It reaches a maximum head of 257 metres while maintaining the 367 L\/Min maximum flow.\u003c\/p\u003e\u003cp\u003eThe pump end is constructed in AISI 316 stainless steel, with AISI 316L stainless steel impellers and diffusers incorporating removable wear rings. A Duplex stainless steel UNS S 31803 shaft supports the rotating assembly, and the replaceable coupling uses Duplex stainless steel UNS S 32304. The construction permits suspended sand up to 100 g\/m³.\u003c\/p\u003e\u003cp\u003eWith an L6W motor, operating water temperature is limited to 35°C. Hydraulic performance is specified to EN ISO 9906 Grade 3B.
