When standard progressive cavity pumps are not enough — when your application demands higher discharge pressure for pipeline transfer, grout injection, chemical dosing, or viscous fluid boosting — Ropman Engineering Corporation’s high pressure progressive cavity pumps (HP PC pumps) deliver up to 36 bar discharge pressure without compromising on flow consistency or fluid integrity.
Manufactured at Ropman’s ISO 9001:2008 certified facility in Meerut, Uttar Pradesh, India, our high pressure PC pumps are designed for industries where pressure is critical but gentle, non-pulsating flow is equally important.
What Is a High Pressure Progressive Cavity Pump?
A high pressure progressive cavity pump is a multi-stage progressive cavity pump where multiple rotor-stator stages are arranged in series within a single unit. Each additional stage multiplies the pressure capability:
- 1-stage: Up to 6–12 bar
- 2-stage: Up to 24 bar
- 3-stage: Up to 36 bar
The rotor-stator principle remains the same — gentle progressing cavities move fluid from inlet to outlet — but with greater discharge pressure capability, enabling use in high-resistance pipelines, injection systems, and filtration systems.

Key Applications of High Pressure PC Pumps
1. Grout Injection & Construction
High pressure PC pumps are ideal for cement grout injection in civil engineering, tunnel lining, foundation grouting, and pre-stressing applications. The ability to handle thick, abrasive cement slurry at high pressure makes them indispensable on construction sites.
2. Chemical Injection Systems
In oil & gas, water treatment, and chemical processing, precise chemical dosing at high pressure is critical. HP PC pumps provide accurate, metered injection of scale inhibitors, biocides, corrosion inhibitors, and coagulants.
3. Industrial Filtration & Dewatering
High pressure PC pumps are used to feed filter presses for sludge dewatering, pressing cake formation, and solid-liquid separation in wastewater treatment and mining.
4. Pipeline Transfer of Viscous Fluids
Thick materials like molasses, spent wash, adhesives, and resins require high discharge pressure to overcome pipe friction losses over long distances. HP PC pumps handle this efficiently.
5. Spray Systems
Where fine misting or spray atomization is needed with viscous materials, high pressure PC pumps provide the necessary pressure without degrading fluid quality.
Technical Advantages of High Pressure PC Pumps
- Multi-stage design multiplies pressure without increasing pump size disproportionately
- Non-pulsating flow even at high pressure — critical for filter press and injection applications
- Handles viscous fluids that high-pressure centrifugal pumps cannot
- Gentle pumping action prevents damage to shear-sensitive materials under pressure
- Variable speed control (VFD) for precise pressure and flow regulation
- Reverse operation possible — useful for pipeline cleaning
