Quality Control Although G-Varadan purchases the highest quality raw materials, our technicians carefully check incoming stock for metallurgical and chemical specifications. We also perform Rockwell hardness tests to confirm the integrity of the materials before the blades are manufactured. Our quality assurance procedure identifies each blade with its raw material source.
Filtering elements are SS 316 wedge wire with openings from 25 microns upwards. The nature of the construction of elements facilitates backwashing and is very rigid to withstand pressures upto 75 Bar with internal reinforcements. Large free passage results in free flow of process liquid and ‘V” design ensures ventury effect during backwash.
Nozzles are specially designed for operation on white water and water with contaminants which are likely to clog the nozzle. Nozzles are available in Needle and fishtail models. Special feature is construction of a rubber diaphragm loaded with spring where the water which passes through the throat is throttled to give a V shaped notch which acts as a needle as well as a flat fishtail spray. If the nozzle is clogged simply lower the pressure to 0.3kgfcm2 which will open the orifice wide and let out the foreign particles. Materials of construction are Brass, SS 304 and 316 qualities.
