What is drive end and non drive end of pump?

Answer: The inboard side (non-drive end) bearing supports part of the radial load caused by the cantilevered impeller and is able to float axially to allow for thermal expansion of the shaft. The outboard side (drive end) bearing also supports the radial load, but it is fixed to keep axial shaft movement to a minimum.

How does pump motor work?

A pump is used to move fluids by using forces like air. Air moves forward from the way because the moving element starts to move. Generally, these are activated with electric motors that drive a compressor. Thus, a partial vacuum can be created because of the water movement, later it is filled with additional air.

What is rotor in centrifugal pump?

A centrifugal pump is a mechanical device designed to move a fluid by means of the transfer of rotational energy from one or more driven rotors, called impellers. Fluid enters the rapidly rotating impeller along its axis and is cast out by centrifugal force along its circumference through the impeller’s vane tips.

What prevents the impeller of a pump from turning on the shaft?

The shaft sleeve is used to position the impeller correctly on the shaft, and it also protects the shaft.

What is DE and NDE in pump?

ccw. DE – Drive End. NDE – Non Drive End. cw – clockwise.

What is the drive end?

the drive end (D.E., pulley end P.E.) etc. Base End of a Motor: The speed which a d-c motor develops at rated armature and field voltage with rated load applied.

What are the parts of pump?

The main components in a pump are the casing, impeller, backing plate, shaft and shaft seal, and the motor adapter. Some pumps have the backing plate as part of the casing in which case you would have a removable cover. The shaft seals are a critical part of the pump and selecting the right seal is an important step.

What is sleeve in pump?

A shaft sleeve acts as a shield for the shaft assembly in pumps and compressors. A shaft sleeve is a hollow metal tube, cylindrical in shape, which is mounted over a shaft and shaft assembly to protect it in a corrosive environment. Shaft sleeves are commonly found in single stage pumps.

What is impeller in pump?

An impeller is a rotating iron or steel disc with vanes in a centrifugal pump. Impellers transfer energy from the motor that drives the pump to the fluid being pumped by accelerating the fluid radially outwards from the centre of rotation.

What is the wet end of a pump?

Wet End Replacement – a wet end is the part of your spa pump that gets wet – the volute halves, and inside, the impeller and shaft seal. It’s sold as a complete unit, for quick field replacement, in the case of volute, impeller or seal failure.

What are the three main parts of a pump?

An impeller is a rotor used to increase the kinetic energy of the flow. Casing (Volute). The casing contains the liquid and acts as a pressure containment vessel that directs the liquid flow in and out of the centrifugal pump. The volute is a curved funnel that increases in area as it approaches the discharge port.
