6 Points to Choosing the Right Pump

There are three categories that the main types of pumps – drum pump, pail pump and bottle pump – are in. These categories include manual, safety and power pumps. There are several points to keep in mind when choosing a pump.

First, you need to know the types of chemicals to pump as well as the thickness of the liquid. You need to know the sizes of the containers that will be used along with the compatibility of all chemicals in the liquids being pumped. Know how much is going to be dispensed per minute or per stroke and whether you need food grade pump or not. In addition, the following six points will help you choose the right pump:

1) Chemical Compatibility

Be sure that the parts of the container that make direct contact with the liquid are chemically compatible with your product. Go over the Material Data Safety Sheet carefully. The MSDS accompanies your product when you buy it. It breaks down all the names of the chemicals that comprise the product you intend to pump. You should also be aware of the thickness of the liquid or its viscosity and thickness.

2) Dispensing Requirements

Figure how much liquid you will need to dispense per minute or stroke. How fast will you need it pumped? Hand pumps can pump a preset amount per stroke. When it comes to per minute pumps though, these pumps depend on the strength of the user.

3) Rate of Gallons Per Minute

Power pumps have a specific rate of gallons per minute that they can pump. The rate can change with the viscosity of the fluid that is being pumped along with the pump power. The product will have an up-to rate that delivers a specific GPM or gallons-per-minute figure. This gives you a guideline from which to work as well as an idea of the best-case scenario.

4) Food Grade Pump Considerations

There are certain restrictions involved in working with food or regulated substances. Pumps that work for these applications include manual and power pumps.

5) Container Sizes

Consider these by figuring out if you will only pump once from the container or if you will pump the same liquid constantly. If you will be transferring one container to another, this will also impact the size you choose.

If you will be using different sized containers, find a pump that adapts to them all. The tube of the pump will help you determine the container size that is best for your application. As a rule, you could use a 55-gallon pump in a 15, 20 or 30-gallon drum. As long as you do not mind that the top of the pump will be positioned above the smaller containers, this is a convenient arrangement to set up for your pump requirements.

6) Power Pumps versus Manual Pumps

These two choices require careful thought as manual pumps are powered by a user and require more endurance to operate. Power pumps can operate using air or electricity. The choice you make depends on the type of power currently in your facility or the type of power you plan to install.

If the drum will hold hazardous chemicals it must meet UN/DOT requirements under 49 CFR 173.3 (c). In addition, you can choose from an array of sizes, linings, colours and types of available pumps.

With the points illustrated above, your decision-making process should prove to be easier and more efficient.
