Chemical Metering Pump

The Chemical Metering Pump is a positive displacement chemical dosing device with the ability to vary capacity manually or automatically as process conditions require. Approximately 90% of all pumps sold are transfer pumps, which are designed to move liquids from point A to point B. But Chemical Metering Pumps are specialty pumps: They’re designed for precision-injection of chemicals, acids, bases, corrosives or viscous liquids and slurries.

Product Description

1.Product Introduction

For safe and accurate dosing of sulphuric acid,we use PVDF material for the Sulfuric acid dosing pump head. The PVDF pump head and the full PTFE membrane are very durable and ensure that the Sulfuric acid dosing pump can do its job properly and for a long time. This Sulfuric acid dosing pump is also available as a proportional controllable dosing pump (4-20 mA, Volt, Pulse) and as a High Flow dosing pump up to 2000 litres per hour at 3bar. Dongkai Chemical Metering Pump have A rugged design for the toughest challenge. Our Chemical Metering Pumps feature rugged aluminum construction specifically engineered to handle higher output applications in harsh environments. The Chemical Metering Pump is the right choice when choosing a pump for water treatment applications, like coagulation and flocculation. By combining a heavy-duty industrial drive with state-of-the-art design, the Chemical Metering Pump offers a mechanically actuated diaphragm that provides smooth output with reduced potential for system shock and hydraulic oil contamination. External speed control and stainless steel fastenersmake this powerhouse pump perfect for water treatment applications
