3'' deep well submersible pump

Application: ATQJ series submersible pump is suitable for farm irrigation, sprinkling, fountain, rainwater recycling system, mining drainage, emergency rescue and disaster relief, urban water supply, enterprises and government institutions water lifting. Advantage: Scientific design, high head for single stage impeller, steadily operating and low noise.Superior cast iron as its raw material, scientific casting method ensures the compactness of the molecular structure of castings.CNC lathe precision machining ensures parallelism and perpendicularity of all the parts and also the pump’s concentricity, extending its service life.Rigorous testing, well installation and full load performance test.The service life of the improved rubber bearing liner (technological secret) is 2 times longer than that of common bearing liner.The material of the pump shaft: general chromium-plating, 2Cr13, stainless steel 431, stainless steel 631, model, etc.Material of impeller: stainless steel 304, 316, 316L, tin bronze and aluminum bronze, etc.Some of our products produced by introducing the Germany Ritz technology, increasing the pump’s outer diameter, meanwhile meeting the customers’ needs of high head submersible pump.Motor parameter and service condition: The motor must be submerged into water in vertical form with a depth no more than 70m and the lower distance to the bottom of the well is no less than 5m.The motor will operate continuously and is not suitable for frequently start. The soft-start mode is preferred and then reduced-voltage starting. The starting time should be controlled between 5-25s according to different power, while the soft-stop time should be controlled between 60-180s according to the head and pipe length... The soft-stop mode is also preferred.If it is used in special circumstances, such as mining rescue, the submerged depth could be extended appropriately, then it must be put on records, or else it will not be within the warranty period.Power Supply: 380v/50Hz 660v/50HzIf you need special voltage or frequency, please inform us in advance.Installation form: The normal installation form is vertical. If the actual condition doesn't allowed the vertical form, you can contact the manufacturer to choose the motor of horizontal installation form, however, its service life will be less 40% than that of vertical installation form.Medium Range: Clean water, chilled/cold water, rainwater, underground gushing water of mining, drinking water, mineral water, etc.Water temperature range: +5°C +25°CSolid content (mass ratio): ≤0.01%PH: 6.5-8.5H2S content: ≤1.5mg/LCl- content: ≤400mg/LThe full set must be submerged into water absolutely.
