Designed from the ground up for high pressure–low flow applications, AquFlow’s Series 900 is the lowest flow hydraulic diaphragm metering pump on the market, with flows down to 0.01 GPH (less than 40 mL/hr). Made in compliance with API 675, the Series 900 can pump flow capacities up to 6.5 GPH at pressures as high as 3,000 PSI.

Aquflow delivers customized chemical injection solutions for your choice of model depending on your application, whether it’s in oil & gas, pharmaceutical, food, or other chemical dosing industries. With a turndown ratio of 10:1, the Series 900 dosing pump delivers a chemical metering pump accuracy of ±1% with options for manual and auto capacity controls.

Like all AquFlow diaphragm dosing pumps, the Series 900 comes equipped with a built-in internal safety relief valve to prevent over pressurization. Its gear drive is fully enclosed and bathed in oil, reducing friction and protecting the internals of the pump from harsh environments. The metering pump diaphragm provides accurate controlled amounts of chemicals and require significantly less maintenance than peristaltic pump tubes. This low-maintenance and long-lasting design makes the AquFlow’s Series 900 positive displacement metering pump one of the most reliable and efficient low flow metering pumps.
