Used LEYBOLD HERAEUS D90A #197121 for sale

LEYBOLD HERAEUS D90A is a heavy-duty vacuum pump designed to be used for applications requiring high ultimate vacuum, rapid pumping speeds, noise-free operation and low maintenance requirements. D90A is capable of reaching deep vacuum levels, allowing it to be used for applications from semi-conductor fabrication and mass spectrometry, to space simulators and industrial vacuum metallurgy. LEYBOLD HERAEUS D90A features a single-stage, oil-sealed rotary piston design that utilizes a carbon/ceramic piston and a corrosion-resistant stainless steel housing for durability. The pump is driven by a brushless motor, powered by between 220-240V Saug, making it both efficient and quiet in operation. This motor is sealed against dust and dirt, further reducing any maintenance requirements. A pneumatic door seal helps to ensure the oil-saturated vapours are kept within the pump when it is running. The vast majority of mechanical components on D90A have been designed to allow them to be replaced without tools, reducing the time required for maintenance. The large internal electrical wiring makes it easier to find faults in the system and the configuration ensures that all the contacts are protected from contamination when in use. The variable-speed drive system makes it possible to adjust the pump speed depending on the needed ultimate vacuum levels, while the anti-surging software ensures a smooth, constant flow of and that the motor does not reach its maximum rotational speed, preventing wear and tear on the pump. A pressure relief valve is in place to protect from any overpressure bursts. LEYBOLD HERAEUS D90A is designed to be fed with appropriate lubricants, preventing any lubrication related issues and its four cooling fins along with its integral inlet filter greatly reduce the necessary maintenance of the vacuum pump, ensuring it can run for long periods of time with minimal maintenance required. This efficient design makes D90A an ideal choice for applications that require an oil-sealed, single-stage pumping solution.
