SELF-PRIMING PUMPSCORNELL
EFFICIENT, DURABLE, INNOVATIVE and dependable are all words that people use to describe Cornell pumps. The Cornell STX, STL & STH Self-Priming Lines are the newest products 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 Self-Priming Line exceeds the efficiency ratings of the competition by multiple efficiency points, without sacrificing lift capability. 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 Self-Priming Pumps follow 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 assemblies to retrofit into your existing pump volute.
SELF PRIMING PUMPFEATURES AND BENEFITS CORNELL CYCLOSEAL® SEALING SYSTEM with Run-Dry™, Type 2 silicon carbide seal and grit removal system.
CORNELL PUMP FIVE-YEAR WARRANTY is standard on all STX STL, & STH pumps.
17-4 PH STAINLESS STEEL SHAFT and oversized bearings extends the operating range and reduces shaft breakage.
HIGH-EFFICIENCY DESIGN pumps more liquid using less energy for substantial savings over the life of the pump.
ADJUSTABLE WEAR PLATE is abrasion resistant and easily accessible for replacement.
MODULAR DESIGN rotating assembly for easy conversion to SAE engine driven applications. The unique case design immediately identifies it as a Cornell pump.
DOUBLE-LIP SEALS with atmospheric vents provide added protection for bearings.
DUCTILE IRON CONSTRUCTION for increased durability and resistance to wear.
HIGH RPM CAPACITY for high-head and engine driven applications.
DROP-IN REPLACEMENT for many existing installations.
OVERSIZED OIL RESERVOIR provides superior bearing cooling.
THREADED IMPELLER for increased strength.
SELF-PRIMING PUMPS CORNELL
REMOVABLE COVER PLATECornell STX, STL & STH Pumps have a removable coverplate that provides quick access to the pump’s impeller.
INNOVATIVE FEATURES
SOLIDS HANDLING IMPELLERDuctile iron two-blade impeller handles solids up to 3” in diameter. Impeller backvanes reduce the buildup of foreign matter and pressure in the stuffing box.
THE INNOVATIIVE CORNELL CYCLOSEAL® SEALING SYSTEM Eliminates air and gas pockets and keeps solids away from the seal area, extending seal life up to 3 times the industry average.

STH series is high head WITHOUT requiring a booster pump. With heads up to 253’, excellent efficiencies and flow, the STH series is able to tackle the most demanding applications. No booster pump means reduced maintenance and a simpler, more reliable solution.
WE PUT OUR BEST IDEAS TO THE TESTOur modern hydraulics lab is the proving ground for all Cornell pumps. Our goal is to deliver the most efficient pumps at a time when energy costs are escalating. Technicians, under the direction of Registered Professional Engineers, conduct certified performance tests that precisely determine the performance and NPSH required for particular design conditions.
The focal point of the research facility is a 80,000 gallon (302,833 liters) closed loop system for running accurate low pressure tests. It can circulate up to 60,000 gallons (227,125 liters) of water per minute. All test motors are calibrated, and adhere to the Hydraulic Institute Standards in testing. A variable frequency drive will allow us to test pumps up to 4,000 horsepower at various speeds. Additional tests can be conducted upon customer request.

CYCLOSEAL® DESIGNThe 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.
EXTENDED SEAL LIFE: Cornell’s Cycloseal® design has proven itself in the toughest applications — in some cases more than tripling the normally expected mechanical seal life.
SYSTEM SAVINGS: The Cycloseal® system requires no external water flush, filters, grease cups, piping or instrumentation normally associated with packing or double mechanical seals.
MAINTENANCE SAVINGS: Longer seal life which translates into less pump down time and lower maintenance costs.

SELF-ALIGNING SEALS compensate for shaft movement, primary sealing wear, and machine tolerances.
NON-PUSHER DESIGN has no dynamic O-rings to hang up. All seal movement occurs in the bellows.
NON-CLOGGING SINGLE COIL SPRING is more dependable than multiple spring designs.
NO SET SCREWS to mar the shaft or sleeve.
TEMPERATURE LIMITS -40°F/-40°C to +160°F/70°C (Buna); -40°F/-40°C to +400°F/200°C (Viton®).*

EFFICIENT BY DESIGN
Immersible motors are designed to be used in dry-pit applications where there is a possibility of flooding. Why take a submersible motor that was designed to run submerged 100% 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 100% 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 30 feet of submergence depth for a two-week 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 30 minutes at a submergence level of 3 ‘. Hardly enough time to deal with any kind of flooding emergency!
