With so many pumping technologies and pump types, how do you know that you have the right pump for your process? Castle Pumps have extensive product knowledge and know typical scenarios where getting the wrong pump can result in expensive downtime and imperfect product. Read the article to learn more about how you can avoid these typical issues and select a more efficient pump that fit your process.

Labour costs are one of the most expensive overheads in any company. So are your engineers spending more time than necessary on operating the pump? If, so it is time to consider automating your pump and freeing up your employees' time for more value-added tasks and making your process more efficient. Read our article and find more about how you can automate your pump and how your process can benefit from pump automation.

When selecting a pump, businesses are often faced with budgetary pressures, which affect their decision and make them choose not the most economical solution in the long term. Considering the upfront/initial costs without understanding the future running costs is a common mistake. To make sure you are buying a pump with the lowest long term cost, read this article and find more about the total life cycle cost of a pump.

The environmental impact of activities, products and services is measured and monitored now more than ever, especially within the marine and industrial markets. This along with the ever increasing need to reduce costs, means energy efficiency is an important factor - especially where your pumping system is concerned. In this article we discuss 7 ways that you can improve the energy efficiency of your pump...

Pump curves are essential during the decision making process, as they provide the information you need in order to see whether the pump will perform how you need it to! In their most basic form, performance curves contain flow rate and pressure data. Being able to read a pump curve enables you to choose the right pump, rather than choosing one that could potentially cause damage, consume unnecessary energy or perform poorly.

Head loss is an essential part of the preparation of looking for a pump with specific requirements. These head losses - also known as pressure losses - are sustained by the fluid as it flows through the pump and therefore can affect the pumping operation. Being such an important factor when making the decision on which pump to purchase, we have created this section for you to calculate the head loss within your application.

If you operate, maintain or specify centrifugal pumps then you will likely have heard of a pump curve. However, what many misses to consider is the best efficiency point of the pump they are selecting, which can result in costly maintenance and downtime. So, read this article and learn more about what BEP is and what happens to your pump when you operate it too far left/right of the pump curve.

Ever wondered why you can't just have a pump that's suitable for all fluids? Well this article will explain why, and it's all down to chemical compatibility! One of the first questions you'll be asked when sourcing a pump, fitting or pipework is 'what fluid are you handling?', and this is because the fluid will determine what material the pump needs to be made of to avoid corrosion, damage and failures!

Doing a fluid compatibility check when sourcing a pump is one of the first things you need to think about! Certain fluid/material combinations can result in corrosion, swelling, brittleness, leaking and even the dissolving of the pump! So ensuring you have the right pump material for the fluid you want, is a must! This fluid compatibility table will give you the information you need to determine which material will suit your fluid best.

When specifying a pump for oil, we'll need to check what type of oil you'll be pumping. Viscosity is critical for pump selection, and with so many different types of oil it's no surprise that the range of viscosity can vary from oil to oil. Confirming the viscosity of the pumped medium will put you on track to getting the right pump for your application, and this article will explain in depth why knowing the viscosity is so important!

There are a number of differences between cast and pressed metals, but do you know how they could affect your decision when buying a pump? This article explains in depth what each type means as well as the pros and cons, so that you know which bits of information you should take into account when deciding on the best pump for your individual process at hand.

There are two main families of pumps; positive displacement and centrifugal pumps, both of which have their uses and best areas of application. It is important however to be able to identify when each pump type should be selected, which ultimately comes down to their working principle and the application at hand. This guide talks through those differences and gives examples of when one is more suited than the other.
