Dura-Seal OUTPERFORMS: Superior Flow Volume: Unique progressive helical steel gear design for more surface area and flow. Precise manufacturing for tighter tolerances and maximum efficiency. Internal pump housing geometry for smooth flow. Enhanced Leak Resistance: Superior sealing components (high performance elastomeric and Viton seals). Mechanically balanced seal and bearing design reduces pressure and wear on the seals. No packing seal/nut which could be a point of potential leakage. Dura-Seal OUTLASTS: Longer, More Reliable Pump Life: Superior seal and bearing components. Progressive floating gear design for less friction and wear. Simple and balanced design. Shorter, larger diameter nitrided shafts to handle higher stress loads. Superior manufacturing/machining. Easy Do-It-Yourself Repair and Maintenance: Rapid access bolt-on end caps. Simple, straightforward combination seal and bearing design. Lower Total Cost of Ownership: Mid-range purchase price. Low operating, maintenance and repair costs. Less money lost due to downtime.
DURA-SEAL THE INSIDE STORY. High Performance Elastomeric Double Lip Seals (5) Rapid-Access Bolt-On End Caps (4) Viton Lip Seals (5) High-load Capacity s (5) Aluminum Bronze Bushings (3) Larger Diameter (1¼) and Shorter Nitrided Shafts THE IMPORTANCE OF BALANCE In order to achieve the highest standards of performance, lifespan and safety, pumps should be designed with symmetrically balanced gears, shafts and bearings or bushings. Particularly in pumps with helical gears where loads are quickly re-distributed when the pump rotation is changed. Utilizing the latest in functional and stress Floating Progressive Helical Steel or Rubber Gears analysis testing, Bowie engineers have re-defined combo-style pumps by devising a very simple and exceptionally symmetrically balanced bushing and bearing design pump. With fewer components! The result: Longer pump life. Enhanced leak resistance. Fewer potential problems. Easier and less expensive repairs. WHAT WE MEAN BY THE PERFECT BALANCE Symmetrical balance is best illustrated in pump designs with the same elements on each end of the shaft along with the same shaft dimensions on each side of the gear. This maximizes pump life and performance. For example, would you drive a truck built with an axle that was not equally supported on both sides? Just imagine the wear and tear that would result. Like a truck axle, Dura-Seal pump shafts are designed to evenly distribute the load and stress. By symmetrically balancing bushings and bearings across the pump, the Dura-Seal performs more efficiently and lasts longer. Gear (Load) Idler Shaft Bushing Bushing

DURA-SEAL IS NOT THE FIRST COMBO-STYLE PUMP. IT S SIMPLY THE BEST. Using Bowie s advanced components and engineering expertise, we have developed an ingeniously simple seal and bearing design resulting in the most mechanically balanced, toughest, high output combostyle pump on the market.
WHAT YOU NEED TO KNOW ABOUT GEARS: Dura-Seal Series pumps are available in two gear configurations: 1. Progressive Helical Steel Gears: The unique twist angle of the helix and the innovative parabolic tooth profile, only attainable with a five-axis machining centre, make Bowie s progressive helical steel gears the top choice when you require longer pump life and maximum flow volumes. These gears are recommended: Wherever rubber is not compatible or tends to break down prematurely (eg. concentrated acids, halogenated solvents/hydrocarbons). High temperature, high pressure operating conditions. High volume output at higher RPMs. 2. Buna-N Synthetic Rubber Gears: Our proprietary Buna-N rubber gears are the longest lasting high strength rubber gears on the market. They are everything you need for most standard applications.
