Pumps in an anti -bum
The 4-pole series is used to pump clear liquids and sewage. The wide range and high hydraulic efficiency makes this series particularly useful in water, sewage, agriculture and industrial plants, including airports, underground public transport, hospitals and hotels.
Pumps can be used in all wBuchs at risk, in accordance with the CE0477 EPT 1777 7 ATEX 2701 x, ex ii 2g [ex db iib t4 gb, ex h iib t4 gb, 0 ° ° ≤ta≤40 ° available on request.
Characteristic
All main elements are made of gg25 cast iron. Two separate mechanical seals (engine page in the oil chamber, the rotor page in contact with liquid) and high quality parts ensure excellent operation and reliability of the product.
SPECIAL A4 pumps
Specific pumps of the A4 series have a closed single -channel rotor, i.e. a rotor with excellent stamping properties of raw sewage, we only have one channel that limits the stream chapter in the plumbing pump system, which means that fibrous fractions are not able to wind on the rotor. At the same time, the rotor efficiency is much higher than in the case of pumps with a free flight and Vortex rotor.
Installation of the A4 submersible pump
Due to the fact that A4 series pumps are intended for professional applications in most cases, they are installed on the coupling feet DRENO type: AND or B in municipal and industrial pumping stations. For their control, we offer customers advanced control systems with appropriate engine protection and protection against pump damage, such as two independent humidity probes in the engine chamber and the oil chamber, e.g. CR3.1.
We recommend that the selection of a compatible pump with a single -channel rotor is consulted with our specialists to confirm the expected parameters of the pumping station.
Characteristics
- Single -channel rotor closed with a 110 mm flight,
