Abstract
A pumping system and method according to which a plurality of housings are connected together, with each having an inlet and an outlet for respectively receiving and discharging the liquid to be pumped. A single shaft is driven by a motor and extends though all of the housings, and a plurality of rotors are respectively disposed in the housings and are connected to the shaft for rotation therewith. When the shaft is rotated, the rotors pump liquid passing into their corresponding housings from its inlet, through the housing and out its outlet.
Claims39
A pumping system comprising:
- a plurality of housings connected together, each having an inlet and an outlet;
- a single shaft extending though all of the housings;
- a plurality of rotors respectively disposed in the housings and connected to the shaft for rotation therewith;
- means for rotating the shaft and therefore the rotors to pump liquid into each housing from its inlet for passage through the housing;
- a separator disposed in each housing for separating from the liquid any air that is mixed with the liquid;
- and
- a chamber formed in each housing and having a first portion for receiving the separated liquid and a second portion for receiving the separated air.
A pumping system comprising:
- a plurality of housings connected together, each having an inlet and an outlet;
- a single shaft extending though all of the housings;
- a plurality of rotors respectively disposed in the housings and connected to the shaft for rotation therewith;
- means for rotating the shaft and therefore the rotors to pump liquid into each housing from its inlet for passage through the housing;
- and
- a float assembly disposed in each housing for responding to the liquid level in each housing attaining a predetermined height for recirculating the liquid back to the corresponding inlet.
A pumping system comprising:
- a plurality of compartments connected together, each having an inlet and an outlet;
- a single shaft extending though all of the compartments;
- a plurality of rotors respectively disposed in the compartments and connected to the shaft for rotation therewith;
- means for rotating the shaft and therefore the rotors to pump liquid into each compartment from its inlet for passage through the compartment;
- a separator disposed in each compartment for separating from the liquid any air that is mixed with the liquid;
- and
- a chamber formed in each compartment and having a first portion for receiving the separated liquid and a second portion for receiving the separated air.
A method of pumping liquids from a plurality of sources, the method comprising the steps of:
- connecting a plurality of housings together,
- providing an inlet and an outlet on each housing;
- installing a single shaft extending though all of the housings;
- providing a rotors in each housing;
- connecting the rotors to the shaft for rotation therewith;
- rotating the shaft, and therefore the rotors, to pump liquid into each housing from its inlet and through the housing;
- separating from the liquid in each housing any air that is mixed with the liquid,
- routing the separated liquid to a first portion of a chamber formed in each housing;
- and
- routing the separated air to a second portion of the chamber.
A pumping system comprising:
- a plurality of compartments connected together, each having an inlet and an outlet;
- a single shaft extending though all of the compartments;
- a plurality of rotors respectively disposed in the compartments and connected to the shaft for rotation therewith;
- means for rotating the shaft and therefore the rotors to pump liquid into each compartment from its inlet for passage through the compartment;
- and
- a float assembly disposed in each compartment for responding to the liquid level in each compartment attaining a predetermined height for recirculating the liquid back to the corresponding inlet.
