VL are positive displacement rotary lobe selfpriming pumps. Flow rate varies proportionally to the rotation speed. Two opposite rotating lobes transfer, from the inlet to the outlet, the pumped media drawn into pockets that are formed between the lobes and the pump housing.
VL pump allows the transfer of viscous and fibrous products, slurries, sludges, pastes and muds also containing abrasive and suspended solids with a maximum size of 30 mm.
The pump is selfpriming down to 5 m depth (with water).
