Product Summary

CPM centrifugal pumps are compact surface pumps for clean-water supply, garden irrigation, water circulation, and light commercial transfer. The CPM centrifugal pump family covers models from CPM130 to CPM200, with power from 0.37 kW to 2.2 kW, maximum flow from 5.1 m³/h to 8.4 m³/h, and maximum head from 22 m to 55 m. Cast iron hydraulic parts, brass or 304SS impeller options, IP44 motor protection, and up to 9 m suction lift provide practical selection data for water systems.

Detailed Description

A centrifugal pump converts motor energy into water movement through a rotating impeller. The CPM centrifugal pump series is intended for clean water and liquids that are non-aggressive to the stated materials. It can be used where a surface-mounted water pump is suitable for domestic supply, tank transfer, irrigation, circulation, or pressure feed. The final operating result depends on the required flow, elevation difference, pipe length, fittings, source level, and selected CPM centrifugal pump model. Selecting the pump from the actual duty point is more useful than relying only on a maximum head or flow value.

Key Features

Each CPM centrifugal pump uses a cast iron pump body and support with an aluminum alloy motor housing. Brass or 304SS impeller options are listed for different clean-water application needs. The motor specification includes Class B insulation, external ventilation, IP44 protection, a built-in thermal protector, and S1 continuous work. CPM130, CPM146, CPM158, and CPM150 use 1 inch × 1 inch connections, while larger CPM170, CPM190, and CPM200 models use 1¼ inch × 1 inch connections. These details help installers match the centrifugal pump with the pipe system and electrical supply.

Technical Parameters

The model table provides the main CPM centrifugal pump selection data. CPM130 is rated at 0.37 kW / 0.5 HP with 5.1 m³/h maximum flow and 22 m maximum head. CPM146 and CPM158 increase the head to 26 m and 30 m. CPM170 is rated at 1.1 kW / 1.5 HP and reaches 7.2 m³/h with 41 m head. CPM190 and CPM200 provide 7.8 m³/h at 48 m and 8.4 m³/h at 55 m. All listed models have a maximum suction lift of 9 m. Liquid temperature is listed up to 60 ℃ and ambient temperature up to 40 ℃.

Engineering Advantages

A centrifugal pump should be evaluated together with its piping system because pipe friction and elevation affect the working point. The CPM centrifugal pump range provides several performance steps, helping buyers match motor power and hydraulic output to the task. The cast iron hydraulic section provides a rigid mounting base, while the impeller options allow buyers to consider the intended clean-water condition. External ventilation supports motor heat management, and the thermal protector responds to abnormal motor temperature conditions. A sealed suction line and suitable pipe diameter remain important for stable centrifugal pump service.

Applications

CPM centrifugal pumps can be considered for domestic water supply from tanks or shallow sources, garden and landscape irrigation, clean-water transfer, pressure feed, and circulation duties. They may also fit sheltered light commercial or agricultural installations when the required flow and head fall within the published data. The CPM centrifugal pump is not intended for sewage, abrasive solids, or fluids that are chemically aggressive to the listed materials. Install the pump in an enclosed or sheltered, ventilated location and follow applicable electrical and plumbing practices.

Commercial Value

For B2B buyers, the CPM centrifugal pump family provides seven performance options within one clean-water product range. This supports inventory planning across small domestic water supply needs and larger circulation or transfer requirements. Shared material choices, familiar connection sizes, and published power, flow, head, gross weight, and dimension data make model comparison more direct. CGO presents the CPM centrifugal pump range with transparent parameters so distributors and contractors can compare it with the site duty point, available power, and pipe arrangement before procurement.

FAQ

Q:What liquid is the CPM centrifugal pump for irrigation rated for? 
A:Clean water and liquids non-aggressive to cast iron, aluminum alloy, brass, or 304SS. Not suitable for sewage, abrasive solids, or chemically corrosive fluids. If your water source contains significant suspended solids or chemical additives, confirm material compatibility before selecting a model.

Q:What is the maximum suction lift? 
A:Up to 9 m under suitable installation conditions with a correctly sized suction pipe and foot valve. In practice, a shorter and straighter suction line achieves more reliable priming than one approaching the 9 m limit with multiple bends.

Q:How do I select the right model? 
A:Calculate required flow and total dynamic head. Match to the model table; select the model that covers your duty point with margin. If the duty falls between two models, select the higher-rated option to maintain stable operating conditions under variable demand.

Q:Can the pump run outdoors? 
A:Install in an enclosed, sheltered, ventilated location. IP44 covers splash protection but is not rated for continuous direct rain exposure or flooding. Follow local electrical and plumbing codes for the installation environment.
