With a maximum flow of 367 L\/Min and a maximum head of 36 metres, it is suited to high-volume water transfer duties where moderate lift is required.\u003c\/p\u003e\u003cp\u003eThe ZN6 pump end is manufactured from AISI 316 stainless steel, with AISI 316L stainless steel used for the impellers and diffusers. Removable wear rings provide a serviceable hydraulic arrangement, while the Duplex stainless steel UNS S 31803 shaft and replaceable Duplex stainless steel UNS S 32304 coupling form the rotating and motor-connection components. The construction is specified for clean water containing suspended sand up to 100 g\/m³.\u003c\/p\u003e\u003cp\u003eWhen assembled with a C4S submersible motor, the pump end can operate with water temperatures up to 60°C. Hydraulic performance is specified to EN ISO 9906 Grade 3B. The Rp 2 1\/2” (65 mm) threaded connection provides the discharge, while the standard 4-inch NEMA motor connection allows coupling to the C4S motor. Maximum immersion is 300 metres when used with a C4S motor.\u003c\/p\u003e\u003cp\u003eThe discharge arrangement incorporates a microcast ASTM CF-8M (AISI 316 cast) discharge head and lower support, together with an integrated stainless steel non-return valve.
