The Ultimate Guide to Choosing the Right Chemical Transfer Pump

It is crucial to choose the right chemical transfer pump for industries which have to deal with efficient use of various chemicals. The right pump can make a great impact in safety and productivity especially in terms of transferring liquids to mixing solutions. Here, we will walk you through the important factors you need to consider when selecting the best pump.

Know Your Application
You need to understand your application requirements. Determine the type of chemicals your business will be handling, the required flow rate and any particular features you need for streamlined, efficient and safe operation.
 
Compatibility with chemical
This is a crucial factor too. Make sure you choose a pump which has a good compatibility with the materials used in it. Chemical resistance is essential to prevent corrosion. This consideration helps you to make informed decision where the longevity of the pump is ensured. 

Construction of pump
Choose a pump which has been constructed from materials that can withstand the chemicals. Some of the common materials used to create pump are PVC, Polypropylene, stainless steel, etc. Here, you may want to consider factors such as pressure, temperature, viscosity requirements, etc. 

Know types
Today, there are various types of chemical transfer pumps available such as centrifugal pumps, diaphragm pumps, etc. Every type has its own limitations and advantages. You need to consider factors such as pressure, flow rate, maintenance requirements when choosing the right pump type. 

Safety features
You should look for pumps equipped with advanced safety features such as overpressure protection, leak detection, grounding capabilities, etc. Check for certifications for hazardous environments.
 
Maintenance and serviceability
Choose a chemical transfer pump India which is easy to be maintained in order to ensure optimal performance and minimize downtime. Pumps with accessible components, availability of spare parts and end-to-end maintenance support by manufacturer are worth the investment. 

Costs Considerations
Cost is an important factor, but not at the cost of reliability and quality. Select a chemical transfer pump that fulfills your requirements and comes at reasonable cost. It is advisable to invest in a high-quality pump that can give you more productivity, better quality and also reduce costs related to maintenance and downtime.

Guide to Choosing an Industrial Chemical Pump | SANDPIPER

Industrial chemical pumps are designed and constructed out of materials that can withstand substances with varying levels of viscosity, corrosiveness and abrasiveness. These substances need pumps that will handle them efficiently without causing production stoppages or pump breakdowns.

Chemical manufacturers face enormous environmental, safety and cost issues.

  • Leaks during production can have severe health consequences for plant workers and surrounding environments

  • Chemicals are expensive to produce, leading to quality concerns and lost revenue if the end product is contaminated during production
  • Equipment for demanding chemical process applications can be extremely expensive with limited performance life

  • Production time is critical to maintain'this requires quality equipment that is easy to repair with dependable service available

The variety of chemicals produced or used each year in manufacturing and treatment processes across the globe is staggering. The recipes for these chemical properties stretch from simple environmentally friendly compounds to highly toxic formulations requiring a massively diverse portfolio of products to address the complex range of needs. That includes pumps used for chemical processing and transferring.

Which Type of Pump Should You Choose for Chemical Processing and Transferring?

Before selecting a chemical pump, you need to have a solid grasp of the application requirements and chemical media properties, as well as the performance and size specifications to perform the task.

Materials of Construction

The number one consideration when selecting a pump is chemical compatibility. The materials used for the construction of the pump need to be compatible with the chemical media. Because corrosion is a major concern with many chemicals, it's important to select a pump manufactured from a material that is compatible with chemical media. 

The two main categories of pump materials of construction to consider are:

Pump Sizing and Performance Specifications

Sizing a pump for the operating parameters involves matching the flow and pressure rating of a pump with the flow rate and pressure required for the process. The desired flow rate in gallons per minute (gpm) or liters per minute (lpm) is an important factor to consider when specifying a pump.

Air-operated double-diaphragm (AODD) pumps, for instance, can perform anywhere in the envelope of 0 to 280 gpm (1,060 lpm). This is achieved with a simple adjustment of the air pressure or discharge head, giving AODD pumps an advantage over other pump technologies where it may be difficult or impossible to have that much control over the flow rate. 

Desire a higher flow rate? You'll need a larger pump with larger port sizes. The higher the flow rate, the faster your job gets done.

Reasons to Choose AODD Chemical Pumps Over Other Pumping Technologies

There are many pumps on the market for chemical applications, including: centrifugal, metering, lobe, gear, screw, hose and piston/plunger. It can be difficult to find the information you need to make the right choice. 

The AODD pump, however, has proven itself as a market leader when it comes to reliability, versatility and ease of maintenance. Here are some additional benefits of AODD chemical pumps:

  • Versatility: AODD pumps typically range from ¼' (6 mm) to 3' (80 mm) porting with weights up to 245 lbs (111 kg). They can be run anywhere on their performance curve with an easy adjustment of air inlet pressure (0 to max)

  • No electricity: AODD pumps can be fully grounded for safe, reliable operation. Certified models (like ATEX or UL Listed) can be confirmed safe when properly grounded

  • Excellent chemical resistance: Many pumps are offered with wetted component materials made from stainless steel, Alloy C, cast iron, aluminum, polypropylene, PVDF and acetal. They can be fitted with FKM, PTFE, EPDM, Santoprene and nitrile materials so you can select a unit that meets your chemical needs

  • Wide viscosity range: AODD pumps can handle just about any fluid that can flow up to 90,000 cst (415,500 ssu) and can be specially fitted to achieve even more

  • Deadhead safely: Many other pumping technologies require special controls or circulation loops to allow for the pump to deadhead. AODD pumps are a great option for applications that are intermittent and require frequent deadheading. When the pressure on the fluid discharge equalizes with the air inlet pressure, the pump will stop pumping without damage

Commonly Used Chemical AODD Pump Applications

  • Processing: harsh abrasive materials like plastics, polymers, resins, glues, adhesives, pesticides, soaps, surfactants, cleaning products, acrylic acid, ammonia, sodium sulfide, paints, inks, coatings, petrochemicals, fertilizers, additives, lubricants, injection/blow molding

  • Safe transfer and mixing: aggressive, high-risk or expensive chemical transfer, tank to tote transfer, mixing/blending/extruding applications requiring containment
  • Wastewater: sumps and pits, dewatering, filter press, containment and run-off areas, water purification, water treatment, slurry
  • Aggressive environmental conditions: dirty environmental air, explosive atmospheres, corrosive environments, temperature extremes, high suction lift requirements
  • Batching: consistent delivery of uniformity across batch cycles, adaptable to a variety of batch recipes
  • Injection: low solvent coatings transfer in dosing applications
  • Disinfectants: manufacturing of sanitizers and other disinfectants, including water triethanolamine, glycerol/glycerin and propylene glycol
