Description:

The silent oil-free vacuum pump, it is self-designed pump by Shanghai Greeloy; during daily operation, it do not need to add any oil as lubrication, it can operate continuously and stably for a long time. For Greeloy silent oil-free vacuum pump, it has the advantages of easy operation, convenient maintenance, streamlined structure, lower working noise, environmental protection and non-pollution.

 

Proven through endurance testing and long-term use in the marketplace, this is a high performance, stable and durable vacuum pump that is widely used as the basic equipment for obtaining vacuum for a wide range of applications.

 

Silent oil-free vacuum pumps can be used in (including but not limited to) semiconductor manufacturing, optical coating, all kinds of medical equipment supporting, experimental reagent delivery, liquid sample filtration and concentration, solid-phase extraction, etc., it is an important basic equipment for modern advanced manufacturing and laboratory.

 

Working Principle:

The silent oil-free vacuum pump, it is working in an up-and-down reciprocating motion, guiding the air flow through the pump body to form a vacuum. Our silent oil-free vacuum pump can provide a completely clean vacuum environment, it is maintenance free, and no pollutants are generated during operation processing.

 

Advantages:

1、Streamlined structure, durable operation, stable performance, low vibration, low noise, easy to operate, convenient maintenance, no pollution to the environment.

2、Double insurance settings, built-in temperature control and electrical overload protection device to protect the vacuum pump working safety.

3, Comes with a pre-filter, which would filter impurities, remove air vapor, all-round active protection of the pump and extend the service life accordingly.

4No oil, no lubricant, provide a clean vacuum environment, and the application range is wide.

5、Comparing with the same grade of oil lubrication vacuum pump, it could provide higher vacuum degree, and the range is about -60~-90Kpa.

 

Model selection considerations:

1, Vacuum degree: in the purchase of a vacuum pump, the user should first determine the requirements of the vacuum degree, and the pump which selected should provide vacuum be greater than requirement, otherwise if can not meet the normal work of the supporting equipment, the equipment cannot work correctly.

2, Pumping rate:

It is the pumping volume per minute of the oil-free vacuum pump, the rate must be greater than the demanded, it is recommended to exceed at least 20% above, so as to better meet the needs of use. Also need to pay attention to the air flow, which the pump need to suck, make sure whether the air flow would be corrosive or not. Corrosive air flow would corrode the internal surface of pump body; in this case, please remind the sales beforehead, and this oil-free vacuum pump should be made of special materials, that will be a completely customized pump.
