Bioscape Diaphram 3000 Air Pump 2 Pack
A replacement pair of diaphragms for the Bioscape Tropic Air Pump 3000. This two-pack keeps a BIS53 twin-outlet pump running at full pressure once the original rubber diaphragms wear out, without paying for a whole new pump.
Key features
- Confirmed fit for the Air Pump 3000 – Bioscape's own part numbering (BIS53 pump → BIS53A diaphragm) and a matching retailer listing both identify this as the 3000's diaphragm.
- Two per pack – a twin-outlet pump uses two diaphragms, so one pack fully services one pump.
- Restores pressure on both outlets – a worn diaphragm on either side shows up as weaker airflow from that outlet specifically.
- Cheaper than a new pump – keep the motor and housing, replace only the wearing part.

Which air pump does this fit?
This is the diaphragm for the Bioscape Tropic Air Pump 3000 (BIS53), a twin-outlet pump rated for tanks from about 50 up to 300 litres. It's not the diaphragm for the smaller 500/1000 or 2000 pumps, or the larger 4000/8000 – check your pump's model number first.
Suitable for, and not suitable for
- Suitable for: servicing a Bioscape Tropic Air Pump 3000 (BIS53).
- Not suitable for: other Bioscape Tropic pump sizes or other brands' air pumps.
Care and maintenance
Replace both diaphragms together once you notice weaker airflow from one or both outlets, or the motor running noisier than usual. Bioscape hasn't published a fixed replacement interval; go by performance.
Warranty and delivery
Covered by your consumer guarantee rights under Australian Consumer Law if it arrives faulty. Ships as a small parcel.
Common questions
Does one pack service the whole pump?
Yes – the Air Pump 3000 is a twin-outlet pump with two diaphragms, and this pack contains two, enough for a full service.
Will this fit the Air Pump 2000 or 4000/8000?
No. Each size in the range uses its own diaphragm – this one is for the 3000 (BIS53) only.
How many diaphragms come in the pack?
Two.
