Submersible Pump End Feature

Flowserve submersible pumps are multistage centrifugal
units which operate below water level, driven by oil-filled
AC three-phase induction submersible motors.
Pumps and motors form a single enclosed unit when
installed vertically in a water well, which is held in position
by the connected discharge pipe at the non-return valve or
discharge casing.
Flowserve submersible pump units are offered in a wide
range of applications. Pumps are available from 4 in to 48 in
bowl diameters with capacities up to 6000 m3/h (25 000 gpm)
and heads up to 800 m (2600 ft).
Pump units are designed and manufactured to the highest
quality with high pump efficiency and long working life under
the most adverse conditions. They are extensively tested and
inspected to ensure operational safety.
Flowserve pump units are designed on the principle of a
modular structure. Thus, with a limited number of parts,
different tailor-made requests can be achieved. Pumps
are equipped with non-return valves to guarantee optimal
functional safety (water hammer).
Flowserve submersible pump units provide economic
solutions for almost every users requirements.

To produce high-quality submersible pumps and motors

requires both specialized know-how and continually evolving
manufacturing processes. All submersible pump products are
produced using the most advanced manufacturing techniques
from initial development base CAD to quality-controlled
CNC production equipment. It is not by chance that among
experts Flowserve has been a byword for top product
quality for decades.

Advanced Material and Construction

Concept for Pumps
An important feature of the Byron Jackson submersible pump is
the combination of rigid stainless steel shaft construction and extra
heavy bearing design. Double-length, extended life strainer bearings
are sand capped as an added design feature. Additional renewable
heavy-duty sleeve bearings are in each series case. A shaft bearing
is provided on each side of each impeller for minimum bearing span
and maximum shaft support. The long top case bearing provides
additional pump rotor stability.
Standard metallurgy is cast iron bowls, bronze fitted with shaft,
collets and couplings of stainless steel. The pump impeller has
standardized A48 Class 30 castings to ensure reliability of physical
properties and uniform structure. They are also porosity free,
pressure tight and wear resistant.
For special applications, other metallurgies are available.

Submersible Motor
Coupling Motor/Pump

Submersible Motor (Oil-Filled) Description

Byron Jackson three-phase AC squirrel cage induction
submersible motors have been providing successful and
reliable service since 1929. All Byron Jackson submersible
motors are filled with a pure non-hygroscopic U.S. Food
& Drug Administration (FDA)-approved highly refined
mineral oil of superior dielectric strength. This oil is
effectively contained by single or double mechanical seal
arrangements. The oil-filled design provides excellent
insulation with exceptional lubrication fluid corrosion
resistance. These benefits are unaffected by time.

Motor Shaft

Balance Tube

Cable Plug Connection

The specially designed windings for low voltage and high

voltage are insulation class F (155C/311F).

Communication Line

The motor cooling is a perfect environment and designed

by circulation of the continually filtered oil to all internal
motor components. Oil is pumped across both thrust bearing
faces and forced up through the rotor gap. It also lubricates
the bronze radial sleeve bearings and then flows down the
outside of stator lamination through special heat exchangertype passages, transferring heat to the pumped medium.

Motor Windings

Radial Bearings

The rugged stainless steel coupling provides a positive connection between pump shaft and motor. It is designed to transmit
pump thrust in either direction to the motor thrust bearings.

Motor Features
Motor Thrust Bearings

Both up and down pump thrust loads can be continuously carried

by the Byron Jackson precision-machined solid or pivot shoe type
thrust bearing. There is no metal-to-metal contact, as the mirrorlapped bearing surfaces are supported on a film of filtered oil.

Byron Jackson submersible motor efficiency, as published, includes

the thrust bearing losses no further efficiency reduction is required
for this thrust bearing design. Lower thrust bearing face incorporates
exclusive lubrication pockets to reduce start-up friction.

Oil-Filled Submersible Motors With Internal
Forced Cooling System
Internal Forced Cooling System
The internal cooling system was developed with a high-efficiency
cooling impeller. The design provides an efficiently cooling flow
circuit, which ensures sufficient thermal motor reserves and low
cooling losses.

Thrust Disc Cooling Impeller

Single Mechanical Seal

The Byron Jackson single mechanical seal design is used with
the pressurized design motors in hydrocarbon storage caverns
and inclined/horizontal installation water services. The motor
is pressurized from an
external grade mounted oil
reservoir tank, permitting
use of a single mechanical
seal. The operator only
needs to monitor the
oil reservoir for seal
leakage and, in most
cases, can add oil, if
necessary, without
shutting down the
pump/motor.

Double Mechanical Seals

The exclusive Byron Jackson double mechanical seal design
incorporates two separate highly engineered bellows seals, providing
dual protection for the motor. The double mechanical seal system
uses a pressure balance process to equalize the pressure differential
across the seals, minimizing leakage and providing years of
maintenance-free service. The inner seal diverts any pumped fluid
leakage via a communication line to a storage reservoir at the bottom
of the motor, giving maximum protection to the motor windings.

Motor Cable Plug Connection

The exclusive Byron Jackson power cable sealed plug-in-design, with
a replaceable gasket, assures a waterproof connection at the motor
terminals. In addition, it eliminates the need for an untested splice

in the field. The complete power cable assembly can be boxed and
shipped as a separate component, reducing the potential for damage
during shipping and installation.

ANSI/NSF 61 Certificate for the Byron Jackson

Submersible Product
For the North America Market (USA), Byron Jackson pumps and
oil-filled motors are manufactured in accordance with NSF Standard
61. NSF Standard 61 establishes minimum requirements for control of

potential adverse human health effects from products added directly

to water for its treatment and indirectly to water via contact with
treatment, storage, transmission and distribution system components.
