is self-contained, installation involves connecting the pump to the steering lines and the
electrical control and adjusting the unit to the requirements of the vessel.
2.1.1
Electric Motor
The electric motor is a heavy-duty totally enclosed, fan-cooled unit featuring high efficiency
permanent magnet construction, oversized brush gear with easy access, and standard foot
and face mountings. These motors are available in a wide range of voltages and
horsepower’s
.
The electric control box on DC motors provides for remote start and thermal protection along
with large terminals for easy connection.

2.1.4
Motor/Pump Housing
This coupling interfaces all components of the pumpset as well as provides a stable foot
mount. The unit is machined to ensure accurate coupling of the motor and pump. It houses
the flexible drive coupling, which transfers energy from the motor to the pump. The flexible
drive coupling provides quiet vibration-free alignment. It is constructed of anodized
aluminum.
