Product catalog summary
Overview: The document provides technical specifications and details for the Lowara Rewindable Motors series, covering diameters from 6” to 12”. These motors are designed for optimal performance, reliability, and ease of installation, with a focus on superior thrust bearing design and bidirectional operation.
Specifications: The motors are available in various power ratings and sizes: 6” (4 kW to 37 kW), 8” (30 kW to 93 kW), 10” (93 kW to 150 kW), and 12” (185 kW to 300 kW). They feature a protection class of IP68, WRAS and ACS approved cables, and a rewindable stator. The motors can operate with variable frequency drives and are suitable for both horizontal and vertical installations.
Technical Features: The motors include a Kingsbury bi-directional axial thrust bearing, designed to handle maximum axial thrust under challenging conditions. They also have a diaphragm for pressure compensation and a pressure relief valve to prevent external water ingress. The maximum immersion depth is 350 meters, and the motors can handle a specific number of starts per hour depending on their size.
Operating Characteristics: Detailed tables provide information on motor types, rated power, voltage, current, and efficiency at rated power. The document includes data for both standard and high-temperature (HT) versions, highlighting differences in performance metrics such as starting torque and nominal torque ratios.
Company Information: Xylem Inc., the parent company of Lowara, is a global leader in water technology, focusing on innovative solutions for water use, conservation, and reuse. The company operates in over 150 countries, offering a wide range of products and expertise in water management.
