Twin-screw, gear and centrifugal pump spares: mechanical seals, wear kits, timing gears, bearings and shafts.
Send the serial number of the unit, and a photograph of its nameplate with it. The serial number is what the part is ordered against; the nameplate settles which version of the machine it belongs to, because the same number can appear on more than one.
Part numbers are welcome where you have them. The quotation states the genuine part, its origin and its lead time.
The hygienic twin-screw pump used on many dairy lines runs with no metal-to-metal contact between the screws, handles approximately 177 °C and a differential pressure to 362 psi, and pumps the CIP solution that cleans it. Its generation has been superseded.
Supersession follows a sequence: parts remain available, then lead times lengthen, then supply moves to order-only with a minimum quantity, then support ends. The position of a specific installation is established by asking the manufacturer and recording the answer.

The screws intermesh without contact and the product is moved rather than sheared. The seal face is the only sliding contact in the machine, and the only component here with no published interval.
