ABSTRACT:
Pumping apparatus which incorporates connected piston type positive displacement, slip free pumps is disclosed. They provide pumped outputs at a common displacement rate. They run out of phase to one another so that while one is pumping, the other is able to refill. A three way valve under control of a pressure responsive switch delivers pumped fluid to the down stream outlet when a pressure match is achieved. The apparatus finds application as a constant rate continuous fluid injection pump.
