Oil & Gas. 

Milroyal pumps are ideal for high-pressure offshore applications. They consistently inject methanol, corrosion inhibitors, oxygen binders, and other corrosive substances in the harshest conditions in the most remote locations.

Chemical and Petrochemical Processing.

The harsh, toxic chemicals required for chemical processes require metering pumps that ensure accuracy in delivery of these critical and difficult fluids.  Milroyal pumps’ modularity allows a selection of liquid ends and configurations to ensure you get the right pump for chemicals being handled.

Industrial Water Treatment.

Industrial process water must be treated efficiently and cost-effectively in compliance with quality standards. The reliability of Milroyal pumps deliver accurate chemical delivery and provide long-term cost benefits
