Flux Barrel Hand Pump – Manual, Hand-Operated Fluid Transfer

£50.90

The Flux barrel hand pump is a durable, safe fluid transfer solution for manually dispensing smaller volumes. This reliable hand pump is designed for use in workshops, service centres, laboratories and production environments. The unit combines robust polypropylene construction with modern ergonomics, chemical-resistant seal options and an adjustable uptake tube, making it suitable for a wide range of different drums, barrels and hobbocks. This hand operated barrel pump provides controlled low-viscosity fluid transfer without the need for electricity, batteries or compressed air. Its portable, lightweight design makes it ideal for remote sites, outdoor areas or facilities seeking a low-cost, dependable dispensing method. Moreover, with a choice of chemical-resistant o-ring materials and barrel adaptors, it can be used wide range of liquids and container types.

Dispensing oils, glycol, antifreeze, coolant and transmission fluids in automotive workshops
• Transferring detergents, surfactants, degreasers and alkaline cleaners in hygiene and also maintenance operations
• Pumping AdBlue from 200-220 L drums in vehicle fleet and agricultural environments
• Chemical dosing in water treatment, laboratory and plating applications
• Decanting dilute alkalis, for instance bleach, sodium hydroxide, sodium hypochlorite
• General drum-to-container transfer in warehouses and chemical stores

Media examples for Flux barrel hand pump

Common fluids handled by the Flux barrel hand pump include:
• AdBlue
• Light mineral oils and lubricants
• Glycol, antifreeze and coolant mixes
• Mild acids (inorganic) stored in plastic drums
• Detergents, surfactants and degreasers
• Water-based solutions
• Alkalis: sodium hydroxide (low concentration), ammonia solutions
• Transmission fluids and also hydraulic oils

Note: Media compatibility depends on correct seal selection (NBR, EPDM or Viton). Always check compatibility before use.

O-rings / seal options:

• Nitrile (NBR): Suitable for oils, diesel, light hydrocarbons and additionally lubricants
• Viton (FKM): Resistant to AdBlue, antifreeze, transmission fluids, inorganic acids
• EPDM: Suitable for detergents, water-based fluids, alkalis, CIP solutions

This portable hand-operated barrel pump offers an exceptional cost-to-performance ratio and is ideal for safe dispensing of smaller volumes. It is the perfect solution when electric or battery-powered pumps are uneconomical, or when a power supply is not available.

Eliminates the need to lift and tip chemical containers, reducing manual handling and spill risk.

Key reasons to choose this model:

Chemical resistance: A choice of three seal materials for compatibility with oils, chemicals, alkalis, coolants and aqueous solutions
Low price: Ideal for dispensing smaller volumes
Proven design: Builds on decades of proven field performance, with enhanced lever action and improved valve assembly design.
Operator safety: Eliminates lifting and tipping. The anti-drip nozzle, secure bunghole connector and adjustable uptake pipe guarantee controlled dispensing with minimal risk of spillage.
Ease of use: Self-priming action and smooth, rhythmic lever operation ensure consistent flow and reduced operator fatigue.
Maintenance efficiency: The quick-access valve assembly enables fast cleaning and internal inspection, with no specialist tools required.
Universal: Fits barrels with standard 2” BSP drum openings. Range of adaptors available for plastic drums.
Compact ergonomics: Lightweight and suitable for frequent or occasional use.
Environmentally friendly: Finally, this pump can be recycled when no longer needed.

The Flux barrel hand pump operates through a lever-driven positive displacement mechanism with one-way valve assembly.

Each downward stroke creates a pressure differential that lifts the liquid through the telescopic uptake tube and into the pump chamber.

A check valve prevents backflow, ensuring that the entire chamber fills with fluid before discharge. On the upward stroke, the outlet valve opens and expels the liquid through the spout.

This process repeats with each stroke. Full priming typically occurs after 3–4 cycles, after which the delivery stabilises at approx. 300–375 ml per stroke.

The adjustable uptake tube with air tight seal ensures that suction loss is minimised by preventing air entrainment – essential for consistent volumetric output.

Firstly, hand pumps such as this Flux model are an economical alternative to battery, electric or compressed air powered pumps, costing well under £100 each. Furthermore, this hand-operated barrel pump is suitable for dispensing most common chemicals from containers 400 to 1000 mm high.

They are an ideal solution for low volume liquid transfer over short distances, when minimal discharge pressure is required.
