The D-D Function series pumps are multi-function DC pumps with a unique digital control that offer three different wave modes and a constant flow function. Also suitable for operating media reactors or as a pump for a closed circuit (models 5000/6500/10000 only).

The sine wave technology and low voltage motor are suitable for use in salt or fresh water and offer extremely low operating noise, low heat emission and high energy efficiency.

The functions

Continuous mode

The pump can be set for continuous operation to use as a standard return, reactor or equipment supply pump. The flow setting can be adjusted on the controller between the minimum and maximum power settings of 30 and 100.

Wave mode

A constant shaft power is generated as the pump ramps up and down between a minimum and maximum power setting. The frequency and power settings can be changed on the controller

Pulse mode

The pump speed alternates between a low and high power setting and can be used to create a standing wave. The frequency and power settings can be changed on the controller.

Storm mode

The pump's power alternates between different power levels at different frequencies to create a random flow pattern. Ideal for stirring up detritus so that it can be removed through filtration
