NVP series Vane pumps: A safe and reliable choice for efficient transportation of media with high saturated vapor pressure
The NVP series vane pumps come in two specifications: NVP and NVPG. They are specially designed for the efficient and safe transportation of industrial liquids with high saturated vapor pressure and various petrochemical products. This series of pumps, with its outstanding seal selectivity, excellent material adaptability and rich functional configuration, has become an ideal solution for high-demand fluid transportation scenarios in fields such as chemical engineering, petroleum and energy.
Core features and performance advantages
Reliable dry running resistance: Standard equipped with anti-dry running sliding bearings, effectively reducing the risk of equipment damage caused by unexpected dry running, and enhancing operational stability and service life.
Comprehensive sealing options: Depending on the medium characteristics and working conditions, single-end face mechanical seals, double-end face mechanical seals, lip seals or packing seals can be selected. For flammable, toxic or high-risk media, zero-leakage magnetic drive solutions are provided, greatly enhancing safety.
Flexible temperature control configuration: Supports the selection of insulation jackets for front and rear end covers to meet the process requirements of insulation or cooling, ensuring the stability of the medium transportation temperature.
Built-in safety protection: All pump types are equipped with a standard pump body relief valve, effectively preventing system overpressure and ensuring the safety of equipment and pipelines.
Multiple material options are available to adapt to complex media
The NVP series offers a wide range of material options to meet different corrosion and purity requirements
Standard materials: 316L stainless steel, GGG40 ductile iron
Special materials: 2507SS super duplex stainless steel, cast copper, etc
Users can flexibly select materials based on the characteristics of the medium to achieve the optimal balance of corrosion resistance, wear resistance and economy.
Typical application scenarios
Petrochemical industry: Transportation of high vapor pressure media such as benzene, propylene, and light hydrocarbons
Chemical process: Transfer and circulation of solvents, additives, and liquid chemical raw materials
Energy sector: fuel transportation, liquefied gas treatment, etc
Why choose the NVP series vane pump?
The NVP series is not only renowned for its high reliability, multiple sealing combinations and flexible structural design, but also offers a comprehensive range of material and functional options to help customers address diverse and complex working conditions. It is an excellent choice for achieving safe transportation, reducing maintenance costs and improving operational efficiency.
