Omnifab’s reputation for repairing and maintaining industrial machinery is well established. Among the equipment covered by this expertise are industrial pumps.
These pumps, which come in many shapes and sizes, are designed to deliver superior performance and durability. They need to be inspected and maintained on a regular basis. This is the key to optimum performance and reduced risk of breakdown.
In the following paragraphs, learn more about pump maintenance and our ability to take care of the industrial pumps of a multitude of companies from a variety of sectors.
« Industrial pumps » definition
In the widest sense, a pump can be defined as a mechanical device capable of converting the mechanical energy of its motor into hydraulic energy to ensure the transfer of a fluid from one place to another.
When we speak of “industrial” pumps, we are generally referring to equipment designed specifically for highly demanding applications or intensive use.
Industries where industrial pumps are used
Industrial pumps can be found in many environments, such as :
- The industrial sector
- Municipalities
- Wastewater management
- And more!
Omnifab also has a strong presence in public water supply systems. In fact, we cover no less than 15 municipalities when it comes to the maintenance and repair of wastewater pumps.
The types of industrial pumps we can work on
1. Centrifugal pump
A centrifugal pump is a rotating machine that pumps liquid by forcing it through an impeller. This is the most common type of industrial pump.
2. Submersible pump
A submersible pump, also known as an immersed pump, is an electromechanical device designed to pump liquids, usually water, from locations below the surface, such as wells, reservoirs or deep wells. Unlike conventional pumps, which are installed on the surface and suck in the liquid, a submersible pump is placed directly in the liquid to be pumped.
3. Diaphragm pump
A diaphragm pump is a type of volumetric pump used to move liquids, gases or suspensions. It is distinguished by its pumping mechanism, which relies on a flexible diaphragm to create fluid displacement.
4. Gear pump
As the name suggests, gear pumps are rotating devices. The rotation of the gear allows the fluid to flow and the pressure to build up within the casing.
5. Lobe pump
A lobe pump is a type of volumetric pump. Due to their excellent sanitary qualities, efficiency, reliability and resistance to corrosion, lobe pumps are used in a wide range of industries (chemical, food, pharmaceutical, biotechnology, etc.).
6. Screw pump
The screw pump is a powerful device for high-viscosity, high-filling, coarse-grained or even fibrous products. This makes it one of the most robust pumps on the market, and one that’s easy to use.
7. Piston pump
This is a volumetric pump whose operation is based on the variation in volume of a chamber in which one or more pistons move in a single- or double-acting alternating rectilinear motion.
8. Water pump
“Water pump” is a term used to describe pumps whose function is to move water from one place to another. Several types or families of pumps can therefore be described as water pumps (booster pump, lift pump, surface pump, chopper pump, etc.).
9. Circulation pump
A circulation pump, also known as a recirculation pump, is a type of pump used to move liquid within a closed system or circuit. Its main purpose is to maintain a continuous flow of liquid through a closed circuit, such as a heating, cooling or hot water circulation system.
10. Sewage pump
The sewage lift pump is ideal when gravity drainage is not possible. This device enables water to be lifted and discharged into the independent or collective sewage system.
11. Vertical turbine pump
The electric motor of a vertical turbine pump remains above the fluid to be pumped. A long vertical shaft transmits the movement initiated by the motor to the impellers, which direct the fluid upwards. This type of industrial water pump is used in municipal systems to distribute drinking water to citizens, or to supply water to fire-fighting services.
12. Pressure boosters
A booster pump, also known as a pressure booster or hydrophore unit, is used to increase water pressure when there are concerns about under-pressure. A booster pump consists of a pump and a bladder or diaphragm tank that absorbs water and pressurizes it.
Summary Table of Industrial Pump Types
| Pump Type | Working Principle | Main Applications | Key Points |
| Centrifugal Pump | Dynamic pump using one or more impellers (rotors) to transfer centrifugal energy to the fluid. | Wide range of industries, liquids with suspended solids. | Prone to cavitation; wide variety of models available. |
| Submersible Pump | Dynamic pump with a sealed, watertight motor, fully immersed in the fluid. | Wastewater, stormwater, chemicals, gray water, food products. | Never requires priming; built for extreme conditions. |
| Diaphragm Pump | Positive displacement pump with membranes actuated pneumatically or electrically. | Chemicals, volatile solvents, corrosive liquids, dosing. | Highly resistant to aggressive fluids. |
| Gear Pump | Positive displacement pump with rotating gears that create suction and discharge. | Oils, grease, thick non-solid liquids. | Prevents backflow thanks to the unidirectional rotation of gears. |
| Lobe Pump | Positive displacement pump with rotating lobes that create suction and trap fluid. | Dense liquids, liquids containing solids. | Lobes do not touch; gentle handling of fluids. |
| Screw Pump | Positive displacement pump in which rotating screws move the fluid via internal pressure. | Water, oils, fuels, high-viscosity materials. | Smooth, continuous flow; ideal for viscous liquids. |
| Piston Pump | Positive displacement pump with a piston that alternates between suction and discharge. | Liquid transfer, complex pumping systems. | Can include a check valve; capable of high pressure. |
| Water Pump | Generic term encompassing various types of pumps designed to move water. | Boosting, lifting, water transfer, irrigation. | Broad category (surface, booster, lifting, etc.). |
| Circulation Pump | Dynamic pump that maintains a continuous flow in a closed circuit. | Heating, cooling, domestic hot water. | Ensures constant recirculation. |
| Wastewater Pump | Used to lift water when gravity flow is not possible. | Individual or collective sanitation networks. | Essential to prevent backflow. |
| Vertical Turbine Pump | Dynamic pump with a vertical shaft transmitting motion to submerged impellers. | Drinking water distribution, municipal networks, fire service circuits. | Motor remains above fluid; ideal for large volumes of water. |
| Booster System | Pump + bladder/diaphragm tank that pressurizes water. | Compensates for low water pressure. | Ensures constant system pressure. |
Trust our experts with your industrial pumps
Omnifab can intervene in a number of ways to boost the efficiency of your pumps
