FEATURES

The HOMA BR system consists of a robust submersible sewage pump with non-clogging vortex impeller, which primes the water from the deepest part of the tank. Through the ejector, which is flanged on the pump discharge, the jet water will accelerate and cause air to be primed through a vertical pipe. The air-water mixture is pressed with high speed through the ejector pipe parallel to the tank bottom. The combination of jet water and air ensures an effective water movement with high jet intensity and turbulence. For the enlargement of the jet angle, HOMA supplies an optional self swing-ing ejector pipe on request.
