Max. negative pressure/vacuum at the pump inlet and outlet. The dosing medium must be bubble-free in pure liquid form. Any necessary adjustments: Suction side: anti-cavitation mode (AK), hydrostatic feed Largest possible hose diameters, short hose lengths On the pressure side: setting valve stroke on pressure side (VD) |

using the anti-cavitation mode (AK) reduces the suction speed of the pump in 3 stages. 25% AK = 5 sec. max. dosing rate approx. 24% 50% AK = 10 sec. max. dosing rate approx. 12% 100% AK = 20 sec. max. dosing rate approx. 6% |
