3 Blackmer ® Pumps Used in DEF-Handling Applications STX3-DEF Series Sliding Vane Pumps The STX 3-inch pumps are designed for high-volume transfer to or from storage tanks, railcars, barges, or transports. They accommodate flow rates up to 250 gpm (946 L/min) with differential pressures up to 125 psi (8.6 bar) and maximum speeds of 800 rpm. STX1220A-DEF Series Sliding Vane Pumps This series is similar to the STX3-DEF series, but offers the lower flow rates some DEF handlers require – from 49 to 88 gpm (185 to 333 L/min). Some DEF handlers require the pumps meet all ISO 22241 material standards and cleanliness specifications required for DEF-handling applications.
