Different Types of Pumps

Pumps are essential tools used in various industries, including manufacturing, construction, and agriculture. They play a crucial role in moving liquids from one location to another, making them an integral part of many processes.

However, not all pumps are the same. Several types of pumps serve different purposes and have unique features. This blog will discuss the different types of pumps, their uses, and their benefits. By the end, you'll better understand which type of pump suits your specific needs and factors to consider when choosing one.

Pump Types and Examples

End Suction Pumps

Pumped liquid increases velocity as it moves along the impeller's vanes. Then, the liquid moves into the volute casing, where a diffusion process converts the high velocity to high pressure.  

ANSI Pumps

The only pumps in the US that are dimensionally standard as deemed by the American National Standards Institute.

Non-metallic (Lined and Sealed) Pumps

Withstand a wide range of severe service applications by being corrosion-resistant and abrasion-resistant.

Mag Drive Pumps T

Their primary feature is that the motor shaft does not extend into the interior pump, eliminating the need for a shaft seal that prevents leakage, lowering the maintenance cost.

Sump Pumps

Usually installed in sump pits, where water flows into the sump pit through drains or by natural migration through the soil.

Axial Flow Pumps

Consists of an axial impeller in a pipe that can be driven directly by a sealed motor.

Vertical Turbine Pumps

Designed to move water from a deep underground well.

Vane Pumps

Best at handling low-viscosity liquids. Have no internal metal-to-metal contact.

Pulp & Paper Process Pumps

Perfect for the pulp and paper industry, known for tough, abrasive processes.

API Process Pumps

Meets the American Petroleum Institute standard for pumps handling hydrocarbons.

Split Case Pumps

The casing is split into two separate chambers, which is less costly for high-flow applications.  Bearings on both sides can support the impeller.

Double Suction Pumps

Receive suction liquid on both sides of the impeller, which balances the thrust of the impeller.

Multi-Stage Pumps

Utilize multiple impeller and can be mounted on the same or different shafts.

Rotary Gear Pumps

Meshing of gears pumps the fluid through displacement. Example: +Viking Pumps

Centrifugal Pumps

Utilizes an impeller to move water and many other liquids.

Air-Powered Piston Pumps

Use high-pressure air to power or move the piston.

Abrasive Slurry Handling Pumps

Capable of handling high amounts of abrasive solids and mixtures.

Sanitary Pumps

Used to transport food and agriculture in operations that require cleanliness. Example: +Wrightflow Technologies

Self-Priming 

A type of centrifugal pump that uses an air-to-water mixture.

Air Operated Double Diaphragm (AODD)

Uses compressed air as a power source. Example: +Warren Rupp Sandpiper

Factors to Consider When Choosing a Pump

Selecting the right pump for your specific needs is a critical decision that can significantly impact your operations' efficiency and cost-effectiveness. Here are some essential factors to consider when choosing a pump:

1. Pump Type: As we've discussed, numerous types of pumps are designed for specific applications. Understand each pump's unique features, advantages, and disadvantages to identify the most suitable type for your needs.
2. Material Compatibility: The pump materials should be compatible with the pumped liquid to prevent corrosion and wear. Consider the liquid's properties, including its temperature, viscosity, and whether it contains abrasive or corrosive substances.
3. Flow Rate and Pressure: These are two of the most important factors. Your selected pump should be capable of achieving the desired flow rate and pressure to meet your system's requirements.
4. Energy Efficiency: Consider the pump's energy usage. More energy-efficient pumps can lower your operational costs in the long run.
5. Installation and Maintenance: Evaluate the ease of installation and the level of maintenance required. Some pumps might be cheaper upfront but could incur higher maintenance costs over their lifetime.
6. Reliability and Lifespan: The pump's reliability and expected lifespan are also vital considerations. Look for pumps from reputable manufacturers and read reviews to gauge their performance and durability.
7. Cost: Finally, consider the total cost of ownership, including the initial cost, installation, maintenance, and energy costs. The cheapest pump may not necessarily be the most cost-effective in the long term.

By considering these factors, you can make an informed decision, choosing a pump that fulfills your requirements, delivers optimal performance, and offers the best value.
