Pump is for water application
The CN series is a horizontal end suction water pump designed and manufactured to ANSI/ASME B73.1. It is built for water application and is used on waste and water treatment duty.
B73.1 is a dimensional standard. It fixes the centreline discharge, the foot mounting, the shaft extension and the nozzle positions for each frame size, so a CN pump of a given size occupies the same footprint as any other B73.1 pump of that size. On a replacement job that means the existing baseplate, grout, coupling spacer and pipework normally stay where they are.
Dimensions follow ANSI/ASME B73.1, so the pump matches the footprint and nozzle positions already on site.
S, M, L and XL frames cover the full duty range with a common set of bearing and shaft parts.
The full open impeller passes light solids and allows the running clearance to be reset instead of replaced.
ANSI B16.5 150LB and 300LB FF or RF flanges connect to the pipework already specified on ANSI plants.
Cast iron, ductile cast iron, carbon steel and SS304 cover clean water through to treatment plant duty.
A single mechanical seal keeps the seal chamber simple and the spare parts list short.
Transfer, recirculation and return duty inside municipal and industrial treatment works.
Raw water, filtered water and clean water transfer between process stages.
| Problem | How the CN Series Answers It |
|---|---|
| A Replacement Pump Will Not Fit the Existing Base | B73.1 dimensions mean the mounting feet, shaft height and nozzle positions match what is already grouted in. |
| Flanges Do Not Match the Pipework | ANSI B16.5 150LB and 300LB, FF or RF, are available so the mating flange does not have to be changed. |
| Spares Are Held for Too Many Frame Sizes | S, M, L and XL frames share a common design, which keeps the number of bearing and shaft items down. |
| Solids Block a Closed Impeller | The full open impeller has no shroud to bridge across, and the clearance can be adjusted as it wears. |
| Size | 1″ – 10″ |
|---|---|
| Capacity Q | max 400 m³/h |
| Design and Manufactured Standard | ANSI/ASME B73.1 |
| Flanges Standard | ANSI B16.5 150LB FF RF ANSI B16.5 300LB FF RF and so on |
| Impeller Type | Full Open type |
| Mechanical Seal Type | Single Mechanical Seal |
| Frame Type | S, M, L, XL |
| Applications | Waste and water treatment |
The standard build for clean and treated water.
Higher strength casing option where the duty pressure is higher.
Fabricated strength option for the pressure containing parts.
Austenitic stainless option for treated water and cleaner duty.
Casings and impellers are machined in house, staged through the parts store and assembled into complete sets. Finished pumps are coupled up on the test bench with the suction and discharge lines connected before they are packed.
Casings and impellers in the specified material.
Machining bays under overhead travelling cranes.
Machined parts and hardware held ready for assembly.
Rotating element, casing, coupling and motor on the baseplate.
The set is run on the test bench before packing.
The options below are the ones listed for this series. Tell us the liquid, the temperature, the duty point and the flange standard on site and we will confirm the build.
| Series | Standard or Type | Summary |
|---|---|---|
| CN Series (this product) | ANSI/ASME B73.1 | Pump is for water application |
| CI Series | ISO 2858 | Material: Cast Iron, Carbon Steel, SS304 |
| KCP Series | Horizontal Single Stage | Horizontal single-stage, back-pull-out, PP / PE / UHMW-PE |
| DE Series | DN 25 – DN 400 | Size DN 25-400 mm, Flow Q ≤ 600 m³/h |
| FA Series | BS EN733 / DIN24255 | Flow 2-1100 m³/h, Head 2-152 m, BS EN733 / DIN24255 |
| VNP Series | Vertical Single Stage | Vertical sump pump for water and waste water. Pump material is PP. |
Flow, head, liquid, temperature and supply frequency decide the size. Give the normal duty and the maximum duty if they differ.
The wetted material is chosen for the liquid, not for the pump. Check the materials listed above against what you are pumping.
See the installation, commissioning, operation and maintenance notes in the service section before the pump arrives on site.
Material: Cast Iron, Carbon Steel, SS304
Horizontal single-stage, back-pull-out, PP / PE / UHMW-PE
Size DN 25-400 mm, Flow Q ≤ 600 m³/h
The pump is designed and manufactured to ANSI/ASME B73.1.
Sizes run from 1″ up to 10″, with a capacity up to 400 m³/h.
ANSI B16.5 150LB FF or RF and ANSI B16.5 300LB FF or RF are listed, and other flange standards can be discussed.
A full open impeller.
SS304 is one of the four listed materials, along with cast iron, ductile cast iron and carbon steel.
The CN series uses a single mechanical seal.
It is the power frame that carries the bearings and shaft. Four sizes cover the full duty range of the series.
Send the duty point and the liquid and we will confirm the size, the materials and the delivery.
