Technical Information

Progressive Cavity Pump Introduction

A progressive cavity pump operates via a helical rotor rotating inside a double-helix stator, creating sealed cavities that move fluid axially with low pulsation and high efficiency.

Configuration Options

Available in horizontal, vertical, trolley, and skid-mounted configurations with various drive options including belt, direct, and variable frequency drives.

Shaft Seal Selection

Choose from mechanical seals, packing glands, or sealless designs based on media, pressure, and environmental requirements.

Rotor and Stator Selection

Rotors in hardened steel or coated alloys; stators in NBR, EPDM, or FKM elastomers for compatibility with diverse media.
