A pump or combination pump/mixer device is disclosed. The pump or pump/mixer uses moving diaphragms in combination with check valves to pump and/or mix fluid. A main inlet is located at the top of the pump and is fed by a vessel or container that contains fluid. The fluid, in response to the moving diaphragms, passes through an outer chamber into a plurality of lower chambers and then into a central chamber where the fluid then exits via one or more outlets. A series of check-valves are used to ensure one-way flow of fluid through the chambers. The drive shaft of a motor or drive unit drives a nutating disk or wobble plate that actuates the diaphragms to drive fluid through the device. In the pump/mixer configuration, one or more additional inlets are provided to input additional fluids into the device for mixing within the inside of the pump/mixer.

A mobile chemical mixing plant includes an inlet for receiving fluid; a fluid conduit for conveying the fluid from the inlet; a container for containing a chemical therein; a chemical pump for withdrawing the chemical from the container and directing the chemical into the fluid conduit for mixing with the fluid in the fluid conduit to form a chemical mixture; and a homogenization pump for pumping the chemical mixture in the fluid conduit out of the mobile chemical mixing plant. The fluid conduit connects the chemical pump to the homogenization pump. The mobile chemical mixing plant is fixed to a trailer that is attachable to a vehicle. Because the fluid conduit directly connects the chemical pump to the homogenization pump, the mobile chemical mixing plant does not need an intervening mixing tank for mixing the fluid and the chemical.

Provided is a generating method for generating an ultra-fine bubble-containing liquid in which multiple types of UFB s of different gas components are mixed at a desired concentration ratio, and a manufacturing apparatus for a liquid containing ultra-fine bubbles. Multiple types of UFB-containing liquids are generated for each gas contained by the UFBs, and the UFB-containing liquids are mixed with each other based on a mix proportion of a desired UFB concentration.

In one example, a dispensing system has a housing that supports a first and second pumps. The housing defines a receptacle and first and second passages. The receptacle defines at least one hole that extends into the housing that can receive a plug of a fluid dispenser. The first passage extends from the at least one hole to a first pump outlet, such that the first passage can communicate a first fluid material from the first pump outlet to the fluid dispenser. The second passage extends from the at least one hole to a second pump outlet, such that the second passage can communicate a second fluid material from the second pump outlet to the fluid dispenser. The system has an engagement feature that can engage a corresponding feature of the plug of the fluid dispenser so as to releasably secure the fluid dispenser to the housing.

Disclosed cyclonic flow-inducing pumps overcome drawbacks associated with known adverse flow conditions that arise from flow of certain types of materials through a material flow conduit. Such cyclonic flow-inducing pumps provide for flow of flowable material within a flow passage of a material flow conduit (e.g., a portion of a pipeline, tubing or the like) to have a cyclonic flow (i.e., vortex or swirling) profile. Advantageously, the cyclonic flow profile centralizes flow toward the central portion of the flow passage, thereby reducing magnitude of laminar flow. Such cyclonic flow profile provides a variety of other advantages as compared to a parabolic flow profile such as, for example, increased flow rate, reduce inner pipeline wear, more uniform inner pipe wear, reduction in energy consumption, reduced or eliminated adverse considerations such as slugging.

The application is directed to a system and method for mixing fluid and dry material to produce fluid mixture compositions. The system may be provided on a portable platform for transport of the system for use at different locations or the system may be provided as a permanent installation. The system includes a first module for receiving fluid into the system and an optional second module attachable to the first module for providing dry material to be mixed with the fluid received into the system. The fluid mixture compositions produced by the system can be conveyed out from the system to one or more target locations.

A jet injection device that incorporates nanobubbles (ultrafine bubbles) in a mist includes: a two-fluid nozzle configured from a circular nozzle outer cylinder and an air connection tube integrally and perpendicularly connected to the nozzle outer cylinder; a nanobubble generation device that supplies the nozzle outer cylinder of the two-fluid nozzle with high-pressure nanobubble water; and a compressor that supplies the air connection tube of the two-fluid nozzle with high-pressure air. The gas-injected bubble water generated from the nanobubble generation device is pressure-fed to the nozzle outer cylinder of the two-fluid nozzle, and compressed air from the compressor is pressure-fed to the air connection tube of the two-fluid nozzle. In the two-fluid nozzle, the high-pressure gas-injected bubble water and the compressed air serve as a gas-liquid fluid mixture, and are injected at a high speed in mist form from a nozzle cylinder of the two-fluid nozzle.

The present invention relates to a micro-bubble pump apparatus for a water treatment, and the micro-bubble pump apparatus for a water treatment comprises: a motor for generating rotatory power; and a micro-bubble pump connected to the motor and for mixing a feed liquid which flows into one side thereof and a feed gas which is injected into the other side thereof.
