HEISHIN DISPENSER

Structure and Principle

High-accuracy, Metered Dispensing

Structure of Heishin Dispensers

The standard structure of Heishin Dispensers is the same as Heishin PC Pumps and features a progressing cavity pump that uses rotary positive-displacement. The central part is composed of a rotor equivalent to male threads and a stator equivalent to female threads. In the gap between the rotor and the stator, a series of independent sealed chambers called "cavities" is created.

Principle of Heishin Dispensers

When the rotor turns in the stator, a suction force that draws in high-viscosity fluids is produced, and as each new cavity is created, the cavities move toward the dispense end. Fluid drawn into the cavity is conveyed in a sealed chamber and continuously conveyed forward.

The cross-sectional area of each cavity is always constant regardless of the position of the rotor, enabling a constant flow rate that is directly proportional to the rotational speed of the rotor.

At any cross-section perpendicular to the shaft, the cross-sectional area of the cavities created by the rotor and the stator is always constant, enabling non-pulsating, metered conveyance.

Features and Advantages

Heishin Dispensers can, by working on the principles of progressing cavity pumps, perform high-accuracy dispensing.
