Pipeline Oil Pumps |
|
Multistage Segmental
|
Designed for transporting crude oil and
refined oil products at pumping temperature up to 80°C through
long-distance pipelines and products lines and can be installed at oil
pumping plants to generate the required head in the long-distance
pipelines to match the system requirements.
Electrically driven horizontal multistage ring-section centrifugal pumps.
Single flow impeller arrangement, with all the impellers facing the same
way.
The pump rotor is carried by the plain bearings with forced oil
lubrication. Shaft sealing: mechanical seals.
The pumping units are made either in the climatic version У (for
areas with a temperate climate), the location category 2 (under roof) at
the lowest ambient temperature of minus 29°C or in the climatic version
УХЛ (for areas with a temperate and cold climate), the
location category 4 (in case of II 500-800, NM 1250-400) according to
ГОСТ 15150-69.

Radially Split Barrel
|
Electrically driven horizontal multistage radially split diffuser barrel-casing centrifugal pumps with a withdrawable cartridge of ring-section type. Single flow impeller arrangement, with all the impellers facing the same way. The pump rotor is carried by the plain bearings with forced oil lubrication. Shaft sealing: mechanical seals.

|
Turbine- or motor-driven horizontal barrel-casing centrifugal pumps with a
withdrawable cartridge of multistage ring-section type. Single flow impeller
arrangement, with all the impellers facing the same way. The pump rotor is
carried by the pressure oil lubricated plain bearings. Shaft sealing:
mechanical seals with external heat exchangers. By providing an inducer
upstream of the first stage impeller a high suction capacity is obtained and
cavitation wear of hydraulic parts is reduced. Pullout construction allows
removal of the rotating element without removing the complete pump.
Major pump components are made of Class S-6 carbon and high alloy steels in
compliance with the international standard API 610 (8th Edition).
Standard schedule of supplies includes a driver, a METASTREAM metallic
membrane coupling, a speed-varying device, a pressure lubrication
installation and an automatic control system. Optional hydraulic torque
wrench is required for tightening nuts for main cover joint.

Double Flow Axially Split
|
Electrically driven horizontal axially split volute casing centrifugal pumps with a double entry impeller. Shaft sealing: mechanical seals. The pump rotor is carried by the pressure oil lubricated plain bearings. The residual rotor axial thrust is absorbed by a angular ball bearing.
Can be used with replacement rotors for partial capacities (50 to 70 per cent of the rated value).
