SGG Vertical High Efficiency Double Duction Pump
In the 1980s, we successfully developed the SG series single-stage pump with eight major advantages, becoming the first product to be introduced in the heating and air-conditioning engineering fields in China calendar.
After SG series, ISG series, third, fourth, fifth and sixth generation KQL/W series, it will return to high quality and high efficiency SG series in 2021.
SGG Vertical High Efficiency Double Duction Pump
Pump set with high efficiency
Wide and high-efficiency hydraulic model, YE3 series high-efficiency motor.
Good cavitation performance
Some adopt double-suction impellers and semi-spiral suction chambers to reduce the impeller inlet flow rate.
The whole pump configuration is high
SKF bearing + Burgmann mechanical seal + stainless steel impeller.
High quality
Complete machine machining center and factory testing.

| Location | Description | |
| 1 | Motor | IE3 series motors, optional Siemens, variable frequency, outdoor, explosion-proof and other special motors |
| 2 | Clamp coupling | Made of cast steel, strong and reliable |
| 3 | Pump shaft | Standard 40Cr material, chrome-plated sliding bearing position |
| 4 | Mechanical seal flushing pipe | Used for flushing cartridge mechanical seals to increase the service life of the mechanical seals |
| 5 | Pump body | Precision casting, surface electrophoresis paint treatment, gray iron, ductile iron and other materials can be used |
| 6 | Impeller | Precision casting, standard 20Cr13 stainless steel material, optional 304, 316 and other materials |
| 7 | Fasten the screw nut | Used to lock the impeller, made of high-strength steel |
| 8 | Sliding bearing | Made of copper alloy material to reduce friction and not easy to break |
| 9 | Sealing ring | The standard configuration is made of copper alloy, which has low friction, reduces mechanical losses and improves pump efficiency. |
| 10 | Pump cover | Precision casting, surface electrophoresis paint treatment, gray iron, ductile iron and other materials can be used |
| 11 | Containerized mechanical seal | Choose imported brands such as Burgman or John Crane for easy installation and disassembly. |
| 12 | Motor bracket | Surface electrophoresis paint treatment, gray iron, ductile iron and other materials can be used |
The pump body and the pump cover mold are directly processed into the whole body according to the CNC machining center according to the process requirements to ensure that the size error of the mold is controlled within 0.2mm, and the impeller adopts precision metal casting mold.
Five axis five linkage machining center, CNC boring and milling machine and other large high-end processing equipment and special aircraft tooling, in the domestic enterprises in the leading level, is the pump body, pump cover and other parts processing and manufacturing quality reliable guarantee.
The impeller is dynamically balanced to ensure smoother operation of the entire pump.
The pump shaft is adjusted to ensure the mechanical properties and the reliable operation of the pump.
The mechanical seal adopts Burgmann/John Crane, and the stainless steel bushing in the sealing position and the mechanical seal will never rust. The mechanical seal failure rate is reduced from 2% to 0.9%.
The bearings adopt the SKF brand, which has low noise and long service life. Theoretically, it can reach 100,000 hours. The bearing failure rate has dropped from 1.6% to 0.7%.
