Product Summary

The CND centrifugal pump from CGO is a single-phase clean water pump built around a cast iron body with a PSU or 304 stainless steel impeller. Designed for continuous S1 duty, this industrial centrifugal pump handles liquid temperatures up to 60°C and delivers up to 8.7 m³/h flow at 34 m head. Four CND models cover 0.37 to 1.1 kW, and the HTM32-160A extends capacity to 2.2 kW for higher-flow installations. With IP44 protection, a built-in thermal overload, and Class B insulation, the CND centrifugal pump is a dependable cast iron water pump suited for water supply, HVAC circulation, and irrigation.

Detailed Description

What makes the CND centrifugal pump a sensible buy for B2B projects is the combination of robust materials and a practical, no-fuss design. The cast iron pump body and cast iron support structure form a solid base that resists deformation under sustained operating pressures—even when ambient temperatures push close to the 40°C ceiling. Pair that with an optional 304 stainless steel centrifugal pump impeller and you get a clean water pump that can be tailored to specific water chemistry without switching to a different product line.

On the motor side, Class B insulation combined with external ventilation cooling keeps winding temperatures in check during the long, uninterrupted runs that building services and HVAC systems demand. The IP44 rating on this industrial centrifugal pump handles water splash from all directions, making it suitable for semi-exposed plant rooms or covered installations. A built-in thermal protector cuts power automatically if temperatures reach unsafe levels—no external relay logic or additional components required. The motor shaft is carbon steel as standard, with 304SS welding available on request for installations where contact with treated water is a concern.

Key Product Features

The CND centrifugal pump brings together a feature set that experienced B2B buyers will recognize as genuinely useful rather than just a spec-sheet listing. Cast iron body and pump support give this cast iron water pump a vibration-resistant, dimensionally stable structure for fixed mounting. PSU and 304SS impeller options allow project engineers to match material selection to water quality requirements without custom fabrication lead times. All four CND centrifugal pump models share identical 1¼" × 1" port sizing and a 405 × 240 × 235 mm footprint—a practical advantage when piping the same layout across multiple clean water pump units on a single project. IP44, Class B insulation, and S1 continuous duty together cover a wide range of industrial centrifugal pump applications in commercial and light industrial settings. Multi-voltage support—220V/50Hz standard, 110V/60Hz and 220V/60Hz on request—keeps international procurement straightforward.

Engineering Advantages

CGO designed the CND centrifugal pump series with a deliberate performance staircase across four models. The CND9/25 delivers 5.0 m³/h at 18 m head; the CND12/35 reaches 8.7 m³/h at 34 m head. That spread lets system engineers select a pump that runs at or near its peak efficiency point, rather than over-specifying and running a larger cast iron water pump at part load. This matters in practice: a correctly sized industrial centrifugal pump uses less energy and places lower stress on bearings and seals throughout its service life.

The stainless steel centrifugal pump impeller option reflects the same thinking. PSU is an excellent choice for standard clean water pump service—lightweight, chemically stable, and cost-effective. The 304SS upgrade is there for installations where mildly treated water or low-concentration chemical additives circulate in the same loop. CGO validates every CND centrifugal pump unit through factory acceptance testing before shipment, confirming that measured head, flow, and power consumption align with the published performance data.

Primary Applications

The CND centrifugal pump covers more ground than its compact size implies. Domestic and light-commercial pressure boosting is the most common application—the clean water pump runs quietly, requires minimal routine maintenance, and handles the variable demand cycles typical of residential and small-office supply. HVAC engineers rely on it as a reliable industrial centrifugal pump for chilled water and hot-water heating circuits, where the 60°C liquid temperature limit comfortably covers secondary loop service. Irrigation projects—both agricultural field systems and landscape watering—benefit from the cast iron water pump's multi-voltage flexibility and 9 m suction lift capability. Light industrial loops such as cooling water recirculation, machine-room cold-water top-up, and similar clean water pump circuits also fall within the rated operating envelope of the CND centrifugal pump.

Commercial Value

For wholesale distributors and project contractors, the CND centrifugal pump presents a clear proposition: a factory-tested cast iron water pump product line at direct-factory pricing, backed by consistent production quality. The four CND models share footprint dimensions and port sizes, so distributors can hold fewer SKUs while offering coverage across a meaningful performance range. CGO supports OEM buyers requiring custom voltage specifications or stainless steel centrifugal pump impeller upgrades. Large industrial centrifugal pump orders benefit from CGO's established supply chain, stable production capacity, and standardized export documentation. The HTM32-160A extends the same product philosophy—cast iron construction, thermal protection, multi-voltage flexibility—into the higher-flow segment, giving buyers a single trusted source for the full clean water pump range.

FAQ

Q: What is the suction lift rating for the CND centrifugal pump?
All four CND clean water pump models are rated for up to 9 m total suction lift. The HTM32-160A is rated at 7 m.

Q: Can I order the CND centrifugal pump with a 304SS impeller?
Yes. CGO offers this industrial centrifugal pump with a 304 stainless steel impeller and 304SS-welded motor shaft on request.

Q: Is this cast iron water pump suitable for outdoor installation?
The IP44 rating covers water splash from all directions, but CGO recommends a covered enclosure or weatherproof housing for sustained outdoor exposure.

Q: What voltage options are available for the CND centrifugal pump?
The standard specification is 220V/50Hz. 110V/60Hz and 220V/60Hz variants are available on request to support international project requirements.
