The challenge

An injection moulding company had experienced consistent failures over two years from its eight x 18.5 kW chiller pumps feeding chiller units.


We made an initial site visit to collect data, and then brought that back to our headquarters.

The solution

We fed the data through our flow analysis software, which gave us the necessary pressures, friction loss, flow rate and load information we needed to design a solution. We also analysed the existing pump performance curves to get an understanding of all the current flow rates and pressures.


We specified, sourced and supplied eight new 15 kW centrifugal pumps, and installed them without turning the system off, which saved downtime.


The results over five years

Once we had finished the work, the failures had been completely eliminated. As the trusted supplier to the injection moulding company, we have been in regular contact with them to help maintain and service their equipment. They had achieved payback within six months.


Over the last five years, they have saved 500,000 kWh per year, which is £50,000 per year in power alone, and £250,000 over the five years.
In addition, they have had zero pump failures, which has saved them significant amounts of downtime.
