Product Summary

The JETDP self-priming deep well jet pump is an ejector-based surface pump for clean-water lifting from deeper well sources, domestic supply, garden irrigation, and tank distribution. The published range includes JETDP225, JETDP370, DP505A, and DP750A, from 0.55 kW to 1.5 kW. With E25 and E30 ejector options, the table lists maximum head values from 30 m to 70 m and flow values from 1.8 m³/h to 3.0 m³/h. Cast iron hydraulic parts and brass impellers provide data for deep well projects.

Detailed Description

A deep well jet pump uses a surface-mounted motor pump together with an ejector installed in the water source. The JETDP self-priming deep well jet pump is installed above ground while the ejector is placed below the water level. This arrangement supports water lifting from deeper sources when a standard shallow-well surface pump is not suitable. The JETDP range is intended for clean water and liquids non-aggressive to the listed materials. It can serve homes, garden systems, storage tanks, and small distribution networks. Water level, pipe layout, ejector selection, check valves, and pipe sealing influence delivered flow and pressure.

Key Features

The JETDP self-priming deep well jet pump has a cast iron pump body and support, an aluminum alloy motor housing, and a brass impeller. PPO venturi and diffuser components are listed in the product data. The motor has Class B insulation, external ventilation, IP44 protection, a built-in thermal protector, and S1 continuous work. E25 and E30 ejector options are shown for the range, and the connection size is listed as 1 inch × 1¼ inch × 1 inch. These details provide a starting point for pump and pipe system selection.

Technical Parameters

The table is the main selection reference for the JETDP self-priming deep well jet pump. JETDP225 is rated at 0.55 kW / 0.75 HP and lists 2.1 m³/h at 30 m or 1.8 m³/h at 40 m. JETDP370 is rated at 0.75 kW / 1.0 HP and lists values up to 40 m. DP505A is rated at 1.1 kW / 1.5 HP and lists values up to 60 m. DP750A is rated at 1.5 kW / 2.0 HP and lists values up to 70 m. Liquid temperature is listed up to 60 ℃ and ambient temperature up to 40 ℃. Voltage options include 220V/50Hz, 110V/60Hz, and 220V/60Hz on request.

Engineering Advantages

The ejector is central to a deep well jet pump system. Water recirculates through the venturi section to create low pressure at the intake and draw water from the well. Ejector selection affects the trade-off between flow and lifting head, so a JETDP self-priming deep well jet pump should be selected from model and ejector data rather than motor power alone. The cast iron hydraulic section gives a rigid mounting base, and the brass impeller is specified for clean-water duty. External ventilation assists motor heat management, while the thermal protector responds to abnormal motor temperature conditions.

Applications

Domestic and Agricultural Water Supply

The JETDP range suits clean-water supply from wells where static water level falls below the range of a standard surface pump. The surface-mounted design gives easier access for servicing compared to a submersible unit, which is relevant for installations in remote or smallholder farm settings. For buyers evaluating agricultural water system efficiency, the ejector-based deep well jet pump provides a single-phase surface solution for moderate-depth groundwater sources without the electrical complexity of three-phase submersible equipment. Built-in thermal protection and S1 continuous duty support sustained daily pumping during peak irrigation seasons.

Ejector Pump ROI Considerations

Assessing ejector pump ROI requires more than comparing purchase prices. Running energy cost across an irrigation season, lower maintenance burden for surface-mounted units, and the cost of incorrect model selection are all part of the full cost equation. The JETDP range publishes flow, head, ejector code, connection size, gross weight and package dimensions in a consistent format, giving distributors and project buyers the data to build an accurate cost model. For any cast iron jet pump supplier evaluation, the availability of complete selection data reduces the risk of specification errors at the procurement stage.

Commercial Value

For B2B buyers, the JETDP self-priming deep well jet pump family offers four motor sizes with E25 and E30 ejector choices. This helps distributors cover several deep well lift requirements within one product range. The table includes flow, head, ejector, connection, gross weight, and dimension data for procurement and installation planning. CGO presents the JETDP range with transparent parameters so contractors can evaluate it against water level, pipe layout, and delivery pressure. This supports model selection for water supply projects.

FAQ

Q:What is the difference between E25 and E30 ejectors?

A:E25 and E30 identify two ejector configurations available across the JETDP range. Each produces a different trade-off between maximum achievable head and maximum flow. The model table provides separate values for each, so select the ejector that matches your site head and flow requirements, not just the motor power class.

Q:Is the JETDP pump suitable for water with turbidity or solids?

A:No. The JETDP deep well jet pump is designed for clean water only. If the source contains suspended solids or significant turbidity, install upstream filtration before the pump suction inlet to protect the ejector assembly and brass impeller from abrasive wear.
