Used PFEIFFER / BALZERS TMH 521 #9002220 for sale

PFEIFFER / BALZERS TMH 521 vacuum pump is a rotary vane pump, also known as a rotovane pump, used in the vacuum technology industry. BALZERS TMH 521 is a two-stage pump that has the capability to increase the compression ratio and achieve a deeper vacuum. The ultimate vacuum achievable with this pump can be as low as 10-4 mbar. The unit is constructed with two cylinders, a rotary vane sliding vanes, and a pair of counter-rotating eccentrics. It uses an externally-fed oil lubrication system which keeps the vanes free of friction and wear during operation. This allows for increased pump protection and prolonged service life. PFEIFFER TMH 521 is capable of pumping both clean gases such as air, argon and helium, as well as condensable gases such as hydrocarbons and carbon dioxide. The pump is equipped with a roughing valve and a silencer which helps to reduce the noise generated during operation. TMH 521's oil-sealed design helps to ensure that there is no contact between the pump cavity and the fluid to be pumped. Additionally, the unit is designed with a low-vibrations process, enabling the pump to maintain precise rotational speed. This technology also helps to minimize equipment wear and tear and environmental impact. Furthermore, PFEIFFER / BALZERS TMH 521 has a maximum pumping speed of 521 m3/h. The unit is V-belt driven, allowing it to be easily connected to other machinery or equipment. It has a power rating of 5.5 kW and runs on a nominal voltage of 400 V/3 - 50 Hz. BALZERS TMH 521 can also be connected to other motor-driven accessories for automatic or semi-automatic operation.
