Understanding the Specifications

Flow Rate (LPH)

Measured in litres per hour, this indicates how much water the pump can move. Higher flow rates are generally suited to larger aquariums and higher sump turnover.

Power Range

Because the pump is fully controllable, power consumption varies with speed setting. This means you only use the energy needed for your system.

Inlet / Outlet Size

These measurements determine plumbing compatibility and help ensure optimal flow through your return system.

Pump Size

Physical dimensions matter when fitting pumps into tighter sump chambers or cabinet spaces.
