CORNELL SELF-PRIMING PUMPS STX & STL SERIES INDUSTRY LEADING EFFICIENCY WITH CYCLOSEAL SYSTEM FIVE-YEAR WARRANTY
SELF-PRIMING PUMPS CORNELL Efficient, durable, innovative and dependable are all words that people use to describe Cornell pumps. The Cornell STX Self-Priming Line is the newest product from Cornell Pump following a tradition of building world-class pumping equipment. Efficient by Design is not only our mantra, but it is also our priority when designing our equipment. The STX line exceeds the efficiency ratings of the competition by multiple efficiency points. This improvement translates into energy cost savings over the life of the pump. In addition to being focused on efficiency, Cornell Pump is also known for its innovative features. The STX follows this tradition by the addition of the Cycloseal sealing system, which will extend your seal life. Have an existing self-primer installed? Contact Cornell Pump regarding the retrofit program, which allows the Cornell STX rotating assembly to retrofit into your existing pump volute.

SELF-PRIMING PUMPS CORNELL INNOVATIVE FEATURES CYCLOSEAL DESIGN The patented, premium mechanical seal system that distinguishes our pumps from all others. One of the main reasons STX pumps have a distinctive edge on competitors is Cornell s patented Cycloseal design that removes solids and abrasive material from the seal area, while purging air and gas pockets. This innovative cyclonic action extends seal life and eliminates the need for venting or flush water. These benefits come about from the Cycloseal s unique deflector vanes. TYPE II SEALS Cycloseal utilizes Type II seals as part of the Cycloseal system. SELF-ALIGNING: Automatic adjustment compensates for abnormal shaft movement, primary sealing wear, and machinery tolerances. NON-CLOGGING SINGLE COIL SPRING: Greater dependability than multiple spring designs. NON-PUSHER DESIGN: No dynamic O-rings to hang up. All seal movement occurs in the bellows. NO SET SCREWS: Nothing to mar the shaft or sleeve. TEMPERATURE LIMITS: - F to +1 F (Buna); - F to + F (Viton ). SEAL FACES: Tungsten carbide vs. silicon carbide. ELASTOMERIC BELLOWS: Buna-N, Viton. HARDWARE: Stainless steel. CYCLOSEAL BENEFITS EXTENDED SEAL LIFE: Cornell s Cycloseal design has proven itself in the toughest applications from manure slurry to starch recovery to clear water, food processing, self-priming and hot cooking oil applications in some cases more than tripling the expected mechanical seal life. MAINTENANCE SAVINGS: Longer seal life translates into less pump down time and lower maintenance costs. BACK PULL-OUT DESIGN The rotating assembly can be removed without dismantling the pump or disturbing the piping. DUAL PROTECTION OF BEARINGS Atmospheric barrier and double lip seals provide bearing protection in the event of seal failure. HEAVY-DUTY BEARINGS HEAVY-DUTY THRUST BEARINGS WITH SEPARATE OIL RESERVE sized for V-belt drive loads. Separate oil filling plugs for bearings and mechanical seals with sight gauges. ROTATING ASSEMBLY Cornell s rotating assembly allows for retrofits of existing installations to upgrade your existing pump with Cornell Pump quality and features.

Why take a submersible motor that was designed to run submerged 1% of the time and modify it to run in air 99% (or most of the time) and submerged 1% of the time (in case of a flood)? This seems backwards. The correct approach is to take a TEFC motor that is designed to run in air 1% of the time and adapt it to run submerged 1% of the time (in case of a flood). ImmersIble motor basic design: The basic design of the immersible pump/motor incorporates a premium efficient, inverter duty, P-Base or C-Face TEBC motor (totally enclosed, blower cooled). The motor, as the name implies, is totally enclosed and cooled by a blower on top of the motor. If the motor becomes submerged, the blower motor fan shuts down without affecting the main motor. While the motor is temporarily submerged, the media cools the motor just like a true submersible. A special conduit box is used to prevent water leakage into the motor. The motor is designed to prevent infiltration of water along the shaft and into the motor by utilizing a triple redundant sealing system, including a patented hydroseal design. The motor-end bell housing incorporates the inverted cup principle, which traps an air bubble under the motor as water rises, thus keeping water away from the shaft seal. The shaft is fitted with a hydroseal, which expells water and further reduces the chance of water reaching the shaft seals. The Immersible motor can withstand up to 3 feet of submergence depth for a twoweek period. This exceeds the requirements of Immersible motors that is described in the industry standard Index of Protection IP67. Competitive designs only allow immersion of the motor for a period of time not exceeding 3 minutes at a submergence level of 3.
