Tech Talk: pH Electrode Operation & Replacement

pH Electrode Basics 101

Design & Construction – pH electrodes are constructed from a special composition glass which senses the hydrogen ion concentration. This glass is typically composed of alkali metal ions. The alkali metal ions in the glass and the hydrogen ions in solution undergo an ion exchange reaction, generating a potential difference. In a combination pH electrode, the most widely used variety, there are actually two electrodes in one body.

Iwaki Mag-Drive Pumps: Built to Last

Iwaki Mag-Drive Pumps
Long-Term Performance Champs

The old expression that a chain is only as strong as its weakest link can be easily be applied to non-metallic magnetic-drive chemical pumps also. Most components in the pump end are strong enough to hold up to harsh chemicals and typical wear. However, when there is an upset in the system the weakest link of the chain is exposed.

Tech Talk: How to Read a Centrifugal Pump Curve

If you are new to pumps and fluid processing, reading a pump curve can be a daunting and confusing task. Then just when you think you understand curves, you realize that different types of pumps (centrifugal, positive displacement, air operated diaphragm…) have different types of curves as well. In this post, we’ll break down the anatomy of a centrifugal pump curve.

Pulsation Dampeners Prevent Costly Damage

Plast-O-Matic Series PDS Pulsation Dampeners are a robust solution for combating the damaging effect of water hammer and pulsation. Water hammer and/or unwanted pulsation can cause serious problems and failures in any piping system, leading to costly downtime while repairs are made to piping system components, gauges, pumps and instrumentation. These failures will continue until the root cause is addressed and remedied.

Tech Talk: Water Hammer & Pulsation

The Effects of Water Hammer & Pulsation

Water hammer can seriously damage your piping system.Quick closing valves, positive displacement pumps, and vertical pipe runs can create damaging pressure spikes, leading to blown diaphragms, seals and gaskets, not to mention also destroying meters and gauges.

Liquid, for all practical purposes, is not compressible and any energy that is applied to it is instantly transmitted. This energy becomes dynamic in nature when a force, such as quick closing valve or pump, applies velocity to the fluid.
