⚙️ API 676 Gear Pumps (Viking / Roper / Maag, Volumetric Slip <5.0%, 150 bar Pressure)

API 676 External Gear Pump Volumetric Slip Calculator

Size heavy-duty external spur and helical gear pumps (API 676 / Viking / Maag / Roper): calculate laminar slip leakage flows ($Q_{slip} propto rac{Delta P cdot h^3}{mu}$) through tooth tip and side face clearances ($h < 0.05 ext{ mm}$), evaluate speed derating across high viscosities ($1 ext{ to }500,000 ext{ cP}$), and oil/gas pumping profits.
