Blackmer announces that its STX Sliding Vane Pumps are an effective process and transfer solution for chemical industry applications. STX Series transport pumps are ideal for loading and unloading corrosive and non-corrosive liquids - sulfonic acids, specialty chemicals, solvents, latex paints, liquid sugars and vegetable oils - that are not compatible for use with cast iron pumps.

To manage these fluids STX pumps are made from 316 stainless steel with external ball bearing construction, non-metallic Duravanes, PTFE elastomers and Blackmer chemical mechanical seals to provide longer transport pump life with corrosive products. The STX offers high capacity flow rates up to 250 gpm (946 lpm), differential pressures up to 125 psi (8.6 Bar) and pump speeds up to 800 rpm, delivering fast fluid off-loading. A 6,000 gallon (22,700 liter) tanker can be unloaded in about 24 minutes.

The pump’s non-metallic vanes self-adjust for wear and to maintain flowrate, while minimizing shear and agitation. An adjustable relief valve protects the pump from excessive pressures. It has excellent self-priming and dry run capabilities and maintenance is reduced because internal wear is almost completely limited to the easily replaced sliding vanes.
