Model 3700 API-610 Process PumpsDesign Features for Wide Range of High Temperature/High Pressure Services
NOZZLE LOADCAPABILITY
Casing/baseplate design
optimized to meet toughest
API nozzle load criteria.
IMPELLER
Multiple closed impellers
for each casing to meet
specific hydraulic require-
ments. Balanced to
requirements of API-610.
CONFINEDCONTROLLEDCOMPRESSION
GASKETSSpiral wound gaskets
assure positive sealing
with no misalignment.
HEAVY DUTYBEARING FRAMERabbeted and metal-to-metal
fits assure runouts and
concentricities well within
limits specified by API-610.
BEARINGSDuplex angular contact
thrust bearings and
deep groove (Conrad)
radial bearings sized
for minimum 3-year life
under severest operat-
ing conditions. Exceed
API-610 requirements.
LABYRINTHOIL SEALSCombination oil
seals/deflectors prevent
oil from leaking and
contaminants from
intruding. Non-
sparking material.
RIGID HEAVYDUTY SHAFTMinimizes shaft
deflection,
extends bearing
and mechanical
seal life.
FINNEDBEARING FRAME
Eliminates need for
cooling water at high
temperatures.
High efficiency finned
cooler available for
extremely hightemperatures.
LUBRICATIONSYSTEM
Proven, engineered
ring oiled flow
through bearing
lubrication for
extended pump life.
SEAL CHAMBEREnlarged, fully conforms to
API-610 and API-682 standards.
Accepts wide range of standard
and cartridge mechanical seals.
