What Are the Most Common Causes of Industrial Pump Failure? The most common causes include cavitation, dry running, blocked suction or discharge pipework, incorrect pump selection, misalignment, bearing wear, seal damage, chemical incompatibility and operation outside the recommended flow or pressure range. The complete system should be checked before assuming the pump is defective. PMPS’sindustrial […]

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 […]

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, […]

How do sensors, PLCs, and SCADA improve chemical dosing control? Automated dosing systems use sensors, controllers, dosing pumps, and monitoring platforms to adjust chemical feed based on real process conditions. In industrial and water treatment plants, smart dosing control can improve accuracy, reduce chemical wastage, stabilise treatment outcomes, and give operators better visibility through alarms, […]

PAC & Lime Dosing Systems in Water Treatment: Process Control & Best Practice In water treatment, chemical dosing is not a side process. It sits at the centre of plant performance. Whether the objective is clarification, pH correction, corrosion control, sludge conditioning, or downstream process protection, the way chemicals are prepared, stored, and dosed has […]

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 […]

Industrial Pumping Systems for Corrosive Chemical Materials, Design & Fail-Safes Handling corrosive chemicals is one of the most demanding duties in industrial fluid management. Whether a plant is dosing acid for pH correction, transferring caustic for cleaning systems, feeding oxidants into water treatment, or preparing polymer solutions for clarification, the pumping system has to […]

Chlorine Gas vs Sodium Hypochlorite: Choosing the Right Disinfection Method In water and wastewater treatment, disinfection is not simply about adding chlorine. It is about selecting a system that matches the size of the plant, the skill level of the operators, the site’s safety controls, the chemical supply chain, and the quality targets of […]

What is a polymer preparation system and why is it critical for polymer dosing in water treatment? A polymer preparation system is an engineered unit designed to correctly wet, dissolve, mix and mature polymer before it is introduced into a process stream for polymer dosing or flocculant dosing. In municipal and industrial water treatment plants, […]

What is a hydraulic diaphragm pump system and why is it used in water treatment? A hydraulic diaphragm pump system is a positive displacement dosing solution that uses hydraulic oil to transmit force from a plunger to a flexible diaphragm, which then displaces and meters process chemicals with high precision. In South African water and […]
