Submersible Pumps

A·AH Series
The Multi-vane Semi-open Impeller
Yield High Efficiency
There are MANY ADVANTAGES with ShinMaywa Submersible Pump.
●Features and Construction

Cable entry Motor protector

This cable entry employs A bu i l t - i n a u t o m a t i c -
a core seal that effectively reset type motor protector
prevents water from (thermal protector)
wicking down the cable positively protects the
eve n w h e n t h e c a bl e motor from burnout due
end is immersed or the cable sheath is to overload, impeller clogging and open
damaged. This feature prevents water phase.
from penetrating the motor chamber.

Shaft seal Motor

A highly wear resistant Air-filled type motor with class E (or class
silicon carbide double F) insulation is employed.
mechanical seal positively
prevents the water from
penetrating into the motor
chamber. Besides, combined use of an
oil seal further extends the service life of
the mechanical seal. Impeller
The multi-vane semi-open impeller yield
with high head and improved pump
efficiency.
Discharge connection
When the guide rail installation type
submersible pump is lowered along the
guide pipe, the pump is automatically
connected to the discharge pipe with the
discharge connection.
