things like what type of equipment do you have the gph running through it gold size in your area etc… are important. example: i have a keene highbanker- 10″ wide 48″ long running a 2″ trash pump rated at 8000 gph but i measured it and the actual gph going through the sluice is 6000 gph. most of the gold is in the 50 – 100 mesh
jun 13 2017· how do i choose a tank for my system? i’m going to show you how easy it is to size a pressure tank.choosing the proper tank for your pumping system will greatly reduce the risk of premature pump

a highbanker is basically a sluice box with mobility and added height. it is mounted on a 4-legged stand that gives the sluice box the correct slope. instead of being put right in the creek like a sluice an engine with a water pump and some hoses transports the water up from the stream into the highbanker. highbankers are also called power
good quality 1.5″ smaller… pump powers: raptor flare – mini. click the pic for price. this is a great 1.5″ pump that delivers 57 psi and about 6000 gph. it also cuts about 25 pounds off traditional water pumps. like all high pressure pumps you need to put a fine screen over the intake. high pressure pumps do not like sand and gravel.
mar 04 2013· what size motor and pump are you running. is the pump a keene type pressure pump or a trash type pump. and what size is your pressure hose to the suction head. i see you have a blaster nozzle in use. is that to supply water for dry land dredging cant quite make out whether it is hand held or attached to your suction head.
bilge pump capacity: do the math. by beth a. leonard. just how much water can your bilge pump move? probably a lot less than you think. click image to enlarge. if you have any boat larger than a small runabout chances are you have an electric bilge pump somewhere aboard.
this week i went and asked “how to size a sluice box” to the crew on a large gold prospector forum and other sluice or gravity gold recovery ‘experts’ and gathered the list of emails and forum posts here below. as you will see in summary most can optimize or troubleshoot a sluice box but few or none can size a gold sluice …
a recirculating sluice box for gold prospecting: one of my many hobbies is recreational gold prospecting. i've been gold panning on my vacations for many years. it's a lot of fun. it's great exercise. i get to do it in really scenic locations. i have even found some gold. however you aren't lik
however not only does this lead to higher operating costs but you may also be overpowering your filter system. as a general rule you should have a pump that filters all the water in a pool in an eight-hour period. this page will show you how to select a pump that filters all the water in your pool in eight hours.
here is a shot of the lower end of the sluice with the water flowing. for this test run i put the bilge pump in the bottom of the bucket and only filled it about with about 3 gallons of water. i just wanted to test everything without filling the tub up with water. in actual use this system will need about 8 gallons of water …
mar 24 2012· thanks for the info i have a keene a52 sluice i believe is 10 by 48. i would like the pump to be 12volt so i could set it up in the desert. sawmill is your 2200 gph johnson pump 12volt and also wouldn't it be easier to buy a smaller pump than having to put a valve in to divert excess water or do you do it that way in your using it as a highbanker and need the extra power for pumping the
jun 13 2018· a sluice box works because gold is 15 times heavier than sand and gravel and so is easily trapped by the riffles and carpet in the sluice box. dredges almost always need to be mounted on a set of floats. this is because a dredge has just enough power to lift water and gravel to just above the surface of the water.
sizing storage and heat pump (with tank) water heaters. to properly size a storage water heater for your home -- including a heat pump water heater with a tank -- use the water heater's first hour rating. the first hour rating is the number of gallons of hot water the heater can supply per hour (starting with a tank full of hot water).
jan 10 2014· tankless water heaters are rated by the maximum temperature rise possible at a given flow rate. therefore to size a demand water heater you need to determine the flow rate and the temperature rise you’ll need for its application (whole house or a remote application such as just a bathroom) in your home.
as a general rule the optimum slope-setting of a sluice is around one inch of drop per linear foot of box. this can change depending upon the volume and velocity of water being used and/or the average shape size volume or weight (specific gravity) of material that you are processing.
finally once you figure out the size you need and are shopping for your pump you will likely encounter the term "lift." this refers to the height that the sump water must be pumped before leaving the house. for example many basements are 7 feet tall plus 2 feet into the sump pit for a total of 9 feet of lift.
i have an a-51 sluice and its been a while but at 2000 or 3000 gph. there was only enough force to run expanded metal. water was just not deep enough and strong enough to push material over the riffles with the battery operated pump. the battery had enough power to run a very small recirculating sluice…

mine is a johnson 2200 gph bilge pump that pulls 8 amps at 12 volts what size panel will i need and what do they cost? can i run the output strht to the water pump or do i need a controller thing? or can i use a panel to recharge my 12 volt 15 amp gel cell and how long will it take? thanks. -tom v.
aug 14 2016· this is quite important as working with a pump will mean that you have power the pump so that it can supply the water to your recirculating sluice box. to turn your sluice box into a recirculating sluice you will need to build a cradle to hold the sluice box over a tub.
can you use a trash pump with a dredge? the moving flow of water from the pump creates a lower pressure at the intersection in the pipe. the moving water is at a lower pressure which makes the slower moving water (higher pressure) want to move towards the water.
