Types of pumps

There are many types of pumps, but which one is suitable for your business?

A thorough inspection of the types of pumps and accurate cognition will help eliminate damages to other machines caused by incorrect choice of pump and also increases the useful life of the pump. This is a collection of the most popular and practical pumps that are divided into two categories: centrifugal pumps and positive displacement pumps.

 

A) Centrifugal pumps

Centrifugal pump is a common name for pumps that consist of one or more impellers.

Because of high flow rates these are very suitable for transporting liquids with low viscosity or concentration.

The flow rate of these pumps: 5 to 200,000 (grams per hour).

The pressure of these pumps: 10 to 7500 feet or 3 to 2286 meters.

The power range of these: 0.125 to 5000 hp.

B) Pumps with positive displacement

A wide range of pumps are included in the set of positive displacement pumps. These types of pumps do not have impellers and are composed of alternative parts that trap liquid or gas in a chamber and when they reach a certain pressure, they are taken out of the chamber.

These types of pumps are for high viscosity liquids and liquids containing solids, including brittle solids.

The flow rate of these pumps: the range of 0.1 to 15000 (grams per hour).

The pressure in these pumps: the range of 10 to 100 psi.

The power range of these pumps: 0.5 to 5000 hp.

The pressure: 10 to 200 feet or 4 to 87 PSI.

The power: 0.25 to 250 hp.

 

Barrel pump or drum

Drum pump is usually a small pump to drain low liquids. This pump is known as a centrifugal pump, but its larger dimensions are also a kind of positive displacement pump for moving high viscosity liquids. This pump is mostly used for corrosive substances.

The flow rate : of 0.05 to 70 GPM or 2 to 265 glasses.

The pressure : 20 to 75 feet or 9 to 33 PSI.

The power : 0.25 to 1 hp.

Grader pumps

This pump is a kind of submersible / Floating pump. One of the most common uses of this type of pump is to open residential sewer pipes.

The flow rate : 5 to 50 (minutes per hour).

The pressure : 5 to 150 feet or 22 to 65 PSI.

The power range : 0.5 to 5 hp.

 

 

Fire pump

Another type of centrifugal pump is the fire pump, which is used only to pump water. These pumps are used for constructions, plants and other environments.

The flow rate : 20 to 5000 (grams per hour) or 76 to 18927 glasses.

The pressure : 100 to 1200 footballers.

The power : 10 to 800 hp.

 

Domestic pit pump

This pump is used for vertical turbines and in domestic wells.

The flow rate : 4 to 265 liters per hour.

The pressure : 20 to 200 feet.

The power : 0.5 to 5 hp.

Processor pumps

This pump is another example of a pump that is located at the top of the tanks and is used to suck liquids into the tanks. Such as water or oil.

The flow : 5 to 700 (rpm)

The pressure : 10 to 350 feet
