The VMP has been recently awarded a US Patent for the method of dynamic dispense adjustment.

The VMP uses a rotating reciprocating positive displacement pump to provide an accurate repeatable shot. Two stepper motors driven by an onboard microprocessor control this system. One motor drives the pump, the other adjusts the stroke length of the pump. This allows for ultra fine adjustments to be made to the shot size. Fine tune your shot for your needs. No guessing and no tools. No air is needed. The system can be freestanding or can be integrated into an existing system. Up to 100 unique programs can be stored in the pump's memory.
