Why does small sumps cost more than larger sumps?

Process fluids may seem like a relatively small expense, but then you might forget the cost for coolant waste, which is often hidden in a central account.

Small sumps have more frequent fluid changes than larger ones, because they are more difficult to manage and therefore often suffer from bacterial outbreaks. Sending small volumes to disposal means higher costs in the long run, since you normally have to pay for transport. The volume of a small sump is often inaccurately calculated and is rounded up.

One person order – another department gets the invoice

A problem is when the person who order the fluid change is not the one who gets the invoice. For a stressed machine operator or maintenance, it´s easier to replace the fluid than to find the reason why it´s bad. This cost does not affects the department's budget, since it´s often on a central account.

Those who take the largest expense for small sumps does not know about it.

Difficult to achieve environmental goals

More and more companies aim to reduce waste, despite the increasing challenges of keeping a long service life of the process fluid. Stricter legislation is resulting in less available biocides, which is leading to more exposure to microbial growth and increased sensibility of variations in concentration.

Work pro-active

The most important measure to reduce the amount of fluid waste is to have a strategy for keeping the bacteria under control. There must be someone who is responsible for each sump, no matter how small it is, and who can take measures to increase the life of the fluid.
