Description
Pump application: The V 2 pole series is used for pumping wastewater with suspended solids. High productivity makes it useful in a variety of applications, including water treatment plants, industrial plants, agriculture and sanitation.
Feature: all main components are made of GG25 cast iron. Two separate mechanical seals (the engine side in the oil chamber, the impeller side in contact with the liquid) and high-quality parts ensure perfect operation and reliability of the product.
Motor range: 2-pole short-circuited rotor motor; thermal protection T1 and T2, built into the motor winding (connected to a three-pole contactor on the control panel); Class F insulation (155 ° C); degree of protection IP68.
Engine cooling: engine cooling is provided by the liquid in which the pump is immersed.
Limits of use: maximum permissible liquid temperature: 40 ° C with the pump completely submerged; On request, special version (except ATEX) for withstanding liquid temperatures up to 60 ° C with fully submerged pump, without maintenance S1; maximum depth of immersion: 20 m; permissible pH value: 6-10; hydraulic characteristics suitable for liquids with a density of <1.1 kg / dm3; permissible voltage: 220V / 380V ± 5%; permissible frequency: 50 Hz ± 2%.
