Description
Pump application: the 4-pole a series is used for pumping clean liquids and wastewater. The wide range and high hydraulic efficiency make this series particularly suitable for water treatment plants, sewers, agricultural and industrial enterprises, including airports, underground public transport, hospitals and hotels.
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: 4-pole short-circuited rotor motor; thermal protection T1 and T2 integrated in the motor winding (connected to the 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%.
