The "U" (Universal)
2000 offers infinitely variable flow from zero to 100% by varying
the eccentricity of the shaft to rotor mechanism within the pump.
The eccentricity can be varied in three ways:
1. Manually at the pump by a
handwheel situated on top of the pump
2. Remotely from a control center with a pneumatic or electric
stroke actuator n top of the pump.
3. Automatically by C.P.C. (constant pressure control) where
pump flow is automatically adjusted to suit a constant system
design pressure
Energy absorbed is proportional
to the eccentricity (flow) setting, offering considerable energy
savings over conventional fixed flow pumps using systems pressure/flow
control valves. The C.P.C system is particularly suited
to automated blending plants where blending vessels and filling
machines have constantly varying flow requirements.
