What is a Blade Oil Pump?

Blade Oil Pump is a high-efficiency positive displacement pump, mainly used to transport hydraulic oil, lubricating oil, and other low-to-medium viscosity liquids. It serves as a core component in hydraulic and lubrication systems of precision mechanical equipment.

Key Advantages:

· Compact structure, stable operation, low noise

· High volumetric efficiency (90–94%)

· Compliant with ISO 10438-3:2022 and ISO 9001 standards

· Widely applied in precision machine tools, automation equipment, automotive hydraulic systems, injection molding machinery, and new energy vehicle hybrid systems

Working Principle

Blade Oil Pump operates based on the periodic volume change of the sealed cavity, formed by the rotor, blades, and stator.

· The eccentric rotor rotates, and the blades stretch radially under centrifugal force and pressure oil, closely fitting the stator inner surface.

· As the cavity expands at the suction port, negative pressure draws oil into the cavity.

· When moving to the discharge port, the cavity volume decreases, squeezing oil to form stable pressure and flow.

Our factory optimizes blade shape and stator curve design, and uses high-precision grinding to reduce blade wear and improve sealing performance. Our technical team also provides guidance for purchasers to make informed procurement decisions.

Core Structure

Blade Oil Pump’s key components include:

· Rotor: High-strength alloy steel (40Cr), carburized and quenched for wear resistance

· Blades: High-carbon, high-chromium tool steel (Cr12MoV), precision-ground for flexible stretching

· Stator: Eccentric circular or double-arc inner surface (single or double-acting type)

· Valve Plate: Separates suction and discharge, prevents backflow

· Pump Body & Sealing Components 

Factory Precision: Single blade fit gap: 0.015–0.025mm We provide spare part supply and component parameter reports for long-term procurement cooperation.
