Product Description

Roots pump is a kind of vacuum pump without internal compression. It is a vacuum pump that realizes air extraction by moving gas under the pushing action of synchronous and reverse rotation of a pair of "8" shaped rotors in the pump cavity. Generally, the pumping rate is large and the power of the motor is small, so the front pump is required to pre pump. After the front pump reaches the specified vacuum degree, start the roots vacuum pump to improve the pumping speed and vacuum degree. Its structure and working principle are similar to roots blower. During operation, its suction is connected with the evacuated container or the main pump of vacuum system. There is no contact between rotors of Roots vacuum pump and between rotors and pump casing.

Custom Attributes

1.The running parts in the pump have no friction, no lubrication, and there is no oil in the pump cavity, so a clean vacuum can be obtained.
2.Two leaf involute cycloid profile, high-precision machining to ensure smooth and quiet operation.
3.The gas in the pump chamber flows vertically, which is conducive to the discharge of dust and condensate in the pumped gas.
4.The high-strength rotor with complete symmetry and precise dynamic balance operates stably and reliably.
5.High precision gear, imported bearing, low vibration and noise.
6.The new omni-directional three-dimensional water-cooling jacket design can effectively cool the pump body and greatly prolong the service life of the pump.
7.The overflow surface can be plated with shackles, Hastelloy and PTFE, which can adapt to corrosive environments with different strengths.
8.It is convenient to form roots vacuum unit with liquid ring vacuum pump, rotary vane vacuum pump and dry vacuum pump.

Product Parameters

Applications

Widely used in vacuum metallurgy (smelting, degassing, rolling), chemical industry (vacuum distillation, concentration, solvent recovery), food industry (vacuum packaging, freeze-drying), pharmaceutical industry (vacuum drying, sterilization), electronic component manufacturing, and other fields. Suitable for all processes requiring medium and high vacuum environments, especially for occasions where a small amount of water vapor and dust are contained in the extracted gas and clean vacuum is required.

FAQ

Q1. Can I order a sample for performance testing?

A: Yes, sample orders are warmly welcomed. We also provide customized technical matching solutions based on your specific application scenarios.

Q2. What type of front-stage pump is suitable for matching with the ZJP series?

A: For general vacuum requirements, oil-sealed mechanical pumps are recommended; for processes with a large amount of water vapor, liquid ring pumps are more suitable to avoid oil emulsification.

Q3. Is there a MOQ limit for this product?

A: No, the minimum order quantity is 1 unit, which supports sample testing and small-batch procurement.

Q4. How long is the delivery time for mass production?

A: It takes 8-12 working days after the deposit is confirmed; urgent orders can be prioritized, and the lead time can be shortened appropriately.

Q5. Can the product be customized according to special requirements?

A: Yes, we provide OEM/ODM services, including customized inlet/outlet sizes, cooling methods, and control functions. Please inform us of your specific needs in advance.

Q6. What is the warranty period of the ZJP series Roots vacuum pump?

A: We provide a 1-year warranty, covering manufacturing defects and component failures (excluding wear parts and damage caused by improper use).

Q7. How to handle faulty products during the warranty period?

A: Our products are produced under strict quality control, with a defective rate of less than 0.2%. For small quantities of faulty products, we will send replacements with your next order; for batch defects, we will provide repair, replacement, or recall services according to the actual situation.

Q8. How to solve the problem of excessive noise during operation?

A: First, check whether the pump is installed horizontally and stably, and whether the rotor clearance is normal; second, confirm that the front-stage pump is properly matched. If the problem persists, contact our technical support team for professional troubleshooting.
