Description:
4QJ-G series advanced permanent magnetic brushless motor driven high-speed well submersible electric pump (herein-after referred to as 4QJ pump), the pump consists of three main parts: pump body, motor and controller, the pump body is located in the upper part of the pump as a multi-stage centrifugal impeller-guided impeller structure; the motor is located in the lower part of the pump as a three-phase oil-filled permanent magnetic synchronous brushless motor structure, the continue running max. adjustable speed could reach 6500 rpm, with features of small size, high efficiency, wide voltage and long working life. the controller is a special equipment matching the corresponding electric pump to control and protect the motor.
Pump Features:
- Stainless steel case
- Sand resistant fluid structure
- Reinforced high hydraulic strength and durability
- Reinforced screen structures, no deformation
Motor Features:
- Small size and light weight
- High efficiency and energy saving, three phase oil-filled permanent magnetic brushless synchronous motor.
- Motor rotor, dynamic balance precision, lower the vibration, operation stable and longer working life.
- Double mechanical seal system
- Advanced permanent magnet materials, no demagnetize.
- Oil cooled and lubricated 100% copper wire motor, power stronger and stable.
- Spline end reinforced by special materials
- Wide voltage: 190V to 530V operation
- High speed, max adjustable speed: 6500 rpm
MPPT Inverter Control Features:

- Water level control: auto start and stop with float switch
- Pressure Control: auto start and stop with pressure sensor
- Soft start and Auto frequency conversion functions
- Timing function
- Constant voltage function
- Multiple protections for motor
Due to the high rotation speed of motor and multi-stage impeller structure of pumps, the advanced 4QJ pump has the advantages of small volume, light weight, high head, etc. It is widely used in agricultural irrigation, garden sprinkler irrigation, water extraction from underground water source, industrial production, civil engineering, environmental engineering water use and other occasions.
Working Conditions
The 4QJ pump should be able to work continuously and normally under the following operating conditions
- Max. submersible depth: 150m;
- Liquid temperature: 1℃～40℃;
- PH value of the liquid: 6.5 to 8.5;
- The mass ratio of solid impurities does not exceed 0.01%, and the particles are not larger than 0.2mm;
- Controller input three-phase voltage operating range 190VAC ~ 530VAC, DC voltage operating range 300VDC ~ 750VDC.
