Vanton have released a new thermoplastic vortex pump head designed to handle solid-laden acids and caustic materials.
The company's SGV Vortex Pump Head for vertical thermoplastic pumps is able to handle fluids and slurries containing stringy materials or solids to 51 mm in diameter.
Built with solid thermoplastic construction of all its wetted components allows for the corrosion-free, abrasion-resistant handling of acids, caustics and a wide range of solids-laden wastes at temperatures to 135°C.
The SGV pump head features a recessed, dynamically balanced clog-free impeller that allows solids to pass through the pump without blockage, and is offered on Vanton SG Series sump pumps for depths to 6.1 m, and SGK cantilevered bearingless run-dry pumps for depths to 1.2 m.
All fluid-contact components of the pump are available in abrasion-resistant polypropylene (PP), polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC) or polyvinylidene fluoride (PVDF), which are chemically inert to the corrosive fluids they are specified to handle, unlike metallic components.
The heavy-duty stainless steel shaft is fully isolated from the fluid by a thick-sectioned thermoplastic sleeve, eliminating metal contact with the pumped fluid.
The company also offers horizontal centrifugal thermoplastics pumps with Vortex and other hydraulic heads, as well as sealless peristaltic pumps and integrated non-metallic tank/pump systems for handling of corrosive treatment chemicals and collected wastes spanning the entire pH range with no corrosion of the pump, and of ultrapure liquids and reagent grade chemicals with no contamination or ionisation of the fluid.
