A characteristic that distinguishes the model f , is certification for compliance with the ATEX standards, which allows them to be used where the usual submersible pump could not be used due to the explosion hazard of liquids or the environment. = "Box-Sizing: Border-Box; Color: RGB (119, 119, 119); Font-Family: Arial, Sans-Serif; Font-Size: 20px;" />
Each component, from cable to fasteners, meets the requirements of the highest safety to eliminate the danger of applying in a potentially explosive atmosphere.
These pumps can be equipped and intended:
- Vortex impeller (dgf ) with a large free passage, which is recommended for use by with contaminated liquids ;
- multi-channel open (DRF ) , intended mainly for ups pure or poorly contaminated liquids ;
- Grounder (GRF) , suitable for drains containing fibers and threaded substances ;
- for Great pressure ( APF) , in the use of water containing weighted sand , and abrasive bodies .
Mechanical seals are located in a large examined oil chamber that guarantees durability. < Br Style = "Box-Sizing: Border-Box; Color: RGB (119, 119, 119); Font-Family: Arial, Sans-Serif; Font-Size: 20px;" />
In the oil chamber, by order, a sensor can be installed, which is connected to the properly prepared electric shield and is able to signal the penetration of water as a result of wear of external mechanical seal, which allows you to replace it and protect the engine.
At the end of the line, each model passes double tests to check the tightness of the motor compartment and the correct installation of mechanical seals, which are a guarantee of high reliability.
