Product details

This is the Pentair high head impeller for 10 horsepower commercial pool pumps, single phase or three phase. The source lists the part as 73830 and also refers to it as 073830, which is the same impeller written with and without the leading zero.

High head, not standard

At any given horsepower a pump can be built with more than one impeller. The high head version trades some volume for pressure, so it keeps working against long pipe runs, deep filtration and the head that commercial systems carry. Fitting the wrong curve gives you a pump that runs but never reaches the numbers the system was designed around.

When to replace it

Impellers wear from the inside out. Sand and grit round off the vane edges and open the clearance between the impeller and the diffuser, and flow falls away year by year. Because it happens gradually and the pump keeps sounding healthy, it usually gets blamed on the filter first.

It is listed with the Pentair R Series commercial pump parts covering 5 to 15 HP and with the Purex Pentair C Series commercial pump parts. Confirm the horsepower and the head rating on your pump before ordering.

Questions and answers

What people ask about this product, answered by our pool techs.

Is the part number 73830 or 073830?
Both appear in the source: the part is listed as 73830 and referenced as 073830. It is the same impeller, written with and without a leading zero.
What does high head mean?
It is a different impeller profile for the same motor. A high head impeller trades some flow for the ability to push against higher system resistance, which is what commercial installations with long runs and heavy filtration need.
Which pumps does it fit?
It is listed under the Pentair R Series commercial pump parts for 5 to 15 HP and the Purex Pentair C Series commercial pump parts, in the 10 HP size.
How do I know my impeller is worn?
Falling flow with a clean filter and clear baskets is the usual sign. Grit and cavitation wear the vane edges and open up the clearance, and the pump loses output steadily without ever sounding wrong.
