Hypro/Pentair is no longer distributing the 9910 series of diaphragm pumps, components, and related parts; however, the pumps and repair parts are still available and will now feature factory labeling. 

These 2 diaphragm, medium pressure, epoxy-coated pumps achieve up to 14.8 gpm (56 lpm) and 580 psi (40 bar). Pressure and output are designed for optimum performance of small to medium-sized sprayers. Pentair Hypro medium pressure diaphragm pumps can be adapted for male 1-3/8" splined shaft, female 1-3/8" splined shaft, 1" solid shaft, or gear reduction drive options. Honda's GX series engines are legendary for superior reliability and performance. And there's no doubt about it: the GX160 lives up to the legend. Lower noise levels, lower vibration, and lower emissions without sacrificing power output or performance.
