Bellin progressive cavity pumps have been designed for easy, low maintenance: wear parts can easily be replaced on the site. Eccentric screw pumps are heavy duty pumps and they can be used to pump abrasives sludges, viscous products, oils, emulsions etc. Due to the steady non turbulent flow they can also handle shear sensitive products and medium with solids content without breaking up the solids.
|ADVANTAGESBellin progressive cavity pumps have many advantages over other types of pumps which allow use extremely diverse:
||Pump “PRESSURE” depends on the number of rotor/stator stages:|
up to 6-7 BAR
up to 12-14 BAR
up to 24-28 BAR
The “progressive cavity pumps” are “positive displacement” pumps. The 2 principal parts are the “rotor” (round thread screw) which turns eccentrically inside a fixed rubber part, the “stator” (vulcanized rubber into a steel cylinder) – moving the fluid in a series of cavities along the axis of the pump.
“Theoretical capacity” is in relation to the pump speed and to rotor dimension. Theoretical capacity is as below:
Qth = 4*e*D*Ps*n*60
- Qth Theoretical capacity [me = Eccentricity of rotor [m>[/m
