The truck-mounted Ramjet from Vactor Manufacturing uses a Jet Rodder water pump to break up blockages and flush out debris in sanitary lines. Armed with up to 2,500 gallons of water in a stainless steel tank, it delivers flows of 60 to 100 gpm at 2,000 or 2,500 psi. The water pump is a single-piston, hydraulically driven, dual-acting pump that delivers a jackhammer action water flow, breaking through line blockages and scouring even the toughest caked-on debris from pipe walls. It can be configured with either a front- or rear-mounted hose reel. The auto wind hose guide allows hands-free operation from the control panel for a clean, tight wrap. 800/627-3171; www.vactor.com.
