Chem-Feed C-1500N diaphragm metering injector pumps have a permanently lubricated gear motor for smooth, quiet performance. The valve body and fittings are constructed of chemical resistant PVDF. Valves have FKM static seals and TFE/P ball seat O-rings. The diaphragm is made of PTFE-coated EP. The design allows for a minimum stroke length of 5%. Time is adjustable from 5% to 100% of the repeating 5-second time interval, which results in precise, high-frequency injections. The pump is NSF, ETL, CSA and CE listed.
AWWA CEO David LaFrance thanks water professionals nationwide for keeping water safe for drinking
Dec. 16, 2014, marked the 40th anniversary of the Safe Drinking Water Act (SDWA), which today includes regulations for more than 90 contaminants. American Water Works Assn. (AWWA) CEO David LaFrance issued the following statement to mark the occasion.
The Chem-Pro M Series metering pump has a large, easy-to-read LCD that shows output rate, a 4-20 mA output, a stainless steel pump head and NSF 61 listing. The pump also features the single-piece DiaFlex diaphragm, manufactured 100% in house of molded Kynar, which offers zero delamination or breakdown. Optional advanced communications include Industrial Ethernet, Modbus TCP, ProfiNet, Modbus and Profibus.
Flexflo peristaltic metering pumps are suited for smaller-scale applications with maximum outputs of 124 gpd and working pressures reaching 100 psi. The A-100N Series is compatible with a range of chemicals, featuring three tube material options: Norprene, Tygothane and FKM. It cannot vapor lock or loose prime, and has a tube failure detection system. It is designed to be compatible with the Micro-Flo flow verification sensor, with select digital models accepting 4-20 mA, 0-10 Vdc inputs for eternal speed control.
