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
• Fiberglass-reinforced hard integral polyurethane
plastic technology with polyurethane foam core
• Fiberglass-reinforced epoxy composite materials
Motor / electronics
• Long-lasting and reliable high-performance
electric motor
• Direct drive (without gearbox)
• Electronically commutated (brushless)
• Extremely low-wear and highly durable
• Extremely rugged mechanical and thermal char-
acteristics; electronic temperature monitoring
• Direct water cooling for continuous output
• Highly resistant to seawater and watertight; able
to withstand pressure (diving depth 40 m / 131 ft)
• Shaft output up to 2.5 kW (3.35 hp) at 2,000 rpm
• High torque up to 10 Nm
• High overall efficiency including power electron-
ics (more than 90 %)
• Electronic speed control (4 Power Levels in 25 %
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
Drive
Electric jet impeller; low-wear direct drive with guide
vanes stator and diffuser system
Thrust / tractive force:
2.5 kW (3.35 hp): up to 480 N
Batteries
• Aluminium batteries are highly resistant to sea-
water for direct water cooling; encased in water-
tight shell constructed of fiberglass-reinforced
high-grade epoxy composite materials; can with-
stand pressures of up to 12 bar (174.045 PSI)
• Integrated microprocessor-controlled battery-
management system for controlled charging /
discharging and easy operation
