One size doesn’t fit all: The dangers of using the wrong pump type
We often see businesses using whatever pump they have on hand or what was recommended years ago, but the truth is that pumps just aren’t universal tools.
What may work in one setup can cost you long term in another.
1. Mismatched Pumps = Wasted time and Money
That “bargain” pump you fitted last year? If it’s the wrong design for your liquid, it could be damaging your system and your profits every time it runs.
Using the wrong type of pump can lead to:
- Premature wear
- Frequent Breakdowns
- Poor or erratic flow
- Inconsistent pressure
- Overheating
- Cavitation
- Excessive power draw
- Higher cost of ownership long-term
2. Liquids vary. Same with pumps.
Different types of liquids affect pumps in different ways.
Amongst other factors… the pump needs to match the viscosity, temperature and chemical properties of the liquid you’re moving.
For example:
- Thick or Abrasive liquids – can destroy a standard Centrifugal pump designed for thinner liquids like water.
- Delicate or Shear-sensitive liquids – need gentle handling, not high speed impellers.
- Corrosive additives or Chemicals – Need compatible materials and sealing options or you’ll be buying a new pump every month.
3. Common mistakes we see
These issues don’t just cost money, they cause delays, frustration and production bottlenecks.
- Using pumps with tight clearances or complicated sealing arrangements for Abrasive liquids.
- Using pumps with a high speed for Thick or Viscous liquids.
- Pumping non-lubricating liquids like solvents with pumps designed for lubricating liquids like oil.
- Using designs that can get clogged or blocked easily for liquids with solids and particulates in them.
- Cutting corners on materials only to end up with your dangerous chemicals on your factory floor.
- Companies buy pumps on auction without understanding their designs or why they may not be suitable for their unique applications.
Did you know?
In many cases when working with viscous liquids like oil for example, it is important to slow the pumps down.
If a pump runs too fast for the viscosity there is not enough time for the liquid to fill the cavities inside the rotating parts of the pump and it will just slip.
4. Using the right pump makes life easier
It all comes down to matching the right tool to the job. When your pump matches your system and liquid:
- You get consistent, measurable performance.
- Maintenance intervals are longer.
- Energy use drops
- The quality of your product ends up better at the end.
- You get to focus on things that matter, like getting your orders out – not the workbench.
