Pumps & Transfer Pumps

Start with viscosity and particulates: thin clean liquids suit centrifugal pumps, viscous or particulate products need lobe, twin screw or progressive cavity designs. Then consider shear sensitivity, required pressure and whether the pump must self prime. If in doubt, describe the product and duty to the seller, who will know what the pump handled previously.

Ask when seals, rotors or the stator were last replaced, because these wear parts define condition more than age does. Turn the pump by hand to feel for roughness, inspect the product chamber for scoring, and check the motor plate matches your supply. Evidence of a recent strip down with photographs is worth paying for.

Food plants use several hygienic standards, including RJT, Tri Clamp, DIN and SMS, and they do not interchange without adaptors. Confirm the connection type and size with the seller, and remember that adaptors are cheap while a wrong pump is not. Photographs of the connections usually settle the question quickly.

Many can, but check the temperature and chemical rating of the seals and elastomers, since CIP runs hot caustic and acid through the same wetted parts. Twin screw pumps are often chosen specifically because they handle both duties at different speeds. EPDM elastomers cover most CIP regimes, while some products demand alternatives.

Most pumps palletise easily and sellers frequently arrange courier or pallet network delivery across the UK and for export. Agree packaging, insurance and any export documentation directly with the seller when you enquire. Smaller pumps often ship within days, which helps when a breakdown is holding production.
