As a rule of thumb, the clearance should be between 0.5% and 1.5% of the impeller diameter. Balance the impeller: To ensure smooth running and prevent vibration, the impeller must be balanced. A balanced impeller reduces wear and tear on the bearings, seals, and other components of the pump.

Perhaps the best way to visualize water hammer is to start with a hypothetical example. Figure 1 below shows a pump pumping water into a pipe that was empty when the pump started. The two valves, located at the pump discharge and the far end of the pipe, are fully open and have the ability to close instantaneously.

By: Mueller. Water hammer (or hydraulic shock) is the momentary increase in pressure inside a pipe caused by a sudden change of direction or velocity of the liquid in the pipe. Water hammer can be particularly dangerous because the increase in pressure can be severe enough to rupture a pipe or cause damage to adjoining flow control …

A. Water hammer is also known as surge pressures or hydraulic shock. It is a condition that exists when fluid changes velocity quickly in a piping system. There are several causes of water hammer, but most often in pumping systems it is due to a pump start or stop, a rapid change of valve position, or a valve failure.

Whilst they are able to handle a degree of solid content unlike closed impellers, they require a higher NPSH to operate without cavitation, damage and loss of efficiency. 2. Semi-open impeller. Semi-open impellers have a back-wall shroud that adds mechanical strength to the vanes, whilst remaining open on the other side.

Figure 3: Swing Check Valve. In certain applications, providing additional rotating inertia to a pump can slow its rate of deceleration when power is cut off (Figure 4). This allows more time for flow-control devices to mitigate water hammer effects, reducing the risk of damaging backflow through the pump and water hammer effects on the system.

The main function of an impeller is to transfer energy from the motor. The motor drives the pump to the fluid being pumped. This is achieved by rotating the impeller at high speeds. This creates a centrifugal force that moves the fluid outwards from the center of the impeller and into the pump's discharge.

Valve Closure and Opening. One of the primary causes of water hammer is the abrupt closure of a valve. Figure 1 shows a main pipeline with a branch circuit that is fed by a "Tee." At the end of the branch is a valve. The black arrows show the flow direction in the primary and branch lines, and the blue arrow is the length of the branch line.
