There are many different types of metering pump accessories. Some of these accessories include: back pressure control valves, calibration cylinders, pulsation dampeners, strainers, inline pressure relief valves, foot valves, and injection valves. Each component is designed to provide improved metering pump performance, and each accomplishes this goal in different ways. Back pressure control valves help maintain constant pressure at the discharge point which in turn maintains a constant fluid discharge.

Calibration cylinders also allow for more optimal metering pump operation. Many metering pumps are originally calibrated under controlled conditions, and it is unlikely that these conditions are maintained in the diverse applications for metering pumps. It is ideal to calibrate each application individually to provide optimal dispensing accuracy. Calibration cylinders allow operators to check the accuracy of metering pumps and adjust dispensing rates as needed. The multitude of other metering pump accessories provide additional benefits mostly focused on improving liquid dispensing accuracy, but also for improved safety and cost savings.

The use of metering pump accessories ultimately leads to improved efficiency, reliability, and performance. In any industry or business, these three qualities are incredibly important. For applications involving the dispensing of expensive chemicals, for example, it is vital that the correct amount of the chemical is dispensed. Too much means increased cost due to wasted chemicals, and too little leads to a potentially low quality product.

Metering pump accessories can provide the added efficiency and performance to overcome these problems. A high performance and efficient metering pump would be able to repeatedly dispense the correct amount of liquid to produce a quality result every time without halting production for alterations. Additionally, valves and dampeners can keep maintenance costs and operation downtime to a minimum, allowing for improved machinery longevity and reliability.
