ACTUAL PRODUCT PHOTOY80QJD
Y80QJD + Y90QJD · OIL-FILLED
Deep-well water supply, matched to the bore and duty point.
QJD pumps pair a slim multistage hydraulic section with an oil-filled motor. Y80 covers 2 and 3 m³/h rated-flow families; Y90 extends the choice from 2 to 15 m³/h. Select by the actual flow, total head and well clearance.

PRODUCT INFORMATION
Built for submerged, multistage lifting.
The right series is determined by the well and operating point—not motor power alone.
Head from repeated stages
Impeller and diffuser stages raise pressure. Use the Q–H curve to check the head available at required flow.
Oil-filled motor
The submerged cylindrical motor drives the stage stack. Confirm voltage, cable and protection for the ordered model.
Bore clearance matters
Check the pump's actual outside diameter against the well casing, including the cable and installation tolerance.
APPLICATION FIT
Start with the well, then the curve.
Dynamic water level, pipe losses and required outlet pressure define the total head. Well diameter determines which pump can be installed safely.
TYPICAL DUTIES01 02 03 04
Groundwater supply
Use the required outlet flow and drawdown level to calculate the duty point.
Farm irrigation
Match the operating flow to the irrigation zone and its pressure losses.
Livestock watering
Confirm the daily demand and storage or trough-filling schedule.
Long-head water transfer
Include lift, delivery-pipe friction and outlet pressure in total head.

Impellers and diffusers
Repeated stages add head; the stage count changes with the selected model.

COMMON QUESTIONS
Before specifying a QJD pump
What must be confirmed before quotation?
Provide bore diameter, static and dynamic levels, required flow and pressure, pipe details and power supply.
Is rated head the same as the operating head?
No. Selection should use the pump curve at the required operating flow and calculated total dynamic head.
