XR650 Screw Vacuum Pump: 2026 Complete Industrial Operation Guide

Core Definition & Key Performance Specs of XR650 Screw Vacuum Pump

At the very start, XR650 screw vacuum pump refers to Xinrun’s 650m³/h displacement oil-free dry screw vacuum pump for heavy-duty industrial vacuum processing. It adopts high-precision helical rotor profile without any medium inside the pump cavity, eliminating oil contamination risks completely.

In practice, more than 1200 units of XR650 have been deployed across 17 industrial sectors globally by 2026, with an average continuous non-failure operation period reaching 28000 hours. 2026 independent third-party testing data from China Vacuum Equipment Association shows its volumetric efficiency is 19% higher than the industry average for same-displacement dry screw pumps.

Q: What are the exact parameter indicators of the XR650 screw vacuum pump?

Standard parameters include: ultimate pressure 0.1Pa, rated power 15KW, noise ≤72dB(A), cooling method air + water dual option, operating ambient temperature range -10℃ to 45℃, total weight 420kg, connection size DN80 inlet and DN65 outlet.

Q: What core technologies are adopted for this model?

It uses our self-developed 5-axis CNC machined dual screw rotor with surface hardness treatment, no-contact synchronous gear design, intelligent temperature and vibration real-time monitoring sensor module that connects to factory MES systems automatically.

Step-by-Step Installation & Commissioning Guide for XR650 Screw Vacuum Pump

Following standardized installation steps can reduce post-installation failure rate by 87%, according to our 2026 field service case statistics.

1. Place the unit on a 100mm thick flat concrete foundation with 1m reserved space around all sides for heat dissipation and later maintenance operation
2. Connect inlet and outlet pipelines with soft shock-absorbing connectors to avoid vibration transmission to the whole system, add a dust filter at the inlet if you are processing dusty gas
3. Connect power supply to the dedicated 380V/50Hz industrial circuit with independent overload protection, connect cooling water pipe if you select water cooling version, adjust water pressure to 0.2-0.3MPa
4. Power on the unit for 3 minutes no-load test run, check if rotor operation has abnormal friction noise, confirm ultimate pressure can reach below 1Pa within 15 minutes
5. Connect the unit to your vacuum processing system and do 2 hours full-load operation test, record temperature and vibration data to finish commissioning

Q: What common installation mistakes should be avoided?

Common mistakes include: installing the unit near high-temperature heat sources, using too thin inlet pipeline that causes flow restriction, not setting up ventilation for the pump room leading to overheating, skipping no-load test before full load operation.

Q: Can the XR650 be installed outdoor?

Yes, you only need to add a custom rainproof cover provided by Xinrun, ensure the ambient temperature does not exceed 45℃ in summer, and add anti-freezing treatment for the water cooling system in winter to avoid pipeline cracking.

Industry consensus from 2026 Global Vacuum Equipment Application Report shows that proper installation and commissioning can extend the service life of a dry screw vacuum pump by 40% on average.

Main Application Scenarios of XR650 Screw Vacuum Pump

From real cases we handled since 2023, the XR650 model performs far better than liquid ring vacuum pumps and oil-sealed vacuum pumps in multiple high-purity processing scenarios, with zero secondary pollution complaints in the past 3 years.

Q: Is this model suitable for pharmaceutical industry production?

Absolutely. Its full oil-free structure meets GMP production requirements, it is widely used for vacuum drying, degassing, and material conveying in API and oral solid dosage production lines, and can fully avoid oil pollution risks to pharmaceutical products.

Q: Can the XR650 handle corrosive gas in chemical processing?

The standard version can handle general non-corrosive clean gas, while we provide optional PTFE anti-corrosion coating on the pump cavity and rotor surface, making it fully compatible with weak acid, weak alkali volatile gas for chemical distillation and recovery processes.

Low-Cost Daily Maintenance Tips for XR650 Screw Vacuum Pump

In practice, simple daily maintenance operations done by your own on-site operators can reduce annual maintenance cost by more than 60%, no need to invite professional engineers every time for routine checks.

Core routine operations include checking cooling system blockage once per month, replacing the exhaust filter every 18 months, checking synchronous gear lubrication oil level every 3 months, cleaning the inlet filter screen every 2 weeks.
