B) I ALSO WANT TO KNOW IF A CENTRIFUGAL PUMP WITH A TOTAL SUCTION LIFT OF 5M WILL BE SUITABLE FOR THESYSTEM ABOVE IF IT IS TO BE INSTALLED WITH A STATIC SUCTION HEAD OF 3M. C) IN CASE B) ABOVE IS NOT VISIBLE, I WILL WANT TO KNOW THE MAXIMUM STATIC SUCTION HEAD NEEDED FOR THE SAFE RUNING OF THE PUMP. PLEASE NOTE THAT THE SYSTEM IS A NEGATIVE SUCTION SYSTEM. THANKS.
