Description
Pump application: The VTH 2 pole series is used for pumping sewage 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.
Range of motors: motors with a short-circuited rotor 2 poles; 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 when the pump is fully submerged; on request, special version (except ATEX) to withstand liquid temperatures up to 60 ° C with the pump fully submerged, maintenance-free S1; maximum immersion depth: 20 m; permissible pH value: 6-10; hydraulic characteristics, suitable for liquids with a density <1.1 kg / DM3; permissible voltage: 220v/380V ±5% depending on the pump; permissible frequency: 50 Hz ±2%.
