Performance for item STX2A-DEF

At 500 RPM and 50 psi differential pressure, the STX2A/STX2A-DEF pump requires 225 lb-in (25.4 N·m) of shaft torque with a fluid viscosity of 1,000 SSU.

At 500 RPM and 50 psi differential pressure, the STX2A/STX2A-DEF pump delivers 39 gpm (148 lpm) of a fluid in the 100 to 2,500 SSU range.

Item Overview for Blackmer STX2A-DEF
The Blackmer STX2A-DEF brings stainless steel high-speed sliding vane pump construction to LPG, propane, and anhydrous ammonia service. A corrosion-resistant relief valve protects the system from damaging pressure spikes. The bare-shaft build lets integrators match an existing drive or specify a new one. As part of the SGL lineup, it shares parts and service procedures with the rest of the range. Throughput climbs to 60 GPM, giving operations headroom during peak transfer windows. The drivetrain pairs a double-ended drive shaft with laminate vanes, keeping volumetric efficiency stable between rebuilds. Mechanical seals work alongside FKM elastomers to contain aggressive media and resist chemical attack. Installation stays simple thanks to weld flanges that match common piping practice. Consistent output supports accurate loading, batching, and inventory reconciliation.
