🎛️ Overpressure Protection (Internal Re-circulating Relief vs External Full-Flow Tank Return)

Gear Pump Relief Valve & Overpressure Calculator

Model thermal runaway fluid overheating in internal bypass relief valves versus external full-flow return-to-tank lines for positive displacement gear pumps: size ASME relief valves preventing motor overload during dead-head discharge valve closure, calculate fluid recirculating temperature rise ($>150^circ ext{F}$ seizing risk), and piping safety margins.
