In addition to VACUUBRAND's pumps, gauges, and controls, our VACUU·LAN® local vacuum networks are a lab-by-lab alternative to central vacuum systems. VACUU·LAN networks provide deep, stable vacuum in new labs and in renovation projects. Built on VACUUBRAND's durable, chemical-resistant diaphragm…
Be vigilant about parallel pumping conditions that can lead to catastrophic failures During my career, I have seen several massive centrifugal pump failures caused by pump users attempting to operate pumps in parallel without the proper equipment review, procedural review…
Our most recent post addressed the benefits of proportional-only vacuum process control. Though this approach is well suited to many processes, in some cases more accurate (or precise) control of the pressure level is necessary. Under such circumstances, employing PI…
We are officially settled into our new headquarters building located at 2009 Renaissance Boulevard, King of Prussia, PA. We briefly touched on the move in our end of year blog posted Dec. 30th and are excited to report…
In our prior post, we talked about using variants of the classic PID algorithm in order to control vacuum processes. In the simplest form, the PID control loop can be reduced to a P-only, or 2-point, algorithm. For example, by…
Establishing good control over vacuum processes has numerous benefits, such as helping to improve process yields, achieve more repeatable results, and reduce process times. And there are several options for controlling vacuum processes to achieve these various benefits. This post…
DETECTION One of the simplest leak detectors for thermal fluid is the smoke that shows up when the hot fluid is exposed to air. The amount of smoke depends on the size of the leak, the temperature of the fluid and…
In part 1 of this white paper, we reviewed the general advantages of using dry, chemical-resistant diaphragm pumps for process scale-up applications. In part 2, we will delve into the process of configuring the mini-plant in order to realize the…
Introduction Historically, mini-plants have utilized oil-sealed rotary vane vacuum pumps as a vacuum source because they provide relatively high flow rates and because they can reach relatively deep vacuum levels, such as 10-3 mbar. The same can be said of…
VACUUBRAND's dry, chemical resistant pumps provide an ideal solution for use in process development, scale-up work, and kilo labs. With no sealing fluid to replace, our dry pumps provide a low maintenance, low operating cost alternative to oil-sealed rotary vane…
