Rolling mill - Grease

- Slow rotation,
- High temperatures and corrosive process water ingress.

Dropsa has brought innovation to Grease system design, reliability and monitoring to traditional Casting applications. In this application example – a traditional grease system – high reliability and ease of maintenance was achieved by using both modular pump package and modular divider valves. A flow monitoring system allows the user to know exactly how much grease is being injected in each segment of the machine

System Overview:

Total Number of Points:               from 50 to 600
Lubricant:                                   COLD: KPLK-20 ; HOT: KHC25
Total Grease Volume per cycle:   0,25 ÷3cm³/point
Operating Frequency:                 from 2h to 4h
Length of system:                       min 25mt, max 150mt

This case application was implemented using :

SUMO Grease Pump
Modular Direction (4/2) Valve
Modular Dual Divider Components

Benefits achieved

High reliability pump package solution with built in redundancy for 24 hour operation.
Easy swap out of pump modules on maintenance schedules
Quick, reliable and clean change-out of divider valves during maintenance
Flexibility in design and increased performance over traditional and competitor products
A flow monitoring panel that gives electronic monitoring of the volume of grease injection during each lubrication cycle
Flow monitoring provides grease consumptions for each segment.
Quick diagnostic of any potential problems.
