We haven't used any of the Tyco pumps for over 3 years as the Nut & Diet Dept decided to go for one of these "all in" contracts. The feed, service, pumps etc all in one price to the trust. So when the contract was awarded to abbott the Tycos were retired. I have also a range of spare parts for the K224 pump if anyone wanted them. The K224 was OK - it suffered a bit with batteries dying but have a look at the new evaluation for the up to date models. Paul
