Food Grade Oil Available!

Chemical metering pumps are popular in the food processing industry. They may be used in a wide variety of food processing including mixing ingredients, adding flavoring and preservatives, metering vitamins, and water conditioning. In these applications, incidental food contact may occur, and food grade lubricant oils are best recommended for the pumps.

Aquflow is proud to announce that we offer food grade oil with our metering pumps! Our waterproof and fully synthetic lube oils are biodegradable and do not emulsify with water. Their extreme pressure and low foaming properties make excellent lubricants for hydraulic systems in not only food processing, but also in water and wastewater treatment.

Please contact an AquFlow representative for more detailed information on our available grades.

Global Metering Pump market size to reach USD 4.96 Billion by 2020

The metering pump market size is projected to grow at a CAGR of 6.3% to reach USD 4.96 Billion by 2020. In terms of value, the metering pumps market size in water treatment application is projected to reach USD 1.75 billion by 2020, at a CAGR of 5.9% between 2015 and 2020. The growth is attributed to the increasing demand for environmentally friendly wastewater disposal and increasing investment in modernization of infrastructure.

Diaphragm type metering pumps offer significant advantages over other type of metering pumps and hence, lead the market whereas plunger/piston type metering pumps, due to their maintenance issues and inability to handle abrasive fluids, are projected to register a relatively lower CAGR. Asia-Pacific, with its developing economies and rapidly expanding manufacturing bases, is expected to witness the highest growth market in terms of value during the forecast period.

Selecting the right pump (#3 of 8)

This is the second of eight articles in the series Sizing & Selecting the Right Chemical Metering Pump. Read the previous article “Sizing your chemical metering pump and determining injection rate.”

Unlike most other decisions, this is the most subjective decision to make (unless you have tried various types and brands of pumps). This is also the most consequential decision in determining the level of success with your pump applications. There are many pump types and pump brands available in the market today. Each type and brand of pump has its unique positives and negatives. It is up to the user to choose the right type and brand for their unique application.

It is important to first know that all pump types are divided into two broad types: (1) Centrifugal and (2) Positive Displacement. While centrifugal pumps are the most common types of transfer pumps, they are not suitable in applications where the flow needs to be accurate and needs to overcome high pressures. In the context of chemical metering / dosing applications, a positive displacement pump is used almost all the time. Within the positive displacement pumps, there are many types. Below, we are going to discuss only the most common types used for chemical metering / dosing applications.

1. Gear Pump: As the name suggests, these pumps function by trapping liquid between gear teeth and pushing it from the suction to the discharge port. These are often used for hydraulic pressure developing. However, gear pumps are not suitable for accurate metering applications due to the leak back of liquid depending upon the clearances. These clearances will also tend to increase with wear.

2. Air Operated Diaphragm Pumps:This is a very versatile kind of pump and perhaps the most […]
