In large projects where the pump energy is only a fraction of the total energy consumed, it has often resulted in over-sized pumps based on worst case conditions where in many cases were never encountered. Too often a pump or pump system was sized based on a design condition that was at or very close to a particular pumps highest efficiency. What may not have been considered at the time was the duty cycle and how far off that point of highest efficiency the pump or pumps would actually be operating.

Entrained air is one of the most persistent problems that plague hydronic heating systems. It is also one of the least understood. This webinar will help you understand why air elimination is critical for proper system function, how air problems develop, and how to rid the system of them. In addition to an exploration of air separation devices, it will give practical advice on system design and a process for effectively eliminating air from your hydronic heating system.

Participants will learn:

Dosing pumps, also known as metering pumps, provide accurate liquid chemical feed into a fluid that is to be treated. This webinar will introduce you to the basic concepts that lead to improved process control, high flow accuracy, and effective handling of hazardous and expensive chemicals in an almost endless variety of markets and applications.

Participants will receive a certificate to submit for CEU credits!

Given the wide variety of pump choices, how do you decide which type to use in the first place? This free webinar will give insights into how to make that critical decision when specifying pumps for nonresidential HVAC applications. Whether a frame-mounted or close-coupled end-suction, horizontal split-case, vertical turbine, submersible, circulator, vertical multi-stage, or other pump type, this educational session will help attendees choose the most appropriate and optimal pump type for the job. This is not a course on how to select pump sizes and optional features.

With more focus on energy efficiency these days, owners will rely on pump experts to assist in the determination of efficient pumping solutions. For variable flow systems this poses some challenges when single and parallel connected variable speed pumps are evaluated. This webinar will help to answer questions like: “How many pumps should our system use?” and “How should we sequence (stage) on additional pumps?”

This 1-hour webinar will teach you how to read a pump curve and how to use that information to:

• Select and size pumps and drivers
• Understand power consumption strategies
• And more
