The Honghua HHF-1300 HHF-1600 W MERRIMAC 7.5K 7595-21A FE configuration pairs the HHF-series power end with the MERRIMAC 7.5K 7595-21A fluid end, at a rated speed of 120 SPM. Instead of a traditional one-piece casting, the pump frames use a welded structure of high-strength low-alloy steel plates chosen on rigorous mechanical grounds. Both models employ integral forged herringbone gear sets for primary reduction; the double-helix tooth layout makes the axial forces generated by the left and right gear halves cancel each other, so the pinion-shaft and crankshaft main bearings carry only radial loads, which extends bearing life. Pressure and flow ratings for this configuration are available on request. We supply matching fluid-end wear parts to drilling contractors across Canada, the United States and international markets.
FAQ
What are the pressure and flow ratings of the HHF-1300 HHF-1600 W MERRIMAC 7.5K 7595-21A FE configuration?
The rated speed for this configuration is 120 SPM. Detailed pressure and flow figures are ratings available on request — share your liner size and duty conditions and we will confirm the applicable values.
What does the MERRIMAC 7.5K 7595-21A FE designation refer to?
It identifies the specific fluid-end assembly fitted to Honghua HHF-1300 and HHF-1600 pumps in this configuration. When ordering parts, quote the full model string so we can match the correct fluid-end components.
How are the HHF-1300 and HHF-1600 frames and gears built?
The frames use a welded high-strength low-alloy steel-plate structure rather than a monolithic casting, and both models use integral forged herringbone gear sets whose self-canceling axial forces leave the main bearings carrying radial loads only, extending bearing life.
