Model Parameters

Product Summary

The JSW Series centrifugal jet pump is a self-priming jet pump for clean-water supply, shallow well lifting, garden irrigation, and small transfer systems. Five models cover 0.37 kW to 1.5 kW, maximum heads from 35 m to 50 m, and maximum flow from 2.4 m³/h to 10 m³/h. The JSW Series uses a cast iron pump body, brass or 304SS impeller option, PPO venturi components, IP44 protection, and a maximum suction lift of 9 m. This self-priming water pump range provides practical selection data.

Detailed Description

A centrifugal jet pump combines a surface pump with a venturi arrangement that supports self-priming operation under suitable suction conditions. The JSW Series centrifugal jet pump is intended for clean water and liquids that are non-aggressive to its listed materials. In a shallow well or tank system, the pump may be installed above the source and connected through a sealed suction line. The JSW self-priming jet pump is useful for household supply, irrigation points, storage tanks, and transfer duties where submersible installation is not required. Actual performance depends on pipe length, elevation, fittings, source level, and the selected model.

Key Features

The JSW Series centrifugal jet pump has a cast iron pump body and support, an aluminum alloy motor housing, and a brass or 304SS impeller option. A PPO venturi pipe and diffuser are part of the self-priming hydraulic arrangement. Class B insulation, external ventilation, IP44 protection, a built-in thermal protector, and S1 continuous work are included in the listed motor data. JSW/6M, JSW/8M, and JSW/10M use 1 inch × 1 inch connections. JSW/12M and JSW/15M use 1½ inch × 1½ inch connections.

Technical Parameters

The model table is the main selection guide for the JSW Series centrifugal jet pump. JSW/6M is rated at 0.37 kW / 0.5 HP with 2.4 m³/h maximum flow and 35 m maximum head. JSW/8M and JSW/10M increase the head to 45 m and 50 m. JSW/12M and JSW/15M reach 10 m³/h maximum flow with maximum heads of 42 m and 46 m. Each listed JSW self-priming jet pump has a 9 m maximum suction lift. Liquid temperature is listed up to 60 ℃ and ambient temperature up to 40 ℃. Standard power is 220V/50Hz, with 110V/60Hz and 220V/60Hz options on request.

Engineering Advantages

A self-priming jet pump manages air in the suction line during priming, supporting use above a shallow water source when the installation is correctly sealed. The venturi pipe and diffuser work with the impeller to establish suction and deliver water through the discharge system. The brass or 304SS impeller option allows project buyers to consider material needs for the intended clean-water application. The thermal protector responds to abnormal motor temperature conditions, while external ventilation supports heat management. Correct suction piping, a suitable foot valve where needed, and proper model selection are important for stable service.

Applications

The JSW Series centrifugal jet pump can be considered for domestic water supply from tanks or shallow wells, garden and landscape irrigation, water transfer, rooftop tank filling, and small pressure-boosting systems. The JSW self-priming jet pump may also be suitable for sheltered light commercial clean-water duties when the required flow and head match the published data. It is not intended for abrasive particles, sewage, or chemically aggressive liquids. The installation should be sheltered from severe weather and follow applicable electrical and plumbing practices.

Commercial Value

For B2B buyers, the JSW Series centrifugal jet pump offers five performance options in one product family. The range covers modest household supply duties through higher-flow irrigation or transfer requirements, while retaining common clean-water positioning and related hydraulic materials. Published flow, head, power, connection size, weight, and dimension data help distributors compare models and plan stock. CGO presents the JSW self-priming jet pump range with transparent parameters so contractors and purchasers can select the appropriate centrifugal jet pump according to the actual duty point.

FAQ

Q:What liquid can the JSW Series centrifugal jet pump handle?

A:The listed application is clean water and liquids non-aggressive to the stated materials.

Q:What is the maximum suction lift?

A:Each listed model has a 9 m maximum suction lift under suitable installation conditions. How should a JSW self-priming jet pump be selected? Compare required flow, total head, suction condition, pipe losses, and power supply with the model table.

Q:Can the centrifugal jet pump be installed outdoors?

A:Use an enclosed or sheltered location and follow applicable electrical and plumbing practices.
