Oase Pump Vault 20000

Oase Pump Vault 20000

Accessible pump chamber for Oase Maxima pondless reservoirs

The Oase Pump Vault 20000 creates a protected, serviceable chamber beside a field of Maxima storage blocks. Instead of burying the circulation pump among rocks or inside the reservoir matrix, the vault gives it a dedicated space with access from the finished surface. That makes routine intake cleaning, winter work and pump replacement far more practical.

The 685 × 406 × 400mm chamber is designed for flows up to 20,000 litres per hour. A 110mm side cut-out connects to the surrounding water-storage area, and the body accepts appropriate pipework and pump arrangements up to the manufacturer’s stated limits. Pump selection still depends on the complete circuit: waterfall flow, vertical lift, hose bore and friction all matter.

Compatibility and system planning

Combine the vault with Oase Maxima 60 or 120 blocks and a correctly protected liner to form the hidden reservoir. Use an Oase Spillway Box where the return needs a calm, distributed start at the top of a stream. An AutoFill Kit can help maintain the running level where evaporation and splash loss are significant.

Frequently asked questions

Is the pump included?

No. The vault is the access chamber; choose the pump for the real duty point.

Can it be used without Maxima blocks?

It may form part of another correctly designed hidden reservoir, but its connections, support and liner interface must remain structurally sound.

Can I bury the lid?

It may be visually concealed, but it must remain removable for servicing.
