Three models of our original SPIN-NOZZLE® rotating head design, proven at countless job sites over the years, are still available from NLB. The SRH5-77 is for applications requiring operating pressure of 3,000 psi, 4,000 psi, or 5,000 psi (210 bar, 275 bar, 345 bar). Its balanced steel body accepts two standard nozzles (see below), which are offset to maximize coverage.
| Part Number | Maximum Pressure | Inlet | Overall Length | Diameter | Weight | Speed | Rebuild Kit | Protection Guard |

|---|---|---|---|---|---|---|---|---|---|
| $1 Get a Quote | SRH5-77 | 5,000 psi (345 bar) | 1/4" NPT | 3" (7.6 cm) | 1-15/16" (4.9 cm) | 11 oz. (312 g) | 4,250 rpm | N/A | BN1512 |
To determine flow, select a nozzle size and read across to the column headed by the pressure you wish to use. Expect actual nozzle flow to be about 1 gpm less, as some leakage is needed for lubrication.
