Unlock the secrets to properly sizing, selecting, and installing chemical dosing systems with our in-depth series, designed to guide you step-by-step. As we all know, chemical metering pump applications are sometimes very complex and require planning and preparation from early on to ensure a successful installation. This series of articles is divided into the following eight sections:
1. Strategic Planning for Efficient Chemical Dosing Systems
Before we even start sizing the chemical dosing systems, it is important to plan the application. We consider various factors such as the chemical, its physical and chemical properties, the storage tank and its location, day-use tank and its location relative to the pump, especially its suction port, the injection quill and its distance from the pump, electrical power requirement, etc.
2. Precision Sizing for Reliable Chemical Dosing Pumps
Here we start with the flow requirements and how much back pressure we encounter in the injection process. We also take into consideration the physical properties such as viscosity and density, and compensate for it. Dosage variation demands are also very important considerations.
3. Selecting the Ideal Dosing Pump for Your Chemical Process
This is where you understand the different choices you have in types and brands of chemical metering pumps and how to differentiate between them. We will also discuss life cycle cost versus purchase price of a pump.
4. Why Choosing Corrosion Resistant Materials is Important for Chemical Dosing Pumps?
Most chemicals are corrosive in nature and they require selection of material that is resistant to chemical attack. Knowing the exact chemical, its temperature and concentration is critical in selecting the right material.
5. Configuring Diaphragm Pumps for Maximum Efficiency and Safety
Do you want a leak detection system? Is the environment filled with flammable gasses or liquids in which case? What type of connections do you need for suction and discharge piping? These are the questions that will be addressed in this section. If these are not properly attended to, it could result in installation delays and wasted money on rework.
6. Advanced Control Systems: Achieving Improved Chemical Dosing Accuracy
Metering pumps by definition need to be very accurate. However, these need to be controlled adequately to maintain the accuracy and repeatability. Will you be controlling manually? Or electronically? Or pneumatically? Would the installation require verification and feedback of the flow? Would the controls need to be local or remote?
7. Dosing Pump Accessories: Critical Accessories for Enhancing Chemical Dosing Pump Systems
Seldom do the metering pumps get used by themselves. Usually they are a part of a larger system. They would need various accessories such as calibration column, back pressure valves and safety relief valves. Without these accessories the chemical dosing systems may not be accurate or durable.
8. Comprehensive Skid Systems for Streamlined Chemical Dosing Operations
Since these pumps are mostly used as a system, it is useful to look at the possibility of buying complete dosing systems from one source. The advantage is that when any component fails or does not perform well, you are not left chasing different vendors who usually blame something else in the dosing systems.
