The Honghua HHF-1300 HHF-1600 W SWOP 7.5K 8404-25A FE configuration pairs the HHF-series power end with the SWOP 8404-25A fluid end, rated for a maximum working pressure of 7500 PSI and a maximum flow of 772 GPM at a rated speed of 120 SPM. The SWOP design physically separates the suction and discharge functional areas into distinct modules, restructuring the stress field inside the fluid end, and joining the modules into a single high-pressure unit requires highly precise connection techniques. A quick-change valve cover system is standard on the 8404-25A assembly, improving maintenance efficiency while preserving high-pressure sealing safety. Factory ratings by liner size are: 4 in at 297.4 GPM and 7500 PSI, 4.25 in at 331.4 GPM and 7449 PSI, 4.5 in at 367.2 GPM and 6723 PSI, 5 in at 444.3 GPM and 5556 PSI, 5.5 in at 528.8 GPM and 4669 PSI, 6 in at 573.7 GPM and 3978 PSI, and 7 in at 772 GPM and 2988 PSI. We supply matching fluid-end wear parts to drilling contractors across Canada, the United States and international markets.
