The Weatherford WDD 1100 is a heavy HDD mud pump rated at 7500 PSI max working pressure and 1033 GPM max flow, with 1600 HP rated input power, an 8 in stroke and a rated speed of 135 SPM. Its factory liner chart runs from 7.5 in down to 4 in: the 7.5 in liner delivers 1033 GPM at up to 2230 PSI, the 6 in liner 661 GPM at up to 3475 PSI, and the 4 in liner 294 GPM at the full 7500 PSI. The power end frame is welded from high-strength low-alloy steel and stress-relief heat treated after welding, giving a strong strength-to-weight ratio and avoiding the internal shrinkage or cracking risks of cast frames. The crankshaft and connecting rods are integrally forged from high-strength alloy steel, then quenched, tempered, precision machined and dynamically balanced for stable running. We supply replacement fluid-end parts for the WDD 1100 across Canada, the United States and international oil and gas markets.
