20Pages

Heavy-duty, high pressure diaphragm pumps. These industrial-built pumps are designed to handle all of your high pressure and volume diaphragm pump needs with minimal maintenance required. Their innovative, external manifold design allows for normal servicing to be done from one side of the pump, thereby eliminating the needfor dismounting. These pumps are excellent for chemicalspraying where higher pressures are desired, such as insecticide spraying, air blast and tall tree sprayers. They also work great for high pressure cleaning and dis- infecting applications, such as poultry house cleaners. Control Units 9910-GH50 & 9910-BMH50 > Control units are available for easy flow and pressurecontrol of your sprayer system. These units include a pressure relief valve to control pressure, an oil-filled pres- sure gauge to monitor pressure, and an outlet valve to control flow. Control unit 9910-BMH50 can be remote mounted with Kit No. 9910-KIT999. Refer to the adjoining chart to select the proper control unit for your pump. > Max flow: 28.5 gpm Max flow: 37.6 gpm Max flow: 39.7 gpm Max flow: 49.8 gpm Max pressure: 725 psi Max pressure: 725 psi Max pressure: 725 psi Max pressure: 725 psi Max speed: 550 rpm Max speed: 550 rpm Max speed: 550 rpm Max speed: 550 rpm 3Diaphragms 3Diaphragms 4Diaphragms 4Diaphragms ControlMax.Max.PumpUnit ModelGPMPSIModel 9910-GH5051725All models9910-BMH5041725All 110,140 and 160 Series >
