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.
