Viking LVP Series Stainless Steel Vane Pump

Vane pumps are used for liquid transfer applications ranging from chemicals to liquefied gases. Vanes extend from slots in the rotor, sweeping liquid through a cam shaped cavity. The vanes provide very low slip and high volumetric efficiency for lower total cost of ownership

Viking Advantages

• Advanced Durability
  Viking's LVP series vane pump sets the benchmark for durability with its standard, stainless steel casing surface-hardened to 62 Rockwell C maximizing casing and vane life. Its hard chrome oxide coated shaft turns in a hard silicon carbide sleeve bearing, providing industry leading pressure capabilities to 14 bar. The LVP pump's self-adjusting, PEEK plastic vanes and push rods provide superior vacuum capabilities
  
  
• Ease of Installation
  Pump installation has never been easier. The LVP series' DIN or ANSI standard porting simplifies connection to local standard systems, and eliminates adapter leak points. To protect the pump from over pressure, a top mounted, adjustable pressure relief valve is standard. For those applications utilizing local or remote monitoring systems, Viking's LVP series provides standard gauge ports. A rotatable casing with motor mount option, on two smallest models, permits vertical or horizontal porting. With motor speed operation up to 23 m3/hr @ 50Hz, Viking has eliminated a speed reducer and one shaft alignment, a coupling and guard to simplify installation, reducing system costs
  
  
• Application Flexibility
  Viking's LVP series' delivers broad chemical compatibility with its advanced durability features and higher pressure capabilities (14 bar), on even the thinnest liquids, enabling the pump to be an ideal fit for multiple liquids and applications. Its self-priming, short-term dry-run-capability and bi-directional pumping design is ideal for loading/unloading, or line stripping operations. The LVP series delivers non-pulsing, low shear flow with superior vacuum capability and volumetric efficiency to deliver the same capacity on thin liquids as a stainless steel gear or screw pump, using less energy
  
  
• Lower cost of Ownership
  The LVP series' easy to pipe, straight through porting design with raised face IEC or NEMA flanges, elastomeric O ring seals on the head, relief valve, and seal gland provide superior sealing reliability. The LVP series is also built with fewer parts, minimizing maintenance. Commonality of this series' parts reduces overall parts inventory. For example, the interchangeable discs on the front and back side of the rotor can be reversed for twice the life. In 20 minutes, a vane replacement service can be completed without removing the pump from its system, reducing maintenance time and life cycle costs. Designed for use with more than 200 thin liquids, the LVP series has tailored sealing solutions available for virtually every liquid and application to minimize leaks, for a lower total cost of ownership

Applications

• Corrosive, Thin Liquids - Acids & Alkalis, Alcohols & Solvents, Aqueous Solutions
• Flammable Liquids - Monomers, Hexane, Pentane, Refined Fuels
• Higher Pressures - Reactor Vessel Ingredient Metering, Suction Lift Applications

Pump Benefits

Advanced Durability
Hardened Casing - 62 Rockwell C surfaced hardened stainless steel casing. Extends casing and vane life, lowering life cycle costs

Hard Sleeve Bearing - Hard silicon carbide sleeve bearing, standard. Extends pressure capability, minimizes wear and lowers life cycle costs

Hard Shaft - Hard chrome oxide coated shaft. Contributes to industry leading pressure capabilities of 14 bar and extends pump life, lowering life cycle costs

Easy Installation
Gauge Ports Standard - gauge ports standard for easy application of gauges or transducers. Simplifies installation of local or remote monitoring systems

Relief Valve Standard - Top mounted, adjustable pressure releif valve standard. Eliminates cost of return-to-tank system, protects pump from over pressure from day one and beyond

Rotatable Casing - Rotatable casing with motor mount option on two smallest models (to 9m3/hr). Permits horizontal or vertical porting for easier installation

Application Flexibility
Superior Vacuum Capability and Volumetric Efficiency - Pump design provides superior vacuum capability and volumetric efficiency to deliver the same capacity on thin liquids as a stainless steel gear or screw pump, using less energy. Provides application flexibility and reduces life cycle cost

Bi-directional Pump Design - Bi-directional pumping design eliminates cost of second pump, piping and valving needed for loading/unloading or line stripping. Provides application flexibility and reduces system costs.

Broad Chemical Compatibility - Combination of hardened 316 stainless steel casing, PEEK vanes and push rods, and carbon construction provides broad chemical compatibility. Enhances application flexibility

Short Term Dry Run Capable - High efficiency pump with self priming, short term dry-run capabilities that handles entrained gases. Provides non-pulsing, low shear flow

Lower Cost of Ownership
20 Minute Maintenance - LVP Series' vane replacement is a 20 minute service item and not require rotor and shaft removal or detachment of pump from system. Reduces schedule downtime and lowers cost of ownership

Parts Commonality - Better design with fewer parts reduces maintenance and commonality of many parts between frame sizes reduces parts stocking needs. Provides better parts availability and lower cost of ownership

Interchangeable Discs - Interchangeable disks may be reversed instead of replaced when worn. Double useful life of parts, for reduced life cycle cost
