Electric Centrifugal Water Pump Water pumps are machines that propel the movement or circulation of water. To perform the task it is designed to do, these devices expend energy derived from electricity or from solar power. There are different types of pumps among which is the centrifugal pump. The DH1.0 is an example of a centrifugal pump. It encourages water flow through the rotational energy emanating from the motor to hydrodynamic energy as the fluid enters the rotor and exits from the pump casing. A single-speed, or single-stage pump, comprises of a single rotor. This type of pump is one of the best options for a whirlpool bath or hot tub because of its ability to generate a high water flow rate. A water pump can also be cost-efficient. A one horsepower pump coupled with a 0.5 horsepower air pump will consume about 1.12 kW. - We provide a huge selection of Water Pumps. Centrifugal Pump Problems The DH1.0, being a centrifugal pump, is not immune to issues such as impeller damage, leaks, overheating, power surges, and corrosion. Impeller damage can be due to hydraulic wear. Plus, dross accumulated on it will hinder water flow. Leaks can happen around the pump’s rotating shaft. Low water flow will beget overheating. The circuit breaker has a possibility to trip if there is a short in the pump’s wiring. And corrosion of the pump internals will occur if the pH level of the water is too high or too low and the bearing of dissolved oxygen is high. - You can send us a message if you need assistance to ensure you are buying the correct water pump for your hot tub, whirlpool bath, or spa system. Tips: Choosing and Caring for Your Hot Tub Water Pump A water circulation pump can have an output of 3/4 HP to as high as 5 HP. It can run on 220-240V or 110-120V. Most pumps have a label attached to its body where technical specifications can be found. Checking this is vital for selecting which replacement pump goes with your tub. Another thing to consider when buying a water pump is the size of the frame. Pumps come in either a 56 frame or a 48 frame size. The reason for this is the bolt holes on the pump must be contingent to the holes inside the tub or spa system. Information on the frame size can also be found on the label. It is worth mentioning that water must not get into the pump’s motor. If it does, it will permanently damage the pump.
