Drainage & Sewage

During this session you will take a look at the application of drainage and sewage, the theory around both and the benefits of applying pump products to them. You will also cover the selection process and how to make sure you select the right pump for the job.

High Efficiency Pumping

We demonstrate the benefits of High Efficiency pumping systems in achieving energy savings. Variable speed pumps potentially offer 90% energy savings compared to old style fixed speed alternatives. In many cases, proactive replacement of existing installations provides attractive levels of ROI.

Boosting

Multi occupancy buildings and high-rise blocks often depend on reliable booster pump systems capable of a wide range in duty depending on the number of outlets working at any one time.

Pressurisation

Focusing on pressurised systems, we look at how this set-point can be maintained despite leakage or air ingress.

Surge Protection - Designing Out Hydraulic Shock

Hydraulic shock or water hammer can be devastating for water systems and associated equipment. Pressure boosting applications particularly within multi-story buildings are vulnerable to this if the correct steps are not taken. We provide an overview of the cause and offer some potential remedies or design features to limit risk.

Rainwater Harvesting

As we move into a future of Globalisation, Urbanisation and Over Population - how we manage the scarcity of water becomes more of a consideration during the building design process. This unit looks at some of the applications where rainwater utilisation is a viable option.

Expansion & Pressurisation

This CPD details the sizing of expansion & pressurisation equipment, for closed loop heating & cooling systems, in Building, Industry and Datacentre applications, to the EN / BS7074 standards. Highlighting the importance of placing the equipment at the neutral point of the system and explaining the associated terminology, such as “cold fill pressure”.

It highlights the differences between gas cushion and Dynamic (Spill & Fill) expansion systems, particularly the factors that affect the vessel efficiency for gas cushion systems, like the height of the system above the equipment and the fact that Dynamic systems (Spill & Fill) have a far higher vessel efficiency, regardless of where they are placed on a system.

The presentation also highlights the need for an antiflash margin on MTHW systems, keeping the water as a liquid in all parts of the system.

Degassing systems

This CPD outlines the drivers for efficiency in closed loop heating & cooling systems, in Buildings, Industry and Datacentre applications, highlighting the fact that degassed and clean water is one of the best fluids for thermal transfer.

It looks at ways that air can enter a closed loop system, showing how high air content can impact a system - corrosion and associated downtime but also the reduction in the efficiency of the thermal transfer in the water leading to higher energy costs.

With a particular focus on Henry’s law, it shows how modern technologies can be used to degas the system leading to better efficiencies.
