8. Technical specifications
All specifications are only intended for use in describing
the product. They are not to be construed as guaranteed
properties. The specifications provided here do not repre
-
sent absolute values, since certain deviations may occur
as a result of manufacturing-related tolerances. Specifi
-
cations may be changed without notice to take into ac
-
count new technical advances. As a result, actual product
properties may differ from the ones described here.
Housing
• Fibreglass-reinforced hard integral polyurethane
plastic technology with polyurethane foam core
• Fibreglass-reinforced epoxy composite materials
Motor / electronics
• Long-lasting and reliable high-performance elec

• Direct drive (without gearbox)
• Electronically commutated (brushless)
• Extremely low wear and highly durable compo

tinuous output
• Highly resistant to seawater and watertight; able
to withstand pressure (diving depth 40 m)
• Shaft output up to 5.2 kW / 7 HP at 2,350 rpm
(SEABOB CAYAGO F7)
• High torque up to 22 Nm at 5.2 kW (with excep
-
tionally compact dimensions and low weight)
• High overall efficiency including power electron
-
ics (more than 85 %)
• Electronic speed control (10 power levels in 10 %
increments)
Special motor sealing case
• Multiple-stage sealing rings for redundant seal ef
-
fect throughout the sealing system
• Special rotary shaft seals are mounted in mul
-
tiple stages on a special hard-coated stainless
steel drive shaft for lasting and reliable protection
against water ingress.
• Long-term testing has shown that the use of
optimally matched materials both on the drive
shaft and in the sealing case provides a reliable
means of overcoming the high temperatures cre
-
ated by friction during operation as well as the
strong chemical reactions of the water in the seal
-
ing system occurring when the water is heated
to temperatures of up to 150 °C / 302 °F. This, in
turn, ensures the extremely long operating life of
the device.
• Additional preliminary-stage felt rings designed
to protect the sealing rings from contamination
• Replaceable sealing case for service
