Because of its compact size, durable construction, and reliable performance, the metering pump has applicability in a wide variety of applications

The most common applications include the injection of chemicals such as coagulants, biocides, disinfectants, polymers, softening agents, acids and bases for pH control, scale and corrosion inhibitors, oxygen scavengers, process additives, and many more.

Water and wastewater treatment. Water and wastewater must be treated efficiently, cost-effectively and within the appropriate quality standards.  Not only can pumps effectively and safely deliver a wide range of chemical additives, they are well-known for their reliability.  With preventative maintenance, these metering pumps can perform at peak levels for decades, leading to less shutdowns and long-term cost benefits.

Chemical and petrochemical processing. The durable design of the pump enables it to effectively withstand the toxic nature of processing fluids while its flow control capability can endure temperature and pressure variations during production.

Oil and gas production.  pumps are ideal for onshore oil and natural gas production because it can consistently inject methanol, corrosion inhibitors, oxygen binders, and other corrosive substances in the harshest conditions in the most remote locations.

Other industries include

• Food and beverages industry
• Pharmaceuticals production
• Power generation
• Agriculture
• Pulp and Paper
• Mining
• Many more
