Product Description
BETTER could provide a wide range of open type impeller and semi open impeller, casing, stuffing box, wear pad for all series and brands of heavy duty centrifugal pumps, we have improved the original design with hydraulic hole one impeller position, which have prolonged the impellers' life greatly.

All impellers are investment casted or resin-casted with pickling (acid washing) as our power-end parts, which are also available in cast steel in favor of ductile. All other sizes are resin-casted with pickling (acid washing) to ensure smooth surface finish. To ensure quality, we meticulously check threaded holes by fitting their bolts to ensure the threads are clean and clear. All casings are of course pressure tested and all impellers and dynamic balanced. Each casing is properly pressure tested prior to shipping.
It is our standard to deliver all of our impellers in foam molded packing in boxes. If your company has any specific packaging requirements, from branding of castings to box labels, please let us know.

** | Impeller diameter code replaces the XX in the part number | ||||
XX - First X equals' dia. of impeller in inches minus 4. Therefore 13"-4=9, 12"-4=8, 11"-4=7, 10"-4=6, 9"-4=5,8"-4=4,(14"impeller=A0) | |||||
XX - Second X equals fractional data in 1/8's. Therefore 1/8"=1, 1/4"=2, 1/2"=4, 3/4"=6, thus a 10.5" impeller is coded as 64. |
