Things you should consider before buying a water transfer pump
Choosing the right water pump can be rather challenging as we mentioned earlier on, especially when you do not know what to look for. Below are five things you need to look at when choosing the best water pump.
1. Type of pump
Water transfer pumps come in several types namely: electric, engine-powered, diaphragm, and jet pumps. Depending on the exact function you want the water transfer pump to do, you will need to pick the most suitable pump. Diaphragm pumps, for example, are more suited for pumping thicker fluids like sewage or mud while jet pumps are generally used for pumping water from deep sources. You need to do extensive research on all the different types of water transfer pumps before picking any one particular type. Also, consider whether the pump will be used for different pumps purposes or one dedicated purpose.
Water transfer pumps should ideally be lightweight. This will help you easily move them around especially when you are not using them for just one function. Heavy pumps which require assistance to move around are not recommended. Water transfer pump should weigh 14 pounds or below to ensure you can comfortably lift and move around. Weight is pretty important especially when the pump is bought for household use and not commercial use. Household use usually means that you will be constantly doing the work alone with no assistance.
When you want to go for the best water transfer pumps, you must consider the size. They should be small enough in size to help with portability and easy storage. You don’t want a large pump that is hard to move around especially in your home. Also, you probably don’t have enough space to store a large pump your entire lifetime. Ensure that you look for a pump with a lot of functionality and power but it should be small in size. You may need to move the pump to your basement in case of flooding and this can be quite challenging should the pump be large.
4. Water moving capabilities
When it comes to water transfer pumps, you need to critically consider the water moving capabilities. This entails looking at the following key aspects
- Maximum head
This generally refers to the maximum distance that the pump can move water vertically. The maximum head will, therefore, be an indication of the uplift and suction height of your water transfer pump. You will need to ensure you get a pump which is capable to move the water to the required point.
- Flow rate
Most of the time, the flow rate is expressed as L/Min (liters per minute) and shows the amount of water that a particular pump can transfer in a minute. The basis of a water transfer pump is to transfer water and this means that you should ensure you look for one with a high flow rate.
- Water pressure
You should look for a water transfer pump with high water pressure capabilities. The water pressure determines how far your pump will be able to move water which is quite important. Ensure you do extensive research on the water pressure capabilities of the water transfer pump you are considering to buy before actually purchasing it.
5. Quality and reliability
You must go for quality before looking at the price. Quality can easily be determined by looking at two important aspects.
- Manufacturing material
The type of material the transfer water pump is made out of and the different components need to be durable too. There are a lot of affordable water transfer pumps in the current market but most are made from poor quality material which will not last. Yes, you could buy cheap, but you will back in the market shopping for another one within a short period.
Quality and reliable water transfer pumps tend to have a relatively long warranty duration. Long-period warranties are a sign that the manufacturer of a particular product is satisfied with the creation of the product and confident in its functionality.
Best Water Transfer Pumps Buyer’s Guide
What causes water pressure?
Essentially resistance to flow is what causes water pressure. When a force tries to transfer water and a resistance to that movement happens, then the water is said to become pressurized. For example, when water flows from a garden hose it usually comes out in large quantities but no force. However, should you place your thumb on the end and only allow a small gap, then water shoots out with incredible force and travels a longer distance.
When should one replace the gasket?
Gaskets should be replaced every time you remove them during servicing. The gaskets are pretty cheap and it should therefore not be a problem to replace them. A faulty gasket can be rather annoying because they cause pump leaks which greatly interferes with the water pressure and transfer rate. When servicing your water transfer pump, it is important to replace the gaskets. Most of the pumps come with additional gaskets.
Are all water transfer pumps self-priming?
Most water transfer pumps need to be primed whenever they lose pressure. However, the priming process is quite simple and you could always do it by yourself. Some pumps only require a tablespoon of vegetable oil for the priming process and instructions are always written down in the manual. Some water transfer pumps are self-priming and you will not need to prime them every time. Ensure you carefully read the manual to determine whether your pump is self-priming or not.
Is it bad to run the water transfer pumps dry?
You should never run your water transfer pump dry. Remember that the impeller and pump shaft usually run at fast speeds. When there is no water, then the rotational speed will turn to heat which can permanently damage important components of your water transfer pump such as the motor. Running your pump dry will greatly reduce its service life and you will find yourself shopping for a new pump soon.
How often should I grease the water transfer pump bearings?
The water pump bearings must be properly greased to ensure you reduce damage to your pump and increase its servicing time. Now, some water transfer pumps have bearings that are pre-greased to last a lifetime and these models do not require any greasing. However, other models require greasing and this should be done every 250 hours of service. You could grease the bearings by hand or use an auto greaser. Ensure you read the instruction manual to determine whether your bearings need greasing or not.
My pump has become noisier. What is the problem?
When you note that your pump is making louder noises during operation than it did before, then there is some damage. It is difficult to determine the exact problem with the water transfer pump until you have it disassembled. Now, you must seek the help of a professional to disassemble your pump and inspect for any damages. Doing it by yourself is rather difficult and you will probably not be able to diagnose the exact problem.
In as much this article is about my top five picks of the best water transfer pumps, there has to be one that stands out from all the rest. In my opinion, the Wayne PC4 ½ HP Cast Iron Multi-purpose water transfer pump is the most ideal water pump when it comes to moving water from one point to another.
Compared to the other equally good water transfer pumps, it pumps out more gallons of water per hour and is quite heavy-duty. With a line pressure of 40 PSI, it can move water long distances and it is more heavy-duty than the rest.
Looking at things to consider when looking for a water transfer pump, it checks out all the boxes. It has a high water moving capability, relatively low weight making it portable, it is small in size and saves a lot of space, made from quality durable material, and is multi-purpose thereby ensuring you can use it for several tasks.
