Q:is sump pump water clean?
The only thing it would be suitable for is flushing toilets.
Q:What is the definition of the pump in the capacity of the pump?
I don't know very well about your work there;General pump is a one, or two with a preparation work; pump and standby pump capacity is big, the maintenance of pumps is provided here, said in the overhaul, overhaul maintenance enabled pump, pump capacity can be greatly reduced, as long as the pump 1/4, thus reducing the volume of the standby pump the.
Q:What size water pump do i need?
Like the last person, what you've looked at won't do much. Just think of a 5 gal bucket and how fast do you want to fill it up. Also you want pressure behind this water if you want to water with it, so look at the psi on a pump as well as the GMP to determine what will work best for you. I'd say 40psi should be enough pressure to run hoses and sprinklers and remember that the smaller the hose at the end gives the highest pressures. Hope this helps you out some. I'll admit, I'm thinking of this as knowledge of water pressures more than GMP, but I think I've explained something good about your question. Good LUCK
Q:what kind of water pump do I need to water my lawn? I would like to use water from my lake. 100 ft. downhill.?
Hey Guy, Get a Hayward Pump.. A solid Bronz.. Also, and this is important.. you can only pump water 14 feet in elavation.. You are going to have to put your pump down by the water and push the water up hill.. Do not cheat yourself... Get at least a 1 1/2 to 2 HP.. Anyting less will cost you more money. It will always be working under a strain. Make sure that the wires going to the pump are big enough to do the job.. You will need a 220 line. Sears also has some good pumps. Give me a shout at ... dvz_33 at Yahoo if I can help you any more. I used to have a pool and pump service.
Q:how to repair water pump?
All electrical things work on smoke - once the smoke escapes then they don't work. Seriously if water got into the works its probably burned out and needs to be replaced - having the motors rebuilt on these things usually costs more than a new one
Q:How can I test how high a water pump can pump to, using only pressure simulation?
Install a pressure gauge at the pumps diischarge line and note that p=wh. H =p/w, H =p{(144)/62.4}/3.28 meters Pressure expected therefore in psi, is p={62.4/144}3.28 p=14.9 psi A pressure gauge of 0 to 50 psig range would be sufficient to indicate the expected pressure.
Q:does coolant flow through the water pump?
Coolant flows thru, and sometimes is all coolant, very little water content.
Q:Installation position of check valve for water pump
Check valves must be installed at the pump's exit and position before the outlet control valve for servicing the check valve.Jiang Yuanyuan 1985's statement has a problem:1. On the flow of water, because the fluid is continuous and incompressible, the water in any part of the pipe will not flow as long as it is cut off in any position in the pipe.2, self suction exhaust is formed within the pump in outlet pipe, check valve installed in the inlet, because the pressure is low, is not conducive to automatically open the check valve, and its resistance, easy to form a vacuum pump and cavitation.
Q:water pump general question?
Yes it's possible one of the gaskets is bad,but if you're going thru the work of replacing the gasket you may as well replace the water pump,unless it's a new unit already
Q:How to rebiuld a water pump?
Dont waste your time rebuilding it, just buy one from napa or some auto parts place with a life time warrenty, on something like that your time is worth more then the water pump, and since the pump is having to deal with hot water and corrosion it's possible it might go out again soon or never but with the warrenty it wont hurt so bad.
