For an expanding volute pump where the impeller centerline is offset from the casing centerline (i.e., noncongruent), the clearance between the outer diameter (OD) of the impeller (D 2 dimension) and the cutwater is a critical design parameter. The clearance is also referred to as the radial gap.
Centrifugal pumps are essential equipment in various industries, used to move fluids through a system by converting rotational kinetic energy into hydrodynamic energy. However, one common issue that can arise with centrifugal pumps is the occurrence of high pitched noise, which can be indicative of underlying problems within the pump system.

Noise in Pump Head
One of the main sources of high pitched noise in a centrifugal pump is cavitation in the pump head. Cavitation occurs when the pressure at the inlet of the pump drops below the vapor pressure of the liquid being pumped, causing the formation and collapse of vapor bubbles. This phenomenon generates high frequency noise, often described as a high pitched squealing or whining sound.
Noise in Pump
In addition to cavitation, high pitched noise in a centrifugal pump can also be caused by issues such as misalignment of pump components, worn bearings, or excessive vibration. These mechanical problems can lead to increased friction and turbulence within the pump, resulting in noisy operation.
Flow Pump Noise
The flow rate of a centrifugal pump can also impact the noise levels produced. High flow rates can create turbulent flow conditions, increasing the likelihood of cavitation and noise generation. Properly sizing the pump for the intended application and ensuring smooth, laminar flow can help reduce noise levels.
Air Pump Noise Problems
Air entrainment in the pump system can contribute to high pitched noise. Air bubbles passing through the pump impeller can cause vibrations and turbulence, leading to noisy operation. Proper priming and venting of the pump system can help minimize air entrainment and reduce noise levels.
Steam Pump Noise
In applications where high temperature fluids are being pumped, steam formation within the pump can also lead to noise issues. The rapid expansion and collapse of steam bubbles can create high pitched sounds, indicating potential overheating or cavitation problems. Proper insulation and cooling measures should be implemented to prevent steam-related noise.
Noise in Pump Valve
Faulty or improperly functioning pump valves can also contribute to high pitched noise in a centrifugal pump. Valve flutter, leakage, or obstruction can disrupt the flow of fluid through the pump, causing turbulence and noise. Regular maintenance and inspection of pump valves are essential to prevent noise-related issues.
Noise in Water Pump
When cavitation occurs in a pump or valve the level of noise produced is considerably more pronounced. Cavitation noise typically sounds like a high-pitched crackling and transitions to …
The volute of a centrifugal pump is the casing that receives the fluid being pumped by the impeller, maintaining the velocity of the fluid through to the diffuser. As liquid exits the impeller it has high kinetic energy and the volute directs this flow through to the discharge. . If the pump flow is higher than design the velocity will .
