AquFlow
About
AcuFlow (formerly AquFlow, originally HydroFlo) has manufactured hydraulically actuated diaphragm metering pumps and chemical dosing systems in Irvine, California since 1972. Founded by John P. Klembeth, a former design engineer at BIF and Milton Roy, the company rebranded from AquFlow to AcuFlow in 2024 to reduce marketplace confusion. All pumps comply with API 675 standards with plus or minus one percent metering accuracy. The product line spans five series: the S900 for low-flow injection from 0.01 to 6.5 GPH at 3,000 PSI, the S1000 up to 123 GPH simplex at 3,000 PSI with unibody construction, the S2000 up to 180 GPH at 1,800 PSI with enclosed diaphragm design, the S3000 up to 920 GPH with corrosion-resistant construction and balanced diaphragm, and the S4000 up to 3,500 GPH duplex with less than one percent flow variation. Liquid end materials include 316SS, Alloy 20, Hastelloy C, PVC, PVDF, and PTFE. The Cheminjector system program offers five tiers from basic skid assemblies through fully automated systems with SCADA-compatible 4-20mA input, flowmeter feedback loops, and remote internet control. Accessory products include back pressure valves, safety relief valves, calibration columns, pulsation dampeners, and the IVAX verification and control system. Water and wastewater applications include dosing sodium hypochlorite, lime slurries, ferric chloride, alum, caustic soda, and polymers.
