Metering With ECO Gear Pumps

When choosing a pump for a chemical metering process, the choices often between a diaphragm metering pump or a reciprocating plunger pump with gear pumps are seldom considered. This understanding has grown over the years to the point where the terms metering and reciprocating pump are nearly interchangeable. Whether diaphragm …

Higher Dosing Rates & Steady Flow Metering

Steady flow metering is required in many fluid transfer and liquid dosing applications with various options for dosing additives or chemicals. Processes that require reliable dosing include: Household chemical industry – dosing of detergents and dyes Petrochemical industry – additive dosing of odorants and catalysts Perfume industry – addition of …

How to Choose The Correct Metering Gear Pump

Precision gear metering pumps provide reliable, accurate, and pulse-free metering for many fluid process conditions over a broad range of applications. Many gear pumps provide simple transfer of liquids, while others are designed with exceptionally tight tolerances to provide extremely accurate flow in applications that require precision metering. Precision Gear …

The Advantages of Metering with Gear Pumps

When plant engineers are tasked with selecting and specifying chemical metering pumps, the two common choices that come to mind are either a reciprocating plunger pump or a diaphragm pump. Gear pumps typically are seldom considered as conventional metering pumps have almost become synonymous with reciprocating pumps. Conventional metering pumps, …

Energy Efficient Industrial Water Treatment: Process Equipment Requirements

Industrial water treatment is necessary for many processes such as boiler water treatment, water cooling towers, chemical manufacturing, paints, pulp, and paper manufacturing, and many other applications. Water is a vital natural resource and different industrial uses require different water treatment options based on the process, the water source, and …

How to Achieve Precision, Accuracy, and Flow Rate with Metering Pumps

Diaphragm metering pumps provide precision and accurate dosing to many applications that require consistent flow. While precision and accuracy are very similar definitions referring to the quality of a measurement, they provide different indications. Precision refers to the degree to which a process or instrument will repeat the same value, …

Pumping Sodium Hypochlorite: Chemical Dosing Solutions

Sodium hypochlorite, also known as liquid bleach, remains the number one water disinfectant.  The main concern when sodium hypochlorite is used is ensuring that there are no leaks which can risk dangerous skin exposure. Another concern is the propensity of sodium hypochlorite to cause off-gassing when being pumped. Challenges When …

Case Study: Chemical Plant Solution with Grundfos CR95 BoosterpaQ Pumps

A Midwest chemical processing and distribution company had increased their chemical production capacity with the addition of larger heat exchangers.  This increased capacity put a strain on the aging water system. Maintaining precise temperatures ensures that the chemical reaction yields the highest concentration of a product. The inability of the …
