The high-pressure rotary pump is a positive displacement pump specially designed for high-pressure conveying conditions. It uses a high-precision rotor meshing structure as its core power source to stably, continuously, and under high pressure deliver fluid to a designated location within a sealed cavity. Compared to traditional centrifugal pumps, screw pumps, or plunger pumps, the high-pressure rotor pump boasts higher pressure resistance, more stable flow output, and stronger wear and particle resistance. Furthermore, it is widely used in industries such as food, chemical, daily chemical, and pharmaceutical due to its excellent hygiene standards and CIP/SIP cleaning compatibility.
For materials with high viscosity, high solids content, high viscosity, easy crystallization, or requiring precise metering, high-pressure rotary pumps exhibit unique efficiency and reliability, such as:
* Chocolate syrup
* Honey, syrup
* Laundry detergent, shower gel, cream
* Petroleum thickeners, colloids, resins
* Ointments, gels, creams
* Inks, pigments, additives
* High-viscosity chemical raw materials
They can maintain stable output even under high-pressure conditions, making them a core power conveying device in many factory production lines.
Working Principle: Precise, Stable, and Pulsation-Free
The high-pressure rotary pump consists of two (or three) synchronously rotating in opposite directions impellers (rotors). The rotors maintain a small meshing clearance and are driven synchronously by a reducer and a motor. As the rotors rotate, a closed chamber is formed within the pump cavity, continuously pushing material from the inlet to the outlet.
High-Pressure Rotary Pump Structural Characteristics:
* Reinforced pump body thickness for increased pressure resistance
* High-strength rotor, better suited for high-viscosity or particulate materials
* Optimized internal clearance design to reduce wear and improve efficiency
* Reinforced mechanical seal structure to withstand higher operating pressures
* Precision-machined pump cover, pump body, and rotor for improved sealing and long-term stability
This structure enables the high-pressure rotary pump to:
✔ Pulsation-free output – more stable material flow
✔ High-pressure delivery capacity – able to withstand higher discharge pressures
✔ Low material shear – does not damage material properties
✔ Handles high-viscosity, particulate, and sensitive materials
This is why it is popular in food filling, paste conveying, and chemical additive conveying industries.
Core Advantages: Professional conveying equipment suitable for high-pressure conditions
1. Increased high-pressure conveying capacity by 30%–60%
Thanks to the reinforced pump body and high-strength rotor structure, the high-pressure rotary pump can maintain stable output at pressures up to 1.2MPa (actual pressure varies slightly depending on the model).
2. Supports high-viscosity materials (1–1,000,000 CP)
Whether it's chocolate paste, resin, ink, or gel materials, it can easily and continuously convey them without clogging, slippage, or unstable conveying.
3. Sanitary design (316L optional)
Suitable for the food, pharmaceutical, and cosmetic industries. The pump chamber features a mirror-polished finish and supports:
CIP (Clean-in-Place)
SIP (Steam-in-Place)
Quick-release design
Ensuring compliance with FDA, EHEDG, or 3A hygiene requirements.
4. Low shear force, does not damage material structure
Suitable for:
* Granular foods (fruit pulp, soy milk, large-particle jams)
* Foaming-sensitive liquids
* Dosage form-sensitive materials (pastes, emulsions)
5. Strong wear resistance and particle resistance
Rotor material options:
Stainless steel rotor
Alloy steel rotor
Rubber-coated rotor
Special reinforced polymer rotor
Suitable for applications with a solids content up to 20%.
6. Simple maintenance and short downtime
The pump body has a compact structure and internal components can be quickly disassembled and assembled. Only routine checks of seals and bearings are required for long-term stable operation, making it ideal for continuous production line operation.
Application Industries
Food Industry: Chocolate spread, peanut butter, sesame paste, honey, high-fructose corn syrup, cream, concentrated milk, ice cream base
Chemical Industry: Coatings, inks, adhesives, resins, polymers, lubricants, petrochemical additives
Pharmaceutical Industry: Ointments, gels, high-concentration raw material liquids, cream and semi-solid dosage form delivery
Cosmetic Industry: Laundry detergent, disinfectant, emulsions, face creams, fragrances, ointments
Environmental Protection Industry: Sludge transportation, wastewater dosing, chemical reagent transportation, etc.
