Blackmer® Ebsray RC Series RC20, RC25 & RC40 REGENERATIVE TURBINE PUMPS | PRODUCT BROCHURE Where Innovation Flows

Blackmer® Ebsray RC Series Regenerative Turbine Pumps are built for liquefied gases. All liquefied gas, such as LPG and Autogas, applications and installations have unique challenges and issues to overcome – high pressure, low flow, cavitation amongst others. The Blackmer Ebsray RC Series line incorporating the RC20, RC25, and RC40 are up to the challenge by providing fast, quiet, smooth, pulsation-free transfer of liquefied gases in the most challenging pumping conditions. QUIET, EFFICIENT, EFFECTIVE LPG TRANSFER PUMPS Blackmer® Ebsray RC Series – RC20, RC25 & RC40 Regenerative Turbine...

Blackmer® Ebsray RC Series – RC20, RC25 & RC40 | Regenerative Turbine Technology How Blackmer Ebsray RC Series Regenerative Turbine Pumps Work Blackmer Ebsray RC Series Regenerative Turbine Pumps have a rotating, non-contact, free-wheeling impeller disc that has around 60 small cells on its periphery. When liquid enters the suction port it is picked up by the impeller and accelerated around in the narrow hydraulic channel surrounding the cells. Kinetic energy carries the liquid radially around the channel. The spiraling of the liquid many times within one revolution builds energy and...
