  1. LVP Series Stainless Steel Vane Pumps

  2. The LVP Series… • is an industrial duty vane pump designed and built for the process industries, not an LPG pump adapted for industrial use • is far more durable than other stainless steel vane pumps because of its hardened casing and hard components in critical wear areas • is capable of higher pressures (200 PSI/14 Bar) than competitive vane or gear pumps on thin liquids • is more robust than other vane pumps, which means it is not dimensionally interchangeable

  3. Rotary Vane Principle • Rotor turns in casing with cam profile • Cavity forms at suction side to draw liquid in • Vanes move liquid through casing • Cavity decreases at discharge to force liquid out

  4. Rotary Vane Principle • Rotor turns in casing with cam profile • Cavity forms at suction side to draw liquid in • Vanes move liquid through casing • Cavity decreases at discharge to force liquid out

  5. Efficiency • Vanes ride on liquid film against casing. • Carbon discs minimize slip around ends of rotor • Less slip = higher efficiency, higher pressure capability

  6. Vane Extension • Push rods between opposite vanes initiate vane extension

  7. Vane Extension • Liquid from high pressure side flows through vane slots to help drive vane extension.

  8. Vane Extension • Centrifugal force and gravity also contribute to vane actuation

  9. Vane vs. Gear Pump Efficiency • Gear pumps gradually lose volumetric efficiency over time • Vanes maintain efficiency by self-adjusting (extending out) to compensate for wear • Replace vanes when performance begins to drop (recommend Power Load Monitor)

  10.

  13. Specifications – 60 Hz Speeds

  14. Materials of Construction

  15. Seals – “U” (inch standard) pumps CG/SiC seal face materials are standard on all seals for better seal life and broad chemical compatibility

  16. Motor Mount • Sizes 01 and 02 offer foot or motor mount, all other sizes foot mount only. • “U” models (inch standard) couple to NEMA C-face motors: 56C, 143/145TC, 182/184TC • “M” models (metric standard) couple to IEC B14 Flange motors: 90, 100, 112, 132

  17. LVP Limitations • Temperature • Standard pump rated @ -15° to 275°F (-26° to 135°C). Limiting factor: bushing interference fit • Up to 500°F(260°C) using optional carbon graphite bushings & vanes, Kalrez® seals, but pressure limited to 125 PSI (8 Bar) when using optional carbon graphite bushings. • -60°F(-51°C) with EPR seals. • Viscosity - Consult factory for viscosities over 2300 SSU (500 cSt.) • Drive Equipment – Side loads (belt or chain drives) not allowable

  18. The Viking Advantage – Durability Casing Surface Hardened to 62 Rockwell C! Carbon-reinforced PEEK® Vanes for high strength and low friction With a non-hardened 316SS casing, SS particles embed in vanes, and accelerate wear on both vanes and casing. Benefit: Hardened casing surface is smooth longer, with less scoring, for less vane wear. Reduces maintenance & life cycle cost.

  19. The Viking Advantage – Durability Silicon Carbide Bushings Chrome Oxide Shaft Coatings Carbon bushings work well at low pressures, but above 125 psi / 8 bar, they can wear rapidly! Benefit: Longer shaft and bushing life, especially if abrasives or contaminants present. Reduces maintenance & life cycle cost.

  20. The Viking Advantage – Maintenance Easy disassembly and reassembly No shimming or setting end clearances!

  21. The Viking Advantage – Maintenance Easy access back pull-out seal Benefit: Simple seal replacement. No thrust bearings to remove for seal access. No thrust bearing lubrication. Faster maintenance for lower cost.

  22. The Viking Advantage – Maintenance Carbon discs for anti-slip and thrust control are reversible. When worn, switch them instead of replacing them. Benefit: Doubles usable life of discs. No shimming or end clearance adjustment! Faster maintenance for lower cost.

  23. The Viking Advantage – Maintenance Top-mounted pressure relief valve (not shown) and casing drain for complete drainability Benefit: All liquid can be drained from pump before maintenance. Improved safety, less chemical cleanup.

  24. The Viking Advantage – Maintenance For users with multiple pump sizes, the rotor/ shaft, vanes & seals are common within a frame. Frame 2&3 shafts same diameter for common seals. Benefit: Fewer parts to stock. Lower inventory costs.

  25. The Viking Advantage – Maintenance Thin-liquid design uses O-ring seals (not gaskets or Teflon seal rings), and Raised Face flanges standard Benefit: Prevents leakage even with very thin liquids. Improves safety and helps prevent cleanup costs.

  26. The Viking Advantage – Installation Motor-speed operation on first 3 sizes (60 Hz) and 4 sizes (50 Hz) can eliminate speed reducer or gear motor Benefit: Eliminate reducer, one set of couplings, one shaft guard, and one shaft alignment. Reduces installation cost and space required.

  27. The Viking Advantage – Installation Opposite ports, with either ANSI B16.5-compatible 150# class raised face flanges, or DIN 2501- compatible PN 16/25/40 raised face flanges for easy in-line piping. Inch- or metric- standard shafts, seals and motor-mount. Benefit: Easy to install according to local standards worldwide. Eliminates adapters, allows local coupling and seal sourcing. Reduces installation cost and ensures local seal availability.

  28. The Viking Advantage – Installation Adjustable pressure relief valves standard. Available without valve (with cover plate) or with return-to-tank valve. Benefit: Protects pump from system upsets, eliminates cost of external relief valve and piping. Reduces installation cost.

  29. The Viking Advantage – Installation Gauge ports standard. Benefit: Easy installation of vacuum or pressure gauges or transducers for condition monitoring. Reduces cost of installing monitoring equipment.

  30. The Viking Advantage – Application Reversible direction of rotation allows one pump to be used for tank loading and unloading, or line stripping. Note: Always provide pressure relief when reversed. For permanent reverse operation, change internal flow path and relief valve direction. Benefit: More flexibility. Eliminates cost of a second pump, piping and valving.

  31. The Viking Advantage – Application Seal chamber accepts many component and cartridge-style seals Elastomer bellows single com-ponent seal (Type 52 or 2100) O-ring Pusher single com-ponent seal (Type 8-1 or 58U) Teflon® wedge single com-ponent seal (Type 9 or 59U) Single cartridge seal Double cartridge seal Triple Lip cartridge seal Benefit: Sealing options for almost any liquid or application, with local seal availability from user’s preferred vendors. Minimizes leakage,reduces seal maintenance and inventory costs.

  32. Internal Flow – Clockwise Rotation Internal flow cools and lubricates bushings and shaft seal

  33. Disc Placement – Clockwise Rotation Grooved sides face motor Drain groove at bottom Both discs always face same direction! Align hole with open internal flow channels

  34. Internal Flow – Counterclockwise Rotation For permanent reversal, reverse location of suckback set screws, reverse direction of discs and relief valve (requires diassembly of pump)

  35. Internal Flow – Counterclockwise Rotation Smooth sides face motor Both discs always face same direction! Align hole with open internal flow channels

  36. Twenty-Minute Maintenance • Lock out motor, remove drain plug and drain pump • Remove head capscrews and head • Remove disc • Replace vanes one by one in top slot (rounded end toward casing, grooves facing suction port) • Reassemble

  37. Viking Value Motor mount option on Frame 1 pumps eliminates coupling guard and shaft alignment, and allows casing to be rotated to vertical orientation.
