The hydraulic main pump is a kind of fluid pump. About the fluid sealing, it usually uses the mechanical seal to contain the fluid within a vessel (typically pumps, mixers, etc.) where a rotating shaft passes through a stationary housing or occasionally, where the housing rotates around the shaft.

Mechanical seals are usually fixed at the point of entry or exit of a rotating shaft. Typically it is used to prevent the leakage of one high-pressure fluid into a lower pressure fluid.

Start

Sonka Company grew out of Global Engineering Machinery.

Time back in 2009, a spare parts shop named GLOBAL ENGINEERING MACHINERY established in Guangzhou City. Soon but stably, it sold its spare parts to more than 30 cities in domestic China in the same year, with the fame spreading far and wide, for the good product quality and service.

At that time the shop mainly sold mainly in seal and seal kits lines: excavator seal kits, loader seal kits, bulldozer seal kits, breaker seal kits and other construction machinery-related seals.

To meet customer’s growing needs on seal kits, in 2013, a new company named Guangzhou Huanqiu Seal Technology Co. LTD was set up to handling the seal factory. Factory manufactures all kinds of seals for construction machinery.
