Taking the Guesswork Out of Pumpdown Curves

Posted by Tom Bassi on Sep 24, 2015 11:16:48 AM

Everyone knows that keeping track of your vacuum system pumpdown curves is important and a valuable asset in troubleshooting leaks in the system. However, creating pumpdown curves aren’t always easy and can take too much of your valuable time!

3 Key Features Your Vacuum Pump May Desperately Need

Posted by Tom Bassi on Sep 15, 2015 10:00:00 AM

              Vacuum Pumps—the Work Horses of Many Industrial Processes Vacuum pumps are an integral part of many industrial facilities and are used in many chemical processing and manufacturing applications. They are the work horses of vacuum processes and can often be in service 24 hours a day/7 days a week. With proper set-up of your system and timely preventative maintenance, your pump can operate effectively for years to come. You know how important preventative maintenance is, but there are other features like remote monitoring, data logging for tracking and pump down curve creation, and alarm notification that can be easily added to assist you in keeping your processes running without costly interruptions.

Steps for Making Freeze Dryer Troubleshooting Easier

Posted by Tom Bassi on Jul 31, 2015 12:05:23 PM

    A vacuum pump has an important role in Freeze Drying.  If the pump works and your chamber doesn't leak then you've overcome the 2 most common problems and Freeze Drying happens.  If the pump doesn't work, then Freeze Drying doesn't happen.  But what constitutes working?  And if everything seems OK but your process isn't getting to the right vacuum level, where do you start troubleshooting? We recommend starting at the vacuum pump for 2 reasons: It is the easiest thing to quantify and troubleshoot It is the source of your vacuum

PID for Vacuum System Automation

Posted by Tom Bassi on Dec 12, 2014 5:55:00 PM

PID is an acronym for using a closed loop feedback system with the terms Proportional, Integral and Derivative.  While it uses calculus-type words, it is straightforward to configure and is what many industrial processes rely on for predictable automation.  It works on the principal of minimizing the error between the current vacuum reading and the desired set point vacuum pressure.   While PID can work on any closed system, it is also very useful for vacuum systems.  The balancing act is tuning

Using a Vacuum Gauge in Food & Beverage Process Customization

Posted by Tom Bassi on Nov 24, 2014 9:00:00 AM

Removing oxygen in many food and beverage processes is critical.  If this is done manually, the process can be time consuming and result in inconsistent oxygen removal. However, this process can be automated by removing oxygen (O2) via recursive evacuating and backfill cycles.     Automation can be accomplished with

QF/KA Flange Connection Tips For Improved Vacuum System Performance

Posted by Tom Bassi on Nov 21, 2014 12:00:00 PM

Quick-Flange vacuum fittings, known as QF, KF, NW or, in some instances DN, are a widely used flange-type connection system serviceable in rough to medium-vacuum systems. They offer reliable, convenient interconnecting of vacuum components.   QF flange connections are simple to implement.These guidelines will ensure that your system delivers the best vacuum performance:

8 Installation Tips For a Leak Free Vacuum System

Posted by Tom Bassi on Nov 6, 2014 7:00:00 AM

INTRODUCTION: Vacuum sensors that have a threaded interface (e.g., like those found on Model 215v or Model 200) require threaded pipe connections. Threaded pipe connections are commonly used in vacuum sensors, vacuum pumps and rough-vacuum systems. This type of connection can provide economical, reliable service if properly installed. By following a few guidelines you can use threaded pipe to make connections that should be leak free in pressures down to 10 -4 Torr or better. However, low quality pipe and cheap pipe fittings are commonly used in rough vacuum systems, which usually results in unexpected leaks down the road. These leaks are tough to diagnose, and most users will rarely suspect the actual pipe or pipe fittings. This just leads to more downtime, more frustration and more cost. Here are 3 tips on effective sealing:
