DUAL-LINE/TWO-LINE Automatic Lubrication System For Steel Plants

In steelmaking and rolling production, equipment operates under long-term high temperature, heavy load, and continuous operation.Lubrication failure can directly lead to downtime, production accidents, or even equipment scrapping. Therefore, the DUAL-LINE/TWO-LINE automatic centralized lubrication system has become an important means to ensure the stable operation of equipment in steel plants.

In the past, a common centralized lubrication configuration in steel plants was the ZPU08/14 lubrication pump combined with DSG / DSL dual-line metering devices.

This system is mature in structure and suitable for covering large-scale equipment lubrication requirements.With continuous technological advancement, CISOLUBE has now introduced ZP lubrication pumps with DSG / DSL dual-line metering devices,bringing customers in the steel industry a more efficient and reliable centralized lubrication solution.

ZP Lubrication Pump — The High-Pressure, High-Flow Core of Lubrication

The ZP series lubrication pumps are specially designed for large-scale equipment such as steel plants, cement plants, metallurgy, mining, and port machinery.They provide stable and reliable lubrication supply in harsh industrial environments.They are suitable for high-viscosity grease and can deliver grease uniformly over long pipeline distances.
