This is ensured through these features: Watertight cable connection(The hermetically sealed polyurethane-filled, stainless steel cable plug connection ensures that no liquid will penetrate through the cable into the motor.) Short motor shaft(Compact construction with short shaft outside bearings ensures less stress on bearing and, consequently, long lifetime) Stainless steel clamp(Unique clamp system enables quick and easy dismantling of pump and motor unit. No tools required. Enables 180 rotation of motor housing) Cast iron flange and feet(Feet on the pump housing provide protection of the grinder system. Additional feet extensions can be fitted to ensure sufficient free suction and to prevent clogging or jamming.) Specially designed lifting handle(Ensures correct lifting regardless of installation or motor positioning.) Motor protection(Built in thermal switches in the motor windings provide protection against overheating. Ensure long time.) Heavy-duty ball bearings(The heavy duty, maintenance free ball bearings are greased for life. Single-row ball bearings in pumps with 0.9kw to 1.5kw motors.) New, efficient grinder system(Patented grinder system ensures extremely high efficiency and reliable operation. Quick and easy dismantling for replacement of wear parts. No special tools required.) Smart trim impeller adjustment(Patented smart trim system enables quick and easy impeller clearance adjustment in order to maintain peak performance. Can be done without dismantling the pump. No special tools are required.)
