VD series is a Double stage rotary vane type direct-driven oil rotary vacuum pump equipped with ULVAC’s original multi-voltage motor. This dual stage rotary vane mechanical vacuum achieves lower ultimate pressure
VS series is a single-stage rotary vane oil rotary vacuum pump coupled with a direct-drive motor. VS series is a single-stage rotary vane oil rotary vacuum pump coupled with a direct-drive motor.
PVD series is a compact, double-stage rotary vane oil rotary vacuum pump coupled with belt-driven motor.
From the reliability and ease of use over the years, is a small belt-driven oil rotary vacuum pump has gotten used to a lot of customers. From the low-speed rotation, it performs a quiet and stable exhaust characteristics.
The PKS series models are extremely durable, large oil rotary vacuum pumps with very stable pumping characteristics. High-grade cast iron is used, providing strength and resistance to abrasion. They are used in many applications, in areas ranging from the metal and automotive industries, to the chemical, pharmaceutical and food industries.
This is a rotary blade type vacuum pump that uses lubricating oil. A vacuum pump with low noise, low vibration and high reliability. GLD series is a high-performance type.
This is a rotary blade type vacuum pump that uses lubricating oil. A vacuum pump with low noise, low vibration and high reliability. GCD series is a highly corrosion resistant type.
When the vacuum pump oil is operated over a long period of time, its deterioration contributes to poor performance. Regularly check to see if the oil has decreased or if it is dirty and refill or replace it.
When an oil rotary pump is started at atmospheric pressure, and operated during low vacuum operation, the pump oil is exhausted along with the exhaust gas that is being pumped. This oil-laden exhaust mist, which consists of tiny oil droplets, appears as “smoke” exiting from the exhaust port of the pump.
