Abstract
A pump for high viscosity materials is mounted on a rectangular frame that fits through a standard doorway. Quick detach latches allow removal of the grate, the hopper or the console, including the control box, from the frame for safer and lighter transportation of the pump. Extendable handles facilitate lifting, moving, and storing the pump. Pivotable wheels with locking mechanisms allows the pump to be moved in any direction by a single user.
Claims17
A pump for high-viscosity materials comprising:
- a frame;
- a hopper for holding high-viscosity materials mounted to the frame;
- the hopper having an outlet;
- an electrically powered motor connected to the frame;
- a high viscosity pump connected to the frame and the hopper outlet;
- the high viscosity pump having a pump outlet;
- a control system controlling the motor;
- a grate covering the hopper and having apertures therein to permit high viscosity material to flow into the hopper through the apertures;
- latches for detachably mounting the hopper to the frame;
- a console holding the control system;
- latches for detachably mounting the console to the frame;
- an electrical connection between the control system and the motor;
- and
- a twist connector between the control system and the motor, such that the console may be detached and removed from the frame by unfastening the latches connecting the console to the frame and disconnecting the twist connector between the control system and the motor, and lifting the console including the control system from the frame.
