I would also agree that the McKinley T34 is far better than the Graseby. We have just bought 30 to replace the Graseby pumps.
They are on central contract as well so no tender etc. required. They are providing free user training and training for us at a price.
The nurses had a preview when we had one on loan and they seemed happy with it.
It will be interesting to see how well they are received when we deploy them after the training.
