Auto prime pumps

The priming system was specifically designed with the

environment in mind. By using a positive sealing float

box and a diaphragm vacuum pump, there is absolutely

no water carry-over to contaminate the environment.

Cornell pumps are designed with the suction larger than

the discharge. This provides more flow due to reduced

friction losses. Suction lifts of 8,5 mwc and heads of up

to 250 mwc are possible depending on suction losses

and operating points on the pump curve.

Double volute design

The double volute system enables Cornell single-stage,

end-suction centrifugal pumps to easily perform big

volume and high pressure jobs. On single volute pumps,

the increasing pressure acts against the impeller area

and creates unbalanced radial forces. By contrast, the

double volute system effectively balances these forces

around the impeller to reduce shaft flexure and fatigue

for longer seal life, bearing life and shaft life.

Cycloseal

Cornell’s Cycloseal design has

proven itself in the toughest

applications from manure slurry

to starch recovery to sewer bypass

and mining applications - in

some cases more than tripling the

normally expected mechanical seal life. The Cycloseal®

system requires no external water, flush, filters, greas

cups, piping or instrumentation normally associated

with packing or double mechanical seals.Longer seal life

which translates into less pump down time and lower

maintenance costs.

External hydraulic

balance line

Cornell’s external hydraulic

balance line equalizes pressure

between the impeller hub area

and the pump suction to reduce axial loading acting on

the impeller, shaft and bearings. The balance line also

assists in moving sand and silt from the stuffing box to

the low pressure area at the pump suction, reducing

wear of the wetted parts.

Cornell Pump Company

quality and innovation since 1946

Cornell has been manufacturing pumps in Portland,

Oregon since 1946; pumps for a wide variety of agricul-

tural, municipal and industrial applications. The Cornell

pumps are known for their robust design, long life and

low cost of ownership. It is the pump of choice for those

that require trouble free performance.

Cornell built their worldwide reputation on quality and

reliability. The Cornell centrifugal pumps are engineered

and manufactured to provide continuous and trouble-

free operation. As a matter of fact, many Cornell pumps

sold in the 50’s are still providing the same continuous

and dependable service they did the day they were

installed. No one is more committed to making your

ownership a truly rewarding experience than Cornell.

60 years. Being a Dutch company, we at BBA know how

to keep our (and your) feet dry, no matter what.

For over half a century we have been supplying

pumping solutions to the industrial, agricultural,

construction and dewatering markets through-out the

world. We can provide you with anything ranging from

an off-the-shelf pumping solution to a purpose built

dewatering- or fluid management system that meets

your exact specifications.

In 2006, the cooperation between BBA and Cornell

started when the first Cornell pumps were built in BBA

Pumps canopies. The cooperation intensified through

the years and nowadays BBA Pumps represents this

global brand throughout Europe and Russia.

Pump series: HH-R-Y

Enhanced vapor handling and improved

sealing technology are central to Cornell’s

latest hot cooking oil pump innovations.

When fresh product passes through a

fryer, water tends to travel along the

bottom of the fryer in a liquid phase at

392°F (200°C), until it reaches the pump

suction where the action of the impeller breaks

up the water into smaller droplets that flash into steam.

Ordinarily, entrained steam would impair the pump’s

head and flow, but Cornell’s innovative anti-cavitation

system prevents this situation.

Hot Cycloseal®

The ‘Hot Cycloseal®’ combines the high temperature

capability of the metal bellows seal with the optimized

operating environment of the Cycloseal® system.

The ‘Hot Cycloseal®’ system prevents accumulation of

solids and vapor near the seal faces and eliminates hot

spots by maximizing cooling flow around the seal.
