Progressive Cavity Pump: Applied in conveying high-viscosity fluids, high-solid-content slurries, dewatered dry materials, and fluid/gas/solid mixtures
The progressive cavity pump is specially designed for the efficient, stable and low-shear conveyance of high-viscosity fluids, high-solid-content slurries, dewatered dry materials, and fluid/gas/solid mixtures. Its unique rotor-stator meshing working principle endows it with incomparable advantages over centrifugal pumps and conventional reciprocating pumps in handling complex media, making it a reliable choice for processing challenging fluids in industries such as food, chemical engineering, environmental protection, mining, and oil and gas.
Operating Characteristics
Wide application range, capable of conveying all flowable and even non-flowable materials.
Bi-directional rotation and bi-directional conveyance available.
Stable flow and pressure with no pulsation.
Flow rate is proportional to rotational speed, suitable for metering and dosing applications.
Low operating noise and high efficiency.
Application Fields
Energy and environmental engineering, papermaking industry, petroleum industry, chemical engineering, mineral engineering, food industry
