35VQ is a medium-large single pump model of VQ balanced vane pump series. Its displacement ranges from 81.6 to 121.6 cm³/rev with a maximum continuous pressure of 210 bar.
Adopting floating side plates and 10/12-vane balanced structure, it maintains high volumetric efficiency, low vibration and quiet operation. The interchangeable cartridge simplifies maintenance, while rotatable ports and diverse mounting/shaft options bring flexible installation.
It fits medium-to-heavy load hydraulic equipment, including die-casting machines, hydraulic presses and large injection molding machinery for stable high-pressure industrial hydraulic systems.
Floating wear plates
Auto clearance compensation maintains over 90% volumetric efficiency and long service life under high pressure.
Balanced 10/12-vane design
Low flow pulsation, low noise and smooth running for stable system performance.
Replaceable cartridge kit
Fast on-site repair without removing the whole pump, cutting maintenance downtime.
Rotatable inlet/outlet ports
Flexible piping arrangement to fit limited installation space.
Multiple mountings and shaft options
Easy matching with various drive motors for flexible integration.
Max continuous pressure 210 bar
Compact structure delivers high power density to save layout space.

FAQ of 35VQ Vane Pumps
A: The continuous rated working pressure is 21 MPa (3000 PSI), peak intermittent pressure reaches 24 MPa. Multiple displacement options are available for the 35VQ model to match different flow demands of medium-duty hydraulic equipment.
A: Anti-wear petroleum-based hydraulic oil HLP32 or HLP46 is recommended. The ideal operating viscosity range is 17–37 cSt at 40–55°C working temperature. Oil cleanliness should meet ISO 18/15 or better, and a 10-micron suction filter must be installed.
35VQ Vane Pumps are typically packaged securely to prevent damage during transit. The packaging includes:
Protective Wrapping: To safeguard the high-precision pump body and shaft from moisture and environmental damage.
Custom Cartons or Crates: Individual reinforced packaging with shock-absorbent inserts for single pumps, and sturdy wooden crates for bulk or tandem pump orders to ensure safe handling.
Documentation: Includes technical data sheets, installation guides, and quality inspection certificates.
Delivery time depends on the specific model, port configurations, and destination but typically ranges from 1 to 4 weeks from the order date.
Pumps are manufactured in compliance with international standards, ensuring high performance and reliability:
ISO 9001: Certified for quality management systems.
CE Certification: Ensures compliance with European safety, health, and environmental protection standards.
RoHS Compliance: Ensures the pump does not contain hazardous materials.
Factory Testing: Every pump is rigorously tested for performance, pressure, and leak integrity before shipping.
