DEL-O-FLO™ NOZZLE OFFERS AN ALTERNATIVE

Historically, extra filtration has been the only remedy available for low gallonage Applications. The Del-O-Flo™ nozzle reduces plugging with patented technology that forces particulates and other contaminants through and out the nozzle. “The Del-O-Flo™ contains an extra-fine filter that stops larger particles that cause the problems in low flow situations,” says Delavan’s Stembridge. “The patented Del-O-Flo™ design keeps these particles in suspension and forces them out without plugging.”

ITS ALL IN THE DESIGN

With Del-O-Flo™ Nozzle, fluid flows through the filter into the slots and is metered prior to exiting. The slots are designed to force fluid into a swirling motion where particles are kept in suspension. The nozzle contains short slot openings that are perpendicular to fluid flow. “These short slots keep the fluid from slowing and maintain turbulence, which keeps particulates from collecting, settling, or clogging the nozzle,” says Stembridge.

THE DEL-O-FLO™ PASSES THE TEST

In a test by Delavan engineers, both a standard hollow cone nozzle and an identical Del-O-Flo™ hollow cone nozzle were run continuously for 23 hours in a double adapter using the same oil supply. Clean oil was contaminated with a controlled amount of iron oxide (rust) and sand. Both nozzles had filters prohibiting particles over
40 microns so the contaminants utilized were under 40 microns. At the end of the test, the nozzles were disassembled. The photographs below demonstrate the dramatic difference. Contamination buildup on the standard nozzle was substantial while the Del-O-Flo™ Nozzle remained contaminant-free and clean burning.
