Open impellers allow pumping of liquids with particles up to 80/90ml, that’s about the size of a tennis ball. Although we don’t actually pump tennis balls, we do have Open Impeller Pumps in use at McCains for pumping waste water and starch with potato
Open impellers are usually used in small, inexpensive pumps or pumps handling abrasive liquids or suspended solids (in which the impeller rotates between two side plates, between the casing walls of the volute, or between the stuffing box head and the suction head). The clearance between the impeller vanes and the sidewalls allows for some water slippage (similar to slip in a reciprocating ...

17/12/2011 The pump performance and efficiency of an open-faced impeller continues to decrease as the impeller and the pump casing begin to wear. The performance and efficiency of an open-faced impeller is a function of the clearance between the impeller face and the suction volute or plate. A five point reduction in performance on a pump that is operating at 50 percent efficiency will translate into a ...
18/07/2018 Applications: Open impellers usually are used in small type pumps and handle suspended solids and less to clog. Or where particle blockage may be a problem or where the shear provided by an open impeller is an aid to pumping froth. Semi-open Impeller. Features: Semi-open impellers only have a back wall that adds strength to the impeller.
Read on to find out which impeller will be best for your centrifugal pump application. Open Impeller. An open impeller has vanes that are attached to a center hub and mounted directly onto a shaft. There is no wall surrounding the vanes which makes open impellers weaker than closed or semi-closed valves. Open impellers are generally faster and easier to clean and repair. Open impellers are ...
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).

The open impeller design allows liquids containing relatively high levels of impurities to be pumped without the risk of the impeller clogging. As a result of these characteristics the NGA series pumps are used specifically in industry and for transferring water from canals, rivers, reservoirs, tanks, etc.
By fitting the vane ends very close to the pump casing, the open impeller is able to prevent large amounts of fluid or gas from recirculating back through the eye. A major drawback to open impellers results from the tight vane/casing tolerances required to maintain efficiency. As temperature increases, shafts are known to increase in diameter as well as length (approximately 0.001 inches both ...
When buying a centrifugal pump, we always look for pumps with high efficiency, minimal maintenance and good reliability. One must always consider all these factors, however, one thing that people forget to look at is the selecting the right impell...

With the open screw or single sealed impeller the suction stream ahead of the impeller and the design of the inlet blade profile deliver very low suction pressures so high flow rates can be achieved at high pump speeds and high temperatures. Furthermore, because there is limited fluid contact with the impeller, shear rates are low and free passage of solids and slurries is achieved. These all ...
