Hydraulically Actuated Diaphragm

The enhanced metering pump features improved component durability, it is easier to prime, it performs more efficiently and it is safer and simpler to maintain.

Accurate, repeatable flow control. The liquid end has been specifically designed for optimal chemical delivery.  Available in metallic or non-metallic materials, the liquid end features a high-quality double ball check valve for repeatability and accuracy, micrometer capacity control for precise dosage adjustment, and a bleed system for safer maintenance and easier commissioning.

Rugged enclosure. Dust-tight, cast-iron drive housing with a high-quality chemical resistant coating provides a rugged enclosure for operation in any plant and field environment

Application flexibility. Available in simplex and duplex configurations with a wide range of options and accessories, you can customize metering pumps for your most complex process needs.

Specifications and regulations. Our metering pumps meet all applicable regulations anywhere in the world where they operate. The Milton Roy pump also complies with API 675 specifications.

Performance by the numbers:
  • Flow rate from 0.20 gph (0.8 l/hr) up to 87 gph (330 l/h) in simplex configuration, or 174 gph (660 l/h) in duplex configuration.
  • Low and high pressure performance from 100 psi (5 bar) up to 3000 psi (207 bar)
  • Accuracy 1.0% over a 10:1 turndown ratio
  • Hydraulically-balanced diaphragm with 96,000 hours design life
  • Three-year warranty
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.
