reASONS NOT TO BUY DEMOUNTABLE PUMPS!

In order to detach a motor from the ink pump end you require a pump end design with supporting bearings at both ends of the pump. These bearings support the drive shaft in place so the motor can be re-attached in complete alignment. Our many years of experience in ink pumps inform us that any bearing running in solvent or water based ink will not last long. That requires regular pump maintenance to replace bearings at a high cost. For this reason Powerwise manufactures pumps with NO bearings. The drive shaft is attached and aligned from the motor. For customers it may mean a new approach to their cleaning regime and care must be taken to not damage the motors with cleaning fluids or immersion. Our firm belief is this in turn will elongate the life of the pumps and greatly reduce maintenance costs.

To provide power to the pump end on a demountable pump end the motor must have a coupling fitted between the motor shaft and the pump shaft. Most manufacturers use a plastic coupling which has teeth and must be perfectly aligned to fit together. Experience shows us that many customer have difficulty aligning those couplings and this results in damaged teeth. This requires regular replacement of the couplings adding up to more down time and expense.

This recent review is from a new customer switching from demountable motors to the Powerwise style pump.

"The two Powerwise pumps have performed well and I intend to buy more when the site manager allows the purchase. Last year we bought the Graymill’s m3 pump to standardize across our facility. They have been hit and miss with our press crews. The motor detaches from the pump for cleaning but is connected with plastic gears. The gears are delicate and need to be adjusted correctly to “mesh” properly causing problems in our production environment.

My plan was to order a few of your pumps each month to put on my east presses. Your pump is more durable than the two piece m3 and the press crews are requesting we get them back. The problem is we bought over 40 pumps last year and are stuck with them for now.  

I will buy some when I can. We have 6 presses with 8 printing units each and will need some pumps in the future. 

Thank you"
