Pump Design Features
P3 Series Piston Pump features include:
• All the same advantages of the P2 Series, namely a reliable, compact package with very low noise levels.
• Because of the unique built in impeller, P3 offers significantly higher self priming speeds than competitive designs and the
capability to operate the pump successfully at high elevations, without the need for pressurized reservoirs.
• Unique port layout with both operating ports on the same side of the pump, resulting in more accessible plumbing.
• Built in air bleed valve for automatic priming of the pump at start up.
