Koi Air from Blagdon
Koi Air 65 - from Blagdon.
This pump particular pump will deliver 65 liters/minute at 60 watts and is supplied with a white plastic manifold, (which is unfortunately about as good as a Chocolate Fireguard)
So may we dare suggest that you perhaps consider buying a 'real' manifold with 6 air tap outlets.
A slightly smaller model but ideal for the beginners pond of up to 2,000 gallons is the Koi Air 50 - which produces 50 liters/minute at 40 watts.
The 'baby' of the family - the Koi Air 25 is fine for that starter pond or quarantine tank and produces 25 lpm at 20wts
