6SR INSTALLATION EXAMPLE 9 12 8 11 5 4 6 10 ➠ The 6SR series pumps should be installed in boreholes of at least 6” (150 mm) in diameter. The pump should be lowered into the borehole, by means of the delivery pipe, to such a depth (min. 50 cm and at least one metre from the bottom) that it is completely immersed during operation when the level of water in the borehole may reduce. It is good practice to secure the pump by attaching a stainless steel cable to the anchorage points present on the delivery body. 7 STATIC LEVEL DYNAMIC LEVEL 3 2 1 COMPONENTS 1) 2) 3) 4) 5) 6) 7) 8) 9) 10) 11) 12)...
