The Relationship Between Stroke Rate and Pulsation — And Why It Matters Downstream
Every stroke of an AODD pump delivers a discrete pulse of fluid. This is not a defect — it is the fundamental operating principle of any positive displacement pump. But pulsation is also one of the most overlooked sources of process problems downstream, and the stroke rate you set has a direct and predictable effect […]
When Viscosity Affects Dosatron Accuracy — And What to Do About It
The Dosatron’s technical documentation is consistent on one point: dosing accuracy is maintained independently of variations in flow rate, water pressure, inlet height, and temperature. These are real advantages over other injection technologies, and they hold true in practice. Viscosity, however, is listed separately — and for good reason. At elevated viscosity, Dosatron dosing accuracy […]
Dosatron Dosage Range Selection: Why Getting This Wrong Is Worse Than Getting the Flow Rate Wrong
When engineers select a Dosatron model, the first number they look at is the flow rate range. This makes sense — the Dosatron must be able to handle the volume of water flowing through the system. But the second selection — the dosage range — is where most specification errors happen, and the consequences of […]
Dosatron External Injection (IE): When It Is Mandatory, Not Optional
The Dosatron product range includes models with standard internal injection and models with external injection, designated IE. To most buyers, this looks like a minor configuration option. In some applications it is. In others, specifying the wrong option damages the pump, shortens its service life, and introduces contamination risks that the operator cannot see until […]
Dosatron vs Venturi Injector: Why the Operating Principle Changes Everything
Both a Dosatron and a venturi injector are water-powered chemical dosing devices. Both install inline in a water line. Neither needs electricity. At a glance, they appear to solve the same problem. They do not. The operating principles are fundamentally different, and those differences determine accuracy, reliability, and which applications each device is actually suited […]
The Problem a Dosatron Solves That Manual Chemical Preparation Cannot
In any process that requires mixing a concentrated chemical with water at a consistent ratio, the manual method has an inherent problem: it depends entirely on human accuracy, every single time. This is the problem a water-powered dosing injector like the Dosatron is designed to solve — not by replacing human judgment in complex decisions, […]
The Three Things That Actually Determine Your Crop Yield — And How to Control All of Them
Most farmers know when something is wrong with their crops. The leaves tell you. The soil colour tells you. The yield at harvest tells you. The problem is, by the time any of these signs appear, the damage is already done. What precision agriculture offers is not a better way to react to crop problems. […]
Why Stroke Rate Matters More Than You Think When Dosing Viscous Chemicals
Most engineers size a metering pump based on two things: the required flow rate and the discharge pressure. These are the right starting points. But for viscous chemicals, there is a third variable that determines whether the pump actually delivers what the datasheet says it will — stroke rate. Get the stroke rate wrong for […]
