The G series metering pump, also known as the MACROY® pump, is now NSF/ANSI 61 and 372 certified for municipal compliance and safety assurance. Capable of handling pressures up to 175 psi (12 bar) and flow rates up to 310 gph (1181 l/h) it is an ideal pump for water treatment applications. Combining heavy-duty industrial drive technology with state-of-the art design and manufacturing processes, this mechanically-actuated diaphragm pump eliminates flow restrictions, reduces the possibility of hydraulic oil contamination of process liquid, and ensures smooth output.

CENTRAC pumps combine a unique constant stroke length drive mechanism and electronic variable speed drive technology. The unique drive system provides a steady state accuracy of +/- 0.5% over the entire turndown range. This is twice the accuracy of the standard +/- 1% of most metering pumps. Greater accuracy means better control of the treatment process and more efficient chemical usage. In addition, these pumps offer a 100:1 turndown ratio. The advanced design enables the pumps to respond instantly to changes in dosage rate, making it the ideal metering pump for a wide range of flow rates in water and wastewater treatment applications.

MAXROY series is a rugged, industrial grade of metering pumps designed for applications up to 290 gph (1,100 l/h) at pressures up to 406 psi (28 bar). Its cast iron housing with chemical resistant coating enables the pump to be used in the harshest environments.

The MILROYAL® series metering pumps are the most reliable, industrial-duty metering pumps for critical processes in industries such as oil and gas, chemical and petrochemical processing, and industrial water treatment. The key to its success is its modular design that accepts a variety of liquid ends and other options that perfectly tune it to your process requirements. With three different frame sizes, these pumps provide precision chemical dosing over a wide range of capacities and pressures.

mROY series metering pumps control chemical dosing with unmatched accuracy and reliability. This dosing pump is durable, compact in design and enables metering of some of the harshest chemicals with repetitive steady-state accuracy at a ±1% range. It’s not unusual to find mROY metering pumps still operating at design performance after 20 or more years of service. That’s because mROY maximum uptime pumps are comprised of a unique set of technical features that deliver consistent chemical injection performance with minimal maintenance requirements.

Primeroyal series pumps combine robust, field-proven technology, flexible design, and chemical delivery accuracy, making these metering pumps suitable for a large number of industrial processes. The pumps feature a variable eccentric drive that enables precise control of the pump delivery rate while meeting or exceeding industry standards for steady-state accuracy and repeatability. It has an efficient design that achieves reliable performance within a minimal footprint.
