AWWA’s New Standard: Progressive Cavity Chemical Metering Pumps

The American Water Works Association (AWWA) has released the first edition of the ANSI/AWWA E200-18 standard for progressive cavity (PC) chemical metering pumps. This standard demonstrates the quality and reliability of PC pumps for chemical metering applications. 

All AWWA standards are developed in a rigorous, defined manner with due process to interested parties and stakeholders to ensure all views and objections are considered. The result is a true industry consensus that can be trusted and widely accepted.

SEEPEX BRAVO Chemical Metering Systems are equipped with NSF/ANSI 61-certified SEEPEX PC chemical metering pumps. PC pumps are self-priming and dose accurately with low-shear, laminar flow and no vapor lock. Pulsation dampeners can be eliminated due to minimal pulsation. Chemical consumption is reduced, and slip is minimized even if fluid temperature, viscosity or discharge pressure fluctuates. PC pumps also wear predictably without risk of catastrophic failure.

BRAVO is used in a variety of industries for disinfection, pH control, flocculation, corrosion inhibitors, oxygen scavengers and containment elimination. The plug-and-play packaged skids minimize time and cost associated with engineering, procuring, assembling and installing flow control systems. 

BRAVO is fully integrated, modular and scalable. Systems can be adapted to any layout and are available in simplex, duplex or triplex pump configurations for floor or wall mounting. BRAVO incorporates user-customized, color-display touch-screen controls. Systems handle pressure ratings up to 175 psi with flow rates from 0.1 gph up to 250 gph.

SEEPEX Inc. is an ISO 9001-2015 certified manufacturer and a leading international supplier of PC pumps, systems, accessories and services. SEEPEX takes a consultative approach to offering innovative products and customized solutions for fluids handling and processing applications in nearly every industry.
