Product Description:


It is suitable for offshore platform fire-fighting, thermal dissipation, seawater desalinization, seawater lifting, coastal square fountain, mariculture and attemperation as ground source heat pump in coastal area. It also can lift underground drinking water and mineral water,etc.


QH series stainless steel submersible pump has several kinds of material.

Seawater and strongly corrosive medium: austenitic stainless steel 316, 316L, tin bronze,etc.

Moderately corrosive medium: austenitic stainless steel 304,etc.


CNC lathe precision machining ensures parallelism and perpendicularity of all the castings.

With rigorous testing, well installation and full load performance test, you can feel easy to use it.

Some of our products manufactured by introducing the Germany Ritz technology, improving the pump’s efficiency and making it more energy-saving & environment-friendly.

Motor parameter:

The motor is accord with GB/T2818-2002 pump industry standard, and it is lubricated by water. The motor must be filled with water. The standard length of the extended cable is 3m.

If you need special requirement, we can extend its length. The working temperature should be a little higher than that of common motor because of its poor magnetic conductivity.


The general power specification we supply you:380v/50Hz±5. We also can provide customised specifications at your requirements. The variation of voltage and frequency ratings and its influence on motor performance and temperature should meet the requirements of GB755(National Standard)


We can provide you the suitable products if the actual working condition, the voltage or the frequency are not consistent with above specifications.

Working condition:

The motor should be submerged into water with the depth no more than 70m;

Water temperature: 20

Solid content (mass ratio): ≤0.01%

Q:how much do new brakes and a water pump cost?
New brakes are not a huge expense unless the discs need machining. Brakes should be done regularly as a part of on-going preventative maintenance. Water pump is not a big ticket item and is so easy to get at. Make sure you get a new gasket as well. Maybe $200 for brakes unless you know someone mech minded. $70-$80 for water pump plus fitting
Q:pulley on water pump has slight wobble. is it bearings going bad?
either the bearings are going out, or the pulley is bent. either way you should go ahead and change the water pump, they are cheap and if you wait it will be a problem later when you get stranded. good luck
Q:Does a water pump has to leakin to be bad?How can I tell if my water pump is workin?
Overheating normally would require a failed water pump. Some liquid leaking out of the weep hole normally just indicates that the pump is going to fail. Does the water pump make a clicking sound? An abnormal pump sound also is an indicator of a pump that is starting to fail. Verify that the coolant is full. If full, check the fan. If the fan is not turning on between 185 to 225, the temperature sensor may be bad. Also verify that the thermostat is installed in the correct direction. If installed backwards, the engine will overheat quickly. (This is an easy mistake.) Good luck!
Q:Water pump going bad?
Usually when a water pump goes bad,it either makes an obnoxious noise from bad bearings or you'll notice coolant seeping or dripping from the little weep hole on it.Seems like it didn't get flushed properly or the brown colored coolant you're noticing was there already before you done work on it.Pressure wash the engine to make things easier to see.Seems like the car would be overheating a little if the pump was completely gone out.Its a good idea to replace things like this on higher mileage cars to avoid bein stranded on the side of the road
Q:Labour involved in replacing a water pump?
Consult the Mitchells Manual
Q:how do i tell if my 1966 9.5 spotwin motors water pump is bad and how much water should come out when correct?
take it in.
Q:2004 Grand Am, water pump and thermostat?
The waterpump is very hard to get at to replace it. They do no thave to remove the engine, but they do have to remove a lot of the components to get to the waterpump. And it is a good idea to replace the thermostat while they have all the components removed. That way you can be sure that the thermostat will not be a problem later on. Especially now during winter. I think that is a fair price, unless you can get somebody else to do it other than a pro. It is worth saving your engine. If it gets hot, and you run it, your heads may become warped, your waterpump will give out and will cause much more damage. you will have to replace the pistons , rings, or probably the entire motor. good luck my friend.
Q:The reason why the pump is overloaded
(1) the influence of the basic installation on the equipment.The quality of equipment foundation installation has great influence on the quality of equipment operation. Iron pad placed properly, causing around the foot bolt hanging device, in alignment and fastening process for iron pad hanging, tighten anchor bolts will cause deformation of crosshead slide in the crankcase, the cross head is blocked in the operation of reciprocating load increases when the chute.W5 type reciprocating vacuum pump in the structural design of the cylinder body is cylinder, and the piston, intake and exhaust valve after the heavy weight in the foundation design without considering the cylinder support or hanger, the cylinder will be in a suspended state, because the weight of the crankcase cylinder will cause deformation of the cylinder and slide and slide the concentric degree of difference, so that the cross head is blocked in the slideway and the piston reciprocating operation is blocked during the reciprocating motion in the cylinder caused by the increase of the load.According to the above analysis, inspection found that the vacuum pump end of the cylinder body is slightly lower than the end of the crankcase, cylinder pad iron is low, deformation of crosshead guide foot bolts, the cross head caused by load increases in the slideway and the piston in the cylinder reciprocating operation is blocked, this is one of the reasons causing motor overheating.(2) cylinder and valve coking;The influence of process, cylinder and valve of reciprocating pump is easy to coke, Coke will cause the piston cylinder and piston in reciprocating cylinder operation when the load increases the valve is blocked; coking will cause poor exhaust, the valve closed lax, increasing load, low vacuum degree; clearance at the cylinder piston striking the cylinder will cause coke it will increase the load of cylinder, valve has found the phenomenon of coking, which is mainly caused by the low degree of vacuum.
Q:What's the best water pump to use for a portable mist machine?
I am assuming your water source will be the lake …. I would be looking at a submersible pump possibly a pond pump but you need to know what the “lift” is going to be …from the point where you string the mister to the pump {possibly a 15 foot lift} and a pump that will give you at least 25psi. Because you are going to have back pressure, the submersible will reduce the risk of burn out. Also you need to build a simple enclosed container this pump can sit in, with at least a 4”water inlet hole covered with mosquito netting, nylon hosiery, or something to filter the water….otherwise you will constantly be removing the mister heads to clean
Q:How much to replace a water pump on 2006 Mitsubishi Raider?
Have you asked the dealer to send you the part at least? Call Mitsubishi and ask it that would be possible, you never know. You could send in the old pump and possibly get compensation. Keep your bills. Discuss it with them. Your dealer should provide you with the area Mitsubishi representatives contact information. The prices for those can be expensive. Ask the dealer, service dept, for the labour, how many hrs. to change the pump. They should tell you. Also for the cost of the pump. Add the two together and you have your ans. Join CAA, or AAA, get a gold card, wait two days for the card's towing to take effect, then have it towed in on the card. Done all the time. Or if you have a relative with a Gold card they can have it towed in as long as they are with the car with their card when the tow truck comes.
