Changzhou LangO Machinery and Technology Co.,Ltd is a professional lubrication pump manufacturer and exporter in china, that is concerned with the design, development and production of lubrication equipment.
This manual lubricating pump is a small sized lubricating pump by manually pulling the hand shank to discharge grease which can be installed on the wall plate or rack of machine. It constitutes manual terminal type concentrate lubricating system together with dual line grease feeder.
It applies to the single equipment small sized device with relatively lower lubricating frequency (generally feeding interval of more than 8 hours), piping (DN 20) length of no longer than 35m and the number of lubricating points not exceeding 50 as a unit of grease concentrated lubricating system to supply and deliver lubricating grease
Nominal pressure (MPa)
Volume of conservator (L)
Use grease with minimum cone penetration 265(25℃，150g) 1/10mm. Working environment temperature is 0~40℃.
1. When the hand shank of reversal valve is pushed to the limit position, the main pipeline Ⅰ will supply grease.
2. Swing the hand shank to move forward and backward and the pointer of pressure gauge fluctuates, which shows that the grease feeder is working.
3. The pressure gauge on the pump indicates that the pressure value increases stably, which shows that all the working of system grease feeder is completed.
4. Operate the hand shank of reversal valve to reverse so as to make the main pipeline Ⅱ supply grease, and operate in accordance with section 2 and 3.
5. Reverse the reversal valve, unload the pipeline pressure to make preparation for the next cycle and push the hand shank to be vertical.
