CBN / CBT Spiral Gear Screw Pump – Reliable Industrial Fluid Transfer

The CBN/CBT Gear Pump (also known as a Spiral Gear Pump or Screw Pump) is a precision-engineered positive-displacement pump designed for smooth, efficient, and low-pulsation fluid transfer across a wide range of industrial applications. Whether you're handling hydraulic oil, lubricants, fuel, or viscous fluids, this gear pump delivers consistent performance and long service life.

Made in Mainland China.

Key Features

Positive Displacement Design: Delivers a steady, near-pulsation-free flow — ideal for applications requiring consistent pressure and volume output.
Spiral Gear (Screw) Technology: Helical gear teeth mesh smoothly to minimize noise, vibration, and wear during operation.
CBN / CBT Configuration: Available in both CBN and CBT variants to suit different flow direction, port, and mounting requirements.
Compact & Robust Construction: Heavy-duty housing built to withstand demanding industrial environments.
Wide Fluid Compatibility: Suitable for hydraulic oils, gear oils, lubricating oils, diesel fuel, and other medium-to-high viscosity fluids.
Non-Electrified Operation: Mechanically driven — integrates with existing power take-off (PTO) or motor-driven systems without additional electrical components.
Precise Fluid Metering: Gear-positive displacement ensures accurate volume delivery per revolution, useful for metering and dosing systems.

Typical Applications

Hydraulic power units and systems
Industrial lubrication circuits
Fuel transfer and injection systems
Machine tool coolant and oil circulation
Agricultural and construction equipment hydraulics
Chemical processing fluid handling (non-corrosive media)

Why Choose a Spiral Gear Pump?

Unlike standard external gear pumps, spiral (helical) gear pumps offer quieter operation, reduced vibration, and longer component lifespan due to the progressive engagement of gear teeth. This makes them a preferred choice in noise-sensitive or precision-critical industrial settings. For more background on positive-displacement pump principles and safety, refer to the OSHA Hydraulic Machinery Safety Guidelines.

Frequently Asked Questions

Q: What is the difference between a CBN and CBT gear pump?

A: CBN and CBT designations refer to the rotation direction and port configuration of the gear pump. CBN pumps are typically configured for one direction of rotation, while CBT pumps accommodate the opposite rotation or a different port layout. Always verify your system's requirements — shaft rotation direction, inlet/outlet port positions — before selecting the appropriate model for your application.

Q: What types of fluids can this spiral gear pump handle?

A: This CBN/CBT spiral gear screw pump is compatible with a wide range of medium-to-high viscosity fluids including hydraulic oil, gear oil, lubricating oil, and diesel fuel. It is not recommended for highly corrosive or abrasive fluids unless specifically rated for such media. Always consult the pump's rated specifications before use.

Q: Is this pump self-priming?

A: Gear pumps of this type are generally capable of limited self-priming at low lift heights, making them suitable for most standard installation configurations. For best performance and longevity, ensure the pump is installed below or at the fluid source level whenever possible to minimize dry-running risk during initial startup.

Q: How is this pump driven — does it require a motor or electric power?

A: This is a non-electrified pump, meaning it requires an external mechanical drive source such as a power take-off (PTO) shaft, a hydraulic motor, or a standard electric motor mounted separately. The pump itself does not include an integrated motor or electrical components.
