A high-performance mixing and pumping skid system

| By Mary Page Bailey and Gerald Ondrey

Ross & Son

This company recently designed a new skid system (photo) capable of mixing and pumping low to moderately viscous products. The Model VSL-400 system features a conical vessel on a movable skid with a progressive-cavity pump rated for flowrates ranging from 10 to 30 gal/min. A 5-hp inverter-duty motor drives a flange-mounted turbine mixer equipped with two axial flow impellers. The 34-in. dia. upper blade and 18-in. dia. lower blade maintain batch uniformity from start to finish of the pumping sequence. Both mixer and pump are controlled from a weatherproof control panel, which includes a thermal-protection system that disengages the pump motor if a set temperature is exceeded. — Charles Ross & Son Co., Hauppauge, N.Y.
