duty requirements
Review water, grit, debris and maximum particle description, required flow and total head, suction lift, suction-line length and air leakage risks, operating cycle and priming requirements, drive, portability and service access together with the liquid composition, temperature and installation. The values on a catalogue page are not a substitute for checking the selected model curve and approved arrangement.

applications
For construction dewatering, check the applicable product curve, liquid properties, required operating point and installation geometry. Check the proposed arrangement against surface mounting with a sealed suction line and cleanout access and wear materials selected for debris, grit and water chemistry, then verify the operating point on the selected model curve.
For mining pit drainage, confirm the operating liquid levels, mounting geometry, immersion and removal access. Check the proposed arrangement against surface mounting with a sealed suction line and cleanout access and wear materials selected for debris, grit and water chemistry, then verify the operating point on the selected model curve.
For temporary water bypass, check the applicable product curve, liquid properties, required operating point and installation geometry. Check the proposed arrangement against surface mounting with a sealed suction line and cleanout access and wear materials selected for debris, grit and water chemistry, then verify the operating point on the selected model curve.
