Sewage Treatment Plants

Trouble-free plant operation during the entire cleaning process is imperative for treatment of waste water. Important machine elements such as chains, spindles, roller and sliding bearings are directly exposed to dirt, water, phosphates and other chemicals. Continuous relubrication is necessary to prevent premature wear.

Advantages of Automatic Lubrication

perma lubrication systems seal and protect lubrication points against contamination.
Less maintenance runs minimize the time that workers spend in dangerous areas and increase workplace safety.
Different sizes and precise settings, based on manufacturer recommendations, prevent lubricant starvation and save lubricant.
Environmentally friendly, bio-degradable lubricants in closed systems.

Solutions

Direct mounting on the lubrication point:
e.g. perma FLEX

Easy, quick mounting
For lube-points with little vibration / shocks
For easy-to-access and safe lubrication points

Remote mounting to the lubrication point:
e.g. perma STAR VARIO

For lube-points with strong vibration / shocks (isolation of lubrication system)
When workers’ safety is at risk: Mounting in safe areas
For hard-to-access lubrication points
