Abstract
An improved high viscosity pump system and its rotor are disclosed herein. In an embodiment, a high viscosity pump system includes a motor, a housing having an inlet and an adjacent rotor space, and a rotor. The rotor is located within the rotor space of the housing and is configured to be driven by the motor around a rotational axis. The rotor includes a first plate and a second plate that rotate together around the rotational axis to pump liquid, material or slurry from the inlet to discharge or an outlet.
Claims20
A high viscosity pump system comprising:
- a motor;
- a housing having an inlet and an adjacent rotor space;
- and
- a rotor located within the rotor space of the housing and configured to be driven by the motor around a rotational axis, the rotor including a first plate and a second plate that rotate together around the rotational axis to pump liquid, material or slurry from the inlet to discharge or an outlet,
- the first plate including a first inner plate surface, a first outer plate surface, a first circumferential surface, a plurality of first blades projecting from the first inner plate surface, and a plurality of first thickened portions projecting from the first outer plate surface and being wider than the first blades at the first circumferential surface, and
- the second plate including a second inner plate surface, a second outer plate surface, a second circumferential surface, a plurality of second blades projecting from the second inner plate surface, and a plurality of second thickened portions projecting from the second outer plate surface and being wider than the second blades at the second circumferential surface.
A rotor for a pump system, the rotor comprising:
- a first plate including a first inner plate surface, a first outer plate surface, a first circumferential surface, a plurality of first blades projecting from the first inner plate surface, and a plurality of first thickened portions projecting from the first outer plate surface and being wider than the first blades at the first circumferential surface;
- and
- a second plate including a second inner plate surface, a second outer plate surface, a second circumferential surface, a plurality of second blades projecting from the second inner plate surface, and a plurality of second thickened portions projecting from the second outer plate surface and being wider than the second blades at the second circumferential surface,
- the first plate and the second plate having a fixed connection provided by at least one connecting element extending from the first inner plate surface to the second inner plate surface, the fixed connection causing the first plate and the second plate to be separated by a gap and to rotate together around a rotational axis.
A rotor for a pump system, the rotor comprising:
- a first plate configured to rotate around a rotational axis and having a solid surface intersecting the rotational axis, the first plate including a first inner plate surface, a first outer plate surface, a first circumferential surface, a plurality of first blades projecting from the first inner plate surface, and a plurality of first thickened portions projecting from the first outer plate surface and being wider than the first blades at the first circumferential surface;
- and
- a second plate fixed to the first plate so as to be separated from the first plate by a gap, the second plate configured to rotate around the rotational axis together with the first plate, the second plate including a plate aperture at the rotational axis, a second inner plate surface, a second outer plate surface, a second circumferential surface, a plurality of second blades projecting from the second inner plate surface, and a plurality of second thickened portions projecting from the second outer plate surface and being wider than the second blades at the second circumferential surface.
