1 LVP Series Stainless Steel Vane Pumps

2 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…

3 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

4 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

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

6 Push rods between opposite vanes initiate vane extension Vane Extension

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

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

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)

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

21 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.

22 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!

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

24 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

25 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

26 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

27 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 FrameSizeShaft Ø U (in) M (mm)

28 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

29 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. The Viking Advantage – Installation Size 60 Hz RPM GPM 50 Hz RPM M3/hr

30 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. The Viking Advantage – Installation

31 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

32 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

33 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.

34 Seal chamber accepts many component and cartridge-style seals Benefit: Sealing options for almost any liquid or application, with local seal availability from users 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) Single cartridge sealDouble cartridge sealTriple Lip cartridge seal

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

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

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

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

39 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 Twenty-Minute Maintenance

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

41 Comparison to Major Competitor IssueViking LVPCompetitor Bushing Wear Standard SiC bushings resist wear Carbon graphite bushings can wear rapidly, adversely affecting vane and mechanical seal life Vane WearCoefficient 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.

42 Comparison to Major Competitor IssueViking LVPCompetitor Casing WearStandard surface hardened casing (62 Rc) resists wear (patent applied for) Stainless casing material is soft and can wear rapidly LeakageHas 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

43 Better volumetric efficiency Benefit: Viking LVP has less than half of competitors slip. Can allow a smaller pump to be used in some cases. Viking LVP Competitor Comparison to Major Competitor

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