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 …
Ultrafiltration of water is an important process in many industries and applications, treating water for reuse by removing particles and contaminants. Depending on the water source and the ultimate requirement for water quality, industrial pumps and process equipment perform a series of processes such as water intake, aeration, flocculation and …
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 …

Variable frequency drives (VFDs) adjust the pressure or flow on pumps to meet the actual demand. VFDs control the frequency of electricity delivered to pumps and fans. VFDs can provide significant power savings by controlling the rotational speed and frequency of electrical power supplied to the pump motor. VFDs are …
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, …
