Hago 20.00 Gallon Per Hour 80 Degree BPS Bypass Nozzle (200080BPS) Hago 20.00 GPH 80° BPS Nozzle (Spray Pattern Is Semi-Solid) Old Hago Part Number 60478 Rating and Tolerances Flow rates: +/-5% from nominal rating at 100 psi, (~7 bar) operating pressure, with by-pass valve closed. Spray angles: +5°/-0° from nominal rating at 100 psi operating pressure, with by-pass valve closed. Test fluid: viscosity 35 SSU (2.7 cSt) at 100° F. Specific gravity: 0.825 Type BPS by-passing nozzles are designed to produce variable flow rates using a single nozzle. The flow of oil into the swirl chamber of the nozzle is by-passed through a return flow orifice in the nozzle distributor (disc) and a fraction of the flow is returned to the storage tank. When the by-pass valve is closed, the nozzle acts as a simplex atomizing nozzle at its rated capacity. As the by-pass valve is opened, flow through the nozzle orifice is reduced with the balance of the oil returning to the tank. Application and Features Commercial and industrial combustion. Accurate, predictable flow rates. Less than 5° fluctuation in spray angle Turn down ratios between 3:1 and 4:1. Variable flow rate with a constant supply pressure. Fine atomization over entire flow range. Ordering Information: The part number represents the nominal flow rate, the spray angle and the nozzle type Example: 200080BPS = 20.00 GPH X 80° BPS (Bypass Nozzle)
