Cascade Pump Company — manufacturers of axial & mixed flow pumping equipment

Cascade Pump Selection

Great hydraulic selections from 6" to 72" pipe, 1,500 GPM to 130,000 GPM, at 3 feet to 110 feet of head.

Municipal water & wastewater

Pump selection for municipal water systems

Cascade vertical turbine and mixed flow pumps serve water treatment plants, high-service pump stations, raw water intakes and distribution booster stations across North America. Every model in the selector is available with NSF/ANSI/CAN 61 and 372 certification for potable water service, and selections comply with applicable AWWA E103 standards.

Built for utility specifications

Municipal specifications routinely call out ANSI/HI 9.1–9.5 for rotodynamic pump design and AWWA E103 for horizontal and vertical line-shaft pumps. Cascade selections are prepared against those guidelines, and the data sheet you download states them explicitly — ready to drop into a specification or submittal package.

Intake design and submergence, calculated for you

Every selection includes a Hydraulic Institute 9.8 minimum submergence calculation for continuous operation, plus a pump-down / intermediate level for infrequent operation. The NPSHr comparison includes atmospheric credit at sea level, so the number you see is the water depth you actually need over the bell — the value civil and structural engineers need for wet well design.

From duty point to rep in one step

Enter flow and bowl head, review the ranked selections with full curves (head, efficiency, brake horsepower, NPSHr), then send the selection directly to the Cascade representative for your ZIP code — the request reaches the right rep and the factory with the data sheet attached.

How the selector works

  1. Enter your design flow and bowl head (plus specific gravity and speed if known).
  2. Get ranked Cascade selections with impeller trim, stages, efficiency, brake horsepower and NPSHr at your duty point.
  3. Download the full data sheet (PDF or Excel) with curves, or send the selection straight to your local Cascade representative.

Selections follow ANSI/HI 9.1–9.5 guidelines for VS1 and VS2 pumps, and Hydraulic Institute 9.8 intake guidance is calculated for every result. All results are preliminary selections; final quotes and submittals come from Cascade staff.
