Charles Ross & Son Co. recently announced that it has designed a new skid system capable of mixing and pumping low to moderately viscous products. The model VSL-400 design is a custom conical vessel on a movable skid with a progressive cavity pump rated for 10-30 gal/min.

A 5-HP inverter-duty motor drives a flange-mounted turbine mixer equipped with two axial flow impellers. The 34-in. diameter upper blade and 18-in. diameter lower blade reportedly maintain batch uniformity from start to finish of the pumping sequence. Both mixer and pump are controlled from a NEMA 4 weather-proof control panel, which includes a thermal protection system that disengages the pump motor if a set temperature is exceeded.
