Sparus Pump with Constant Flow Tech (up to 530LPM)

Work out your required flow and your total head, including pipe friction and any filter or UV losses, then pick the model that meets that flow at that head — with the Sparus you then simply key that flow in, anywhere from 75 to 530 LPM.

The on-board drive continuously adjusts motor speed to hold the flow you set, so the flow stays the same as head changes — for example as a drum filter or biofilter loads up, or a valve is moved.

Aquaculture systems are designed around a known turnover rate, and a fixed-speed pump loses flow as head rises; the Sparus holds the design flow, which is why it is our recommended pump for the a3 Aeration Nozzle.

Yes — it is supplied with salt water rated seals and an IP55 enclosure for wet and harsh conditions.

Yes — a digital communication port allows monitoring and control from a PLC or SCADA system; contact us for PLC solutions.

230 V single phase 50 Hz on a 3 HP permanent magnet TEFC motor, with 50 mm (2 inch) internally threaded NPT inlet and outlet ports.

Yes — because it runs only as fast as it needs to for the flow you set, rather than being throttled back at a valve, it uses the minimum energy required to deliver that flow.
