Maker of nonmetallic sealless pumps has added a 316 stainless steel metallic sealless pump line. The Iwaki Sanwa line will include two series of pumps. Series MP offers flows to 340 gal/min while the smaller Series MMP will be a fractional-horsepower offering with flows to 24 gal/min. Both series incorporate 316 stainless steel construction, a one-piece machined rear casing and silicon-carbide D bearings allowing for limited dry run operation. The stainless steel construction helps ensure the pumps are suited for high and low temperature applications where structural strength is important.
