How to Hook Up a Centrifugal Booster Pump to a Water Tank

Home » How to Hook Up a Centrifugal Booster Pump to a Water Tank

A centrifugal booster pump is one of the most valuable accessories that you can add to your water tank. Whether being used with a rainwater harvesting pump or a storage tank for the residence, the hydraulically operated machines increase the water pressure with significant results.

Once your water tank is supported by a booster pump, the harvested rainwater can be used for a wide range of processes such as watering the garden or flushing the toilet. In turn, you will save money while simultaneously creating a greener home.

First and foremost, you must purchase a quality centrifugal booster pump that will deliver a robust and reliable performance for many years. To gain the best results from your booster pump, however, a smooth installation will be necessary. This quick guide will teach you how.

This guide will answer the following questions:

What Will You Need to Hook Up a Centrifugal Booster Pump to a Water Tank?

When choosing a centrifugal pump, it’s important to make the right selection between a single-stage end suction and dual-stage end suction unit. Likewise, the kW level should be aligned to your intended usage as the difference between a 0.37kW booster pump and a 2.2kW unit, for example, are significant. The motor speeds, operating pressure, and ambient temperature are just three factors that may vary.

If you are unsure about which centrifugal booster pump is right, an AQS Liquid Transfer technician can guide you through the process. As well as the booster pump itself, you will need:

When you have the right kit to connect your booster pump to a tank, you will also need to check that you are close enough to a power socket. You will also need a flow control switch to start the pump when taps are opened and stop the pump when there is no flow.

How to Install a Centrifugal Booster Pump

Before you begin the installation process, it is important to know that some minor contrasts may be seen from one model to the next. Nevertheless, the fundamental procedure will include the following steps:

Step 1: Connect the Ball Valve to the Water Tank

Take the ball valve from the connector kit and wrap some sealant tape around the reducing bush in a clockwise direction until the whole of its surface has been covered. Following this, you will be able to screw the valve into the water storage tank, once again using a clockwise turn. The outlet should be located at the bottom of the tank.

Once tightened, you will want to ensure that the tap of the valve is straight and facing upwards.

Step 2: Connect the 1″ Ball Valve to the Flow Controller

Using a similar process as step one, you will need to wrap some thread sealant tape around the flow controller’s outlet until the surface is fully covered. Next, you can connect the 1″ ball valve using a clockwise turn and ensure that the tap valve is straight and facing upwards.

Step 3: Connect the CAM Fitting

Take the male CAM fitting and wrap it with thread sealant tape. It can then be connected to the inlet of the rainwater pump using a clockwise turn. The CAM fitting should stick out from the pump, almost parallel to the ball valve from the flow controller.

The CAM fitting should then be tightened by using the water pump pliers. Tighten until it cannot turn any more.

Step 4: Connect the Suction Hose

The suction hose found from the pump connector kit can be fitted to the CAM fitting lock that is now on the centrifugal booster pump and fixed in place using the arms to tighten it. Most suction hose kits will have two of them to ensure a tight fitting.

Next, the other end of the suction hose should be fitted to the ball valve that is connected to the water storage tank. Again, the hose can be secured in place using the two arms. By now, you should have a clear connection (the hose) between the water tank and the booster pump.

Step 5: Connect Pipework to Flow Controller

The pipework may vary slightly from one application to another but the next step is to connect it to the flow controller. After wrapping the thread sealant tape around the end of the pipework, it should be secured into the flow controller via the outlet of the ball valve.

Step 6: Get the Water Ready to Flow

Using the flare screwdriver, you can unscrew the bleeding screw that’s facing upwards on top of the pump unit until water begins to flow freely. Once this happens, you may close and tighten the bleeding screw.

Step 7: Start the Centrifugal Booster Pump

Between the casing and the back plate or under the impeller, you will find the o-ring. Remove it by pulling it over the top of the impeller and then clean with the cloth, removing any dirt. Also clean the locating face, removing any loose material or debris.

Step 8: Enjoy

With the centrifugal booster pump now connected to the water storage tank and applicator, it can be used for the garden, washing machine, toilet, and a host of other features. The additional power offered by the unit should ensure that the application performs as desired time and time again.

Conclusion

As long as the right products are selected, adding a booster pump to a tank isn’t an overly time-consuming task. However, it’s imperative that you complete the installation process accurately. Otherwise, the pressure-boosting capabilities will be significantly reduced while replacements could be needed far sooner.
