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.
SSV series single line progressive distributor applies to the single equipment or small sized grease or oil single line concentrated lubricating system with PN under 30MPa. The piston in its shell distribute the lubricating grease input from the entrance with a scheduled volume reliably and compulsorily. There are grease outlets on both left and right side of this type of distributor. The installation dimension of different number of outlets is the same. Derive and unite the grease outlets to increase feeding volume, which can be connected to manual, pneumatic or motor driven lubricating pump to constitute a simple and inexpensive small sized concentrated lubricating system. And it can also be connected to the single line or dual line distributor of a large sized concentrated lubricating system for secondary distribution as an auxiliary distributor.
Nominal pressure (MPa)
Rated flow of each outlet (ml/cycle)
Working pressure (MPa)
Use grease with minimum cone penetration 265(25℃，150g) 1/10mm (NLGI0#~2#) or lubricating oil with minimum viscosity grade N68.
Resolution to common faults
1. Distributor does not work.
Check if there is pressure grease delivered in the grease supply pipeline or not; if lubricating point is plugged or not; if grease supply pipeline is pressed flat; if impurities enter grease feeder. Resolve them after the reason is found out and removed.
2. Leakage at the moving indicator adjusting unit.
Dismantle the restrictor body, and check if seal ring has been used for a too long time or it is used in an higher environmental temperature than specified or not. Replace seal ring after the reason is found out.
Blocking occurs in the device or any connected bearing. First check if the lubricating pump is working or not, and if lubricating grease is supplied to the main distributor. If lubricating grease overflows when the feeding port joint of distributor is opened, it proves that the distributor is the source of failure. Connect and tighten the feeding port joint, and open the feeding port joints of subordinated bearings one by one. If lubricating grease overflows, it means the bearing is blocked.
When blocking occurs in the distributor, the distributor should be replaced. In emergent situation, the distributor can be dealt with according to the following conditions.
1. There should be a clean working place.
2. Dismantle the joints at each grease feeding port and grease outlet.
3. Unload the screw plugs at the two sides of piston holes.
4. Push the piston by a soft piston rod (diameter smaller than 6mm, and use a plastic rod as possible).
5. Inject, blow and wash the distributor body with compressed air.
6. Check the flowing passage and inclined holes in the distributor with a thin iron wire (Φ 1.5mm).
7. Wash, inject and blow the distributor body again.
8. Replace copper cushion rings and re-assembly the distributor.
9. Check the newly-assembled distributor with a manual pump when the initiating pressure of distributor should not be higher than 2.5MPa. If the initiating pressure is higher than 2.5MPa, the distributor should be replaced.
