Values are transcribed from the supplied manufacturer catalogs. Confirm the current curve, materials, and operating limits before ordering.
Selected examples from the supplied QDL/QDLF table. The first number identifies the nominal flow family and the final number identifies the stage configuration.
| Example model | Motor power | Catalog head examples | Selection note |
|---|---|---|---|
| QDL1-50 | 0.37 kW | Approx. 20–30 m across listed flow points | Compact low-flow, higher-head water service |
| QDL1-150 | 0.75 kW | Approx. 55–89 m across listed flow points | More stages for increased head |
| QDL2-100 | 1.1 kW | Approx. 41–90 m across listed flow points | Confirm exact curve at the required duty point |
| QDL2-200 | 2.2 kW | Approx. 82–177 m across listed flow points | High-head configuration; verify pressure rating |
Range comparison
These distinctions help narrow the inquiry. They are not a substitute for an exact model curve or materials list.
| Series / arrangement | What distinguishes it | Confirm before selection |
|---|---|---|
| CDL vertical | Compact vertical multistage arrangement with supplied product photos. | Required duty point, stage count, liquid and exact wetted materials. |
| LG cast-iron vertical | Stacked cast-iron vertical stages provide higher head in a compact floor area for clean-water boosting. | Duty point, stage count, pressure rating, connections, motor and exact performance curve. |
| DG horizontal | Horizontal ring-section stages, motor and guarded coupling share a common baseplate for high-head industrial service. | Suction conditions, NPSH margin, liquid temperature, seal, mounting and exact model curve. |

Typical applications
For a model recommendation
Manufacturer and technical support
JIABO reviews required flow, total dynamic head, inlet pressure, water chemistry, materials, electrical supply and installation before confirming a vertical or horizontal multistage model. The supplied QDL/QDLF catalog provides model examples; the exact performance curve governs final selection.
Buyer questions
For final selection, confirm the exact model and operating conditions with JIABO.
It places several impellers in series to develop higher head in a compact vertical arrangement. Typical enquiries include building water pressure boosting, reverse-osmosis feed, industrial water treatment and higher-head clean-water supply.
The vertical arrangement saves floor space and is common in packaged booster and treatment systems. A horizontal ring-section arrangement offers a different baseplate, coupling and maintenance layout. Final choice depends on duty, suction conditions, space and service access.
Investigate it when the water-supply duty calls for a higher head than a suitable single-stage option, while still checking the flow, liquid and installation conditions against an exact curve.
CDL and LG are named vertical multistage series; DG is a named horizontal series. We have supplied photos for CDL but not verified current model tables for LG or DG, so ask for those datasheets before comparing ratings.
No. The actual head at your required flow comes from the specific model's performance curve and the system duty point. Share both flow and total dynamic head.
Provide required flow and total dynamic head, inlet pressure, liquid and temperature, minimum and maximum operating flow, power supply, connection standard, material preference and installation arrangement.
They are commonly investigated for higher-pressure clean-water and reverse-osmosis feed duties. The exact selection still requires the membrane-system flow, required inlet pressure, feed-water chemistry, temperature, materials and a model curve.
State the actual site supply. Common enquiries include 220–240 V single-phase or 380–415 V three-phase at 50 Hz in Europe, and 230/460 V three-phase at 60 Hz in North America. Availability must be confirmed on the exact motor nameplate.
