How to Look for the Perfect 12 v Diesel Transfer Pump?

Before anything else, we need to give out a clear definition of what a 12 v diesel transfer pump is. When you have a good idea of what its intended purposes are, there is a good chance you will see if you need to have this piece of equipment for a project or not. 

As its name suggests, the main purpose of a diesel transfer pump is to transport water, or any kind of liquid for that matter, from one region to another. Such activities may include moving liquid, water as usual, from a dam to individual tanks. Or it could be out of your basement, or from an area in your construction site to another place.  

This also explains the reason why water transfer pumps became known to many of us as a dewatering pump. It significantly helps in eliminating water from a particular area. And it is useful most especially if that region is susceptible to flooding. By using diesel transfer pumps, the likelihood of flooding to occur can be alleviated. 

The market today is highly saturated with a wide array of water transfer pumps, thus, we have a lot to choose from whenever we have a need for one. But we must know what we are going to look for before we start shopping. If we do so, there is no way we can get the wrong kind of water transfer pump for your project.  

We are presenting below our no-fuss guide to finding the right 12 v Diesel Transfer Pump to buy! 

Select the size of the inlet/outlet

With regard to the application, water transfer pumps are available in a wide range of sizes. Like for instance, a lightweight pump is intended for use in the garden, around the home, and also for boating while the larger sized pump is ideal when you need to pump huge volumes of liquids to fill up dams or site flooding and anything similar.  

No matter what size you pick, you can expect that diesel transfer pumps will work in pretty much the same way. The liquid will get suctioned in via an inlet valve and eventually eject through the discharge valve. The manner in which how fast it gets the job done is what makes the difference.  

The speed of the liquid transfer would be depending upon the suction and discharge ports sizes, which is the inlet and the outlet. Normally their range is from 1 up to 4 inches. We reckon that a 4-inch port will be capable of moving water at least 4 times faster compared to a 1-inch port.  

Choose Flow Rate

It is typical for 12v diesel transfer pumps to have a low PSI capacity as opposed to a high-pressure fire water pump, yet powerful enough to carry large volumes of water. You can measure this up by the liter/minute flow rate. The amount of flow rate that you will require here will depend upon the task size at hand.

Like for instance, in a small domestic job, this would probably require 100 -200 liters for every minute of flow rate. A commercial task or a much larger property would be requiring 10 times that flow rate. 

We need to take into account the flow rate together with the pump’s “Maximum Head” capability. This pertains to the maximum distance or height which the pump can pump to.

So this means to say that if you have a pump having 60 meters maximum head, you can anticipate a flow rate of zero at 60 meters. Therefore, it is safe to conclude that the flow rate will wane with the height or distance.  

Choose Your Engine Type

Consider the type of engine that you will need to have for your pump, should it be petrol, electrical or diesel-powered? The majority of the structural designs for electric water transfer pumps are intended for indoor smaller requirements. They cater to the various needs of a DIY user for their smaller domestic tasks. Most of the time they are less powerful and thus would be needing less maintenance as opposed to a diesel or petrol pump.  

Take in Account Their Design Features

What will you need a water transfer pump for? Water transfer pumps that are intended for commercial would usually come with specially designed features, primarily for use around a worksite. Here are some of the important things you will want to look for:

  • Anti-vibration dampening helps secure your pump in place and alleviates noisy rattling while the pump is in use.
  • Rollover casing gives protection to your water pump in case that it is knocked. 
  • Portability, allows you to move about your water transfer pump around your boat or garden.  
  • Low oil shutoff, allows for automatic stopping of the engine the moment that it is running short on oil — a mechanism to help it prevent damage on itself.
