100% Dimensional Interchangeability
Our PWA Gen2 replacement maintains exact dimensional parity across every pump size group:
- Group 1 (1×1.5×6 through 1.5×3×8): 1-3/8″ shaft, 40 BHP max — compact frame, identical C-face motor adapter pattern
- Group 2 (3×4×7 through 4×6×13): 1-3/4″ shaft, 122 BHP max — most popular group, 12 pump sizes
- Group 3 (same sizes as Group 2): 2-1/8″ shaft, 200 BHP max — heavy-duty bearings, paired angular contact back-to-back
- Group 4 (6×8×13 through 8×10×16H): 250 BHP — large frame, identical foot pattern and shaft centerline
- Group 4-17 (4×6×17 through 8×10×17): 400 BHP — 17-inch impeller sizes, fully compatible
- Seal chamber options: Standard bore, Big Bore (improved cooling), and Taper Bore (self-venting) — all three options available
- Flinger disk lubrication standard — 30% increased bearing L-10 life vs. flood oil, ~15°F cooler operation
