VL pumps are self-priming positive displacement rotary lobe pumps. The flow rate varies proportionally with the rotational speed. Two counter-rotating lobes transfer the pumped medium from the inlet to the outlet, drawing it into the pockets created between the lobes and the pump body.
The VL pump enables the transfer of viscous and fibrous products, sludges, pastes, and even slurries containing abrasive and suspended solid materials, with a maximum particle size of 30 mm.
The pump is self-priming up to a depth of 5 m (with water).
