Product Description

  • AR1-F type is a reversible pump in which suction and discharge directions are always constant regardless of the direction of rotation of the pump.
    The main use is suitable for supplying lubrication to machine tools, industrial machines, and other general-purpose machines.

Overview of the pump

T-ROTOR describes the path followed by a point on a circular plate where it undergoes a rolling contact motion around a fixed circle without slipping. The trajectory created by the outer rolling motion of the disk, beyond its circumference, is known as an Epi-trochoid. The trajectory resulting from the inner rolling motion is referred to as a Hypo-trochoid.

The T-Rotor Pump is an internal gear pump consisting of a pair of internal and external gears manufactured based on the Trochoid Curve.

How it Works 

The T-ROTOR pump operates by creating a chamber of space. The T-ROTOR has a pair of teeth that is designed according to the Trochoid Curve principle, which undergo inward rolling motion. It is a pump that discharges.

The In-Rotor has one fewer gear tooth than the Out-Rotor and rotates eccentrically at a specific distance from the external gear.

The pump is designed to forcibly draw in and discharge fluid by maintaining constant space between the external teeth. The space is constantly large or small. The motion of the rotor is depicted in the image below.

Features of the pump

1. High suction pressure and high mechanical and volumetric efficiency.

2. Because the internal and external gears make rolling contact motion by trochoid curve, the relative speed is lower than that of the gear pump. As a result, there is reduced tooth wear and discharge pulsation.

Because the internal and external gears make rolling contact motion using the trochoid curve, the relative speed is lower than that of the gear pump. As a result, there is reduced wear to the tooth and discharge pulsations are less. 

3. Its straightforward design makes it easy to disassemble, assemble, and repair. In addition, this oil pump is smaller than other gear pumps that share a similar capacity, has a longer service life, and has more discharge per rotation.

4. Unlike gear pumps, the T-Rotor pump does not require a Cresent-Shaped Spacer. It also has various applications in areas such as lubrication, hydraulics, and transportation.

5. Since it always rotates at a single point of contact, the rotation can range from low to high speeds (300 to 3000 RPM).
