	Trimming the impeller
		Gap "B" describes the clearance between the impeller vanes and the casing or volute.
		There is increased turbulence at the vane tips as the impeller is trimmed because the shroud to casing clearance (Gap "A") is increasing.
		For impeller diameters up to 14 inches (355 mm) gap "B" should be at least 4% of the impeller diameter to prevent "Vane passing syndrome cavitation" problems.

	Mixers - Impeller Technology - HAYWARD GORDON :: Pumps - Mixers - Strainers - Engineered Systems & Controls
		This impeller is useful on taller tank applications because it can invest the same or greater torque into a fluid at lower speeds than an AL impeller, normally allowing longer shaft lengths.
		The impeller of choice when both flow velocity and fluid shear is required and/or when very high mixing intensity is required when the use of a hydrofoil would result in too high a tip speed or operating speed.
		This impeller is similar to the Rushton turbine except curved blades are substituted for the vertical flat blades resulting in a lower power number.

	Pac 21 - Impeller Packer (Site not responding. Last check: 2007-11-04)
		Impeller Hopper is of unique design employing a four vane rotary impeller running within a 10 inch diameter circular casing.
		The impeller is fed from the top segment of the casing from sloped infeed hopper sides which load the impeller as it roates.
		The impeller is shaft mounted from one side using a bearing casing to ensure proper alignment.

	Smart Turner Pumps: Open & Enclosed Impeller End Suction
		Impellers require no field adjustment of running clearances which are factory set during assembly to ensure optimum efficiency and hydraulic performance. The heavy section of the impeller provides
		Impeller: Cast in one piece, the impeller is trimmed to the exact diameter required for the service rating and then factory balanced to ensure smooth, vibration free operation.
		Impellers are hydraulically balanced and have precise radial clearance between them and the casings resulting in lower circulation and wear, and minimal increase of stuffing box pressure.

	Impeller
		If the impeller is too big you may be disappointed and discover you have worked hard and spent lots of cash to end up with little or no RPM gain or even lost RPM's.
		Using the same impeller you will either gain 500 RPM and be off the cam curve or you can switch to a larger trim impeller to absorb the additional SHP at about the same RPM as before.
		The alternative solution is to leave the impeller the same, change the cam and valve train to be more effective at higher RPM's and get a gross power gain which is the sum of the nitrous added power and effect of the stronger cam.

	Unsteady Simulations of Impeller-Diffuser Interactions in a Centrifugal Pump
		The middle stage is composed of an impeller having 7 blades and a diffuser having 13 vanes (Fig.
		This comparison invalidates the assumption that the insensitivity of the diffuser to the pulsating flow leaving the impeller, is due to the rapid mixing of the flow in the vaneless gap in front of the diffuser.
		The comparison of the unsteady signals obtained from the stator-rotor simulation with simulations of the impeller and diffuser coupled with unsteady boundary conditions, showed that in the impeller the two signals agree well when the time-averaged flow is used to prescribe the boundary condition at the outlet of the impeller.

	Anco Mixers - Impeller Selection
		This impeller uses four vertical blades that are formed in a curved or swept design.
		This impeller is the standard 45 degree pitch blade workhorse that has four (4) blades attached to a hub and pumps either downward or upward in an axial direction.
		It is a midrange design between the axial mix and high efficiency axial impeller types so that a large impeller can be used in a flocculation basin yielding good pumping characteristics while imparting the required power with lower tip speeds than typically required by the flocculation process.

	Technical Info - Impeller Basics (Site not responding. Last check: 2007-11-04)
		When watercraft and impeller manufactures design an impeller, their goal is to reach the absolute best overall performance and efficiency possible for the range of PWC pumps that the impeller applies to, and provide you with both bottom-end and top speed without having to compromise.
		Using the impeller that was designed for sea level performance restricts the motor, because the lack of oxygen to your engine will not allow it to run at it's peak performance combined with the sea level impeller.
		If you examine a progressive pitch impeller from the side, you will see the pitch angle of the blade is constant where it is attached to the hub, but the outer edges of the blade are not.

		The recommended impeller is determined to be an improvement when directly compared to the performance of the stock impeller.
		Also, when we develop an impeller design that is more efficient than the original impeller, we offer a variety of choice's to accommodate the many different variables that are usually present like, rider weight, altitude, motor modifications, and the riders performance desires.
		In the case that the impeller is not deemed a performance gain, but simply equal in performance to the original impeller, the customer would be informed of this prior to the purchase.

	Replacing a Cooling Pump Impeller by Don Casey
		Rubber impellers pass twigs and pebbles and small pilchards, but stop the flow of water to them and they shed blades like leaves in an October storm.
		Most just slide over splines, a keyway, or flats on the shaft, but impellers are occasionally pinned to the shaft with a through-bolt or set screw.
		If the impeller is missing vanes, be sure you can account for all the pieces.

		A pulley mounted on the outside of the supercharger spins the gears within the supercharger, which then spin the impeller (the turbine's fan).
		The supercharger pulley is usually spun by the engine's serpentine belt, although some superchargers use a dedicated second belt, a cog belt, or a chain.
		The sound of an internally gear driven supercharger is unmistakeable and plays a great part in the psychological warfare involved in racing.
