The consistent and precise dosing of pharmaceutical agents during laboratory testing is critical for the development of new medications. Liquid pharmaceutical agents tested in laboratory subjects must be precise to determine the accurate influence of the agents and to reproduce consistent, precise dosing. One of the greatest obstacles to repeatability …
Mass vs Volume Mass and volume are two units used to measure objects. Mass is the quantity of substance an item possesses, whereas volume is the amount of space it occupies. A simple example would be to compare a basketball to a bowling ball – each has about the same …
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 …
Increase costs as setting up, operating, and evaluating pilot plant test results can be an expensive process. Improving the accuracy and efficiency of data collected improves final plant design and saves a considerable amount of money.Pilot plants serve a very important purpose to help make the right decisions for the …
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 …
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 …
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, …
The steel industry is a harsh environment where all equipment is exposed to intense heat and must operate reliably to prevent dangerous situations. Part of the steel finishing process includes pickling, which is a method of removing impurities from steel such as inorganic contaminants, scale, rust, stains, aluminum alloys, and …
Boiler feed systems rely on pumps and sensors to control and maintain the water level in the boiler. Various sensor technologies are available to achieve this each with different advantages and disadvantages. Choosing the correct method to control boiler system water levels is important to optimize economic operating efficiency. Variable …
Metering pumps move a specific volume of liquid in a specified period of time, often giving users the impression that this provides an accurate amount of pumped volume. When using a gear pump, users can see improvements in accurate flow by using a flow meter. Metering Pump Accuracy Depends on …
