Q&A

Products Features:

It can run at full speed under atmospheric pressure and ultimate vacuum.

A single stage can achieve a higher vacuum degree, with an ultimate pressure of 2-5Pa.

There is no oil or water in the working chamber of the pump that contacts the process gas.

The rotors do not touch each other, reducing wear; the rotors, housings, and flow-through parts can be coated with anti-corrosion coatings such as Teflon and Hastelloy.

The gas channel in the pump is short and can be exhausted quickly.

It can be operated alone or as a fore-stage pump.

   Dry screw vacuum pumps are available in two types: equal pitch and variable pitch, also known as external compression screws and internal compression screws. Compared with equal pitch screws, variable pitch screw pumps have lower exhaust temperature and higher efficiency.


What is the warranty policy?
Warranty certificate by beneficiary for a period of 12 months from the date of commissioning or 18 months from the date of shipment whichever is earlier.Any faulty part/components found due to manufacturing dafects during warranty period will be replaced at free of costs. Warranty policies for different models of machines may vary depending on the configuration. You can ask DREAM sales engineers for specific details.
What are some of the lubrication methods for pumps?
Oil-Injected or oil-free are available.
How do you choose the right pump?
It is necessary to inform the sales engineer about the working pressure, exhaust flow and power, as well as other necessary parameter information.
How can I choose the bump? Oil-injected or oil free?
Depending on your industry and production industry requirements, whether there are oil content requirements.
How about the performance of the vacuum pump of DREAM brand?
DREAM brand vacuum pump has high temperature resistance, strong stability, low noise and long-term stable operation.
What are the main features of the DM-series Roots vacuum pump?
The DM-series Roots vacuum pump features an oil-free design, high efficiency, low noise levels, and the ability to handle a wide range of vacuum applications. It is also known for its reliability and durability.
In which industries can the DM-series be applied?
The DM-series Roots vacuum pump is suitable for use in semiconductor manufacturing, vacuum coating, vacuum drying, scientific research, and aerospace industries, where a high-purity vacuum environment is required.
How does the oil-injected rotary vane vacuum unit differ from the DM-series?
The oil-injected rotary vane vacuum unit uses oil for lubrication and sealing, which can provide higher vacuum levels and better performance in certain applications. It is ideal for industrial processes that require continuous operation and higher vacuum pressures.
What maintenance is required for the DM-series Roots vacuum pump?
Regular maintenance includes checking the seals, cleaning or replacing filters, and inspecting the internal components for any signs of wear or damage. It is recommended to follow the manufacturer's maintenance schedule and guidelines.
How often should the oil be changed in the oil-injected rotary vane vacuum unit?
The oil should be changed at regular intervals, typically every 3000 hours of operation or as recommended by the manufacturer. Regular oil changes ensure optimal performance and prevent contamination of the vacuum system.
Can the DM-series Roots vacuum pump handle corrosive gases?
While the DM-series is designed for a wide range of applications, it is not specifically designed to handle highly corrosive gases. For corrosive gas applications, special materials or coatings may be required.
What is the expected lifespan of the DM-series Roots vacuum pump?
With proper maintenance and care, the DM-series Roots vacuum pump can have a long lifespan, typically ranging from several years to over a decade, depending on the usage and operating conditions.
Is the oil-injected rotary vane vacuum unit suitable for food processing applications?
Yes, the oil-injected rotary vane vacuum unit can be used in food processing applications where vacuum packaging or vacuum drying is required. However, it is important to ensure that the oil used is food-grade and complies with industry standards.
Can the DM-series Roots vacuum pump be used in a high-temperature environment?
The DM-series Roots vacuum pump is designed to operate within a certain temperature range. While it can handle moderate temperatures, it may not be suitable for extremely high-temperature environments. It is important to check the specifications and consult with the manufacturer for specific temperature limits.
What kind of support and warranty does Dream Compressor provide for their vacuum pumps?
Dream Compressor typically offers comprehensive support, including technical assistance, spare parts, and a warranty on their products. The specific terms and conditions of the warranty may vary, so it is recommended to check the manufacturer's website or consult with a sales representative for detailed information.
