Dry-running screw vacuum pumps ULVACWe offer the following model series: The ULVAC LS is an innovative dry-running screw pump that features a pair of tapered steel screws with variable pitch, allowing pumping at near atmospheric pressure. The vacuum pump is up to 1/3 lighter than a conventional screw vacuum pump and is designed primarily for clean applications. However, it can also be used as a vacuum pre-pump of the vacuum systems. ULVAC CR are air-cooled, dry-running vacuum pumps designed for clean and wet processes. The devices are capable of extracting up to 500 g/h of steam (or pure gas). Due to these properties, they are suitable as a vacuum source for vacuum dryers, sputtering equipment and evaporation systems. The ULVAC LR, HR and UR series are specially designed dry-running vacuum pumps that are designated for applications where heated gas or exhaust piping is required. Because of this capability, they are required in PVD processes and CVD coating. They can also be used as acuum pre-pumps for turbo molecular and mechanical booster vacuum pumps. ECO-SHOCK is an accessory for ULVAC LR / HR / UR dry-running vacuum pump models. The device can reduce energy consumption by up to 80%. It supports pumping of air, nitrogen and inert gases, such as argon. It connects to the exhaust pipes. Typical applications of the dry-running vacuum pumps include:

ULVAC mini vacuum pumpsWe offer the following model series: ULVAC DTC are small vacuum pumps designed for laboratory use. All contact parts are made of PTFE or FPM, which allows for pumping of corrosive gases. They are available in four versions with pumping speeds of 20 to 240 liters/min. Key advantages include chemical resistance, easy maintenance and low cost. ULVAC DA is a small universal dry-running vacuum pump suitable for a wide range of laboratory applications from plate handling to non-corrosive laboratory pumping needs. The device allows for a regulation of the pumping speed. The ULVAC DAU/DTU diaphragm mini vacuum pump offers high vacuum with pumping speeds of up to 23 l/min at 60 Hz. It is available in two versions. DTU model - corrosion and hard gas resistant. The vacuum pump can also be used as a vacuum pre-pump for turbo molecular pumps. ULVAC DAP are small vacuum pumps designed for various fine handling operations. The vacuum pumps contain a rubber diaphragm that allows for a very clean and oil-free vacuum environment. The DAP vacuum pumps are available in four versions with pumping speeds of 6 to 18 l/min. ULVAC DOP mini vacuum pumps are ideal vacuum sources for vacuum chucks, tweezers and other automatic handling applications. They are available with pumping speeds of 44 l/min to 140 l/min. ULVAC DIS is a universal "double-wound" vacuum pump that achieves a high level of dry vacuum and operates at atmospheric pressure. Its characteristics include low vibration, low noise and a high pumping speed. The pump can be used as a stand-alone pump or as a vacuum pre-pump for a turbomolecular vacuum pump. ULVAC DISL creates vacuum using a special spiral mechanism. This allows for higher pumping speeds, lower final pressure, lower energy consumption and less noise. The vacuum pumps can reach a pumping speed of up to 520 l/min. . Typical applications of an oil rotary vacuum pumps include:

ULVAC rotary oil vacuum pumpsWe offer the following model series: ULVAC GHD is a closed rotary oil vacuum pump with a motor connected via a magnetic coupling. This ensures that leakage from the shaft seal is prevented, which results in an extended service life of the entire device. The pump is also equipped with an integrated reverse valve to protect against oil backflow. ULVAC GLD is a highly reliable and powerful direct drive rotary oil vacuum pump. It is characterized by low noise and low vibrations. The vacuum pump is equipped with oil backflow protection and a gas ballast to increase the steam pumping power. ULVAC GCD is a corrosion resistant rotary oil vacuum pump designed for pumping toxic and corrosive gases and solutions. It is available in three versions with pumping speeds of 50 to 200 l/min. ULVAC VS are quiet vacuum solutions suitable for continuous operation at high pressures. They are available in water-cooled or air-cooled versions. The vacuum pumps have been designed specifically for low vibration operation. ULVAC VD are large capacity oil rotary vacuum pumps with a quiet motor and easy maintenance. The pump incorporates a forced oil circulation system that ensures a stable pumping speed under atmospheric pressure. ULVAC PVD is a compact belt driven rotary vacuum pump with excellent evacuation characteristics. This vacuum solution features low vibrations, low noise, easy maintenance and consistent pumping power. Typical applications of an oil rotary vacuum pumps include:

ULVAC rotary piston vacuum pumpsWe offer the following model series: ULVAC PKS are robust oil vacuum pumps that utilize the rotary piston technology. The body of the device is made of a high-quality alloy, which provides strength and abrasion resistance. Disassembly and reassembly for maintenance purposes is simple, as are inspections of the exhaust valves. The vacuum pumps are only available in a single-stage design. The pumps can reach pumping speeds of 96 to 420 m3/h (from 1,600 to 7,000 l/min). Typical applications of the piston vacuum pumps include:

Roots ULVAC vacuum pumpsULVAC PRC is a high volume mechanical booster pump for clean applications. The vacuum pump does not use any oil in the pump chamber, resulting in a stable power even when discharging steam or solvents. The PRC-A series models are designed for universal, semiconductor and liquid crystal imaging processes that require extreme purity. Mechanical boosters can increase the pumping speed within the range of 10 kPa and 0.1 Pa. ULVAC PMB-D Roots vacuum pumps are used as mechanical boosters of the pumping speed and input pressure limits. All models are equipped with a direct drive and a universal electric motor with variable speed. Based on particular requirements, the surfaces of the main parts of the pump can be coated to ensure corrosion resistance. The UKVAC PMB-040C & 060C models are suitable for the high volume extraction required by vacuum heating equipment such as melting furnaces or vacuum simulation chambers. ULVAC MBS is a small compact booster vacuum pump with a motor with magnetic clutch. This non-contact seal reduces energy consumption by 60% and ensures zero oil leakage. The advantages of the solution include a small size, light weight, corrosion resistance, quiet and smooth operation and clean vacuum. Typical uses of the Roots vacuum pumps include:
