Positive rotary pump in stainless steel

Valfit Engineers offers hygienic and sanitary pumps series in stainless steel. These are positive rotary pumps. All parts in contact with the product liquid are made from AISI 316 quality stainless steel alloys to meet exacting requirements of hygienic standards. As the rotors start to rotate, an expanding cavity is formed by rotation of the lobes, which creates a vacuum at the inlet port, drawing liquid in pumping chamber. The product liquid is carried between the lobes and positively displaced, thereby sealing itself against the internal faces of the pump casing. The other lobe chamber is filled with the product liquid and about to commerce its discharge cycle. Finally the product liquid is forced or passed out of discharge port of the pump in continuous smooth flow and pressure generated by the mashing of the lobe rotors.
