Features

--Experience the efficiency of an oil-free pump chamber, ensuring a contamination-free vacuum system that enhances product quality. Say goodbye to oil emulsification issues and the hassle of frequent fluid replacements, while minimizing maintenance costs. This powerful unit achieves a remarkable 5pa on its own and can seamlessly integrate with Roots pumps,
molecular pumps, and more to create an advanced oil-free system delivering superior vacuum capabilities.
--Overcurrent components such as the pump chamber and screw rotor
can be enhanced with nickel phosphorus coatings and Hastelloy alloy infiltration,
making them adept at handling corrosive media. Ideal for chemical and pharmaceutical applications including product distillation, drying, and degassing.
--Effortlessly discharge extracted gases directly from the pump body,
eliminating environmental pressure concerns and simplifying gas solvent recovery.
--Designed for easy maintenance, the pump allows for straightforward cleaning. Simply open the suction and exhaust ports, initiate the pump, and introduce water or cleaning agents from the suction port for a quick clean, no disassembly required.
