Pirani vacuum gauge: The resistance vacuum gauge, also known as the Pirani gauge, responds to changes in pressure due to changes in the resistance of the filament. It is mainly composed of two parts: regulatory and measurement lines. Its measurement range is 104 to 10-1 Pa. The structure of the ...

The new type dual stage water ring pump can complete replace the SIHI LPH series pump from the pump performance, power and outline dimension. Even though our DLV pump parts can replace the SIHI pump parts. Such as the impeller as follow: Our pump impeller has no holes, but SIHI has two holes, be...
