More about this product
The Ebara CDXHS/I 120/12 is a single-stage, end-suction centrifugal pump in pressed AISI 304 stainless steel, built with Ebara’s optional HS hard-face mechanical seal. Both seal faces are silicon carbide, carried on an FPM (Viton) bellows with an AISI 316 frame and spring. Silicon carbide is far harder than the standard ceramic/carbon pair, so it stands up better to limescale, fine suspended particles and occasional poor lubrication. Hydraulically it is identical to the standard CDX 120/12: 31.2 m head at closed valve and flows up to 160 l/min.
