Centrifugal Pumps for Electric Motors - John Blue

Centrifugal Pumps for Electric Motors. Patented Vac-U-Seal impeller design creates a vacuum between the impeller and mechanical seal. Lack of pressure on the seal face minimizes seal wear and results in a longer seal life. Double wet seal design provides for continuous lubrication of the seal faces. This wet seal design allows the pump to be ...

Understanding Centrifugal Pump and Motor Torque-Speed Curves

08-10-2019 · The torque-speed curve is similar for all centrifugal pumps due to simple math: the pump torque varies as the square of its speed. However, when the pump is at rest—0% full load speed—the full load torque is never also 0%. Starting a rotating pump requires the motor to overcome the pump inertia and static friction.

What is Centrifugal Pump - Definition - Thermal Engineering

22-05-2019 · Centrifugal pumps are devices that are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an electric motor or steam turbine (in case of turbine-driven feedwater pumps). Centrifugal pumps are used in more industrial applications than any other kind of

06-05-2018 · Replacement motors. When replacing a centrifugal pump motor, it is important to select one that has the same voltage and service factor. This is especially true in the case of small single phase motors where the service factor may be quite large. For example, a typical 3/4HP jet pump with a 1.45 service factor actually has almost 1.1HP available.

How to Size an Electric Motor for Use with a Centrifugal Pump

So if the pump power requirements indicate that the motor should be rated for at least 4.5 HP, you’ll have to round up to the next normal motor rating: 5 HP. While you don’t want to undersize and electric motor, the vast majority of motors are designed with a 1.15 service factor which will provide a bit of an insurance policy.

Operating a Centrifugal Pump with a Variable Frequency ...

Operating a Centrifugal Pump with a Variable Frequency Drive. It is increasingly common for pumps to be operated by motors that are controlled by variable frequency drives (VFDs). VFDs control motor speed by varying the frequency of the power being sent to the motor. So a 60 Hz motor operating at 1800 RPM will reduce to 1500 RPM if the ...

What is a Centrifugal Pump | Intro to Pumps

A centrifugal pump is a machine that uses rotation to impart velocity to a liquid, it then converts that velocity into flow. Centrifugal pumps are made up of two primary components: an impeller and a casing. The rotating impeller generates velocity and the casing converts velocity into flow.

Electric motor | KSB

The electric motor is an electromechanical energy converter/drive that converts electrical into mechanical energy. Direct current motors, alternating current motors or three-phase motors are used, depending on what type of electrical energy is available. This energy is typically converted into rotational movement. The electric motor does the opposite of the generator.
