Description :
The 2 Inch DC Copper Brushless Submersible Well Pump with a Plastic Impeller is a reliable and efficient pump designed for submersible well applications. Here are some features and benefits of this pump :
1. Brushless motor : The pump is equipped with a brushless DC motor, which offers several advantages such as higher efficiency, longer lifespan, and quieter operation compared to traditional brushed motors.
2. Copper construction : The pump features a copper construction, which provides excellent durability and corrosion resistance. Copper is an ideal material for submersible pumps as it can withstand the harsh conditions of well water.
3. Plastic impeller : The pump's impeller is made of plastic, which is lightweight and resistant to corrosion. The plastic impeller design ensures efficient water flow and reduces the risk of damage or clogging.
4. Energy-efficient operation : The brushless DC motor offers high energy efficiency, consuming less power compared to traditional motors. This results in energy savings and reduces operating costs.
5. Easy installation : The submersible design of the pump allows for easy installation in wells. It typically comes with a cable for power connection and may include fittings or adapters for quick installation.
6. Versatility : While primarily designed for well applications, this pump can also be used for other water transfer tasks where submersion is required, such as drainage or water circulation in ponds or reservoirs.
Advantages :
1.Permanent magnet DC brushless synchronous motor : The efficiency is increased by 15%-20%, saving energy consumption.
2.All 304 stainless steel rotor shafts avoid the risk of shaft breakage.
3.Brass/Stainless steel outlet/connector/oil cylinder, with better corrosion resistance.
4.Japanese NSK bearing,longer working life.
5.The double bearing structure at the bottom of the rotor, using angular contact bearing, can withstand greater axial pressure.
6.Silicon carbide-impregnated graphite mechanical seal, long service life and reliable operation.
7.180°C high temperature resistant copper wire, insulation class F.
8.Cold rolled 600 silicon steel sheet stator and rotor.
9.The magnet is made of 40SH aluminum iron boron, with a temperature resistance of 150oC.
10.304 S/S pump shaft.
11.Controller :
(1)Waterproof grade : IP65
(2)Wide open circuit voltage range
(3)Ambient temperature : -15oC-60oC
(4)MPPT function, solar power utilization rate is higher.
(5)LED displays power, voltage, current, speed, etc. working conditions.
(6)lt can automatically adjust the speed for operation according to the sunlight power, and can also manually adjust the speed for operation according to the actual demand.
(7)Automatic startup and shutdown, without personnel on duty.
(8)Soft start; No impulse current, protect the pump motor.
(9)Over-voltage/undervoltage/overcurrent/phase loss/short circuit/water shortage/high temperature protection etc.
12.2 years warranty.
