Hp-500 Cast For Drain Plugs?

[Bear]

It looks like the HP-500 pumps from Keene are made to drill and tap for drain plugs.

I showed the top of the pump because on Keene's websight there is a picture where a pump is drilled and tapped with a pressure gage in it.

You are right, looks like they planned for a drain, etc. Good job Keene!

Why wasn't it tapped it and plugged when Keene built it?

I think I've had Keene pumps that were drilled and tapped?

I have not seen any that came from Keene drilled and tapped. I drilled and tapped a P180 before.  I was a little worried because the petcock didn't have a lot to grab on to.  This nub allowed me to cut a lot of threads.

Because "most" dredgers are fair weather dredgers.. you really only need a drain if you're going to be in freezing weather.  It's easy enough to do it yourself but big kudo's to Keene for putting a little more in the correct spot for the drain.

A little inside fyi.. Keene pumps might start coming with the intakes on the pump threaded so you can screw the intake hose on, that way you won't get any air.
