What are the demands on a centrifugal pump’s performance? How do you handle viscous liquids? What is the best way to minimise noise and vibration? Our Pump Handbook goes beyond the basics of pump design to tackle the details involved in dimensioning pumps and pump systems. Download the guide to get answers to a wide range of technical pump-specific questions.
What is-causes water hammer?
In both situations a partial vacuum is created in the drop pipe. On the next pump start, water moving at very high velocity fills the vacuum and strikes the closed check valve and the stationary water in the pipe above it, causing a pressure surge and hydraulic shock. This shock can split pipes, break joints and damage the pump and-or motor. When discovered, the system should be shut down and the pump installer contacted to correct the problem.

Call the Professionals First When well owners try to service their own wells, they usually fail to solve the problem or make it worse. Qualified professional water well system contractors, like Kocher use specialized equipment, materials, and techniques to keep well systems operational and water supplies safe.
How Does a Heating Pump Work?
As central heating systems age, dirt and metal particles from radiators and pipework break down and begin to flow through major components such as the heating pump. This dirt and grime builds up in major components in the boiler and causes them to fail. Luckily, pump blockages are quite easy to fix, as all it requires is a little bit of cleaning.

When designing a multi-story building, running water is needed on every floor. As a building increases in height, with gravity as the enemy, the ability to pump water to higher levels becomes more challenging. This is an aspect of Architecture, Engineering, and Construction where Grundfos expertise comes into play. As the number of floors increases, so must the size of the piping and power of the pump increase to boost water to the upper floors. Given a number of floors, how big does the water booster solution need to be? How powerful does it need to be?
