Description
Overview
The QBK15 aluminium air-operated double diaphragm pump moves up to 20 L/min through 1/2″ ports, powered by compressed air alone. It self-primes to a 7 m suction lift, delivers up to 6.9 bar, passes solids up to 1 mm and carries PTFE (Teflon) diaphragms.
The aluminium body is the cost-effective choice for fuels, oils and water-based liquids, and it keeps the pump light enough to move by hand. For acids or caustic liquids, choose the polypropylene or stainless steel versions instead. Because there is no electric motor, you can run it wherever you have an air line, and it keeps pumping against a closed outlet. Browse more diaphragm pumps, or compare the QBK15 polypropylene diaphragm pump and the QBK15 diaphragm pump seal kit.

Where it works
Workshops and small plants use a pump this size to decant oils, paints, inks and cleaning chemicals from drums into smaller containers, and to feed dosing points where flow is modest. It also suits laboratories, small agri-chemical stores and maintenance teams who need a portable air pump that fits in a bakkie. Limpopo workshops and Gauteng service centres often keep one beside the oil store.
Fit an air filter and regulator, and match your compressor to the 300 L/min maximum air consumption.

Questions about this product
What compressor do I need for the QBK15?
The QBK15 uses up to 300 L/min of compressed air at full flow, so size your compressor to deliver at least that at working pressure. A smaller compressor still runs the pump but limits its flow. Fit an air filter and a regulator so you can throttle flow and pressure, and keep air pressure at or below 6.9 bar.
Can the aluminium QBK15 pump diesel and oil?
Yes, aluminium suits diesel, oils and many water-based liquids, and it is lighter and cheaper than stainless steel. Avoid strong acids and caustic liquids, which attack aluminium. For those, choose the polypropylene or stainless steel version. Tell us the liquid and we will confirm the right body before you order.
