TANK CLEANING SYSTEMS – BR
Injektor-jet pipe system with submersible pumps for stormwater tanks
CHARACTERISTICS
Tank cleaning systems – BR
APPLICATION
Stream generation: The HOMA Ejector System generates a strong horizontal stream in the tank to keep the solids floating.

MOTOR
Electric motors, with 4-pole motor speed. Insulation class H, degree of protection IP 68. Thermal sensors embedded in the stator winding protect the motor from overheating. PTC sensors on request.
SHAFT/BEARING
Large diameter stainless steel rotor shaft, pre-lubricated bearings.
SEALS
Two independently working silicon-carbide mechanical seals in tandem-arrangement. Oil-filled seal chamber with possibility of control by the inspection screw.
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.
