Description
STX Sliding Vane Pumps
Blackmer® STX Series pumps, which are part of the Stainless Line of sliding vane pumps, offer fast fluid off-loading for high-temperature, high-viscosity applications. For example, typical off-loading of a 6,000 gallon (22,700 liter) tanker can be unloaded as quickly as 24 minutes. These pumps are made from 316 stainless steel with external ball bearings, non-metallic Duravanes, PTFE elastomers, and Blackmer chemical mechanical seals. STX pumps feature an adjustable relief valve, versatile mounting bracket, weld flanges and are self-priming.
