ISO 5199 Type 1 & 2 Chemical Pumps - N Series
Amarinth ISO 5199 : 2000 N Series chemical process pumps are designed and manufactured for a number of applications including chemical processing, caustic transfer, condensate extraction and produced water duties. The pumps are typically found in the chemical and pharmaceutical industries, though they can be easily modified for petrochemical applications such as fuel transfer. N Series pumps are designed for low NPSH applications and all have independently verified, full ATEX compliance.
The N Series chemical pumps are designed to be fully interchangeable with a Girdlestone 900 series pumps. They have a removable front suction cover for ease of maintenance plus a two piece lantern / bearing bracket arrangement which helps with interchangeability of parts on site. They are limited to 16 bar g (which is identical to the original Girdlestone pump).
If you are not concerned with every component being interchangeable, Amarinth’s C Series chemical process pump has identical termination points (i.e. suction & discharge flange positions) to the N Series & Girdlestone equivalent pump, but offers a higher pressure rating and other design enhancements.Download Brochure
Using modern computer aided design software the pumps are specifically designed as a heavy duty, minimal wear, long life pump which has be designed in a modular way, with a number of options available, to ensure full compliance to the customers exact requirements and specifications. A heavy duty baseplate helps achieve low vibration and noise levels which in turn extends the pump's life and ensures maximum running time.
The pumps can be fitted with a variety of proprietary components (i.e. seals, motors & couplings) from all the major manufacturers to cater for customers site preferences. Pumps using 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 another manufacturer's seal support system can be fitted.
To complete the package a full range of standard material options from cast iron and stainless steel, to super duplex and hastelloy are available to match your process fluid. NACE & NORSOK compliant materials are also available. Standard documentation packs including manufacturing data books, material certification, installation & operating manuals are available to suit the application. Performance testing to BS EN 25199 / ISO 5199 and various NDE (non destructive examination) & 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.
