Vacuum Pumps

What Is a Laboratory Vacuum Pump?

A Laboratory Vacuum Pump is an auxiliary device used to remove air from a closed test system and create the vacuum conditions required for different laboratory procedures. Liya Test offers both single-stage and two-stage vacuum pump models, providing different flow capacities for a wide range of laboratory applications.

The available models cover a flow range from 42 L/min to 226 L/min. This allows laboratories to select a pump according to system volume, required evacuation rate and test configuration.

Single-Stage Vacuum Pump Models

The single-stage range includes five different capacities.

LT-G0209 provides 51 L/min, while LT-G0210 offers 70 L/min. For applications requiring higher air evacuation capacity, the range continues with LT-G0215 at 100 L/min, LT-G0216 at 170 L/min and LT-G0217 at 226 L/min.

Single-stage pumps can be selected for laboratory systems where this pump configuration meets the required operating conditions.

Two-Stage Vacuum Pump Models

Liya Test also offers five Two-Stage Vacuum Pump options.

The available capacities are 42, 70, 128, 170 and 226 L/min. Model codes range from LT-G0218 to LT-G0222.

The two-stage configuration provides an alternative for systems requiring a different vacuum pump arrangement. The correct model should be selected according to the technical requirements of the connected equipment.

Flow Capacity from 42 to 226 L/min

Flow capacity indicates the amount of air the pump can move over a given period.

A higher L/min value means the pump can evacuate a greater quantity of air per unit time. However, flow capacity alone does not determine whether a pump is suitable for a specific application.

Users should also consider the required vacuum level, test system volume, connection type and operating conditions before selecting a model.

Laboratory Applications

Vacuum pumps can support different laboratory operations such as:

• vacuum filtration systems
• sample preparation
• vacuum-assisted test equipment
• air evacuation procedures
• laboratory drying systems
• general test systems requiring reduced pressure

The exact application depends on the specifications of the connected laboratory equipment.

Selecting the Correct Vacuum Pump

The correct Laboratory Vacuum Pump should be selected according to both flow capacity and stage configuration.

Lower-capacity models may be suitable for smaller systems, while larger test arrangements can require increased evacuation capacity.

Liya Test’s 42–226 L/min model range gives laboratories multiple alternatives for different working requirements.

Overall, the Vacuum Pump Models provide single-stage and two-stage solutions for laboratory systems requiring controlled air evacuation and vacuum generation.
