NYP High viscosity fluids transfer pump rotor pump

A heavy-duty rotor pump engineered for reliable transfer of high-viscosity and heat-sensitive fluids. The design uses an inner and outer rotor (positive-displacement), delivering smooth, pulse-free flow with low vibration and noise. It performs linearly with speed so flow is easily regulated by changing pump rpm.

Key specifications

• Operating temperature range: -10 °C to 150 °C
• Viscosity range: 1.0 cSt up to 6,000,000 cSt
• Pump type: rotary positive-displacement (inner/outer rotor)
• Construction highlights: rotor set, shaft, pump body, cover, bracket, seals and bearings

Performance advantages

• Smooth, non-pulsating delivery ideal for metering and gentle handling of viscous materials
• Low vibration and noise for stable operation in production environments
• Linear speed-to-flow relationship for straightforward capacity control
• Mechanical shaft sealing at the shaft end; magnetic coupling option for hermetic, leak-free operation
• Bi-directional pumping capability
• Back-pull-out design for fast maintenance and service

Materials, sealing and magnetic coupling

• Standard sliding bearing materials: cast iron, bronze (copper-based), graphite, tungsten carbide — selectable to match application wear and chemical compatibility
• Standard magnet material: NdFeB; optional SmCo magnets for high-temperature service up to 250 °C
• Fully enclosed magnetic coupling cavity protects external magnet from moisture and process exposure; ideal for outdoor installation or aggressive environments

Thermal and protective options

• Optional external heating jackets for pump cover and magnetic shielding sleeve to maintain product temperature and viscosity
• Integrated internal cooling/circulation system available — reduces the need for external cooling
• Internal and external cover protection features to extend service life in demanding installations

Operational benefits

• Dynamic axial balance system reduces axial load, lowers power consumption and extends bearing life
• Standard flange connections; pump head-only supply available for integration into custom skids or systems
• Designed for continuous industrial use across harsh media and varied temperatures

Typical applications and fluids

• Industries: petroleum, chemical, coatings, grease & lubricants, pharmaceuticals, dyes, and food processing
• Process fluids: organic and fatty acids, alkaline solutions, caustic salts, polymers, soaps and shampoos, animal and vegetable fats, chocolate and other specialty viscous fluids

Customization and serviceability

• Multiple material and sealing options to match chemical compatibility and temperature requirements
• Magnetic coupling, heating jackets and bearing materials can be specified to meet process needs
• Real back-pull design and modular components simplify maintenance and reduce downtime

This rotor pump is suitable for plants and OEMs requiring a rugged, configurable solution for metering and transferring very high-viscosity fluids under controlled temperature conditions.
