When you use the word vacuum with most people, they think of sucking something up like a vacuum cleaner does. There are times that vacuum condensate systems were used to lift or “suck up” the condensate from a lower level. Today, we will examine the use of vacuum condensate pumps to lift condensate from a low return.
We began a series about vacuum condensate units and introduced one of their uses: the reduction of time to bring a building up to temperature …
Every heating season we get, at least, a half dozen calls with the question above, which is the subject of today’s R. L. Deppmann Monday Morning Minute. Vacuum condensate transfer pumps exist in many older steam heating systems. There were many reasons contractors and engineers used these pumps but most of the systems fall into three categories: time control, temperature control, and condensate lift.
Our Monday Morning Minute (MMM) in September outlined the value and need of using Bell and Gossett triple duty valves in variable speed pumping applications. The use of the triple duty valve ports will make it easier to determine the maximum speed to set in the drive.
Xylem Bell and Gossett recently announced the new System Syzer programs for your computer. You may download these through links on our website at the www.deppmann.com/resources/ page. This new tool has a powerful lineup of useful features. Let’s look at a couple of them. Continued from Part II

R. L. Deppmann is offering another series of seminars, this fall, which are centered on “Energy Savings and ASHRAE 90.1 and 189.1 standards”. During a couple of the first 7 seminars, the question of the air separation location sparked a short discussion. Let’s review the response in this Monday Morning Minute.
Every week a question comes in to R. L. Deppmann about the minimum flow rate through pumps. In hydronic heating and cooling systems, it is …
Bell and Gossett triple duty valves have, for decades, provided a cost effective way to assure there is a non slam check, balance, and shutoff valve on the discharge of your hydronic pump installation. These valves are used to throttle excess head and, therefore, should not be oversized. B&G offers these installation friendly valves in traditional full port model (3DS-S) and in a reduced port version (3DS-B)
