Amarinth Offers Scalable Pump Seal Support System ATUs

08 April 2019

Amarinth, a manufacturer of centrifugal pumps now offers a scalable, configurable range of pump seal support system Automatic Top Up Units (ATUs). The units are designed and manufactured in-house and can be completed to meet short lead time contracts.

ATUs enable the automatic refilling or topping up of Plan 53B barrier systems, which maintain a constant barrier fluid supply through the seal system to the pump shaft seal, preventing leakage of the process fluid to the atmosphere. Although ATUs are available from other suppliers, the long lead times of these units (typically 32 to 40 weeks) does not meet many of today’s shorter pump lead times that Amarinth is experiencing, especially with the recent upturn in pump orders being placed by the oil and gas industry.

The ATUs can be completed to suit short lead time contracts, which can often be under 22 weeks, while continuing to meet stringent customer specifications and restrictive customer vendor lists for all instrumentation, valves and controls.

The units can be assembled to suit anything from a single pump to multiple charging pumps. The system is also readily scalable for the length of time the pumps are run. Amarinth has provided ATUs with tanks of working capacities in excess of 300 liters and greater capacities can be achieved within a scaled footprint. Manufactured from 316L stainless steel, meeting or exceeding all standard requirements, the Amarinth ATUs are fully ATEX compliant. Safety is paramount, and the ATUs come as standard with a non-return valve on the feed line to the seal system, pressure control valves to relieve excess pressure and a level transmitter in the tank to warn of low fluid levels.
