Repair Parts for 2" Old Design (before 9/96) Polypropylene Self-Priming Centrifugal Pump

• Precision molded construction.
• Lightweight.
• Corrosion resistant.
• Superior design.
• Low maintenance.
• More gallons per minute.
• Higher pressure

MAXIMUM ENGINE PROTECTION:

• Pump end separated from engine.
• Heavy duty slinger seal on motor shaft.
• Large weep holes between pump end and engine.
• High performance precision molded impellers.
• “V” shaped for quicker priming.

• Material:  This pump is molded from a special high strength polypropylene which is glass reinforced for strength and toughness. The rubber seals and gaskets are made of an EPDM compound with Buna and Viton seals and gaskets available at the customers request. Consult the factory for the specific chemical resistance of each compound and which is right for your specific application. New Redesigned Impeller: The impeller has been redesigned to produce more pressure and more flow than the previous design. Banjo pumps ordered with the bearing pedestal or either of the 5 HP engines available come with the new high capacity/high pressure 5 vane impeller. Banjo pumps ordered with the 3.5 HP Briggs and Stratton engine or as a pump only come with a new 3 vane impeller. Along with the new redesign, the impeller is further improved by state of the art, precision molding. Because of the exact tolerances that are achieved by the molding process, the impeller vanes are of uniform thickness, shape and weight giving the impeller perfect balance.
• Maximum Engine Protection!  We have designed the new Banjo poly pump to protect the engine seal in the event of pump seal failure. We have separated the pump from the engine by 1/2" and installed a special slinger/engine seal that completely protects the engine from any corrosive fluids. This new slinger design is the best in the poly pump industry at protecting your engine.
• For additional seal protection, small vanes are molded into the back side of the impeller. During operation, these vanes (on back side of the impeller) pump out a major portion of the liquid from the seal area which reduces pressure. The internal operating pressure of the pump is approximately 50 PSI, with the seal area operating at only 5 PSI. This leaves enough liquid in the seal area to lubricate and cool.
• Priming is now made easier by the incorporation of two new prime and drain plugs. These plugs are now made to act as thumb screws with O-ring seals for quick priming and draining before and after use. Priming is from the bottom of the pump chamber. A very small amount of liquid in the bottom of the pump is sufficient for priming since the liquid enters the volute from the bottom side. The pump will prime with the check valve open.
• The impeller has been designed for easy removal during maintenance. A 7 /16 — 14 hex nut is installed into the impeller during assembly at our plant. This nut is used to lift the impeller from the engine shaft by screwing a 7 /16 — 14 bolt into nut at the end of the impeller.
• CAUTION-WARNING:  Please do not run pump dry; restrict or reduce port sizes or dead head pump.  This could cause component failure to pump.
• DO NOT USE WITH FLAMMABLE LIQUIDS.
