E5 1/2" Pump: Bolted Metallic

Versa-Matic® provides maximum performance in a mini package with our E8 3/8" pumps. Small enough to fit in your hand, yet capable of pumping up to 6.8 gallons per minute, these pumps can be mounted upright, sideways, and even inverted to adapt to your application. They also feature our patented Elima-Matic® Air Valve System to deliver non-stalling, non-icing, lube-free operation as well as the elimination of blow-by.
