Efficient Liquid Metering: API 675 Approved Diaphragm & Proportional Dosing Pumps

by | Mar 30, 2023 | Pulsafeeder

Accurately measuring and delivering liquids is critical in many industries, including chemical processing, water treatment, and oil and gas. Liquid metering pumps provide a reliable solution for these applications. In this blog post, we will explore two types of liquid metering pumps that are widely used in industry: API 675 approved diaphragm metering pumps and proportional dosing pumps.

Metering Pump

Before we dive into the specifics of these two types of liquid metering pumps, let’s first define what a metering pump is. A metering pump is a type of positive displacement pump that delivers precise amounts of liquid. Metering pumps can be used for a variety of applications, including injecting chemicals into a process stream, adding flavors to food products, and dosing medication in healthcare settings.

API 675 Metering Pump

API 675 is a standard set by the American Petroleum Institute (API) for positive displacement pumps used in the oil and gas industry. API 675 approved metering pumps are designed to meet strict performance and reliability standards. These pumps are commonly used in applications such as chemical injection, well stimulation, and pipeline transfer.

Hydraulic Diaphragm Metering Pump

Hydraulic diaphragm metering pumps are a type of API 675 approved metering pump that use a hydraulic system to move the diaphragm that meters the liquid. These pumps are ideal for applications that require high accuracy and consistent flow rates. Hydraulic diaphragm metering pumps offer several benefits, including:

  1. High Precision: Hydraulic diaphragm metering pumps offer high precision and accuracy in liquid metering.
  2. Corrosion Resistance: These pumps are often made from materials such as stainless steel and titanium, which are resistant to corrosion.
  3. Low Maintenance: Hydraulic diaphragm metering pumps are designed to require minimal maintenance, reducing downtime and costs.

Diaphragm Metering Pump

Diaphragm metering pumps are another type of metering pump that are commonly used in chemical processing and water treatment applications. These pumps use a flexible diaphragm to meter the liquid, which is moved by a mechanical linkage or a hydraulic system. Diaphragm metering pumps offer several benefits, including:

  1. Versatility: These pumps can handle a wide range of fluids, including corrosive and abrasive liquids.
  2. Consistent Performance: Diaphragm metering pumps offer consistent performance and flow rates, even when pumping difficult fluids.
  3. Low Operating Costs: These pumps require minimal maintenance and offer low operating costs, making them an ideal solution for long-term use.

Dosing Pump

Proportional dosing pumps are a type of metering pump that offer the ability to adjust the flow rate of the liquid being pumped based on changing process conditions. These pumps use sensors to monitor the process stream and adjust the flow rate accordingly. Proportional dosing pumps offer several benefits, including:

  1. Precise Control: Proportional dosing pumps offer precise control over the amount of liquid being delivered, ensuring accuracy and consistency.
  2. Energy Efficiency: These pumps are designed to operate at varying flow rates, reducing energy consumption and operating costs.
  3. Reduced Waste: Proportional dosing pumps help reduce waste by accurately metering the amount of liquid needed for a given process.

In conclusion, liquid metering pumps are essential components in many industries, providing accurate and consistent liquid delivery. API 675 approved diaphragm metering pumps and proportional dosing pumps are two popular choices that offer high precision and reliability. When selecting a metering pump, it’s important to consider factors such as the type of fluid being pumped, the flow rate requirements, and the specific process conditions. With the right metering pump, businesses can achieve efficient liquid metering, ensuring the precise delivery of chemicals, flavors, and medications. Whether you need a hydraulic diaphragm metering pump, a diaphragm metering pump, or a proportional dosing pump, there are a variety of options available to meet your specific needs. By choosing a high-quality, reliable metering pump, businesses can improve process efficiency, reduce waste, and ultimately save time and money in the long run.
