Hp-500 Cast For Drain Plugs?

Recommended Posts

It looks like the HP-500 pumps from Keene are made to drill and tap for drain plugs.  image.thumb.jpeg.85d8c3cdb822fb4fef632796cb6fdc1b.jpeg

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.

      All the bad weather, snow and to many things I need to take care of no chance to get away for a trip to gold country, been watching tons of YouTube gold related videos on prospecting related stuff and the occasional Jeep roll over compilation just to scare me into not doing that stuff with my Jeep on the gold trail😲. Lots of ideas on the web for idle hands to foolishly venture, not that I don’t have anything to occupy my time, but a little sucking device somehow seemed like a good idea, so off I go... I’ve been building my little Jeep friendly recirculating sluice and thought I would try making a nozzle for use with the pump I already own, just a few pipe fittings and a little part here and there. I already have a Keene high banker setup and 90gpm Honda pump I can’t use in California, but something small for Jeep travel where it’s ok might come in handy, so I build the first one paying attention to everything I can think of to reduce friction and any head pressure and the little bilge pump was inadequate for the task.  

      searching the web for 12v pumps it’s hard to find anything that produces both volume and pressure at a reasonable price, the rule 4000 utility pump was the most powerful at 66gpm open flow and max lift of approx 30’ with over half its rated volume at 15’, but at a cost of 20amp hrs power consumption, they even made a two stage model rated at 134gpm same rated lift. Only problem the rule evacuator pump line are discontinued and I could only find one seller in the US that still had 3 in stock, every one else was out and the product is no longer listed one the manufacturers web site. I passed on the rule4000 and found a reasonable priced 1000 gph utility pump with a rated max lift of 7m out of Korea and ordered one, it won’t arrive until sometime in April I find out so we’ll see but I suspect it was a waste.

      I should have stopped reading about water pumps, but didn’t and found another 12v pump that looked better with more volume than my bilge pump or the Korean pump and with a rated max lift of 7m burning only 13amp hr from my battery and ordered it.

      superior pump came today and I outfitted my nozzle with the new pump along with a water proof power switch and cigarette lighter socket power cord, even with the power of this pump (1/4hp) the suction is inhibited by the discharge restriction and lift enough to make it not quite just enough suction to be practical, however pumping directly into a container without the lift it will suck dirt and gravel more than enough to be worth trying out for bedrock cracks. Everything but the battery weighs 8# total out of the water and in the water it’s slightly negative buoyancy keeps it on the bottom without feeling heavy it also feels fairly well balanced.

      Before the superior pump arrived eBay kept nagging me about the rule4000 and I still couldn’t find a replacement for this now discontinued pump, so with only the 3 left I figured it was only a couple hundred and I’d might regret it more later if I passed cause I’m on a mission now and pulled the trigger on the rule pump, estimate it arrives on Friday. At over twice the power and capacity of the superior 12v pump it should pump material into my little highbanker if I get a larger battery.

      Anyway more to come...

      Before I waste my money,does anybody know if I can add a 2.5 inch Proline swivel nozzle to a 2.5 inch Keene suction nozzle? Maybe cut off the angled end of the swivel nozzle and then weld to the intake end of the suction nozzle, sure would make the hose easier to handle I would think? how does the swivel joint work anyway? I prefer the suction nozzle in shallow creeks  to avoid losing my prime.

      Hi All, I have a 2" Keene dredge and a 3" Keene HighBaker, I use the 2" 90% of the time cause the 3" high banker about to much for me to get to the small creek I go to. I get very small gold at this creek but a lot of it. Do you think if I fit the 3" sluice box on my 2" floats I can get better gold recovery?  I never run my Honda full blast anyway. I was just thinking the bigger sluice will keep more small gold. What do you all think?  Thanks   Dean
