Product Description
Viking 4624B Abrasive Pump
The Viking 4624B Abrasive Pump handles liquids that contain small, hard and abrasive particles. Moreover, its internal gear design delivers consistent positive-displacement flow for paints, inks, pigments, resins and starch-based products.
Viking strengthens critical wear areas with tungsten carbide components. Therefore, the pump offers improved durability where abrasive liquid continuously passes through the pumping elements.
In addition, the current 4624B range includes compact F and FH models. Together, they provide flow capacities up to 0.34 m³/h for precise low-flow industrial duties.
Designed for Abrasive Liquids
Abrasive particles can quickly wear standard pump bushings, pins and sealing surfaces. Consequently, applications involving pigments, filled resins and industrial inks require harder materials.
The Viking 4624B uses an ultra-hard tungsten carbide idler pin and idler bushing. As a result, these important wear components resist continuous exposure to abrasive media more effectively.
Typical liquids include:
- Paints and industrial coatings
- Printing inks
- Pigments and colour concentrates
- Filled resins and polyols
- Starch and starch adhesives
- Waste oils containing fine particles
- Compatible abrasive chemical mixtures
However, users should confirm particle size, concentration, viscosity and material compatibility before selection. Therefore, the pump configuration should reflect the actual process conditions.
Key Benefits of the Viking 4624B
The Viking 4624B internal gear pump offers several practical advantages:
- Tungsten carbide idler pin
- Tungsten carbide idler bushing
- Silicon carbide mechanical-seal faces
- Rugged cast-iron casing and bracket
- Positive-displacement internal gear operation
- Flow capacities up to 1.5 GPM
- Maximum recommended pressure up to 7 bar
- Viscosity handling up to 5,500 cSt
- Temperatures up to 120°C
- Grease-lubricated bracket bushing
- Bracket bushing isolated from the pumped liquid
- Strong priming characteristics
- Standard pressure-relief valve
- Fast end-clearance adjustment
- Multiple drive arrangements
- Compact foot-mounted construction
Together, these features help reduce wear. Moreover, they support dependable operation in abrasive-liquid services.
Flow and Operating Performance
The current Viking 4624B Series includes two compact models:
- F4624B nominal flow: 0.75 GPM or 0.17 m³/h
- FH4624B nominal flow: 1.5 GPM or 0.34 m³/h
- Maximum recommended pressure: 100 PSI or 7 bar
- Viscosity range: 3.5 to 5,500 cSt
- Temperature range: -15°C to 120°C
- Maximum rated speed: 870 rpm
- Standard port size: ½-inch NPT
However, actual performance depends on liquid viscosity, abrasive concentration, speed and system pressure. Therefore, users should confirm the complete duty conditions before ordering.
In addition, higher particle concentrations may increase component wear. Consequently, users should review operating speed and maintenance intervals carefully.
Abrasion-Resistant Wear Components
Tungsten Carbide Pin and Bushing
The idler pin and bushing operate close to the pumped liquid. Therefore, Viking uses tungsten carbide to minimise wear in this critical area.
The hard material helps maintain internal alignment and clearances. Consequently, it can support longer operating life than standard materials in abrasive service.
Moreover, stable internal clearances help preserve pump efficiency. As a result, the pump can maintain more consistent output over time.
Silicon Carbide Mechanical Seal
The standard mechanical seal uses silicon carbide against silicon carbide faces. Therefore, these hard surfaces resist abrasive wear and help maintain effective shaft sealing.
Moreover, the behind-the-rotor seal position supports controlled flushing around the seal area. However, the compact F and FH models do not use the external flush line fitted to some larger abrasive-series pumps.
Protected Bracket Bushing
The grease-lubricated bracket bushing does not contact the pumped liquid. As a result, abrasive particles cannot directly attack this component.
A lip seal retains the grease inside the bracket. In addition, a relief fitting helps prevent damage from excessive lubrication.
Therefore, maintenance teams can re-grease the bracket while keeping the bushing protected from the process liquid. Consequently, the design can reduce premature wear.
Reliable Internal Gear Operation
The rotor and idler gears create expanding spaces near the inlet. As a result, these spaces draw liquid into the casing.
The gears then carry the liquid around the crescent-shaped divider. Finally, they mesh near the outlet and push the liquid into the discharge line.
Consequently, the pump produces steady positive-displacement flow across a broad viscosity range. Moreover, the internal gear design supports reliable low-flow transfer.
Drive and Installation Options
Available drive arrangements include:
- Direct-mounted drive
- Purchased gear-reducer drive
- V-belt drive
The rigid foot-mounted cast-iron bracket helps maintain alignment. Moreover, the rotatable bearing housing allows straightforward end-clearance adjustment for wear or viscosity changes.
A standard pressure-relief valve protects the pump from excessive discharge pressure. However, the system may still require an external relief path based on the installation design.
Therefore, users should review the complete piping and protection arrangement before commissioning.
