Description

High-Pressure and Low-Pressure Dosing Pumps High-pressure and low-pressure dosing pumps are types of chemical dosing pumps used to inject accurate and controlled quantities of liquid chemicals into a process system. These pumps are widely used in industries such as water treatment, chemical processing, pharmaceuticals, food production, and boiler systems. ⚙️💧 1️⃣ Low-Pressure Dosing Pumps Low-pressure dosing pumps are designed to add chemicals into systems operating at relatively low pressure. Typical Pressure Range Up to approximately 5–10 bar (70–150 psi) Common Applications Water treatment plants Swimming pool chemical dosing Agricultural fertigation systems Reverse osmosis (RO) plants for antiscalant dosing Cooling tower chemical treatment Key Features Simple and compact design Lower equipment cost 💰 Suitable for continuous dosing operations Lower power consumption Common Chemicals Used Chlorine Antiscalant chemicals pH correction agents (acids or alkalis) Nutrients and fertilizers 2️⃣ High-Pressure Dosing Pumps High-pressure dosing pumps are used when chemicals must be injected into systems operating under high pressure conditions. Typical Pressure Range 10 bar to over 100 bar (150–1500+ psi) Common Applications Oil and gas pipelines High-pressure boiler systems Chemical reactors Desalination plants Industrial processing lines Key Features Heavy-duty construction 🏭 Accurate dosing even at high pressures Built with strong, corrosion-resistant materials such as stainless steel, PTFE, and Hastelloy Higher power requirements Common Chemicals Used Corrosion inhibitors Methanol for injection systems Scale inhibitors Catalysts
