Products Description

A rotary vane pump is a positive-displacement pump that consists of vanes mounted to a rotor that rotates inside a cavity. In some cases these vanes can have variable length and/or be tensioned to maintain contact with the walls as the pump rotates. It can endure short periods of dry operation, and are considered good for low-viscosity fluids.

UV series rotary vane vacuum pump offers an excellent ultimate with good pumping speeds as well as superior vapour handling capabilities and quiet operation. It is usually used with distillation, evaporation, reaction equipment.

-Advanced technology to keep high ultimate pressure with gas ballast on -up to 63 CFM / 25L per second -Designed with rational structure, safety and reliability -With high flow rate, high ultimate pressure and low noise level -Free of oil leakage and easy for maintenance -Adopts KF series flange for joint with exhaust sheath to prevent any infiltrating during operating

WVP-series water aspirator vacuum pump uses water to pull a vacuum. No oil is required. Each vacuum port pulls vacuum separately allowing for either two separate applications or connect them together for double the vacuum. This pump can also be used to re-circulate water through the back ports if needed.

- All major valves and parts made of PTFE - Corrosion-resistant, non-polluting - Cyclically use water to reduce the water consumption - Be a vacuum pump or circulating pump - Novel appearance, easy to operate - Low noise, stable performance

A diaphragm pump is a positive displacement pump that uses a combination of the reciprocating action of a rubber, thermoplastic or Teflon diaphragm and suitable valves on either side of the diaphragm (check valve, butterfly valves, flap valves, or any other form of shut-off valves) to pump a fluid.

Diffusion pump is a practical vacuum equipment to seal the pumped vessel and remove all kinds of gases which have no chemical reaction to the working fluid in the high vacuum system. It uses a high speed jet of vapor to direct gas molecules in the pump throat down into the bottom of the pump and out the exhaust. It is widely used in both industrial and research applications. Most diffusion pumps use silicone oil or polyphenyl ethers as the working fluid.

-A high pumping speed of 80L/sec -Compact design makes it easier to integrate into space-constrained devices -Air-cooling design, no water need -Higher pumping speeds, throughput and tolerance fore-pressure -Excellent back-streaming characteristics -Low ultimate pressure, long-term reliability

Turbomolecular pump is a type of vacuum pump, superficially similar to a turbopump, used to obtain and maintain high vacuum. These pumps work on the principle that gas molecules can be given momentum in a desired direction by repeated collision with a moving solid surface. In a turbomolecular pump, a rapidly spinning fan rotor 'hits' gas molecules from the inlet of the pump towards the exhaust in order to create or maintain a vacuum.

- Exceptional pumping speeds (600L/s) and compression ratios - Huge install base of turbopumps with proven reliability - Individual intelligent controller with built-in protections - Fully end user serviceable - Extended lifetime and low cost
