COSCO
offers a wide range
of submersible pumps
to fit most production
applications. Pumps
are available in production
ranges between 100
and 10,000 barrels
per day with new sizes
regularly added to
the product line.
COSCO
submersible pumps
are the multi-stage
centrifugal type.
Each stage consists
of a rotating impeller
and a stationary diffuser
designed for a flow
rate range. The number
of stages added in
the pump housing determines
the amount of lift
the pump can deliver.
Stage materials are
Ni-Resist (nickel–aluminum-bronze-corrosion
resistant alloy)
K-Monel
shafts are standard
on all COSCO
pumps. Optional high
strength shafts are
also available in
Inconel or Hastalloy.
Corrosion resistant
coatings and ferritic
steel housings are
available for corrosive
applications.
Abrasion
resistant pumps are
available for sandy
wells and for use
where maximum pump
life is desired. Additional
hardened alloy bearings
are added at regular
intervals between
stages in abrasive
resistant (AR) designs. |
