Charles Ross & Son Company made improvements to the dual-post hydraulic lift and seal design of its 1500-gallon Multi-Shaft Mixer Model PVM-1500.

Charles Ross & Son Company made improvements to the dual-post hydraulic lift and seal design of its 1500-gallon Multi-Shaft Mixer Model PVM-1500. The new lifting design is a double-acting, fully hydraulic cylinder operating at a higher pressure, allowing for a smaller cylinder and less oil for operation. 

The new seal arrangement permits seal replacement without removing agitator shafts. Unlike the previous 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 up to 50 psig. According to the company, this vacuum-rated machine can run continuously and is supplied with rugged touchscreen controls showing digital readouts for speed, cycle time, vacuum level, and batch temperature.
