Collection: Hiblow Air Pumps

What linear pumps are for

Hiblow's linear diaphragm pumps are continuous-duty equipment. They cost more and take more space than a standard aquarium air pump, and they exist for work that would destroy one: fish rooms feeding many sponge filters, holding systems, densely stocked tanks, and pond aeration. The HP range runs from compact units up to the largest models, with Long Life variants available.

How the spares are organized

• Repair kits cover paired models — 10/20, 30/40, 60/80, 100/120 and 150/200.
• Diaphragms and intake filters wear in normal service and get replaced periodically.
• Base gaskets, mounting blocks, rod blocks and chamber blocks are available individually.
• Order against the exact model number printed on the pump, not a similar size.

Rebuild, don't discard

These pumps are built to be serviced, which is why the parts list runs this long. Fitting a fresh diaphragm set and filter restores a worn pump instead of forcing a replacement purchase, and that serviceability is what justifies the higher price over years of running. If a single pump is aerating an entire stocked system, keeping its repair kit in stock is cheap insurance.
