LVP Series Stainless Steel Vane PumpsLVP Series Stainless Steel Vane Pumps

• 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

The LVP Series…

• 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

Rotary Vane Principle

• Vanes ride on liquid film against casing.

• Carbon discs minimize slip around ends of rotor

• Less slip = higher efficiency, higher pressure capability

Efficiency

• 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 Extension

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)

• Three frames, two displacements per frame, up to 160 GPM (36 M3/hr) maximum

• Pressures to 200 PSI (14 Bar)

• 316 Stainless steel construction

• Frame 1 (Size 01 & 02) foot mount or close-coupled. Frames 2 & 3 foot mount only.

• Choice of U.S. standard (inch) or metric design

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

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

Casing Surface Hardened to 62 Rockwell C!

Benefit: Hardened casing surface is smooth longer, with less scoring, for less vane wear. Reduces maintenance & life cycle cost.

Carbon-reinforced PEEK® Vanes for high strength and low friction

The Viking Advantage – Durability

With a non-hardened 316SS casing, SS particles embed in vanes, and accelerate wear on both vanes and casing.

The Viking Advantage – Durability

Chrome Oxide Shaft Coatings

Benefit: Longer shaft and bushing life, especially if abrasives or contaminants present. Reduces maintenance & life cycle cost.

Silicon Carbide Bushings

Carbon bushings work well at low pressures, but above 125 psi / 8 bar, they can wear rapidly!

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.

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 – Maintenance

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.

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 – Installation

Reversible direction of rotation allows one pump to be used for tank loading and unloading, or line stripping.

Benefit: More flexibility. Eliminates cost of a second pump, piping and valving.

The Viking Advantage – Application

Note: Always provide pressure relief when reversed. For permanent reverse operation, change internal flow path and relief valve direction.

Seal chamber accepts many component and cartridge-style seals

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.

The Viking Advantage – Application

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)

Viking Value

Comparison to Major Competitor

Issue Viking LVP Competitor

Bushing Wear

Standard SiC bushings resist wear

Carbon graphite bushings can wear rapidly, adversely affecting vane and mechanical seal life

Vane Wear Coefficient of friction for PEEK vane material is approximately ¼ that of PPS (Ryton) material. PEEK has broader chemical resistance and 50% greater mechanical strength

PPS material is not as good for thin, non-lubricating liquids as PEEK and is not as strong as PEEK

When vanes wear to the point that they slip out of the slot

Composite 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.

Comparison to Major Competitor

Issue Viking LVP Competitor

Casing Wear

Standard surface hardened casing (62 Rc) resists wear (patent applied for)

Stainless casing material is soft and can wear rapidly

Leakage Has one-piece casing, with no seal to leak, better shaft / mechanical seal alignment

Two-piece casing design with O-ring seal, creating potential leak point and an extra point of run-out.

Pressure Capability

200 PSI (14 Bar) for broader application

125 PSI (8 Bar)

Shaft Alignment

Motor mount adaptor available on Size 01 and 02 for NEMA C or IEC B14 flanged motors eliminating alignment concerns

Not available

Better volumetric efficiency

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

Viking LVP

Competitor

Comparison to Major Competitor

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.
