Hand & Siphon Pumps

30 products available

Compel supplies professional-grade hand fuel pump units and siphon pump assemblies for maintenance facilities, commercial fleet depots, and industrial plants. When powered transfer pumps are unavailable or hazardous, a dependable manual fuel pump provides controlled dispensing and fluid evacuation. Our inventory covers heavy-duty primer bulbs, manual suction syringes, shaker assemblies, and lever-action drum press heads designed for routine workshop and site service.

Whether technicians need a hand pump for fuel lines or an oil pump extractor for gearboxes, we stock reliable configurations built from fuel-grade rubber, PVC, brass, and aluminum alloy. Compel delivers tested transfer equipment directly to your site with consistent stock availability and rapid international dispatch.

Selecting the Right Manual Pumping Mechanism

Different maintenance routines demand distinct pumping actions. Primer bulbs and squeeze assemblies use continuous manual compression to initiate gravity flow, making them ideal as an emergency siphon pump for fuel tanks and drums. For measured fluid extraction, manual syringe pumps provide calibrated suction to pull exact volumes from reservoirs without spillage.

Bulk transfer from 200-litre containers requires a mechanical drum press head or lever action unit. Self-priming shaker pumps offer rapid fuel transfer without electric power by using an internal check valve activated through vertical oscillation.

  • Squeeze primer bulbs: Quick line priming and gravity-assisted fuel transfer up to 5 L/min.
  • Suction syringes (e.g., 200 ml capacity): Calibrated extraction of transmission fluids, brake fluids, and differential oil.
  • Drum press and lever pumps: Bulk fluid evacuation directly from barrels and vertical storage tanks.
  • Shaker siphon tubes: Self-priming fluid movement using brass or alloy check valves.

Fluid Compatibility and Chemical Resistance

Matching the pump material to the media is necessary to prevent seal degradation and fluid contamination. Petrol, diesel, engine oil, and hydraulic fluid degrade standard plastics over time. Industrial transfer assemblies use oil-resistant rubber bulbs, clear PVC transfer hoses, and aluminum alloy fittings to maintain vacuum integrity.

For heavier lubricants and non-corrosive workshop liquids, check fluid ratings closely. Syringe extractors built with chemical-resistant plungers handle aggressive fluids like brake fluid and gear lube, whereas standard fuel siphon tubes target light petroleum distillates, diesel, and water.

Hose Specifications and Connection Hardware

Hose dimensions determine transfer speed and access clearance. Most standard hand siphon systems feature an 8 mm inner diameter hose with lengths ranging from 1 m to 2 m. Shorter 20 cm or 200 mm rigid tubes suit precise syringe work in tight engine bays.

Look for integral backflow prevention valves to prevent fluid drain-back and maintain prime between pump strokes. For marine gearboxes and lower units, select units equipped with threaded adapters, such as a 3/8-inch metal swivel fitting, to ensure a leakproof mechanical seal during oil injection.

Choosing Hand & Siphon Pumps

When should I choose a hand fuel pump over a suction syringe?
Choose a hand fuel pump with a primer bulb or siphon tube when moving larger liquid volumes between containers, tanks, or drums. A manual suction syringe is calibrated for small, precise fluid extractions up to 200 ml, such as adjusting brake master cylinders or differential reservoirs.
Can a standard siphon pump for fuel handle transmission fluid and heavy gear oils?
Standard gravity-fed siphon pumps struggle with high-viscosity oils and cold lubricants. You should select a high-vacuum oil pump fluid extractor or a syringe-style extractor rated for engine oil, gear oil, and transmission fluids to generate sufficient suction force.
What materials are used in industrial siphon and fuel hand pumps?
Industrial hand pumps use nitrile or reinforced rubber bulbs, clear PVC tubing, and aluminum or brass check valves. These materials resist chemical softening from diesel, petrol, and lubricants while maintaining an airtight seal under vacuum.
What flow rate can a manual hand pump for fuel achieve?
A manual fuel pump primer assembly with an 8 mm inner diameter hose typically delivers a flow rate of around 5 L/min under continuous operation. Final transfer speeds depend on hose length, fluid viscosity, and the height differential between fluid levels.
Can I use these hand pumps to transfer corrosive acids or solvents?
No. The representative hand and siphon pumps in this category are rated strictly for fuel, diesel, light oils, water, and non-corrosive workshop liquids. Never use them for acids, volatile thinners, or hazardous chemicals unless specifically stated on the product datasheet.
