Data SheetOverview
The design of the DP-10 & DP-15 air operated double diaphragm pump provides high suction lift, even at dry startup and with heavier fluids (incorporating internal check valves). No close fitting or sliding parts are at risk – the pump can run dry without damage. Pumps will run at any setting within their operating range simply by adjusting the air inlet pressure and system conditions. One pump can fit a broad spectrum of applications. Pumps transport easily to the application site. No complex controls to install or operate, simply connect an air supply, attach fluid connections, and the pump is ready to perform.
