How to Choose the Right Dosing Pump in South Africa

What Is the Difference Between a Dosing Pump and a Metering Pump? The terms are commonly used interchangeably. Both describe positive-displacement pumps that deliver controlled quantities of liquid. “Metering pump” generally emphasises measurable accuracy and repeatability, while “dosing pump” is commonly used for chemical addition in water treatment and industrial processes. PMPS groups these solutions [...] Read More

Safety Features for Chemical Dosing Systems

What makes an industrial chemical dosing system safe? Chemical dosing system safety depends on more than PPE and operator procedures. In industrial plants, safer dosing systems are designed with chemical-compatible materials, bunded containment, safe filling points, ventilation, leak detection, level monitoring, pressure protection, alarms, emergency access and maintenance-friendly layouts. These features help reduce exposure, spills, […]

Metering Pump Accuracy, Stroke Control & Flow Rate

Understanding Metering Pumps: Accuracy, Stroke Control & Flow Regulation In any process where chemicals, additives, or treatment agents must be delivered in precise volumes, a standard transfer pump is usually not enough. A metering pump, often also called a dosing pump, is built for controlled, repeatable delivery. Its job is not simply to move liquid […]
