
Precision Metering Devices: Custom-configured dose feeders sit at each friction point, injecting an exact, adjustable amount of grease directly into the moving bearings.
Integrated Control Panel: Equipped with automated line-fault indicators, emergency stops, and low-level alerts to keep plant operators fully informed of system integrity in real-time.
Pneumatic End-Pressure Relays: Built-in end sensors monitor line termination pressures, safely signaling the control unit to toggle line cycles and prevent over-pressurization.

Why Heavy Industries Rely on Dual-Line Architecture:

When your production lines extend over hundreds of meters with hundreds of critical points, manual greasing introduces catastrophic human error. A centralized dual line lubrication system guarantees continuous protection while the machine is running, cutting down component friction wear, slashing grease consumption by up to 50%, and preventing costly unscheduled downtime.

A dual line grease lubrication system delivers precise amounts of grease to multiple lubrication points simultaneously using two independent lines and metering devices. Here’s a detailed breakdown of how it works.

Components:

Reservoir: Holds the grease supply for the system.
Pump: Delivers pressurized grease to the two main lines. It can be operated electrically, pneumatically, or manually.
Two main lines: These run parallel throughout the equipment, each carrying grease alternately.
Change-over valve: This valve directs the pump’s pressure to one main line at a time while connecting the other to a relief line, creating the pumping action.
Metering devices: Located at each lubrication point, they measure and dispense the precise amount of grease required.
Delivery lines: Connect the metering devices to the individual lubrication points.

End pressure relay:-	It senses the end pressure and gives the signal to change the valve through the control panel. For checking the pressure two pressure gauges are provided.
Electric control panel:-	Panel has the features main on the indication, Manual and auto mode indication, Lines one and two on the indication, Line fault indication, Motor trip indication, Emergency stop button, and other standard controls. This control panel is available as per customer requirements.
Grease transfer pump:-	Grease transfer pump is a pneumatic version. This pump is directly mounted in the barrel. It transfers the grease to the reservoir of the pumping station.
