Refrigerant Freon Transfer/Filling Pump

LYQ250 series single action air pump

We are professional manufacturer for high pressure pumps and valves with high and stable quality, and we have made many pressure testing system solutions for many customers.



LYQ250 series single action air pump, air source pressure is from 0.2MPa (29PSI) to 1MPa (145PSI). Air inlet is G1/2″ (can be changed to other's joint with reducing adapter). The pump body of hydraulic parts is stainless steel, it can adapt water and hydraulic oil, ant its max. Working pressure can reach 434MPa (62934PSI).


 Specifications
1. Low noise noise during operation;
2.Use medium temperature: -40 ° C to 80 ° C;
3.The highest pressure can reach 360MPa (52200PSI);
4.The air source pressure is 0.2MPa (29PSI) to 1MPa (145PSI);
5.The hydraulic end is made of 5.stainless steel pump body, suitable for clear water, oil or other medium;
6.Patent reversing technology, the probability of card pump is extremely low, effectively solving the problem of commutation dead zone
(Another: unique button recovery mechanism design, can also let the pump quickly resume work).
Product application
1.Frame type rugged pressure test device;
2.Hydrostatic pressure, fatigue, and blasting test;
3.High pressure and large displacement pressure test system.
Technical Data
 
Selecting the right pump
1.Data for pump design
The following parameters are required for designing and selecting pumps:

1. Required operating pressure
2. Desired pump capacity at operating pressure
3. Available air drive pressure
4. Medium
5. Temperature of the medium
6. Ambient Temperature

Depending on the application, you may require additional data.For more detailed specification and performance data , please contact us directly by email or call.- we are happy to assist in the designing process.
2.Required operating pressure and pump capacity
Specifications of pump operating pressures are essentially based on an air drive pressure of PL = 10 bar (145 psi). The operating pressure (PB) can be determined by multiplying the pressure ratio of the pump(i) by the available air drive pressure (PL) PB= i × PL.

3.Specifications of pump capacity at the respective outlet pressure can be found in the pump capacity tables following  Medium
The pump model should be selected to match the medium to be pumped, as it is the properties of this medium which determine the requirements for the sealing materials and the wetted parts.
Maximator pumps are suitable for a large variety of media. Standard designs are available for oil and water and for many special media.
4.Dimensions and weight
Some applications require special pump dimensions and weights. Please refer to the tables and option lists for our pump series for more information about this as well as on the availability of the
