BETTER Drilling Fluid Equipment Industrial Limited |
|
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.
We have ductile iron, hard iron, high chrome iron material for
option, if the quantity is ok, we accept to the customized impeller
in bronze, stainless steel and other special material not popular
used.
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.
