841 Features

Quiet Operation

Operates at low noise levels of 90 dBA (measured from one meter), reducing acoustic interference in various environments.

Precision Vibration Limits

Features controlled vibration specifications: 0.08 in/s for 2, 4, and 6 poles, and 0.06 in/s for 8 poles. These parameters aim to minimize wear and improve operational stability.

Hazardous Area Compliance

Designed for Class I, Division 2, and Zone 2 environments, compatible with sine wave and inverter (ASD) power sources to meet safety and performance standards.

Enhanced Durability

Includes a rust-inhibitive coating system and a corrosion-resistant automatic drain fitting to support use in demanding conditions.

Precise Installation

Engineered with 0.005-inch foot flatness to facilitate stable alignment and potentially reduce vibration during operation.  Verified as part of the quality process.

Ingress Protection

The IP55 robust design effectively prevents the ingress of humidity, dust, dirt, and other environmental contaminants, providing reliable operation even in challenging conditions.

Petrochem Severe Duty

Sealing and Protection

Non-contacting labyrinth seals on both bearings, gasketed main t-box & auxiliary t-box, lead separator gaskets, and corrosion-resistant drain & breather at the lowest part of the motor frame & inside main t-box enhance the reliability and durability by providing effective sealing and protection reducing maintenance and preventing costly downtime.

Insulation System

Designed to withstand an immersion test in accordance with NEMA® MG 1, demonstrating proven resistance to moisture penetration for reliable performance in demanding conditions.

Safety

Grounding is prioritized, with grounding lugs installed on the motor frame and inside the main terminal box. These lugs provide a safe path for stray electrical currents to dissipate into the ground, preventing the motor frame from becoming energized.

Testing and Standards

Adhering to rigorous testing and standards, this series undergoes Non-Witnessed Routine Testing per IEEE 112, verifies efficiency, power output, and operational stability while actively identifying manufacturing defects or inconsistencies early, guaranteeing that only high-quality motors reach the market.
