Used STOKES 412 #9007281 for sale

STOKES 412 is a dual stage, direct-drive rotary vane pump. It is designed to deliver oil-free air and vacuum applications that may require high vacuum levels. The pump is lubricated with a special liquid lubricant, which helps to reduce wear and tear while ensuring longevity and service life. The pump operates with a continuous-duty rating and features two stages of vacuum production. The first stage of the pumping cycle is a direct-drive rotor, which is powered by a motor intended to meet a wide range of CFM requirements. The direct drive rotor is connected to an impeller that emphasizes airflow to produce a given vacuum level. During the second stage, the down-stream pressure is dropped by the smaller vanes, resulting in more efficient transfer of air. As the air is pulled through the inlet, the lubricant inside the casing helps to reduce friction and heat. The design of 412 includes a total of eight curved vane sleeves that are sealed with an o-ring to create a secure seal. This seal helps minimize any possible leakage during operation and ensures that the correct amount of volume is being delivered. The pump is designed with a high- efficiency mechanical seal to reduce energy consumption while maintaining a high level of performance. The design also allows for flexible operations with its adjustable flow rate. It also includes an anti-bounce enclosure to reduce noise and vibration during operation. STOKES 412 is designed with safety in mind, using both manual and automatic controls. The manual system features an emergency stop feature, and automatic controls offer protection against overload protection and motor overheating. In addition, the motor windings are sealed to eliminate dust contamination and protect against damage. 412 is a reliable and efficient pump that is built to deliver oil-free air and vacuum applications in a wide range of industrial and laboratory settings. Offering adjustable flow rates, smooth operation, and reliable performance, STOKES 412 pump offers a reliable and economical solution for any air and vacuum application.
