20 Years Supporting Motor Rewinders with Seal Identification & Specification
Motor rewinders are under constant pressure to deliver fast, reliable repairs without compromising quality. When pump suppliers don’t understand rewinding realities, it leads to delays, incorrect parts, repeat failures, and costly call backs. With over 20 years working directly with motor rewinders, we understand the pressures you face, and how to remove them.
Newark Electric Motors (NEM) is an established and respected rewinding business. They could choose any supplier – but 20 years on, they still come to us first. Being local helps. They drop damaged seals into our trade counter for immediate identification, keeping their repairs moving.
“5 Stars! Top Rate Service. Very knowledgeable.” – Newark Electric Motors
Two recent examples show how we work:
Challenge 1 - Flygt spare with minimal information.

The problem. Newark Electric Motors customer needed to source a Flygt mechanical seal. The only information provided was the physical seal and that it was used in dirty water pumping. The unusual size and material made matching tricky.
Our Solution:
» We measured and analysed the seal
» Cross referenced our spares database
» Found a suitable third party replacement
Result: Newark Electric Motors could complete the repair without delays, saving time and reducing downtime.
Challenge 2 - SPX Flow seal with repeated failures

The problem. Newark Electric Motors brought in a SPX Flow pump seal which was failing repeatedly. The problem lay with the wrong elastomers and wrong seal faces. Their customer had simply had enough.
Our Solution:
» Assessed the seal and operating conditions
» Recommended a Silicon / Silicon / Viton material combination better suited to the chemical being pumped
Result: A long-term fix that improved reliability and reduced future failures.
Partnering for Success
From identifying unknown seals to solving recurring failures, our goal is simple: help motor rewinders work faster, reduce rework, and deliver reliable repairs.
Whether you need part matching, application advice, or pump support, we provide technical backup when you need it.
