Farm and agri-processing fluids are a mixed bag that punishes the wrong pump: liquid fertilisers are corrosive, crop-protection chemicals are aggressive, and organic slurries are thick with solids. A single pump platform you can build to suit each is worth real money on a site that handles all three.
Diaphragm pumps fit because you pick the wetted material — polypropylene or PVDF against corrosive fertiliser and agrochemicals, cast iron for slurry — and they run dry safe when a tank empties and pass the solids farm fluids carry.
We supply genuine Wilden pumps for liquid fertiliser dosing, agrochemical transfer and slurry handling. Tell us the fluid and we’ll match the material and size.
