专用于外侵性流体的离心泵
Friatec改进了那款适用于大流量、耐热、受污染流体介质的垂直离心泵。
GVSN系列立式泵对GVSO系列泵已经做了相当的改进。
通常情况下GVSN泵经常被用于耐腐蚀硫酸、液体二氧化硫、焦油和熔盐等介质，同时GVSO泵可用来固定太阳能发电产业中的新设备。这些设备可以适用于560摄氏度高温的熔盐。这些熔盐主要用于转移和储存的热量。
Friatec声称，目前GVSO泵已经在欧洲的几个太阳能发电厂成功通过测试。适用于高温流体介质的GVSO潜水电泵，主要是由高强度耐腐蚀不锈钢制造。
Centrifugal pump for aggressive fluids
A line of vertical centrifugal pumps suitable for use with aggressive,
heated and contaminated fluids has been developed by Friatec.
The GVSO series of pumps has been developed from the company’s GVSN
Series of vertical pumps.
While the GVSN pumps are typically used for pumping sulphuric acids,
liquid sulphur, tar and molten salts, the GVSO pump can be used being used
to address new applications in the solar power generation industry. These
applications use molten salts with temperatures up to 560°C. The molten
salt is used to help the transfer and storage of the heat.
Friatec says that is has already successfully tested its new GVSO
pumps for several solar plants throughout Europe. The GVSO submersible
pumps, which are suitable for aggressive fluids in high temperatures are
made from high-grade stainless steels with a medium lubricated sleeve
bearing concept.
