Used LEYBOLD HERAEUS WAU 501 #9386790 for sale

LEYBOLD HERAEUS WAU 501 is a high-performance, rotary vane pump that is used to generate both high and medium-vacuum levels for industrial applications. The pump provides superior pumping speed and reliability with superior performance in comparison to rotary vane pumps of other similar sizes. WAU 501 has a quiet operation, meaning that it can be used in noise-sensitive applications with minimal concern of disruption. LEYBOLD HERAEUS WAU 501 utilizes a simple two-stage design that provides superior pumping performance over single-stage designs. It features a stainless-steel rotary vane with zirconium-coated tips. This design, combined with moderately low running speeds, ensures higher levels of efficiency for the pump and lower operating costs over the lifetime of the pump. The pump also utilizes a gas ballast system, which allows non-condensable gas that enters the pump to be safely mixed with pump oil and expelled via a single port. This helps to reduce wear and tear of the inner components of the pump. WAU 501 is capable of achieving vacuum levels ranging from 0.5 to 10 mbar (mbar is the unit of pressure equal to 100 pascals). It is also capable of pumping speeds up to 500 liters per hour (l/h), though higher speeds may be achieved with the appropriate accessories. Further, the pump features an oil recovery capacity of 1.5 liters, which allows it to efficiently and safely manage pump oil. LEYBOLD HERAEUS WAU 501 features an oil-based lubrication system. This part of the pump helps to further extend its lifespan in high-vacuum conditions. The oil also helps to maintain an even temperature in the pump, which helps to reduce internal wear and tear. For added safety, the pump includes a poppet safety valve that relieves excess pressure inside the pump in order to prevent damage in the case of overpressure. The pump is also equipped with a low-maintenance, self-contained oil sump. This helps to reduce user involvement and maintenance, as well as the need to refill or change the pump oil on a regular basis. Additionally, the pump contains a liquid ring vacuum condenser that helps keep it cool and reduce oil evaporation. Finally, the pump is UL listed and carries a CE certification, both of which demonstrate its quality and commitment to safety. In short, WAU 501 rotary vane pump offers superior performance, reliability, and safety ratings at an economical price point. It is a great choice for medium to high-vacuum applications.
