Valveless Waste Transfer Pump FAQ

Repeatability, Precision and Accuracy.

Once the pump is set, it will perform accurately over the lifetime of the pump.

As with all FMI pump the head is viscosity independent. If you can get the fluid to the inlet, the pump will be able to deliver it in a very precise manner.

Because it is a stepper motor a stepper controller will be required. We can supply a controller, or use any controller you currently have at your disposal.

Yes. Please call for options.

There are many applications but it is specifically used in many Medical and Pharmaceutical applications.

 

This pump is currently being used in a large amount of medical instruments where FDA certification has been achieved.

We recently conducted tests and found that with this product using high purity water we were able to reach 82 million cycles with no loss of accuracy.

The Repeatability, Precision and Accuracy is superior to any other similar product currently on the market.
