This new sealing technology enhances pump performance
New developments of an innovative sealing technology have been added to the range of Viking Universal Seal Series of Internal Gear Pumps. The result is a more cost-effective sealing option compared to traditional mechanical seals, while also reducing leakage rates compared to using pumps with packing. The new option is also designed for back pull-out, which helps to reduce downtime and simplify maintenance. Available from this company, the new O-Pro seal uses a series of O-rings to create a robust seal and lubrication chamber in a single-piece seal. This new feature can be fitted throughout the Viking Universal Seal Series pumps, which cover flows to 295 m³/h, discharge pressures to 14 bars and liquid viscosities of 20–1,700 cSt at temperatures between –15 to 175°C. — Michael Smith Engineers Ltd., Woking, U.K.
