How Do Pump Check Valves Work?

A pump check valve is a self-actuating, one-way or non-return valve. This automatic safety device allows fluids to flow freely in one direction. However, if the fluid flow is reversed, the valve will automatically close, thus protecting the connected piping and pump.

Booster Pumps Explained

A booster pump is often recommended to increase water pressure to a desired level and improve its flow rate. They are also useful in applications where a single pump cannot deliver the desired service pressure and ensure that other pumps in the system do not cavitate. Let’s find out how booster pumps work and when to use these pumping devices.

What Dual Voltage Ratings Mean for Pumps

Choosing a pump can be confusing if you are unaware of the different pump specifications and categorizations, specifically when it comes to ratings for different voltages (also known as dual voltage pumps).

Centrifugal Pumps Explained

Pumps are mechanical devices that move gases and liquids. While these devices use several different mechanisms to transfer fluids from one point to another, a centrifugal pump is one of the most popular and commonly used pumps in industries to typically transport low viscosity fluids. This guide provides an overview of the centrifugal pump, its working principle, and some of the popular applications to help you select the right pump for your specific fluid transport requirement.

Liquid Pump Lift & Head Explained

There are a number of factors to consider before selecting the best type of pump for an application. Among these are the lift and head capabilities for the desired pump. Lift and head are both used to calculate or rate the movement of liquids vertically as opposed to the flow, that is, the quantity of liquid that a pump can move in a given amount of time. The volume of fluid moved over a given period of time, its maximum flow rate, is measured in gallons per minute, or simply, GPM. That number is not static, however. It is affected by the height that the fluid needs to be pumped. That, in turn, is determined by a pump’s head and lift.
