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.
SSPQ-P series (originally ZV-B series) dual line distributor applies to the grease or oil dual line concentrated lubricating system with PN of 40MPa as a unit of calculating grease feeding. By alternate grease supply by two main supply pipelines, it realizes feeding grease to piston and completes the function of quantitatively distributing grease to each lubricating point. The distributor has three types: distributor with grease feeding screw, distributor with moving indicator adjusting unit and distributor with travel switch adjusting unit.
1. Distributor with grease feeding screw: the feeding volume cannot be adjusted which only can be altered by selecting the grease feeding screw with different feeding indicator.
2. Distributor with moving indicator adjusting unit: the feeding volume can be adjusted between 0 and the rated feeding volume and that whether distributor is working normally or not can be judged by observing the moving indicator adjusting unit.
3. Distributor with travel switch adjusting unit: the feeding volume can be adjusted between 0 and the rated feeding volume, and the grease feeding condition of lubricating points can be controlled by travel switch to send a signal. Only one limit switch adjusting unit can be equipped for a distributor.
"Loss flow" means the flow that make the reversing piston working.
Nominal pressure (MPa)
Working pressure (MPa)
Loss flow (ml)
Flow of each outlet (ml/cycle)
The options of “Collocation with” are: 1, grease feeding screw; 2, moving indicator adjusting unit (limitator); 3, travel switch adjusting unit. The flow of one outlet is double as “Flow of each outlet” when the outlet quantity is odd. Use grease with minimum cone penetration 220(25℃，150g) 1/10mm (NLGI0#~3#) or lubricating oil with minimum viscosity grade N68. Working environment temperature is -20~80℃.
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.
1 For distributor with grease feeding screw (SSPQ1), grease feeding indicator should be specified in the sequence of every couple of grease outlets. If not specified, goods will be supplied based on grease feeding indicator 1.
2 For distributor with moving indicator adjusting unit (SSPQ2), only one limit switch adjusting unit is equipped. Limit switch adjusting unit can be equipped for every couple of grease outlets based on special requirements. The equipping number should be specified and they should be ordered separately.
