APV -V2 Pumps The APV model V2 Centrifugal Pump is a simplified, maintenance-friendly, and efficient centrifugal pump featuring a four- blade, fully open, non-clog impeller. Engineered for CIP cleaning, and offering a choice of five seal types, the V2 pump meets 3-A sanitary standards and is suitable for applications in the food, dairy, beverage, brewing, bakery, meat, pharmaceutical and chemical industries. For durability, the backplate is machined from heavy 316 stainless steel plate; the casing has controlled wall thickness and dimensional accuracy throughout; and a unique clamping assembly uses investment cast clamp rings with a self-locking internal angle for optimum sealing between casing and backplate. The Model V2 pump is available in eight sizes with capacities to 500 USgpm and heads to 300 feet TDH. Speciality models include pedestal mount, portable bases, and complete hopper assemblies.
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 P.S.I. with the seal area operating at only 5 P.S.I. 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.
