What is a Penn Valley Pump (PVP)?
The Penn Valley pump is a diaphragm pump. PVP has fully acknowledged this in their patent # US 7,559,753 B2. The patent references George Burrage’s (a family member of PVP President) patent application # GB 2013287A as the basis of construction for the PVP pump. Nowhere in GB 2013287A does it reference a disc at all. This legal document fully acknowledges the fact that the Penn Valley pump is a diaphragm pump. PVP also references the use of diaphragms in all of their trademark registrations.
