FEATURES

Discharge – Heavy-duty cast iron

construction provides smooth
water passage to column pipe. NPT
threads standard.

Bowl and Intake Bearings –

Fluted, cutless rubber type assures
superior abrasive-handling charac­teristics, located at each stage.

Glass-reinforced polycarbonate
resists abrasives and provides
smooth water passages for
minimum friction loss. Ensures
optimum pump efficiency.

Pump Bowls – Highly efficient
hydraulic design… threaded bowl
design in gray cast iron.

Upthrust Bearing – Bronze
upthrust bearing provides positive
momentary upthrust protection
during start-up.

Intake Bracket – Efficient hydraulic
design minimizes entrance
losses, ensuring maximum pump
performance.

Stainless Steel Pump Shaft –

Precision straightened shaft is corro­sion-resistant stainless steel.

Pump/Motor Coupling – Stainless
steel for maximum corrosion
resistance… precision machined
to ensure accurate alignment and
power transfer.

Intake Screen – Stainless steel
material offers maximum corrosion

OUTLINE DIMENSIONS PUMP PERFORMANCE – 70 GPM

Dimensions (in inches) are for estimating purposes only.

Tested and rated in accordance with Water Systems Council Standards.
NOTE: Pumps installed with a PRO-Source™ tank require a 100 PSI relief valve. Pumps installed with a conventional tank require

a 75 PSI relief valve. Relief valve must be capable of relieving entire flow of pump at relief pressure.

For lengths,
