ZLFG Oil Pressure Quantitative Dispenser

Short Description:

Also called volumetric type, it is a pressurized action type. The pressure grease delivered by the lubrication pump pushes the piston in the measuring piece, and the grease that has been stored in the chamber of measuring part forcibly pressur to the lubrication point. When the system is unloaded, re-storage the grease in the chamber to prepare for the next work. The system must be operated intermittently and the associated lubrication pump must have an unloading function. The lubrication pump has a working cycle, the measuring parts only make oil once, and the distance between the measuring parts is far, near, high, low, horizontal or verticalhas no influence for oil outlet. Accurate measurement, quick action , Smooth drain, the check valve prevents oil from flowing back.

Timed, Quantitative, Scientific Transport


ZLFG volumetric distributor, stores oil when the system is pressurized, and be oiling when the system is depressurized. This series can quantitatively deliver the lubricating oil to each lubrication point according to the specified main oil quantity specification. ZLFG series have two outlets, three outlets, four outlets, five outlets, and four outlet ports. They are widely used in lubrication systems for printing, plastics, packaging, cnc machine and other mechanical equipment.

The working principle

1 The oil pump starts to run, the oil is delivered, and the system pressure begins to rise.

2 The pressure oil in the system forces the umbrella valve to close, and the oil enters the oil cavity, forcing the piston to overcome the spring force and start to rise, while indicating and extending.

3 The system pressure reaches the rated value, the piston moves to the top, and the oil storage is completed.

4 When the oil pump stops working, its pressure relief valve opens automatically, so that the pressure oil in the oil injection pipe is relieved through the pressure relief valve, so that the oil pressure in the oil chamber is greater than the oil pressure in the system, the one-way valve moves to open the oil outlet, the piston is in the spring Start to recover under the action of force. The oil in the oil cavity is discharged through the oil outlet, and the indicator rod retracts.

5.Oil oil cavity after the row, one-way valve under the action of spring force closed oil outlet, finished oil discharge.  

ZLFG volumetric distributor can use For HTD type electric lubricator, 2L, 3L, 4L,6L. Different lubricator tpye selection is based on its application and host system. Optional accessories contain level switch, pressure switch, which can connect with the host system, to realize integrated interval, lubrication and alarming. Lubrication time can be set freely by lubricator, and they look well.
