A liquid pump is a device that moves liquid from one area to another. While most people buy liquid transfer pumps to move water from one location to another, other types, models, and sizes of pumps are available. You can use liquid transfer pumps for different reasons, such as removing flood water from the basement, draining a swimming pool, or irrigating crops in your garden. Ideally, you should buy a pump that’s suitable for your kind of task.  

Due to the variety of pumps in the market, you need to consider your specific needs when choosing a liquid transfer pump. Different pumps serve different purposes. There are many types of this liquid transfer pumps, and they are divided into five main categories, as follows:

  • Lightweight Pump 

A lightweight pump is designed to offer a high-pressure liquid transfer. It is compact, portable, and versatile. This type of pump is ideal for sprinklers, irrigation, and pumping liquids long distances.  

  •  General Purpose Pump 

A general pump can tackle most liquid transfer situations. Though the pump is lightweight, it has a full-size engine. These pump types have several adapter options, such as garden hoses, tubes, and other adapters.   

  • Clean Water Pump 

A clean water pump only transfers water without heavy debris. It is best for lawn irrigation or water transfer from small ponds and hot tubs.    

  •  Trash Pump 

A trash pump handles wastewater, but the water should not be more than two inches. They also work best at a lower pressure level. This pump is perfect for commercial and agricultural use, including draining a small flooded area, irrigating big fields, and draining water on construction sites.   

  •  Semi-Solid Pump 

This pump is not very different from a transfer pumper. The main difference is that a semi-solid pump can transfer water with some solid particles and debris. It can handle solids with sizes ranging from .25 to .75 inches. It is an excellent choice for emptying a swimming pool and removing water from flooded areas of your home, such as the basement.  

 Factors To Consider When Choosing A Liquid Transfer Pump

 1. Flow Rate 

The flow rate refers to the particular amount of water transferred per minute. It is measured in liters transferred per minute. If you are looking for a pump to move water to a big farm, construction site, or industrial use, make sure it can handle more than 2500 liters per minute. A water pump for domestic use should have a rate ranging from 100 to 200 liters per minute.   

 2. Operating Temperature 

Transfer pumps are designed to withstand various temperature ranges. So, if you’re looking to transfer hot liquids, ensure the pump can handle over 200°F or the maximum temperature of the liquid you want to move.    

 3. Vapor Pressure 

A pump that suits your liquid’s vapor pressure reduces cavitation risk. Vapor pressure refers to the force per unit area exerted by the fluid when converting it into vapor. Make sure you buy a pump that can handle the vapor released by the type of liquid you want to transfer.  

 4. Fluid 

Fuels and chemicals can damage your pump if not built to handle such liquids. You should find a pump designed to pump corrosive liquids and can take slurry water and debris without getting degraded or clogged. Manufacturers usually rate how much and the size of fragments a pump can handle. Aside from that, know the liquid’s viscosity so you can buy a pump with enough power or draw the liquid for easy transfer.   

 5. Maximum Head 

Considering the maximum head, you can tell the longest distance and highest height a pump can move any liquid. For example, a pump to move water as high as 82 feet should have a maximum head of about 98.4 feet.  

 6. Size Of The Inlet Valve 

The inlet valve is the point where a water pump sucks in liquid. On average, most pumps have an inlet valve ranging from one to six inches. The larger the inlet valve, the more water is sucked in. you can always talk to an expert to help you choose the best pump, depending on your needs. 


Always take your time to learn about different pumps to select the most ideal for your needs, and save money since you won’t need to go back for another pump. At the same time, consider buying your pump from a company with a reputation for stocking high-quality pumps and equipment. Such a supplier might provide post-purchase services like installation and maintenance that goes a long way in ensuring your pump remains in good condition for a long time.
