Dual-line Lubrication Systems
CISO autmotic dual-line systems can be used on large systems with dispersed lubrication points that require varying lubrication quantities. These central dual line lubrication systems utilize two main lines that are supplied alternately with lubricant from a high-pressure pump via a change-over valve at up to 400 bar (5 800 psi) Branch lines, along the main lines, are connected with dual-line metering devices to supply a large volume of lubricant to the lubrication points Within large dual-line systems, end-of-line pressure switches are used to control and monitor the centralized dual line lubrication systems.
Products of Dual-line Lubrication Systems
MTP Manually Operated Pump
Suitable for Dual-Line and Progressive Lubrication Systems
ZP08/14/24 Lubrication Pump
Primarily utilized in dual-line systems or as supply pumps, the ZP08/14/24 pumps operate at a maximum pressure of 400 bar (5 800 psi).
DSG Dual-line Grease Metering Devices
Designed for dual-line systems with pressures up to 400 bar (5 800 psi), the robust DSG metering devices, made from galvanized steel, are available with up to eight outlets. Each pair of outlets features an indicator pin for visual inspection.
DSKH Metering Devices
The durable, galvanized steel DSKH metering devices are designed for dual-line systems with pressures of up to 400 bar (5 800 psi).
DSL Dual-line Metering Devices
The DSL metering devices, crafted from durable galvanized steel, are designed for dual-line systems and can withstand pressures up to 400 bar (5 800 psi). These devices, available with up to eight outlets, feature an indicator pin on each pair of outlets for visual monitoring.
WP-C Electric Change-Over Valve
The WP-C Electric change-over valve, an integrated detention control device, utilizes a high-torque DC deceleration motor to drive the movement of the valve sliding core. This movement opens and closes the oil supply pipeline or alters the direction of the oil supply.
DU-C Hydraulic Change-Over Valves
Primarily designed for dual-line lubrication systems, DU-C hydraulic change-over valves alternately discharge lubricant from the pump into one of the two main lines. The other line is linked to the pump’s return line connection. The switching pressure of these valves is adjustable.
MC-ⅠSystem Control Box
The MC-Ⅰcontrol equipment is specifically designed for managing and controlling a centralized lubrication system. The dedicated card installed within the equipment controls the system’s entire inlet and outlet signals.
EPW End-of-line Pressure Switches
EPW end-of-line pressure switches, crucial components in a dual-line lubrication system, are designed to oversee the system. They identify the pressure at the end of the respective main line and initiate the change-over procedure.
Attention of Automatic Dual Line Lubrication System Products
- Suitable for large systems with dispersed lubrication points
- Handles varying lubrication quantities per point
- High-pressure operation up to 400 bar (5,800 psi)
- Two main lines supplied alternately for continuous lubrication

Installation of Automatic Dual Line Lubrication System Products
CISO dual-line lubrication systems should be installed on easily accessible positions of the machine. Connect the two main supply lines to the change-over valve, which alternately pressurizes each line. Mount dual-line metering devices in branch lines as close to lubrication points as possible. Install end-of-line pressure switches at the farthest point on each main line to monitor system pressure and trigger automatic line changeover. All pipelines must be rated to withstand the maximum pump pressure of up to 400 bar.

Dual Line Lubrication Systems FAQs
Progressive lubrication systems vs single line lubrication systems vs dual line lubrication systems vs chain lubrication systems
| Feature | Progressive Lubrication Systems | Single-Line Lubrication Systems | Dual-line Lubrication Systems | Agricultural Machinery Lubrication System |
|---|---|---|---|---|
| Definition | Progressive lubrication system is an efficient lubrication system used for mechanical equipment, providing lubricant progressively to different parts of the equipment to ensure each part receives an adequate amount of lubrication. | The lubrication pump automatically delivers lubricant to the lubricant dispenser via a single supply line. Each dispenser serves only one lubrication point and can be adjusted to provide the exact dose of grease or oil required. | Dual-line systems can be used on large systems with dispersed lubrication points that require varying lubrication quantities. These systems utilize two main lines that are supplied alternately with lubricant from a high-pressure pump. | An automatic lubrication system for agricultural machinery is an intelligent system that provides quantitative and timed lubrication to key components of agricultural machinery. Through a lubrication pump and distribution device, it precisely delivers grease or lubricating oil to each friction point, ensuring stable operation of the equipment even under high loads, dusty, and humid environments. This system can significantly reduce manual maintenance, lower failure rates, and extend equipment life, thereby improving the overall operating efficiency and reliability of agricultural machinery. |

| Working Principle | The lubricant is pumped through the main lines to the progressive distributor with the pump. The lubricant is delivered "progressively" to the friction point. The circulation of a progressive distributor is monitored optically or electrically. | The dosing values are impinged on the main line with the pump – dynamically operating metering valves with a pressure surge, static operating dosing elements with slow pressure build-up. These thus transfer the respective quantity of the lubricant to the friction point. During the following relief phase, the lubricant is restacked in the dosing valves for the next lubrication process. | CISO dual-line systems can be used on large systems with dispersed lubrication points that require varying lubrication quantities. These systems utilize two main lines that are supplied alternately with lubricant from a high-pressure pump via a change-over valve at up to 400 bar (5,800 psi). Branch lines, along the main lines, are connected with dual-line metering devices to supply a large volume of lubricant to the lubrication points. Within large dual-line systems, end-of-line pressure switches are used to control and monitor the system. | Automatic lubrication systems for agricultural machinery deliver oil or grease automatically, periodically, and in precise amounts while the equipment is running. Lubrication pumps driven electrically or mechanically deliver lubricants through distributors or pipes to each lubrication point, keeping bearings, chains, gears, and other critical components well-lubricated, reducing wear and extending service life. |
