Termomeccanica Pompe D2, D2D, and DD2D pumps are between bearings, axially split, double volute, one and two-stage pumps.
The D2 model has two single suction impellers and a back-to-back arrangement.
The D2D model has two double suction impellers and volute is staggered to reduce pressure pulsations.
The DD2D model has a first stage double suction impeller and a second stage single suction impeller.
All models have a near centerline mounted casing. Hydraulics are optimized through extensive CFD analyses and experimental tests.
