ELECTRO SUBMERSIBLE PUMPS
4” AND 6”
|
Submersible multi-stage units with centrifugal impellers of the radial
(PMA – PMB – PMBC – PMC – PMD) and semi-axial (PME – PMH – PMK – PMG)
type in polycarbonate and diffusers in noryl. These materials
are both anticorrosive and nontoxic and provided perfectly smooth surfaces. All stages are complete with anti-wear rings in stainless steel.
Shaft, shell, motor pump coupling, cable shield, suction screen, bushing
and screws are in top quality stainless steel. Bearing in rubber and chromate interchangeable bushing.
Delivery body with 1 ¼” – 2” hole, suction and motor pump coupling body,
can be supplied in brass or stainless steel. Built-in check valve.
All pumps are designed for assembly with 4” asynchronous electric motors
of the two-pole squirrel-cage type in line with NEMA standards, either
three-phase or single stage with permanently inserted capacitor, protection
rating IP-55.
Submersible multi-stage units with centrifugal impellers of the radial
type (MRI B-C-D-E) and mixed flow type (MRI ES-F) and diffuser in noryl;
every stage is provided with anti-wear rings and diffuser body in stainless
steel.

Shaft, shell, motor pump coupling, cable guard, suction screen, bushing,
screws are in top quality stainless steel; and synthesized bearing and
bearing in anti-sand synthetic rubber.
Delivery body with 3” discharge hole and suction motor coupling body
are made of top quality brass. The incorporate check valve is in brass. All pumps are designed for assembly with 6” asynchronous electric
motors of two-pole squirrel-cage type in line with NEMA standards, three-phases,
protection rating IP-55 and the choice of axial loads will make at the
idraulic working conditions. On request, with the adapted suction coupling
body it is possible to assemble, for lower power than 12.5 HP, 4” motor.
These pumps are suitable for both permanent and non-continuous service.
