Why is the ATACH‑manufactured TKG‑series vertical inline explosion‑proof VFD‑driven hot‑water pump superior in build quality and offers more consistent performance parameters compared to the standardTime：2026-08-22 The detailed advantages are listed as follows: 1. Performance Parameters Take the conventional ISG80-200 vertical inline pump as an example. It is rated at 50m³/h flow rate and 50m head on the nameplate. However, most pump manufacturers actual test data shows its real flow rate only reaches around 40m³/h, with a parameter inflation of approximately 20%. In HVAC applications, this insufficient flow will lead to inadequate water supply and poor circulation for chiller units, seriously compromising the overall performance of the entire system. In contrast, the ATACH TKG80/200-15/2 vertical centrifugal pump delivers 100% rated or even exceeded performance. Official test reports can be provided prior to delivery upon customer request. 2. Material Options Conventional ISG80-200 pumps are only available with limited material options: cast iron, stainless steel 304 and 316. The ATACH TKG80/200-15/2 supports a full range of premium materials to suit diverse working conditions, including cast iron, ductile iron, carbon steel, SS304/304L, SS316/316L, super duplex steel 2205/2507, and alloy 904L. 3. Mechanical Seal Configuration The standard ISG80-200 pump is only equipped with a conventional 109/MG1 single mechanical seal, which fails to adapt to high-temperature and wear-resistant working scenarios. By comparison, the ATACH TKG80/200-15/2 can be fitted with cartridge mechanical seals, as well as double mechanical seals with full API682 flush plans, ensuring reliable and leak-free operation under harsh conditions. If you have used ISG series inline pumps and been dissatisfied with their actual performance, we recommend upgrading to the ATACH TKG series. We guarantee stable, high-quality performance that will meet your operational expectations. |
