Provide high quality water pump products to customers worldwide.
Product Overview
The Q(D)X-H aluminum-cased submersible electric pump (hereinafter referred to as the electric pump) consists of three parts: a water pump, a seal, and a motor. The motor is located at the top of the electric pump and is a single-phase or three-phase asynchronous motor. The water pump is located below the motor and has a centrifugal impeller and volute structure. A double-end face mechanical seal plus a stuffing box oil seal is used between the water pump and the motor. The mechanical seal acts as a dynamic seal, and each fixed stop seal uses an oil-resistant rubber "O" ring for static sealing. The entire pump uses stainless steel bolts, and the cast iron pump body is electrophoretically treated to effectively isolate air and water, prevent oxidation, and extend service life. The electric pump has a built-in thermal protector to prevent the electric pump from burning out.
Operating Conditions
● The liquid temperature of the water source is less than 40°C.
● The pH value of the medium is between 6.5 and 8.5.
● The power frequency is 50Hz, the voltage is 220V for single-phase AC and 380V for three-phase AC, and the voltage fluctuation range is ±10% of the rated value.
● The water contains no more than 0.1% solid impurities, particles are no larger than 0.2mm, and the submersion depth does not exceed 5m.
Features and Applications
Q(D)X-A series pumps are small and lightweight, suitable for water pumping in rural wells, irrigation, aquaculture aeration and water supply, garden spraying, and water supply in hotels, canteens, and other buildings.
