Charles Ross & Son Co. unveiled improvements to the dual-post hydraulic lift and seal design of its 1,500-gallon multi-shaft mixer, Model PVM-1500. The new lifting design is a double-acting, fully hydraulic cylinder operating at a much higher pressure, allowing for a smaller cylinder and significantly less oil for operation, the company says. The net result is a lifting system that operates at lower cost, requires less maintenance for the end user, and provides faster lifting speed when raising and lowering the agitators. In addition, the new seal arrangement allows seal replacement without removing agitator shafts. Unlike the historical design, seal replacement no longer requires removal of the mixer from the tank nor tank entry to access the seal. The PVM-1500 features three independently driven agitators: a screw auger, a high speed disperser and a three-wing anchor agitator. The sides and bottom of the changeable mixing vessel are insulated and jacketed for as much as 50 psig. The vacuum-rated machine is designed to run 24/7, supplied with rugged touchscreen controls showing digital readouts for speed, cycle time, vacuum level and batch temperature.
