API 610 OH2 Pumps

API 610 OH2 11th Edition Process Pump for the Oil & Gas Industry.

Amarinth API 11th Edition Process Pump A Series petrochemical process pumps are designed and manufactured for a number of applications including LPG, fuel transfer, produced water and export duties. The pumps are typically found in the oil & gas production and refinery industries, though they can be used for other applications such as seawater and condensate duties. A Series pumps are designed for low NPSH applications and all have independently verified, full ATEX Pump compliance.

Using modern computer aided design software the process pumps are designed as a heavy duty, minimal wear, long life pump. Conceived as a modular design, with a number of options available, ensures full compliance with a customer's exact requirements and specifications. A fully API compliant heavy duty baseplate helps achieve low vibration and noise levels which in turn extends the pump's life and ensures maximum running time. A 'space saving' reduced footprint baseplate is also available for use where space is at a premium.

The OH2 Pumps can be fitted with a variety of proprietary components (i.e. seals, motors and couplings) from all the major manufacturers to cater for customers site preferences. Double mechanical seal arrangements can be fitted with a seal support system attached. This can be supplied by Protect System, which is designed and manufactured by Amarinth, or if required another manufacturers' seal support system can be provided for Amarinth to install and fit.

To complete the package a full range of standard material options from SG iron and stainless steel, to super duplex and hastelloy are available to match your process fluid. NACE and NORSOK compliant materials are also available. Standard documentation packs including manufacturing data books, material certification, installation and operating manuals are available to suit the application. Performance testing to OH2 / ISO 13709 and various NDE (non destructive examination) and NDT (non destructive testing) options are offered to ensure full compliance to our customer's specifications. Alternative bespoke packages can be tailored to fit your exact requirements.
