Inverter Drive Self Priming Flexible Impeller Pump

Our INV-BS Self Priming Flexible Impeller Pump Series is characterised by featuring either the close-coupled MINOR 40 or MAJOR 60 pump units fitted with forced ventilated motors onto a 2-wheel trolley system. All flow control is located on the control panel, and dry run protection isn’t featured.

The speed adjustment range has been limited to 175 – 1400 rpm due to the absence of a gearbox, as opposed to a minimum speed of 50 rpm capable with the INV series.

The INV-BS is a cost-effective alternative to the INV series, which you can find here: VA & INV Self Priming Flexible Impeller Pumps.

Due to the 4 kW inverter drive system, the feeding supply for both models needs to be 400V three-phase. Manual or Spring Loaded By-Passes are also available on request.
