Domestic Water Pumps Types

Low water pressure, excessive water in the house, or sudden coldness in hot showers all indicate a malfunction in the water supply system. When you start to encounter such problems at home, it may be time to replace the pump unit. There are many different types of domestic pumping devices. Below are four different water pumps that help maintain an efficient and reliable water supply system for your home. So after reading this article you will hopefully have a better understanding of domestic water pump types. Let's go!

Four types of Domestic Water Pumps for Your Home

Submersible Pumps

Submersible pumps are water pumps located underground. They are designed to push fluid to the ground, not to push fluid to the house like a jet pump. Our technicians only use first-class pumps from manufacturers such as Gould, Sta-Rite, and Grundfos. A submersible pump is a device with a sealed motor that is completely submerged in water, especially an open hole and wellbore. They are an effective and wise choice because they are already immersed in water, so no primer is required. They are divided into two types:

Sump Pumps

These types of pumps are specifically used in basements and crawl spaces. They are ideal for houses located in low-lying areas and vulnerable to flooding. The sewage pump pumps out the excess water that has accumulated in the basement or under the house. The sump pump automatically pumps water out of the sump through a drain pipe and away from the house, thereby preventing flooding and water damage. If your sewage pump fails in heavy rain, the basement may flood quickly, damaging your belongings, causing you headaches, and paying the cost of cleaning up the flood.

Jet Pumps

Jet pumps are mainly used in shallow wells because they can only be installed 25 feet above the ground. They draw water from the well by using the suction force caused by atmospheric pressure. The jet pump is installed inside the house or above the well in a separate well room. The most common pump in shallow wells for domestic use is the so-called jet pump. The jet pump is a domestic water pump type that is installed above the well, whether at home or in the well room and sucks water out of the well by suction. Because it involves suction, atmospheric pressure is what matters. Think of the system as a long straw. When pipetting, a vacuum is created in the pipette above the water. Once the vacuum is reached, the weight of the air or atmospheric pressure pushes the water onto the straw. Therefore, the height at which water can be lifted using a shallow well jet pump is related to the weight of the air.

Constant Pressure Pumps Types for Domestic Applications

Have you experienced periods of low water pressure at home or are you unable to wash clothes while running the dishwasher at the same time? For these types of low water conditions, the constant pressure pump is an exception. They will help you control the water pressure and provide the family with healthy tap water pressure. Constant pressure pumps provide standardized water pressure in the home or company. The constant pressure controller uses the new technologies to produce constant water pressure by variable speed modulation of the submersible well pump.


How to Choose the Right Type of Domestic Water Pump?

There are a few factors that you need to consider when selecting the right pump for your domestic water pumping applications. Let’s take a closer look at some of them:

Flow Rate

Typically, this is the impact of the domestic water pump. Flow rate refers to the time the pump takes to move a given volume of water, typically in liters per minute. If you want to use a water pump on a work site or field, you can purchase a pump that can pump more than 2500 liters of water per minute. On the other side, pumps with a flow rate of between 100 and 200 liters per minute are ideal for any household use.

Size of the Inlet

The inlet size of most pumps is between 1 and 6 inches, but in some cases, it may be larger. Centrifugal water pumps often operate similarly, i.e., they suck in water from the inlet of the river and then discharge it through the outlet valve. In this case, the larger the size of the inlet valve, the more water the pump will be able to pump, and the faster it will work.

Maximum Head and Pressure

The maximum lift of a water pump refers to the longest distance the pump can pump water. For example, if you buy a pump with a maximum head of 60 meters, if you try to pump the pump to a water level higher than that height, the flow will be zero. Generally, the maximum head of the pump you choose should be higher than the height you plan to pump.


A Few Words on Booster Pumps

The booster pump is a domestic water pump type that is considered an auxiliary pump used to increase or maintain the pressure in the drinking water system. They are most commonly used in systems with inconsistent water requirements. When the demand is low, a booster pump automatically switches to standby mode.

When the demand is high, the booster pump will start and maintain the necessary water pressure to meet the increased demand. The booster system usually includes one or more pumps, tanks, and control devices. They are designed to maintain adequate water pressure in low-pressure areas, "middle-rise" structures, "high-rise" structures, and facilities where water demand varies greatly.

When the water rate increases and/or the water supply pressure drops below an acceptable level, the booster system starts to work. Circulating pumps are used in piping systems to circulate special liquids, liquefied gases, and drinking water. Circulating pumps are usually centrifugal pumps, but turbopumps are also included.
