ProMixUSA pump calibration columns, also known as calibration cylinders, offer a precise and straightforward method for determining pump flow rates, using industry-standard graduations in milliliters per minute (ml/min) and gallons per hour (GPH). These columns are essential tools in various industrial applications, providing accurate measurements that ensure optimal performance and efficiency of pumping systems. This comprehensive description will explore the features, benefits, and applications of ProMixUSA pump calibration columns, with an emphasis on their construction materials, readability enhancements, and protective features.
Function
The primary function of these calibration columns is to measure pump flow rates accurately. Each column is designed with top-aligned graduated scales that allow operators to monitor both ml/min and GPH in a single, one-minute test. This dual-scale feature is particularly beneficial for users who need to switch between different units of measurement quickly and effortlessly. The top-aligned scales also simplify the reading process, minimizing the risk of errors and ensuring that measurements are consistent and reliable.
One of the standout features of ProMixUSA pump calibration columns is the high-contrast blue lettering used on the graduated scales. This design choice significantly enhances readability in various lighting conditions, making it easier for operators to read measurements accurately. Whether in brightly lit environments or dimly lit areas, the high-contrast blue lettering ensures that the scales remain visible and legible. This feature is especially important in industrial settings where precise measurements are crucial for maintaining the efficiency and safety of pumping systems.
Protective Layers
In addition to their readability, the scales on ProMixUSA pump calibration columns are protected by a lamination layer. This protective layer serves multiple purposes: It prevents the scales from fading over time, shields them from physical damage, and protects against chemical attacks. In industrial environments where exposure to harsh chemicals is common, this protective layer ensures that the calibration columns remain accurate and durable. The lamination also makes the columns easier to clean, as it prevents chemicals and other contaminants from adhering to the surface of the scales.
ProMixUSA pump calibration columns are available in two primary construction materials: Borosilicate glass and PVC. Each material offers unique advantages, making the columns suitable for a wide range of applications.
Available End Cap Options
Borosilicate glass calibration columns are ideal for measuring the flow of corrosive chemicals. Borosilicate glass is known for its exceptional chemical resistance, making it a reliable choice for applications involving aggressive substances. These columns are available with end caps made of CPVC (Chlorinated polyvinyl chloride – Wikipedia), PTFE (polytetrafluoroethylene), and 316L stainless steel. Each of these materials offers additional benefits:
CPVC End Caps: CPVC is resistant to a wide range of chemicals, including acids, alkalis, and salts. It also has good mechanical strength and can withstand high temperatures. These properties make CPVC end caps a versatile and durable choice for many industrial applications.
PTFE End Caps: PTFE is renowned for its excellent chemical resistance and low friction properties. It is virtually inert to most chemicals, making it suitable for use with highly corrosive substances. PTFE end caps also have a high melting point, adding to their suitability for demanding environments.
316L Stainless Steel End Caps: 316L stainless steel offers outstanding resistance to corrosion, particularly in chloride environments. It also has excellent mechanical properties and can withstand high pressure and temperature conditions. These characteristics make 316L stainless steel end caps ideal for heavy-duty applications.
Applications
For applications involving non-corrosive or mildly corrosive chemicals, PVC calibration columns are an economical choice. Industries widely use PVC due to its good chemical resistance, mechanical strength, and affordability. PVC calibration columns provide accurate and reliable measurements without the higher cost associated with borosilicate glass columns. They are suitable for a variety of applications, including water treatment, food processing, and chemical storage.
The choice between borosilicate glass and PVC calibration columns depends on the specific requirements of the application. For instance, in environments where aggressive chemicals are present, borosilicate glass columns with appropriate end caps offer the necessary durability and chemical resistance. On the other hand, for less demanding applications where cost is a significant factor, PVC columns provide a cost-effective solution without compromising accuracy and reliability.
