IP67 high voltage motors for Egypt
Four specially designed IP67 high voltage motors for a water pump station in Cairo were recently ordered by the Egyptian Construction Authority for Portable Water and Wastewater (CAWP).
A special request for IP67 high voltage motors was received from Egypt. Since the Egyptian water pump station of CAWP works with hazardous water, the high voltage motors must be able to withstand a flooding during standstill. As one of the few motor manufacturers who provide special drive solutions, MENZEL has therefore implemented the vertical high voltage motors in the exceptionally high degree of protection IP67. This allows that the four 3,300-volt motors can be simply switched off in the event of an imminent flooding, safely await the water to recede, and then be restarted right away.
The IP67 high voltage motors have been equipped with watertight-encapsulated motor housings and terminal boxes as well as specially designed bearings. Additional gaskets made from special materials were included for each fit, and high surface pressure in all sealing surfaces were then used to achieve a complete sealing that allows these motors at standstill to be exposed to a flooded environment. The use of a non-corrosive material and a subsequent treatment with priming and painting methods to furnish the housing with a very low surface roughness.
The four six-pole squirrel cage motors, each with a power of 740 kW rated power and 990 rpm are now instrumental to help ensure an uninterrupted water supply to the population of Cairo.
IP67 motors with watertight encapsulated motor housings
MENZEL IP67 motors are equipped with watertight encapsulated motor housings and terminal boxes to prevent water penetration and motor damage. Low tolerances, long recesses and the use of perfectly fitting components allow the motors to be flooded at a standstill. As a result, motors with watertight encapsulated motor housings can be restarted straight away as soon as the water subsides.
MENZEL manufactures IP67 motors with squirrel cage or slip ring rotors in a power range from 37 kW to 1,500 kW and for voltages from 380 V to 13,800 V. Common designs of the IP67 motors are IM B3, IM B5, IM V1, IM B35. Like all electric motors from MENZEL, the watertight IP67 motors can be individually adapted at any time and ensure a reliable use under extreme conditions.

High-voltage motors in higher protection classes
As a specialist for industrial drive solutions, we are often confronted with extreme requirements for our high-voltage motors. This is why our motors are also available in higher protection classes, ie beyond the industrial protection class standard (IP55). MENZEL high-voltage motors are also available in the following higher motor protection classes: IP56, IP65, IP66 and IP67.
It is often not easy for plant operators and users to decide which is the right degree of protection for a given industrial application. As a motor manufacturer, it is our responsibility to advise you professionally and to provide the optimum drive solution for your needs. If you have questions regarding the right protection class, please do not hesitate to contact our special department for high-voltage motors.
