ISO 5199 Type 1 & 2 Chemical Process Pumps - C Series

Amarinth ISO 5199:2000 C 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. C Series pumps are designed for low NPSH applications and all have independently verified, full ATEX compliance.

Using modern computer aided design software the 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 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 and 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 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 BS EN 25199 / ISO 5199 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.
