Storm cleaning nozzle
NozzTeq has introduced a new sewer or storm cleaning nozzle called the BL Swiper larger version (patent pending) for pipe sizes from 12 to 30 inches, along with the smaller version for 8-to 18-inch sewer pipes.
The construction of the BL Swiper is made to optimize the cleaning effect by using both the water flow from the jets and air flow in the pipe. The water flow, through the pressure in the jets, creates a jet stream and the jet streams create thrust through a number of air channels. The number of air channels is equal to the number of water jets, i.e. a nozzle supplied with six water jets are supplied with six air channels. The channels are placed in the centre of the nozzle meaning that the total force generated by the nozzle, both air and water force, are used to clean the pipe in cost effective manner.
Tests performed with the BL SWIPER have determined that the flow rate can almost be cut in half, compared with normal flow needs. The pressure has a direct impact on the cleaning ability of the larger/smaller BL Swiper.
