Basic Differences Between Open and Closed Impellers in

In an open impeller, no pump disassembling is necessary. An open impeller is less likely to get clogged and even if it does, it is easier to clean whereas in a closed impeller, if stringy material or solids are pumped, the impeller can clog and it becomes really difficult to clean them.

Selecting the correct sewage pump impeller - Pump Industry

The semi-open impeller, due to its lack of a front shroud, also tends to create greater unbalanced axial forces than does the closed impeller. Both pump out vanes and balance holes are often utilised to minimise these forces and prevent potential bearing damage. Although the radial flow impeller is the workhorse of the sewage pump industry, there are applications for which it is not well-suited. One

Closed single-vane impellers are used to pump fluids containing very coarse solids. They are characterised by a non-clogging free passage. The drawback of these impellers is the so-called hydraulic unbalance due to the asymmetrical pressure field. See Fig. 7 Impeller. Open channel or single-vane impellers are used to handle gaseous liquids.

Vortex impeller

A whirlpool is a funnel shaped opening is created downward from the water surface. It can be developed by water flowing out of a small opening in the bottom of a basin, a reservoir or by a pump. Impellers creating this Vortex are called vortex impellers. The benefit of a vortex impeller over a channel impeller is the minimised risk of clogging.

Useful information on centrifugal pumps

The impeller is the key component of a centrifugal pump. It consists of a series of curved vanes. These are normally sandwiched between two discs (an enclosed impeller). For fluids with entrained solids, an open or semi-open impeller (backed by a single disc) is preferred (Figure 1).
