Sealing strictly Low noise split case centrifugal pump

How pumping system design affects sealing performance Double-ended split-case pumps. Operating on the same centrifugal principle, but slightly different geometry, are double-ended split-case pumps (Figure 5). Fluid enters both ends of the pump and is directed into the eye of an impeller, which spins it out of the volute to discharge.

Pros & Cons of Horizontal Split-Case Pumps Pumps & Systems It is the best of pumps; it is the worst of pumps. Horizontal split-case (HSC) pumps are used in most industries around the world to move large quantities of fairly clean fluids—usually water—at low to medium pressures. HSC design geometry poses numerous advantages and disadvantages for users. Advantages of HSC pumps:

Cavitation - centrifugal pump Cavitation noise and erosion damage Q - We have five, single stage, double suction, axial-split, horizontal pumps in raw water service. When we run three pumps in parallel they operate smoothly. But when we run four units, to get slightly more flow and head, they make loud cavitation noise. We disassembled one pump and found that:

PACO Horizontal Split Case Pumps: KP Grundfos The PACO KP/KPV split case pump is a single-stage, non-self-priming, between bearing, centrifugal volute pump. The axially split design allows easy removal of the top casing and access to the pump components (bearings, wear rings, impeller, and shaft seal) without disturbing the motor or pipe work.

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.

Pump Bearings & Shaft Seals Boost Performance Pumps Bearings in centrifugal pumps support hydraulic loads imposed on the impeller, the mass of the impeller and shaft, and loads caused by couplings and drive systems. They also keep axial and radial shaft deflections within acceptable limits for the impeller and shaft seal. Handling all these functions—often in difficult process conditions—bearings are subjected to adverse forces that
