Taking on the most demanding jobs, specially designed Chemical pumps have been built to withstand material others just can’t handle. Sulfates, nitrates and chlorides are no problem – as well as pretty much any other corrosive compound. They’re ideal for commercial and agricultural use.
The Chemical pump’s housing, volute and impeller are made of reinforced thermoplastic – it gives top-notch chemical resistance. The seals are made of EPDM (ethylene propylene diene monomer), which is a specialist rubber material that’s resistant to a wide range of chemicals.
The chemical pump can also handle water with solids up to 5mm in diameter – there's even a strainer to ensure nothing bigger gets through. It's capable of moving a large amount of it, too – up to 833 litres per minute.
The strainer ensures only debris 5mm and smaller passes through the machine.
What makes the Chemical pump so effective is the craftsmanship of the seals – they ensure air can't be drawn in, which causes the all-important vacuum to be lost. The impeller-to-volute clearance has also been designed in this way. It all means it not only has an impressive flow rate and pressure – but it can keep it up; it can go for up to two ours fifteen minutes before you need to add more petrol.
Also known as ‘total head’, it’s the maximum height the pump can force water from suction head to discharge head. Our Chemical pump can push it up to 32m – that’s around the length of three buses parked end to end. And the further you can pump the water, the less it’ll weigh on your mind.
As you’d expect from a Honda, our water pump engines are reliable and have low emissions – automatic decompression makes them so quick and easy to start. To keep everything in check, they also have Oil Alert™. This prevents engine damage by automatically shutting the unit down if the oil drops below a safe level.
The Chemical pump’s heavy-duty full frame offers protection to the unit as well as a handy handle for transportation. Anti-vibration engine spring mounts reduce mechanical stress on the unit, so it ticks over without juddering or making a racket.
Working constantly to make the most reliable and effective water pumps out there. They’re driven by powerful and efficient 4-stroke engines, and with mechanical seals and cast iron volutes and impellers, they’re built to last.
Honda water pumps just keep on going. That’s why Honda can offer one of the most comprehensive warranties out there, too. It maintains the same value throughout the warranty period – meaning the last day of cover is exactly the same as the first
