Dual Line Lubrication System for Flotation Machines

In mineral processing, flotation machines are at the heart of the separation process—but they also represent one of the most demanding lubrication environments in the entire mine. Dust, chemical exposure, high moisture, and complex structures with dispersed bearings pose serious challenges to manual and outdated lubrication methods.

The Challenge: Harsh Conditions, High Failure Risk

Traditional lubrication methods cannot guarantee precise, even grease delivery under such harsh conditions. Over- or under-lubrication leads to premature wear, bearing failure, and costly unplanned downtime.

Our Solution: Dual-Line Lubrication System with ZP08/14/24 Dual-Line Lubrication Pump &  Dual-Line Distributors

The lubrication system company CISOLUBE provides a high-performance Dual-Line Lubrication System engineered to handle the extreme demands of flotation equipment. At the core of this solution are:

ZP08/14/24 Dual-Line Lubrication Pump

Heavy-duty electric pump designed for large-scale mining systems.

Operating pressure: Up to 40 MPa (400 bar / 5800 psi)

Flow rate options: 8000 / 14000 / 24000 ml/h

Reservoir capacity: 40L / 60L / 100L

Temperature range: -40°C to +80°C

Lubricant compatibility: NLGI 0# – 2#

With its high-pressure output and optional long-distance feeding, the ZP08/14/24 Dual-Line Lubrication Pump ensures every lubrication point receives metered grease—automatically and reliably.
