Positive Displacement Pumps Similar With Viking Pump

A positive displacement pump is a pump that delivers fluid by periodically changing the volume of the pump chamber.

Its working principle is to change the volume of the pump chamber through mechanical movement, thereby sucking in and discharging fluid.

The characteristic of a positive displacement pump is that the flow rate is proportional to the rotational speed, it can generate high pressure, and is suitable for transporting fluids with high viscosity or that require precise metering.

Gear pump: The volume of the pump chamber is changed by the rotation of the gear.

                     It has a simple structure and is suitable for transporting high-viscosity fluids.

Features of positive displacement pumps:
1. Stable flow: The flow rate is proportional to the rotation speed, suitable for accurate measurement.
2. High pressure output: can produce higher pressure, suitable for high pressure working conditions.
3. Strong self-priming ability: It has good self-priming ability and is suitable for transporting high-viscosity fluids.
4. Complex structure: Compared with centrifugal pumps, it has a more complex structure and higher maintenance requirements.

Application Areas

1. Fine Chemicals & Petrochemicals: Precise addition of catalysts, additives, pigments, etc.

2. Pharmaceuticals & Biotechnology: Precise delivery of pharmaceutical solutions, culture media, etc.

3. Food & Beverages: Quantitative filling of jams, chocolates, etc., and ingredient addition.

4. Water Treatment: Addition of flocculants, disinfectants, etc.

5. Inks & Coatings: Ingredient mixing and quantitative delivery of color pastes, etc.

6. Electronics & Semiconductors: Delivery of high-purity chemicals, photoresists, etc.

FAQ

1. Q: Can it transport water?

A: Gear pumps are generally not recommended for transporting water. Gear pumps rely on lubricating fluids, and media lacking lubrication, such as water, will cause accelerated gear wear, affecting pump performance and lifespan.

2. Q: Can it reverse?

A: Gear metering pumps can be operated in both forward and reverse directions.

3. Q: Does it have self-priming capability?

A: Gear pumps do not have self-priming capability.

4. Q: Can it be run dry?

A: Gear pumps should not be run dry for extended periods. Gear pumps rely on liquid for lubrication and cooling of internal components, such as gears and bearings. Dry operation will increase friction and temperature, potentially damaging pump components.

5. Q: What is the viscosity range it can handle?

A: Different models of gear pumps can handle different viscosity ranges. Generally, gear pumps can handle liquids with viscosities up to 10,000,000 cps, exhibiting good performance in transporting high-viscosity liquids.
