Overview of Butterfly and Single Butterfly Curved Rotor Pumps

Butterfly rotor pumps utilize a butterfly-shaped rotor, offering advantages over conventional rotor pumps, especially in handling high-viscosity materials and those containing larger particles. They effectively transport extremely viscous substances without damage.

The single butterfly curved rotor pump, also known as the particle rotor pump, is specifically designed for materials with large particles. Its unique shape and curved design prevent particle breakage during transport, making it the preferred choice for pumping particulate-laden materials.

Applications

• Suitable for various special materials, viscous substances, mixtures with different specific gravities, corrosive materials, and materials containing large particles.

Technical Specifications and Operating Parameters

The flow rates listed in the provided table are based on water as the medium. Speed control is achieved via stepless speed variators or frequency converters, with speed ranges set according to actual working conditions. Motor power should be increased when pumping high-viscosity liquids.

Special Features and Design

• Sanitary design: All parts contacting the material are made of stainless steel meeting sanitary standards, suitable for food, beverage, pharmaceutical, and chemical industries.
• Heat preservation sleeve: Available for applications requiring temperature maintenance to prevent coagulation of materials during pumping.
• Water-cleaning mechanical seal: Prevents coagulation on the seal surface during high-viscosity material pumping, extending seal life in harsh environments.
• Minimal wear: Except for the mechanical seal, the pump has almost no wear parts. Rotors run synchronously with a gap, avoiding contact and wear, enabling operation at temperatures up to 220°C.

Main Application Characteristics

The rotor pump is a volumetric pump characterized by low speed, high output torque, and high-temperature resistance, making it ideal for pumping high-viscosity and high-temperature materials. Its unique operating principle combined with a powerful drive system ensures continuous, non-stagnant material feeding without damaging the material properties. It can handle viscosities up to 1,000,000 CP.

When pumping thin media, especially where pulse-free output is required, the rotor pump shows significant performance advantages. If viscosity decreases and leakage increases, the matched drive system can increase speed to maintain constant output flow.

Additional Product Variants

• Stuffing product feeding rotor pump (top inlet, bottom outlet)
• Movable rotor pump with mixing tank
• Sanitary feeding pump
• Thin medium feeding pump

Notes

• Flow data is based on water as the medium and may change without notice; actual product parameters prevail.
• Speed and motor power should be adjusted according to actual working conditions and material viscosity.
