Nelson Irrigation has announced an expanded pressure range for the O3000 and O3030 Orbitor sprinklers. Testing concludes that pressures as low as 6 psi (0.4 bar) are sufficient for proper water application (not to be used at 6 psi with nozzles smaller than #16).

The recommended pressure range is now 6-20 psi (0.4-1.4 bar) for the weighted version and 6-10 psi (0.4-0.7 bar) for the plastic-cover version. This applies to all plate options (blue, black and purple). The throw diameter at 6’ (1.8 m) mounting height at 6psi with #36 nozzle is 46’ for the black plate.The Pivot Orbitor with its unique bracketless design prevents debris hang-up and water pattern misting common to conventional sprinklers and provides outstanding uniformity.
