Release time:
2026-06-16
This 2026 practical guide elaborates core functions, technical parameters, applicable scenarios and operation specifications of the XR650 screw vacuum pump based on 7 years of field test data from XRVacuum. It also makes horizontal comparison with peer products, helps industrial users reduce 30% average operation cost and avoid common using errors.
📋 Guide Overview
This full guide targets production managers, equipment procurement engineers and maintenance technicians who need stable high-performance vacuum equipment for 2026 industrial production scenarios, all data are verified by on-site test of Qingzhou Xinrun Machinery technical team.
Basic Definition & Core Features of XR650 Screw Vacuum Pump
In the opening section, we give the most direct and precise explanation first:
XR650 screw vacuum pump is an oil-free industrial vacuum generator with 650 m³/h rated pumping speed, independently developed by XRVacuum.
In practice, this model uses dual parallel non-contact screw rotors, no oil lubrication inside the compression chamber, to avoid secondary contamination to production materials completely. 2026 industrial equipment test data shows its average energy efficiency is 22% higher than traditional oil-sealed vacuum pumps of same pumping speed grade.
Q1: What is the ultimate vacuum value of XR650 screw vacuum pump?
Actual test shows that the XR650 screw vacuum pump can reach ultimate vacuum of 5×10⁻² Pa under standard working condition, which meets the high vacuum requirement of most semiconductor and pharmaceutical production processes.
Q2: What is the standard warranty period of XR650 screw vacuum pump from XRVacuum?
As official rule published on www.xrvacuum.com, all XR650 units come with 3 full years of whole-machine warranty, and lifetime free technical support from our 24/7 after-sales team.
Correct Startup Operation Steps for XR650 Screw Vacuum Pump
For first-time users, following standard startup process can avoid 90% of common operation faults, reduce the wear rate of screw rotors by 47% according to our 2026 field operation statistics. Please follow the steps below strictly:
- Check the cooling water inlet pressure, make sure it stays between 0.2MPa and 0.3MPa, confirm no water leakage at pipeline joints
- Open the exhaust valve fully before power on, start the pump under no-load status, run it for 3 to 5 minutes to warm up the rotor chamber
- Gradually open the intake valve, adjust the system vacuum pressure to the required working range of your production process
- Check the running current value every 10 minutes in the first half hour of operation, make sure it does not exceed the rated 18A threshold
2026 Parameter Comparison Between XR650 and Peer Screw Vacuum Pumps
To help users make objective purchasing decisions, we list all key performance data of 3 mainstream 600-700 m³/h grade oil-free screw vacuum pumps below, all data comes from third-party industrial equipment testing institution:
| Performance Dimension | XR650 (Xinrun XRVacuum) | Competitor Model A | Competitor Model B |
|---|---|---|---|
| Rated Pumping Speed | 650 m³/h | 630 m³/h | 620 m³/h |
| Rated Power | 7.5 kW | 9.2 kW | 8.8 kW |
| Noise Level (1m distance) | 62 dB | 71 dB | 68 dB |
| Whole Machine Warranty | 3 Years | 1 Year | 1.5 Years |
Industry consensus is that the XR650 screw vacuum pump leads its grade on comprehensive cost performance, the average annual electricity cost saving can reach up to 2100 USD for 24/7 continuous operation scenario.
Main Application Scenarios of XR650 Screw Vacuum Pump
From actual cases of over 120 XRVacuum clients in 2025 and 2026, the XR650 model works stably in more than 12 industrial fields, the most widely used scenarios are listed below:
Q3: Is XR650 screw vacuum pump suitable for pharmaceutical freeze drying production?
Yes, all contact parts with gas of XR650 adopt 316L stainless steel material, completely no oil contamination risk, which fully meets GMP production requirement of pharmaceutical freeze drying process.
Q4: Can XR650 work under harsh condition with a large amount of volatile corrosive gas?
Customized anti-corrosion coating version of XR650 is available, which can handle HCL, H2S and other common corrosive gas, widely used in chemical and new energy material production lines.
Routine Maintenance Schedule for XR650 Screw Vacuum Pump
Following regular maintenance plan can extend the service life of XR650 to over 15 years, our technical team has verified this schedule in long-term on-site tracking tests.
Q5: How often do I need to replace the exhaust filter of XR650?
For normal clean gas working condition, replace the exhaust filter every 8000 running hours, for dusty or sticky gas scenarios, reduce the interval to 3000 running hours.
Q6: What is the allowed operating ambient temperature range for XR650?
The standard XR650 screw vacuum pump can work stably under ambient temperature from -10℃ to 45℃, low temperature or high temperature customized versions are available for special scenarios.
