What is a close coupled pump motor?
Close-Coupled Motor Mounting Close-coupled pumps use a single shaft that extends from the motor to the pump body through an opening in the cover plate. Typically the impeller is mounted directly to the motor shaft, but in some instances an adapter is utilized.
How does close coupled pump work?
How do they work? In a close coupled pump, the impeller is on the same shaft as the electric motor that drives the pump. The motor has a machined face on one end, which matches the face on the pump casing that is mounted against the motor face.
What is close coupled end suction pump?
In an end-suction close-coupled multi-stage pump, the liquid runs directly into the impeller and the inlet and outlet form a 90-degree angle to each other. The pumps typically produce high pressure relative to flow, making them ideal multi-purpose pumps for both industry and water boosting in general.
What does close coupled mean?
Close coupled toilets have the cistern attached to the toilet bowl, creating one streamlined unit which combines both essential parts. The pipes are hidden within the casings of the toilet and their compact nature means they are perfect for fitting into small or awkward spaces.
Why sleeve is used in shaft?
The shaft protecting sleeve is fitted to the shaft and rotates in the bearing bush. It protects the pump shaft against mechanical damage caused by shaft seals and bearing shells (see Plain bearing) and against chemical damage caused by aggressive fluids (see Material selection).
What is close coupled?
What is direct coupled pump?
If there’s a flexible coupling between the shaft and pump, it is called a direct coupled drive. This is one of the most common ways to drive a pump. It has most of the benefits of a direct drive, but eliminates the need for precise shaft alignment.
How motor and pump are coupled?
A pump coupling is the element used to connect the rotating pump shaft to the drive shaft of the motor; enabling the motor to efficiently transmit power to the pump. When a pump is close coupled, a separate coupling is not required as the motor is directly mounted to the pump on a single shaft.
How does a close coupled cistern work?
How does a close coupled toilet work? The toilet bowl and cistern are connected together allowing the water to evacuate from the cistern into the bowl using either a flush button or handle. Most models will have the option of either a 3 litre or 6 litre flush, which puts you in control of your home’s water consumption.
What is the difference between close coupled and back to wall toilets?
Close coupled – where the cistern sits directly on the back of the toilet pan. Back to wall – where the toilet pan fits against the wall or a piece of furniture and a concealed cistern provides the water for flushing.
