What Makes a Pump “Chemical Resistant”?

What Makes a Pump “Chemical Resistant”?

The difference comes down to materials.

Standard pumps typically use cast iron and basic seals, which can corrode quickly. Chemical resistant pumps are built using:

  • 316 stainless steel for improved resistance to salt and chlorides
  • Thermoplastic or composite bodies that won’t rust or degrade
  • Viton or EPDM seals selected for chemical compatibility
  • Silicon carbide mechanical seals for longer life in harsh liquids

These materials don’t make a pump indestructible, but they significantly improve durability when used in the right conditions.

Buying guide

More about this category.

The deeper read: what's in this range, how to pick, and when to talk to us before you buy.

Important: the limits of our chemical advice

These pumps are designed for light chemicals and salt water. They are not suitable for highly corrosive chemicals such as concentrated acids, strong alkalis, solvents or oxidisers.

Pumps are not tested against every chemical or every concentration. We cannot offer bespoke chemical compatibility advice for your specific liquid. The responsibility for confirming compatibility sits with the buyer or their engineer, using the manufacturer chemical resistance data and the pump's published wetted-parts specification. If in doubt, do not pump it.

Submersible, Surface or Engine-Driven?

Choosing the right type depends on how and where the pump will be used:

Submersible Pumps

Designed to sit directly in the liquid. Ideal for tanks, sumps, bilges and flooded areas.

Typical uses:

  • Tanks, sumps and chambers
  • Boats, bilges and marine use
  • Industrial and agricultural settings

Surface Pumps

Installed outside the liquid and draw it through a suction hose.

Typical uses:

  • Transferring liquids between tanks, IBCs or containers
  • Irrigation and washdown
  • Situations where the pump needs to remain accessible

Engine-Driven Pumps

Used where no mains power is available.

Typical uses:

  • Remote locations and agriculture
  • Coastal or marine environments
  • Emergency response and high-flow transfer

Typically constructed from corrosion-resistant materials such as glass-reinforced components and stainless steel fasteners, making them suitable for salt water and light chemical use. Must be operated outdoors.

Choosing the Right Pump

To narrow it down quickly:

  • What are you pumping? (salt water, detergent, light chemical)
  • Is power available? (electric or engine-driven)
  • Where will it sit? (in the liquid or beside it)
  • What flow do you need? (litres per minute at your required head)

If your application is unusual or more demanding, it’s worth checking compatibility before purchase.

Common questions

Frequently asked questions.

Can these pumps be used for seawater?

Yes. Many of the pumps in this range are designed for seawater and high-chloride environments, using 316 stainless steel and corrosion-resistant materials.

Can I use these pumps for strong chemicals or acids?

No. These pumps are intended for light chemical use only. Strong acids, solvents or highly aggressive chemicals require specialist equipment.

Do I need to check compatibility before buying?

For standard uses like salt water or detergents, the range is suitable. If you are pumping a specific chemical or higher concentration, it is good practice to check compatibility with the pump materials before use.
