									LVP Series Stainless Steel Vane Pumps
  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
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
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
Efficiency

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

                 • Push rods between
                   opposite vanes
                   initiate vane
                   extension
Vane Extension

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

                 • Centrifugal force
                   and gravity also
                   contribute to vane
                   actuation
 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)
 LVP Series Overview

  to 160 GPM (36 M3/hr) maximum

  coupled. Frames 2 & 3 foot mount only.

   • ANSI-compatible raised-face flanges, inch-
     standard shaft seal, NEMA motor mount
   • DIN-compatible raised-face flanges, metric-
     standard shaft seal, IEC motor mount

     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.

   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.
   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.
The Viking Advantage – Maintenance

Easy disassembly and reassembly
No shimming or setting end clearances!
  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.
  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.
  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.
  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.
   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.
      The Viking Advantage – Installation
Motor-speed
operation on first

 Benefit: Eliminate reducer, one set of couplings, one shaft guard, and
 one shaft alignment. Reduces installation cost and space required.
      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.
   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.
   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.
  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.
   The Viking Advantage – Application
Seal chamber accepts many component and cartridge-style seals




Elastomer bellows single com-   O-ring Pusher single com-       Teflon® wedge single com-
ponent seal (Type 52 or 2100)   ponent seal (Type 8-1 or 58U)   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.

Twenty-Minute Maintenance




1. Lock out motor, remove drain plug and drain pump
2. Remove head capscrews and head
3. Remove disc
4. Replace vanes one by one in top slot (rounded end toward
   casing, grooves facing suction port)
5. Reassemble
  Viking Value

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

      Benefit: Viking LVP has less than half of competitor’s slip. Can allow
      a smaller pump to be used in some cases.
   Conclusion

Viking’s LVP Series Vane Pumps are your best value
   because:
less wear – Viking’s casing hardened to 62 Rockwell C vs.
   competitor’s soft 316SS. Viking’s silicon carbide bushings vs.
   competitor’s carbon graphite.
higher pressure – Viking’s 200 PSI (14 Bar) vs. competitors’ 125
   PSI (8.5 Bar)
more flexibility – Viking’s choice of motor mount or foot mount
   vs. competitor’s foot mount only
easier maintenance –Viking: fewer parts, simple disassembly/
   reassembly for fast, easy, economical repair, vs. competitor’s
   number one customer complaint: maintenance
lower life cycle cost – Viking’s reduced wear for less downtime
   and fewer replacement parts, higher volumetric efficiency.
