1. VP series1. VP series
VP series dry piston vacuum pumps feature oil-free economical alloy aluminum design. Oil-free design makes dry piston vacuum pumps ideal for non-corrosive applications. It can be used in a multitude of applications for vacuum generation in laboratories and institutes, such as vacuum filtration, vacuum degassing, vacuum impregnation, vacuum drying chambers, rotary evaporators, distillation, gel dryers, and gas analytical systems.
Key Features :
  • High quality permanent-magnet DC motor drives the piston reciprocating motion to deliver gases at high pressure.
  • Oil-free lubrication design goal for the environment.
  • Aluminum alloy casing makes the product compact and light, with high heat-scattering efficiency.
  • Air flow can be adjusted automatically.

2. GM series

GM series of diaphragm vacuum pumps include the following six models: GM-0.20, GM-0.33II, GM-0.33III, GM-0.50, GM-0.50II, GM-1.00. This series of products have the features of advanced design, wide working range, and long operating life.

GM diaphragm vacuum pumps feature continuous oil free pumping, low noise level, high efficiency, and long lifetime. They are specifically designed for laboratory operations (e.g. rotary evaporators) meeting the highest expectations for precision, reliability and ease of use.


  • It can be in service under the condition of no working medium (no oil) and will not produce any pollution. Moreover, air in the exchange bin is filtered to maintain clean.
  • New technologies and materials are used in production for smooth operation and guarantee the ideal vacuum and high rate of air flow.
  • It operates with minimal friction, heat production, and no friction exhausts. The diaphragm is made of Nitrile Rubber, which resists the corrosion and has long operating life.
  • The self-cooling air draft system is designed in the body. This system can keep the machine continuously running for 24 hours.
  • The system can be regulated by pressure to meet the requirements of vacuum or controllable steady air stream within certain range.
  • Brand name components including the axletrees are used to maintain steady running, low noise and high operating efficiency.

Application Examples

  • Vacuum filtration
  • Filtration Unit
  • Vacuum distillation
  • Vacuum drying
  • On rotary evaporators
  • To extract and transfer gases
  • Gel drying
