Choosing the right pump is an important decision across all industries, directly impacting production efficiency, cost reduction, and asset life. Among the many types of pumps, single-screw or twin-screw pumps occupy a special position due to their special design and unique performance characteristics. These pumps are particularly effective at pumping highly viscous liquids or liquids with solid particles.
In this article, we will take a closer look at the mono pump, look at its advantages and applications in different industries, and compare it to other pumps.
What is a slurry pump and how does it work?
A mono pump is a positive displacement pump consisting of a metallic screw rotor and a rubber stator . The rotation of the rotor creates cavities that ensure a smooth flow of fluid from the inlet to the outlet.
The main advantage of the mono pump is its ability to pump very thick and viscous liquids or liquids with solids, which is a problem for many other pumps.
Main advantages of mono pumps
1. Possibility of pumping highly viscous liquids.
One of the most important advantages of a single pump is that it can easily pump liquids such as honey, yogurt, thick sewage, heavy oil, or drilling mud.
2. Smooth and shock-free transmission.
In many industrial processes , pressure or flow fluctuations can cause product damage. Mono pumps are specially designed for uniform and quiet conveying.
3. Possibility of transporting solids with liquids.
The pump can transport suspended solids such as pieces of fruit in the food industry or abrasive materials in the oil and mining industries without causing serious damage to the system.
4. Ability to self-prepare
The mono pump can pump liquids under various conditions even without prior preparation. This feature simplifies installation and operation.
5. Suitable for different flow rates and pressures.
Due to the displacement design, these pumps can be operated at high pressure without any significant loss of performance.
6. Easy maintenance and repair
Although stationary and rotating parts wear , out over time , replacing them is relatively easy and does not require long production line downtime.
7. Improve energy consumption
Because monopumps move fluids very efficiently, they consume less energy than some centrifugal pumps.
Advantages of single-stage pumps in various industries
1. Food industry
-
Transfer yogurt, honey, date syrup, jams, and sauces without affecting the texture.
-
Ensures consistent pumping and prevents air build-up during the process.
-
Approval of a solid part intended for food in accordance with hygiene standards.
2. Pharmaceutical and cosmetic industry
-
Transports highly concentrated creams, lotions and gels.
-
Avoid product contamination with hygienic design and clean-in-place (CIP) capabilities.
3. Oil, gas and petrochemical industry
-
Pumping heavy crude oil and drilling mud
-
Resistant to the effects of corrosive and abrasive liquids.
-
Stable operation under high pressure.
4. Water supply and sanitation
-
Transport of concentrated sludge and industrial wastewater
-
Can operate in harsh conditions and aggressive environments.
5. Agricultural industry
-
Transport of liquid fertilizers, organic materials and animal feed.
-
Suitable for handling solid particles in liquids.

Important Tips for Using and Maintaining Single-Stage Pumps
-
It is very important to choose the right stator and rotor material depending on the type of fluid.
-
Dry running (without liquid) can cause serious damage to the stator.
-
Regular inspection and maintenance extend the life of your equipment.
-
Using the correct transmission system (transmission or direct clutch) will affect efficiency.
At last
The unique design and high liquid transfer performance of the mono pump have made it one of the most widely used pumps in various industries, from food and pharmaceutical to oil and water treatment.
If you need a pump that can withstand harsh conditions, provide stable flow, and convey thick liquids with solids, a single-stage pump is your best bet.
