Metering and Dosing Progressive Cavity Pump

MJ Metering pump are a range of motor driven precision pumps that have a metering accuracy of ±1%. Our various metering pumps are widly used in industrial and municipal fields, such as water treatment.

Chemical metering pumps can effectively transport mediums of various viscosities with low pulsation rates. Additionally, these pumps are commonly used for metering high-viscosity media and containing-solids media .

Flow rate：Q ≤ 500 m3/h (2200 USGPM)

Pressure：P ≤ 24 bar (350 psi / 2.4 MPa)

High Precision

Metering accuracy of ±1% deviation, ideal for critical dosing applications requiring strict volumetric control.

Low Pulsation & Shear

Gentle, near-pulsation-free pumping without dampers or compensators, minimizing shear stress for shear-sensitive or high-viscosity media (e.g., chocolate, pharmaceutical slurries).

Stable Flow

Consistent flow rate unaffected by pressure fluctuations, even at very low speeds.

Compact & Miniaturized Design

Axial dimensions 1/3–1/2 shorter than conventional pumps, enabling space-saving integration in confined environments.

Versatile Material Handling

Handles abrasive slurries, high-solid-content media, and shear-sensitive substances (e.g., cosmetics, food-grade materials).

Easy Maintenance

Modular components and tool-free disassembly reduce downtime. Maintenance-free operation with low lifecycle costs.

Flexible Drive Options

Compatible with variable frequency control (VFD) and servo motors for precise speed adjustment and flow proportionality.

Multi-Industry Applicability

Ideal for food, pharmaceuticals, chemicals, and cosmetics—suited for metering, dosing, and hygienic transfer tasks.
