Pumpflow Ltd operate with a high level of vertical integration with design, fabrication, machining, assembly, testing and site installation work all carried out by our team of highly skilled and experienced engineers.
One process that we do outsource is casting of specialist alloys. The impellers for our “Fish Safe” pumps are produced in Nickel Aluminium Bronze material.
These alloys are for applications such as: Pump impellers and ships propellers, owing to their excellent corrosion, wear, and galling resistance resultant of the alloys complex copper-aluminium adherent oxide surface film, which acts as a protective barrier and is self-repairing, even down to very low levels of oxygen in the harsh service environments.
These alloys are tricky to cast, hence Pumpflow Ltd source such castings only from trusted supply chain partners based in the United Kingdom.
The pump manufacturers relationship with a foundry is a critical one. From liaising on component shape and castability and exchanging 3D drawings for pattern making and foundry methoding.
We hope you enjoy this short video of a “Fish Safe” pump impeller being moulded and cast in Sheffield, England.
