You know smart design when you see it. Think about ITT. The Impact Wastewater Pump Series is the clear choice for high-efficiency performance in wastewater removal. Impact pumps keep wastewater moving efficiently even in the toughest conditions. Their revolutionary design means impact pumps are ideal wherever waste or drainage must be disposed of quickly and
Centrifugal Pump Readout Corrections – Part 2
Last week the Monday Morning Minute introduced some considerations when using gauge readings to compare with your centrifugal pump curves. Today let’s look at some additional corrections. The vertical axis on the pump curve is the total dynamic head (TDH). When taking gauge readings at the pump tappings provided, we must consider three possible contributors to the
Centrifugal Pump Readout Corrections – Part 1
Last week the Monday Morning Minute article outlined the procedures we use during a check, test, and start-up of a B&G centrifugal pump. After converting from field gauge readings in PSIG to pump head in feet, there are several reasons why the results may be incorrect. The speed of the motor is different than the speed of
Centrifugal Pump Start Up
You specified the best, Bell and Gossett. The contractor purchased the best, Bell and Gossett. Now how do you make sure it is operating the best! Once a B&G base mounted centrifugal pump is installed in your hydronic system we recommend it be commissioned with a specified check, test, and start-up service. This service, when performed by
Accessorize Your Plate Exchangers (Part 2)
Last week the Monday Morning Minutes suggested a strainer accessory for your plate exchanger applications. (Click on past articles to review it) Today we look at three additional options or accessories. INSULATION KITS: On new construction building projects there is normally an insulation sub contractor. There are industrial projects or retrofits where the availability of an insulation
Gasketed Plate and Frame Accessories
Reminder – ITT can provide accessory items with our GPHE heat exchangers. These include Port Strainers, Insulation Kits, Automatic Back-Flush Systems and Drip Pans. Any of these can add value to our product and assist in differentiating against the competition. Earlier this year, you received published pricing and technical information for Port Strainers and Insulation Kits.
Double Wall Plate Heat Exchangers
The Monday Morning Minutes of the last two weeks introduced some differences between plate heat exchangers. Two of the products featured were the double wall plate & frame and double wall brazed plate heat exchangers. We have received many calls regarding these models and Michigan and Ohio plumbing codes. The plumbing code is very specific in its
Not All Plate Heat Exchangers Are Gasketed!
Last week we introduced three varieties of Bell and Gossett gasketed plate heat exchangers. Today, we look at three types of brazed plate heat exchangers. A brazed plate exchanger is a plate exchanger without gaskets or rolled joints. The plates are brazed so there are no elastomers. Brazed heat exchangers are generally available in smaller sizes than
Not All Plate Heat Exchangers Are Alike!
Often times when designing a HVAC or Industrial Process system we use unfired heat exchangers. Our choices vary between shell and tube design or plate/frame design. The next few Monday Morning Minutes will offer a glimpse of the variety of plate type exchangers. Today let’s look at three gasketed plate heat exchanger designs and the application of
Centrifugal Pumps – “Clipping the Tips”
R. L. Deppmann regularly receives questions when a field problem pops up. Here is an example call from an industrial user with a pump issue. There is an existing Bell and Gossett model 1510-5BC with a capacity of 1000 GPM at 60 foot head using a 25 HP, 1750 RPM motor and a 9” cut impeller.
