Main Parameter

Working Principle of a Rotor Pump Filling Machine

 A rotor pump filling machine operates based on the principle of positive displacement metering. Through a pair of synchronized counter-rotating rotors, the machine precisely performs product suction, metering, and discharge. This technology offers high filling accuracy, excellent product compatibility, and smooth, pulse-free material transfer.

Working Process

 1.Suction Stage

As the rotors disengage at the inlet side, the pump chamber volume increases, creating negative pressure that steadily draws the product into the pump body.

2.Metering and Transfer Stage

The product is trapped within fixed-volume cavities formed between the rotors and the pump housing, then transported toward the outlet as the rotors rotate. Since the discharged volume per rotation remains constant, precise quantitative filling can be achieved by accurately controlling the rotor speed or rotation angle with a servo motor.

3.Discharge Stage

At the outlet side, the rotors re-engage, smoothly and continuously pushing the product out of the pump chamber to complete one filling cycle.

FAQ about Single Head Filling Machine

1. What Is the Working Principle of a Rotor Pump?

 A rotor pump is a type of positive displacement pump mainly composed of a pair of synchronized rotating rotors, such as lobe rotors or gear rotors. As the rotors rotate inside the pump housing, the chamber volume changes periodically to transfer liquid. The product is drawn into the pump chamber, carried to the outlet by rotor rotation, and then discharged under pressure.

This design ensures stable, pulse-free fluid transfer and allows for highly accurate flow control, making rotor pumps ideal for precision filling applications.

2. What Are the Main Components of a Single-Head Rotor Pump Filling Machine?

A single-head rotor pump filling machine mainly consists of the following components:

Rotor Pump Head

The core transfer component responsible for flow rate and filling accuracy.

Servo Motor / Drive System

Provides power and precisely controls the rotor speed for accurate filling performance.

Control System (PLC + Touchscreen)

Enables parameter setting, filling volume calibration, and one-touch switching between different container specifications.

Hopper

Stores the product material and can be equipped with heating and mixing functions when required.

Filling Nozzle

Typically features an anti-drip diving filling nozzle with a suck-back function to minimize dripping and foaming.

Machine Frame

Supports all machine components and is commonly manufactured from 304 or 316 stainless steel for durability and hygienic operation.
