【75QJ2 type stainless steel multi-stage submersible pump model description】
1,75QJ pump impeller, the use of PC or POM (polycarbonate material) and commonly known as "race steel" of the polymer wear-resistant materials, stamping, pressure injection made, wear resistance, antioxidant, durable , And has no rust, no pollution characteristics.
2, the water section built a complex type of "check valve", can effectively prevent the "water hammer" phenomenon and return sediment precipitation, so that the pump starts more easily, effectively extend the motor life, the use of more durable.
3, submersible motor shell made of stainless steel, the overall modular production, structural precision, insulation and mechanical noise are all similar to the quality of international quality products, in line with the European standard value. The internal use of high-quality alloy thrust bearings, multi-sealed and equipped with pneumatic balance back pressure device, so that the operation more balanced, more efficient and more durable.
【Product performance】
Submersible pumps:
① stainless steel, HT200 cast iron, green brass pump head and pump seat.
② wear resistance superior POM impeller, PC material guide shell.
③ stainless steel pump body, sleeve, the central axis.
④ stainless steel coupling.
⑤ stainless steel screws, gauze, wire cover.
⑥ POM synthetic material high performance check valve, effectively prevent the impact of water on the shell and the impeller, the use of more durable.
Submersible motor:
① deep well series of motor, single-phase series can be built-in capacitor
Insulation class F
③ stainless steel, HT200 cast iron, environmentally friendly brass motor cover products
【Pump Features】
① independent floating impeller structure, effectively reduce the axial force on the motor, competent multi-level high-lift use.
② pump body diameter is small, large flow, high head, suitable for small diameter deep wells, can significantly reduce drilling costs, more suitable for industrial, construction water.
③ pump head built-in high reliability of the injection check valve, effectively prevent the shutdown of the "water hammer" impact.
④ stainless steel shell, alloy rubber bearings, abrasion resistance and strong.
