2 The LVP Series…is an industrial duty vane pump designed and built for the process industries, not an LPG pump adapted for industrial useis far more durable than other stainless steel vane pumps because of its hardened casing and hard components in critical wear areasis capable of higher pressures (200 PSI/14 Bar) than competitive vane or gear pumps on thin liquidsis more robust than other vane pumps, which means it is not dimensionally interchangeableIt fills Viking’s performance gap on thin, corrosive liquids, giving us new applications and customers who required pressures that Viking could not deliver in the past.By ignoring this gap, we have allowed Blackmer to take too much of our business in thin liquid applications.Offers higher performance and is more durable than other vane pumps, with higher pressures and longer lasting casing, bushings, shafts and vanes.It’s a thin liquids pump, designed for 28 to 2,500 SSU only. The LVP is the best solution for thin liquids, but it is not applicable over 2500 SSU. That’s where gear pumps shine.It offers a lower cost alternative to SS gear pumps, for those applications where you need a little bit lower price to get the job.
3 Rotary Vane Principle Rotor turns in casing with cam profile Cavity forms at suction side to draw liquid inVanes move liquid through casingCavity 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 inVanes move liquid through casingCavity decreases at discharge to force liquid out
5 Efficiency Vanes ride on liquid film against casing. Carbon discs minimize slip around ends of rotorLess slip = higher efficiency, higher pressure capability
6 Vane ExtensionPush rods between opposite vanes initiate vane extension
7 Vane ExtensionLiquid from high pressure side flows through vane slots to help drive vane extension.
8 Vane ExtensionCentrifugal force and gravity also contribute to vane actuation
9 Vane vs. Gear Pump Efficiency Gear pumps gradually lose volumetric efficiency over timeVanes maintain efficiency by self-adjusting (extending out) to compensate for wearReplace vanes when performance begins to drop (recommend Power Load Monitor)You can see that vane pumps maintain maximum efficiency longer than gear pumps because the end of the vane is designed to contact the casing, as a sacrificial part. Vanes can wear up to 50% of their length before losing efficiency, but when that efficiency drops, you have to replace the vanes.In a gear pump, the gear tips do not contact the casing, so they lose efficiency very gradually and consistently.You may replace the vanes in a vane pump several times before you would have to replace the gears in a gear pump, but the relative cost of replacing vanes is lower than replacing gears.Since the vane wear is inherent in the design, a good pump should make it easy to replace vanes. Viking does.

21 The Viking Advantage – Durability Casing Surface Hardened to 62 Rockwell C!Carbon-reinforced PEEK® Vanes for high strength and low frictionWith a non-hardened 316SS casing, SS particles embed in vanes, and accelerate wear on both vanes and casing.The casing is hardened using low temperature nitriding, just like we do our stainless gear pump rotors.This reduces wear on the casing, which was a major complaint among Blackmer users.It reduces the chance of pickup if the rotor does contact the casing.The hardening process only goes a few thousandths of an inch deep, so extended use on abrasive liquids will penetrated the hardening and allow wear.For mildly abrasive liquids, it will last much longer than an unhardened stainless steel pump.What if Blackmer hardens their casing? They can, a little bit, but not to the hardness that Viking achieves, because their investment cast pump has much less metal, which makes it susceptible to warping during the ion-nitriding process. This distortion leads to leakage and excessive vane wear.Benefit: Hardened casing surface is smooth longer, with less scoring, for less vane wear. Reduces maintenance & life cycle cost.
22 The Viking Advantage – Durability Silicon Carbide BushingsChrome Oxide Shaft CoatingsCarbon bushings work well at low pressures, but above 125 psi / 8 bar, they can wear rapidly!Test pumps at 200 PSI with carbon graphite bushings failed due to bushing wear after 100 hours. Silicon carbide exhibited zero wear after 350 hours.Benefit: Longer shaft and bushing life, especially if abrasives or contaminants present. Reduces maintenance & life cycle cost.
23 The Viking Advantage – Maintenance Easy disassembly and reassemblyNo shimming or setting end clearances!
24 The Viking Advantage – Maintenance Easy access back pull-out sealBenefit: Simple seal replacement. No thrust bearings to remove for seal access. No thrust bearing lubrication. Faster maintenance for lower cost.
25 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.
26 The Viking Advantage – Maintenance Top-mounted pressure relief valve (not shown) and casing drain for complete drainabilityBenefit: All liquid can be drained from pump before maintenance Improved safety, less chemical cleanup.
27 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.FrameSizeShaft Ø“U” (in)“M” (mm)10125022051.5380831923Benefit: Fewer parts to stock. Lower inventory costs.
28 The Viking Advantage – Maintenance Thin-liquid design uses O-ring seals (not gaskets or Teflon seal rings), and Raised Face flanges standardBenefit: Prevents leakage even with very thin liquids Improves safety and helps prevent cleanup costs.
29 The Viking Advantage – Installation Motor-speed operation on first 3 sizes (60 Hz) and 4 sizes (50 Hz) can eliminate speed reducer or gear motorSize60 Hz RPMGPM50 Hz RPMM3/hr0117502014503.602407.40511508095015081002219520125292316036Benefit: Eliminate reducer, one set of couplings, one shaft guard, and one shaft alignment. Reduces installation cost and space required.
30 The Viking Advantage – Installation Opposite ports, with either ANSI B16.5-compatible 150# class raised face flanges, or DIN 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.
31 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.
32 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.
33 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.
34 The Viking Advantage – Application Seal chamber accepts many component and cartridge-style sealsElastomer 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 sealDouble cartridge sealTriple Lip cartridge sealBenefit: 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.
35 Internal Flow – Clockwise Rotation Liquid enters the suction port, passes through the cam profile to the discharge port, where pressure increases. This causes liquid indicated by the red arrow to flow from the higher pressure discharge side to the lower pressure suction side, to provide cooling and lubrication between the bushings and shaft.Internal flow cools and lubricates bushings and shaft seal
36 Align hole with open internal flow channels Disc Placement – Clockwise RotationGrooved sides face motorThe long slot on the left side of the rotor side of the outboard (or head) disc allows fluid access to the head bushing, and the bore and slot on the right allow liquid to flow back to the suction side.On the inboard (or casing) disc the bore serves no purpose, but the short slot allows liquid back to the suction side, and the long slot allows liquid access to the bushing and seal.Discs are identical and face same direction. When worn on one side, switch locations and flip to the other side.Drain groove at bottomBoth discs always face same direction!Align hole with open internal flow channels
37 Internal Flow – Counterclockwise Rotation To permanently reverse direction of flow, reverse the location of the two setscrews and flip the direction of the discs and relief valve. This is counterclockwise flow (left hand suction).For permanent reversal, reverse location of suckback set screws, reverse direction of discs and relief valve (requires diassembly of pump)

41 Comparison to Major Competitor IssueViking LVPCompetitorBushing WearStandard SiC bushings resist wearCarbon graphite bushings can wear rapidly, adversely affecting vane and mechanical seal lifeVane WearCoefficient of friction for PEEK vane material is approximately ¼ that of PPS (Ryton) material. PEEK has broader chemical resistance and 50% greater mechanical strengthPPS material is not as good for thin, non-lubricating liquids as PEEK and is not as strong as PEEKWhen vanes wear to the point that they slip out of the slotComposite vanes and push rods minimize damage to hard casing. Replacement vanes are longer-lasting against smooth casing.Metal vane inserts and push rods score casing, cause pick-up. Replacement vanes wear quickly against rough casing.
