 GNXP-CHP  is designed to handle severe plugging. The standard casing, made of ASTM A536 grade 65-45-12 ductile iron, stands up to robust applications. Everything about the pump is built to tackle hard jobs, from the replaceable cutter bar made of T1 tool steel heat treated to a minimum of 60 Rockwell C hardness, to the heat treated cast steel impeller. The Primevacmach Chopper pump series is a heavy-duty performer.

CD4MCu Pumps

CD4MCu is a stainless steel with corrosion resistance equal to or better than 316 SS, but with double the yield strength. It’s a duplex (two phase) stainless steel, while common grades of stainless steel, such as 316, are single phase. This provides the corrosion resistance of 300 series stainless steel with the strength and hardness of 400 series stainless steel. CD4MCu allows pumps to be used in more abrasive applications with better resistance to corrosive cracking and pitting.  Features include:

  • Corrosion and pitting resistance
  • Higher strength than standard grades of stainless steel
  • Improved ductility and weldability
  • Better resistance to embrittlement
