Self-priming water pressure systems with two connected pumps with electronic control speed motor related to the flow rate. Delayed start of the auxiliary pump. Reduced consumption and noise. Accumulator tank is not required. Protected against overloads. Pump functions monitored by 2 LEDs. “Empty tank” signal and shut-off device. Available also with control panel. Two versions available, 2.5 bar and 3.5 bar. Both versions are 24Vdc. The item presented on this page is the 3.5 bar variant.

This pump features Marco's Intelligent Brain ECU system.  The pump is able to detect the constant pressure in the plumbing system and respond accordingly when the pressure drops caused by an outlet being used.  The means that the pump can respond to demand and only ever works at the appropriate speed for any given usage.  Advantages of this system include:

• Quieter running - pump rarely needs to run at full speed
• Longer lasting - a more mechanically sympathetic arrangement
• Less consumption
• No need for accumulator/expansion tank*
• Intelligent programming and inclusion with digital switching systems
• Fault finding - ECU logs error codes and allows for faster diagnostics

* Please consult our technical department if intending to install this pump without an accumular tank.  There are some scenarios in which an accumulator tank will still be required.
