Automatic Top-Up Units

Amarinth Automatic Top Up Units (ATUs) enable the automatic refilling or “topping up” of barrier fluid in API 682 Type 53B seal support systems, maintaining a constant barrier fluid supply at the correct pressure to ensure the seal system continuously supports the shaft seal with minimum maintenance or manual intervention.

Our ATUs are designed and manufactured in-house from 316L stainless steel meeting the demands and time constraints associated with short lead time contracts of less than 22 weeks.

As a world leading pump designer and manufacturer to API 610 11th edition standard, our ATUs are designed to operate and support your unique site specifications, pump configurations, and operating conditions.

Amarinth ATUs meet or exceed stringent customer specifications and restrictive customer vendor lists for all instrumentation, valves and controls, and are fully ATEX compliant.
