CISO autmotic dual line lubrication systems can be used on large systems with dispersed lubrication points that require varying lubrication quantities. These centralized grease 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 Autmotic Dual Line Lubrication System

ZPU

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).

ZP01/02 Lubrication Pump

The ZP01/02 pumps, known for their high-pressure and high-volume capabilities, can function as supply pump units for small to midsize dual-line systems or progressive systems

Attention of Autmotic Dual Line Lubrication System Products

Do not install or remove the metering devices when the system is under pressure or the pump in operation.

Always protect the centralized dual line lubrication systems connected to the pump with a pressure reducing valve.

lncorrect operation may lead to damage resulting from insufficient or excessive lubrication of bearings or lubrication points.

Your own alterations or modifications of installed automatic dual line lubrication systems should only be carried out if approved with the manufacturer or his appointed dealer. Contact Cisolube centralized grease lubrication system for detailed information.

lnstallation of Autmotic Dual Line Lubrication System Products

For all work at the metering device, observe extreme cleanliness.

Attach the metering devices to even surfaces without tension. When base plates are used, first weld the base plates without the metering devices and then attach the metering devices onto them.

Protect the metering devices from dust and influences of heat (observe the maximum admissible operating temperatures).

The metering devices must be easily accessible for . check and installation work.

Before connecting the feed lines to the metering devices, fill them with lubricant.

when connecting the main lines take care to always connect the same line (l or ll) to the same metering device inlet.

This makes it easier to check of the metering device because all indicator pins are either in or out after each cycle.

Q

How does dual line lubrication system work?



A dual-line lubrication system operates using two main supply lines that alternately pressurize to deliver lubricants, such as grease or oil, to multiple lubrication points. When the first line is pressurized, lubricant is dispensed to half of the lubrication points, while the second line remains depressurized. Once the desired amount of lubricant is delivered, the system switches, pressurizing the second line and depressurizing the first. This alternating process ensures reliable and consistent lubrication even in large or complex systems. Dual-line systems are highly efficient, can handle long distances and numerous lubrication points, and are ideal for harsh industrial environments.
