Impeller Pump, p-max: 280 mbar, Q-max: 5,8 l/min

The 41.007.400 series pump is designed to increase pressure and improve dosing consistency.

It is ideally suited for applications where a low water level in a boiler causes insufficient flow through conventional outlet valves.

The use of the pump allows a largely independent placement of outlet valves above the water level of the boiler.
The special design of the hydraulic part of the pump enables low-cavitation operation. High media temperatures of up to 96 °C are therefore possible without significant loss of pump performance.

To increase the maintenance intervals, a low-wear, brushless motor is used in this pump.
By using the bayonet lock, the pump can be easily dismantled and cleaned.

The pump housing is suitable for hot water and has a long life cycle of more than 1500 hours (tested under laboratory conditions) due to the high end materials and design solutions used.
This is achieved by hermetically separating the drive unit from the hydraulic unit. Leakage, as is common on the seals otherwise used on rotating drive shafts, is thus prevented.

The pump is equipped with vibration dampers that further minimise the already very low noise emissions when installed.
