PumpLinx: Computational Fluid Dynamics (CFD) Design Tool for Predicting Flow and Cavitation in Pumps, including: Axial / Centrifugal / Crescent / Gear / Gerotor / Lobe / Piston / Ring / Side Channel / and Vane Pumps. SimericsMP: General Purpose Multi-Physics CFD for modeling Heat, Flow and Cavitation, including Blowers, Fans, Mixers, Propellers, and Valves.
DUAL GEAR PUMP

Dual Gear Pump Design:

A dual gear pump has 2 side-by-side gear pumps that share the same inlet and outlet. In many cases those two pumps have a 180 degree phase shift.

Advantages:

A dual gear pump provides increased flowrate while reducing flow ripple and minimizing balance loads.

Application:

Transmissions, hydraulics, fluid transfer.

Dual Gear Pump Pressure
Dual Gear Pump Cavitation

PumpLinx: Solve Flows, Pressures, Cavitation, and Loads:
