Senninger Irrigation’s line of center pivot sprinkler products is designed for peak performance at ultra-low pressures of 10 to 15 psi [0.69 to 1.04 bar], and a recommended maximum pressure of 20 psi [1.38 bar]. These low operating pressures offer agricultural irrigators a tremendous opportunity to lower total pumping costs and reduce horsepower requirements, which means irrigators save money, water and energy.
