Balcrank CenterFlo CF15 Pump – Patented Reverse Flow Design

The Balcrank 1120-023A CenterFlo CF15 pump introduces patented technology that redefines fluid handling in automotive and industrial applications. Unlike conventional diaphragm pumps, the CenterFlo design routes fluid through the center of the pump. Meanwhile, the air motor sits on the outside. This reversed design improves suction lift, reduces pulsation, and significantly lowers air consumption. With a maximum free flow of 15 GPM and operating range of 22–102 psi, the CF15 is built for transfer, dispensing, and evacuation tasks. It operates quietly and reliably, even in systems with back pressure. The lube-free air valve ensures dependable start-up every time. Plus, the compact footprint fits into tight installs. Technicians benefit from easy maintenance. Diaphragms, ball valves, and the air valve can be serviced in-line—no disassembly required. The pump is tolerant of oil, dirt, and moisture, and it won’t freeze or leak under stall conditions. The Balcrank CenterFlo 1120-023A CF15 pump is your go-to for anti-freeze and windshield wash solutions. It performs flawlessly in drums, tanks, and distribution systems.
