All Parts in contact with the product liquid are made from AISI-316 quality stainless steel alloys to meet exacting of hygienic standard.
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 displayed, thereby sealing itself against the internal faces of the pump casing.
The other lobe chamber is filled with the product liquid and about to commence it's discharge cycle.
Finally the product liquid is forced or pressed out of discharge port of pump in continuous smooth flow and pressure generated by the lobe rotors.
Built-in-with relief valve : This is also fully interchageable. But the adjustable automatic spring loaded pressure relief valve provides a definite means of protection.
Jacketed Front Cover : Jacketed rotor case front cover suitable for heating and cooling with any medium (Water, Steam, Oil etc. A built-in-relief valve cannot be used if this type of front cover is fitted).
