DXB Solutions LLC supplies open impeller pumps in UAE for industrial water transfer, wastewater, food processing, washing systems and applications involving liquids containing suspended particles or small solids. Open impeller centrifugal pumps are designed with an impeller that is not fully enclosed by front and rear shrouds, allowing suitable liquids containing solids or fibrous material to pass through the hydraulic section more easily than in many conventional closed-impeller pumps.
Our open impeller pump solutions can be selected according to the required flow rate, total dynamic head, solids size, liquid characteristics, temperature and material requirements.
Open Impeller Centrifugal Pumps
An open impeller centrifugal pump uses an impeller with exposed vanes rather than a completely enclosed impeller structure.
As the impeller rotates, it transfers energy to the liquid and creates the flow and pressure required to move the fluid through the system.
The open hydraulic design can make these pumps suitable for liquids containing suspended particles that may be unsuitable for conventional clean-water centrifugal pumps.
Liquid enters the pump through the suction connection and reaches the centre of the rotating impeller.
The impeller blades accelerate the liquid outward into the pump casing, where velocity is converted into pressure before the liquid leaves through the discharge connection.
The comparatively open passage around the impeller can provide improved solids-handling capability compared with many closed-impeller clean-water pumps.
However, the maximum permissible solids size depends on the specific pump model and manufacturer.
Open Impeller Pumps for Wastewater
Open impeller pumps can be used for suitable wastewater applications where the liquid contains suspended particles or small solids.
They can be useful for:
Industrial wastewater • Washing water • Process water • Contaminated water • Drainage applications
For sewage containing larger solids, fibrous material or heavy contamination, a dedicated sewage, vortex, cutter or grinder pump may be more appropriate.
Stainless Steel Open Impeller Pumps
Stainless-steel open impeller pumps provide a useful solution where corrosion resistance and hygienic material properties are required.
Depending on the manufacturer and model, pumps may be available in AISI 304 or AISI 316 stainless steel.
Applications can include suitable:
- Food-processing systems
- Washing equipment
- Industrial water transfer
- Process-water systems
- Commercial kitchens
- Cleaning systems
Material compatibility should always be checked against the pumped liquid.
Open Impeller Pumps for Food Processing
Certain stainless-steel open impeller pumps can be used in food-processing and washing applications where the specific pump design and materials are suitable.
Possible applications include:
Vegetable washing • Food-processing equipment • Cleaning systems • Commercial kitchens • Industrial washing
For hygienic or food-contact duties, confirm the manufacturer’s specific approvals and material requirements rather than assuming every stainless-steel open impeller pump is food-grade.
Open Impeller Pumps for Industrial Applications
Industrial processes may involve water containing suspended particles or liquids that cannot be handled efficiently by conventional clean-water pumps.
Open impeller pumps can provide an appropriate solution for selected industrial washing, process-water, wastewater and liquid-transfer applications.
