Girdlestone 914 - ISO 5199 Pump

The Amarinth equivalent of the Girdlestone 914 Vertical Long Shaft range of pumps consists of single stage, end suction, centrifugal pumps, robustly designed for wet sump applications. The pumps are of modular construction and as standard can be supplied to suit sump depths of 0.5 to 10 metres, using bearing bush spacings complying with API 610 standards. A wide variety of material and construction options enable pumps to be tailored to suit precise customer requirements.

Practical design features enable routine maintenance to be carried out with minimal downtime. The pump drive end has been designed to maximise access to the thrust bearing, plus vapour seal when fitted, and allow axial adjustment of the impeller from the top of the pump, without the necessity to reset the seal assembly. The drive shaft design incorporates replaceable bearing sleeves, which also function as shaft couplings.

As industry uses an increasingly wider range of chemicals and volatile liquids, vertical long shaft pumps in wet sump installations offer an ideal means of handling these liquids safely and conveniently.

Girdlestone 914 ISO 5199 vertical sump pump- 900 series

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.
