The CPP  has two rotors that rotate on their own shafts.  The case design mounts the rotors such that they are at an angle to each other.  As the angled rotors rotate the pistons stroke in and out of the cylinders with each piston sealed against the cylinder by a simple piston ring.  This creates the pressure and it is done eight times per revolution.  Each piston/cylinder pair has a suction and discharge valve mounted into their respective rotors creating a positive displacement pumping action that is variable by speed and scaleable to sizes great or minute.  Owning a CPP would be like having an eight cylinder reciprocating  pump with only two major parts in half the space with half the weight.  Please click back and fill out our short survey form to help bring this revolutionary technology to market.
