SB-M manual lubrication pump is a manual reciprocating type with high working pressure at home and abroad.It has a unique structure. There is an oil scraping device in the oil storage barrel. When the handle is pulled back and forth, the oil scraper scrapes off the grease on the barrel wall, stirs and presses the grease to the oil suction port to strengthen the flow of grease and prevent grease Aging greatly improves the suction phenomenon of the oil suction port and enhances the reliability of the pump. This product is equipped with an exhaust valve. When the grease is mixed with gas, the exhaust valve connector can be unscrewed.Keep pulling the handle until the gas is exhausted to ensure the normal operation of grease feeding. SB-M manual lubrication pump is used in the progressive centralized lubrication system to distribute lubricant to each lubrication point through a progressive distributor.It is widely used in centralized lubrication systems for light industrial machinery such as metallurgy, forging, rubber, petroleum, chemical, construction, and lifting.
