Vertical Inline Centrifugal Pump for Fresh Water

Enquiry

Castle Pumps received an enquiry from a new customer in the UK; a civil engineering company who were running an industrial process that included the need to transfer clean, fresh water. The customer reinforced from the outset that the process required the water to remain clean and free from any contaminants, and that the water transfer pump needed to be capable of a large flow rate of 432m3/hr.

Key challenges:

  • Fluid had to remain entirely free of contaminants 
  • High flow rate requirements

Solution

The natural choice of pump when pumping clean, fresh water is a centrifugal pump. As a space saving solution, we specified a vertical inline centrifugal pump from Azcue pumps; a specialist manufacturer of pumps for water applications. 

Due to the fluid being fresh water, we selected a fully cast bronze vertical inline pump; a material which can handle this type of fluid without risk of being corroded. The customer had initially looked at some Epoxy coated cast iron pumps with another supplier, but from experience we know that the Epoxy would eventually wear. Once worn, this would expose the cast iron and result in corrosion and contamination of the fluid which was not acceptable for the customer. 

We coupled the centrifugal pump to an electric 4 pole motor running at 1450 RPM, increasing the lifespan of not only the motor but also the wearing components within the pump. It is important to note that the initial costs for purchasing a pump make up a tiny percentge of the overall running costs. So by fitting a larger motor and running it slower, the customer's overall costs will drop dramatically over the lifespan of the pump.
