Energy Saving Proposal by Replacing CNWX Pumps

High Pass-through Performance

Reduces the need to remove blockages caused by foreign material, helping to cut maintenance and inspection costs.

High Pump Efficiency

Enables the use of a pump with an output one or two ranks below the existing unit (depending on specifications).

Comparison of Blockage Frequency

City B Manhole Type Pumping System

Vortex Submersible Pump
(Bore: 80 mm x 2.2 kW)

Basket is installed at inlet

Requires cleaning

Frequency of pump blockages

7 times/year

(Blockage items: underwear, towels, disposable diapers, etc.)

Replacement

Non-Clog Scroll^® Submersible Pump
(Bore: 80 mm x 2.2 kW)

Basket is removed, cleaning is not required Frequency of pump blockages: 1 time/year

Depending on the conditions, not all foreign material may pass through.

Comparison of Output Reduction

Comparison of output reduction between CNWX651 Non-Clog Scroll^® Submersible Pump and CVM65 Vortex Pump

Vertical axis: Total head (m) / Horizontal axis: Discharge rate (m³/min)

Examples

• Toyota City

  

  Our CNWX series High Efficiency and Good Passthrough Performance Submersible Pump are used in the public sewage system of the city to reduce electricity consumption and ensure stable operation.
