Pumps designed for salt water and light chemical use, selected based on real-world performance. Chemical resistant pumps are built for liquids that would quickly damage a standard pump. This includes salt water, sea water, agricultural chemicals, detergents and light industrial fluids. These pumps use upgraded materials such as 316 stainless steel, thermoplastics and specialist seals, giving them far better resistance to corrosion than standard cast iron pumps. We supply submersible, surface and engine-driven options depending on your power supply and application.
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:
These materials don’t make a pump indestructible, but they significantly improve durability when used in the right conditions.
The deeper read: what's in this range, how to pick, and when to talk to us before you buy.
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.
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:
Surface Pumps
Installed outside the liquid and draw it through a suction hose.
Typical uses:
Engine-Driven Pumps
Used where no mains power is available.
Typical uses:
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.
To narrow it down quickly:
If your application is unusual or more demanding, it’s worth checking compatibility before purchase.
Yes. Many of the pumps in this range are designed for seawater and high-chloride environments, using 316 stainless steel and corrosion-resistant materials.
No. These pumps are intended for light chemical use only. Strong acids, solvents or highly aggressive chemicals require specialist equipment.
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.
