Exdb flameproof protection with IIB gas group enhances safety in potentially explosive atmospheres, reducing the risk of ignition during motor start-up and operation. Business impact: safer operation lowers downtime, incident risk, and insurance costs. Application: suited for pumps, mixers, and conveyors in chemical and petrochemical plants where explosion protection is mandatory. IE4 efficiency delivers substantial energy savings across continuous processes; business impact: lower running costs and improved sustainability; application: large-scale fans, pumps, and grinding mills in harsh environments. IP55 protection combined with ICFL insulation supports reliable performance in dusty, humid, or outdoor installations; business impact: extended service life and reduced maintenance cycles; application: mining, cement, and process plants with aggressive ambient conditions. The 355 frame, cast iron housing, and 6-pole design provide rugged durability for high-torque start-ups; business impact: fewer unscheduled outages and longer mean time between failures; application: heavy-duty drives in hoisting, filtration, and material handling. Direction of rotation on both sides and S1 duty enable versatile installation and continuous operation; business impact: simplified system integration and dependable process control; application: multi-point line shafts and circulating systems in hazardous zones.

FAQs
Plan for a 1834 mm length, 746 mm width, and 1124 mm height footprint with a 2646 kg weight. Mount with the D-End top terminator box location and ensure adequate service clearances. Verify IP55 protection, Exdb flameproof certification, and IE4 efficiency. Use appropriate hazardous-area supports, proper ventilation, and torque alignment for six-pole operation.
IE4 efficiency indicates top-tier synchronous performance, with full-load efficiency around 97.0–97.1% at 50/60 Hz, translating to lower energy consumption during continuous duty. The improvement reduces electricity bills in pumping, fans, and conveyors, while also decreasing heat generation and cooling loads in constrained plant spaces.
Yes. It features Exdb flameproof protection, IIB gas group suitability, IP55 enclosure, and IC411 insulation. The 6-pole, 355 frame, cast-iron housing and S1 duty support continuous operation, even in dusty or humid chemical environments, making it well-suited for hazardous-area pumps and process equipment.
The motor is certified for Exdb flameproof protection and IP55 ingress protection, with IC411 insulation and IE4 efficiency data. Gas group IIB designation aligns with hazardous-area requirements. Direction of rotation both sides and S1 continuous duty further support regulatory compliance in demanding industrial installations.
Expected ROI comes from energy savings (IE4), reduced downtime due to robust cast-iron construction and high-quality bearings (6322/C3, 6316/C3), and longer service life in challenging environments. Maintenance focuses on bearing health, alignment, and insulation integrity, while the flameproof design minimizes ignition risks in hazardous zones.
