Product Summary

CND centrifugal pumps are compact surface pumps for clean-water conveyance, domestic supply, water circulation, irrigation, and light industrial transfer. The CND centrifugal pump family includes four models from 0.37 kW to 1.1 kW, with maximum flow from 5.0 m³/h to 8.7 m³/h and maximum head from 18 m to 34 m. A cast iron pump body and support, aluminum alloy motor housing, PSU or 304SS impeller option, IP44 protection, and up to 9 m suction lift provide practical selection data for clean-water installations.

Detailed Description

A centrifugal pump moves water through the energy created by its rotating impeller. The CND centrifugal pump series is intended for clean water free of abrasive particles and liquids that are non-aggressive to the listed materials. It may be used in domestic supply, cooling circulation, heating circulation, air-conditioning loops, irrigation, and related civil or light industrial systems. The compact pump structure suits fixed installation where a surface-mounted clean-water pump is appropriate. Actual performance depends on total head, pipe length, fittings, fluid temperature, suction condition, and the selected CND centrifugal pump model.

Key Features

The CND centrifugal pump uses a cast iron pump body and support with an aluminum alloy motor housing. The listed impeller options are PSU or 304SS, allowing buyers to evaluate the material choice against the intended water condition. The motor information includes Class B insulation, external ventilation, IP44 protection, a built-in thermal protector, and S1 continuous work. Each listed CND centrifugal pump uses a 1¼ inch × 1 inch inlet and outlet connection, supporting a consistent piping arrangement across the range. These features give installers practical reference points before final system selection.

Technical Parameters

The model table is the main reference for selecting a CND centrifugal pump. CND9/25 is rated at 0.37 kW / 0.5 HP and provides 5.0 m³/h maximum flow with an 18 m maximum head. CND12/25 is rated at 0.55 kW / 0.75 HP, with 6.0 m³/h and 20 m. CND12/28 reaches 6.6 m³/h and 26 m at 0.75 kW / 1.0 HP. CND12/35 reaches 8.7 m³/h and 34 m at 1.1 kW / 1.5 HP. All models show a 9 m maximum suction lift. Liquid temperature is listed up to 60 ℃ and ambient temperature up to 40 ℃.

Engineering Advantages

A centrifugal pump is selected by matching its flow and head performance with the system resistance curve. As flow rises, the pressure available from a centrifugal pump changes, so pipe losses and elevation should be considered during selection. The CND centrifugal pump range offers several performance points for this purpose. The thermal protector responds to abnormal motor temperature conditions, while external ventilation supports heat management during operation. The 304SS impeller option may be considered where the listed material choice is suitable for the application. A sealed suction line and suitable pipe sizing remain important for stable pump service.

Applications

CND centrifugal pumps can be considered for domestic water supply, booster feed, irrigation, cooling water circulation, heating and air-conditioning circulation, and small clean-water transfer duties. The CND centrifugal pump may also serve civil, agricultural, or light industrial systems when the required flow and head fall within the published model data. It is not intended for abrasive solids, sewage, or fluids that are chemically aggressive to the listed materials. Installation should be enclosed or protected from harsh weather, with electrical and plumbing work completed according to local practice.

Commercial Value

For B2B buyers, the CND centrifugal pump series provides four performance options in a single product family. Shared connection dimensions and a common compact body size can support simpler piping planning and spare-parts comparison. The range gives distributors models for lower-flow domestic or circulation work through higher-flow transfer requirements. Published flow, head, power, gross weight, and dimensions help purchasers compare the CND centrifugal pump range with project needs. CGO presents the product family with transparent parameters so contractors can select a centrifugal pump according to the actual duty point.
