Plunger Pumps

ITT (now Xylem) sold the Marlow Plunger Pump product line to Wastecorp in 1993. This includes all proprietary engineering drawings, specifications, tooling, patterns, molds and more. Today, this product line is manufactured and marketed under the Sludge Master® brand name. 
With a legacy of over 80 years, Wastecorp improves plunger pump technology by engineering innovative upgrades on our newest models and producing genuine replacement parts that are of the highest quality and performance for current and previous models under the former brand name. Wastecorp also manufactures replacement parts for Komline-Sanderson and Carter plunger pumps
