How to Choose a Water Pump

There are a lot of different factors you should consider when choosing the best water pump for your needs. Here are some of the most important factors.

Electric Water Pump

An electric-powered water pump is a good choice when you are using the pump inside. Typically, they will have 120 volts and can be plugged into a regular household outlet. For those that choose a 230-volt pump, you will need to have electrical wiring that can support it. While an electric water pump isn’t as powerful as a gas-powered model. However, they don’t require as much maintenance, so you won’t have to change the oil or perform any other upkeep.

Gas Water Pumps

A gas-powered water pump is typically found on a farm or at a jobsite. These pumps have powerful engines and can move up to 750 gallons of water a minute (GPM). When you have a situation, like a flooded basement, where you need to remove a lot of water, a gas water pump is perfect for the job. Just remember that a gas-powered pump will produce carbon monoxide and need to be used outside.

Use

You also need to think about how a water pump will be used. Since there are many different types of water pumps, you need to make sure the one you use can do the job. All water pumps are built to perform a special application:

  • Dewatering Pump – This pump will move clean water from one place to another
  • Trash Pumps – They quickly move large quantities of dirty water
  • Power Takeoff (PTO) Pumps – Tractors power these pumps
  • Submersible Utility Pumps – A versatile pump that can be used for different various water removal situations
  • Booster Pumps – They help to increase the pressure to water fixtures
  • Sprinkler Pumps – Used for watering farmland, lawns, or gardens
  • Well Pumps – Suitable for deep and shallow well systems in a home
  • Specialty Water Pumps – These pumps work with pool covers, sprinklers, fountains, and ponds

Important Ratings to Know

Suction Head (SH)

This is the vertical distance water is pumped from the source to the water pump. The higher that you want water to pump, the pump will have a harder time fighting gravity to do it. This is a particular important number for deep well projects or if you plan to drain a pond.

Total Head Lift (THL)

This number is the total height distance from your water source to the water’s final destination. With this number, you will know the estimated power of the pump to move water across a distance.

Gallons Per Minute (GPM)

This measurement tells you how many gallons of water the pump can move each minute.


Features to Look for When Buying A Water Pump

Flow rate

The flow rate tells you how much water a pump is able to pump over a specific amount of time. This rate is typically measured in liter per hours or minute. When you are pumping water at home, a smaller flow rate should be enough to fill your water tanks. Just remember that water usage in your home is typically on the low side.

Maximum head

The maximum head is referring to the vertical height the pump can push water with the necessary amount of pressure. If the pump has a head of 50 meters, it will not be able to pump water past 55-meters. So, it’s important to figure out the height that you will need water pushed and buy a pump that has a large maximum head to achieve the best water pumping efficiency.

Connecting hose size

A medium and small pump will come with an outlet hose and inlet that will range in size from one to six inches. It makes it easier if you match up the hose size with the size of the existing piping to ensure easy connections during installation.

Power

The power refers to the power and motor speed needed to operate the pump. When you use a motor driven pump, the pump’s power rating is very important. If you buy a smaller motor, it can underperform and use a lot more power, but it you buy a larger motor, it can overrun the pump diminishing the pumps life. It’s important to get a well-matched pump and motor to ensure that you pump will operate when you need it.


FAQs

What accessories do I need for my Water Pump?

When it comes to accessories, you have many accessories to choose from to make your water pump more versatile and useful. If you have a dewatering pump, you will need an inlet hose and a discharge hose as well as a strainer that keeps solid material out of the pump, or a hose kit if you have a gas water pump that lets you place the pump outside and use the strainer and suction hose remotely.

For water pumps that are used in a home including jet pumps, well pumps, and booster pumps, you should buy accessories including water alarms, float switches, and check valves. You may also want to buy a control box that gives you an electric plugin, a hydraulic power unit, and impellor it, and a replacement wheel kit to improve the pumps versatility and usefulness.

How do you choose an Inlet/Outlet size?

If you have a water pump that has different outlet and inlet size options, it’s important to know that no matter what the size, all of them work the same way. The water pump will suck in water through the inlet valve and expels it from the discharge valve. However, a three-inch water pump can potentially do the job faster than a one-inch pump. No matter what size inlet the pump has, you have use that sized suction or inlet hose. Remember that you never reduce the diameter of the suction or inlet hose.


Summary/Conclusion

If you have a situation where your basement floods a lot or you have a pond that needs to be drained, having a Generac Water Pump can be a handy tool. With the many types of water pumps that Generac makes, you want to make sure you buy the right type of pump for the needs that you have.
