Burks Series GNC Base Mounted Centrifugal Pumps are available in 1750 RPM, with capacities to 1100 GPM, heads to 95 feet; and in 3500 RPM with capacities to 950 GPM, heads to 380 feet. The base mounted pump models are rated for use on inlet pressure to 100 PSI and in case working pressures to 200 PSI, with suction sizes from 1 ½” to 5”, and discharge sizes from 1 ¼” to 4”.
Then, an adjacent Flow Hydrant is opened and flow rates are measured at the same time the residual pressure is recorded on the Residual Hydrant. Available GPM at a desired residual pressure (typically 20 PSI) can now be calculated using the Hazen-Williams formula. Fire flow results can then be used to verify a buildings water demand requirements.
