Plastic-Diaphragm-HeadsAquFlow continues to expand its product line in response to the customer requirements. Due to the popularity and specific customer demand we have developed plastic liquid ends for low flow Series 1000 pumps and the entire Series 900 pumps. Not only does that fill a gap in our range of corrosion resistant materials but it also adds a lower cost alternative to the more expensive metals required for the applications. These liquid ends are now available for 3/8″, 9/16″ and 3/4″ plunger sizes in Series 1000 as well as the entire range of 3/16″, 1/4″ and 3/8″ plunger sizes in Series 900 pumps.

These liquid end options are available in a variety of plastics including PVC and PVDF. In addition to the diaphragm head and the check valves made from these corrosion resistant materials our pump liquid end also includes PTFE diaphragm and contour plate in a similar corrosion resistant plastic. The diaphragm heads up to the 3/8″ plunger size includes a contour plate that is built in to reduce the number of parts and increase the ease of service and repair. While PVC is a popular option for use with Sodium Hypochorite, Ferric Chloride etc., PVDF is solid against any corrosion from most harsh chemicals such as acids etc.
