Product Description:

Specifications:

Perfect for caravans, boats, motorbikes, trucks and camping. Use it with fresh or salt water with your deck wash or to run your toilet or shower. These pumps automatically turn themselves on and off when you turn the tap on and off. Comes with filter and fittings. These pump are for intermittent use only.


A great pump for those country folk, with a small family, on tank water who only need to boost the pressure from a tank next to the house.


We have tested these pumps and found they will operate to a 2 metre suction lift and 5 metre head with no problems.


1.Maximum torque and operating efficiency/higher operating pressure and/or lower amperage than competitive pumps


2.Long life, no leaks, strong corrosion resistant


3.12/24 VDC and 115/220 VAC motors standard (consult factory for other voltages)


4.Quality components for extreme performance


5.Numerous fitting options for greater mounting flexibility


6.Voltage:12V/24V DC Diaphragm Pump,115V/230V AC Diaphragm pump


7. Expecially suitable for marine and recreation vehicle, such as boat and ship.Also suitable for Agriculture sprayer

How a Pump Works

The pump is driven by an AC or DC motor

In front of the motor is a valve assembly containing two to five valve pump chambers. Each valve chamber has a diaphragm behind it in the lower pump housing. As the motor shaft turns, an internal cam positioned behind the diaphragms causes the diaphragms to be pushed forward, then back in a continuous sequence creating a suction. As this suction builds, fluid is pulled hrough the inlet, through the various valve chamber check valves to the outlet he volume of flow is determined by several factors including: the number and size of the pump chambers,cam offset, operating pressure, fluid viscosity.

Q:How to connect the household pump capacitor?
1) in a line in the AC220V string into a large light bulb (Bai Chideng), and then the capacitor as shown in figure A, then, that B and C are three terminals; 2) the number of pump motor three lines 1, 2 and 3; 3) A, B, C and 1 2, 3, a total of six kinds of wiring combination: ABC/123, ABC/ 231, ABC/321, ABC213, ABC132 ABC312; 4) you have a a try, if you can turn up, and the fastest start wiring is correct, 5) if not turn up, you have to increase the number of watt bulb, such as 200 watts, 300 watts, 500 watts...... With a few 100 watt parallel one; 6) string into the bulb is designed to prevent the current is too large, it certainly must be removed after determining the connection method; 7) there is no suitable bulb that according to the motor power generation to choose the appropriate insurance.
Q:can i drive my car to a service center 5 miles with a blown water pump?
Probably not because most vehicles use a serpentine belt/drive belt to run the water pump and when the water pump goes the belt will most likely fall off. If you have an interference engine where the timing belt runs the water pump, then you could. It's not recommended, but I would do it if I couldn't do the repair myself.
Q:Relationship between pump voltage and lift?
In the case of power, W=F*S. That is, the work done per unit time pump = the gravity of the water flow * the displacement of the waterIt can be seen that:1, the power is certain, the head and the flow is inversely proportional.2, the greater the power, the greater the product of the head and flow.Therefore, when the flow is minimum, the pump head is the maximum; when the head is the minimum, the flow is the maximum.
Q:Why is the water pump smaller than the pipe diameter?
The size is only a matter of convenience or experience, and a small number of tubes are already available. As long as you can pick it up, you can use it.The so-called thick pipe to reduce resistance is a certain relationship. But it shouldn't be your decision to choose the big one. Then why don't you choose the big three? Four or the thicker ones?! @! The resistance will be smaller!!!!- - - - - - - - - - - - - - layman; look at the knowledge of fluid mechanics!!!The question is a conclusion, explain why not one or two words, learn the knowledge of fluid mechanics to know why -- try to answer it, that is to improve the water pump outlet total pressure head, intuitive feeling is to have enough pressure to pump out the water pressure. As for the big three or four, it is necessary to ensure that the flow velocity in the pipe is more uniform, otherwise the flow near the pipe wall will flow or flow too slowly due to viscous action.
Q:What all do I need to replace the timing belt and water pump?
You should be able to buy a timing belt kit. The kit usually includes a timing belt, tensioner, idler, balancer shaft belt(if applicable). Some even include the cam and crank seals. Water pump is usually sold separate. You should also get a head cover gasket and the spark plug tube seals since you have to pull the valve cover. Last thing would be drive belts since they come off as well to do the job depending on their condition. 1 gallon of coolant. As far as tools you'll need a 10mm,12mm,14mm,17mm and a 19mm wrench and sockets, wratchet, extensions, screw drivers etc... If your doing the job yourself the hardest part will be removing the crank bolt. A powerfull impact gun is needed or a special crank bolt removal tool used for Honda's. A manual to line up the belt and a floor jack and jack stand.One last thing if you do the job yourself, Be sure the marks are aligned properly because if not BAD THINGS will happen$$$$ Good luck and hope this helps.
Q:rv water pump?
A lot of the pumps for RVs do cause a slight sputter, Try compleatly filling the water tank, then turning the pump on,. Allow a few minutes to build up pressure and fill the hot water tank, If the sputtering slows, or compleatly stops, your ok. You have to remember that a lot of after market pumps don't work quite as well as an OEM pump. If it's a real bad sputtering, You might need to return the pump.
Q:Where should I buy my new water pump?
out of all the auto parts stores i use autozone is the cheapest but 45 miles away so i mainly use napa.
Q:Car water pump question!!!!!! HELP!!!!?
Well like someone else has mentioned the squealing usually comes from the round pulley that the belt rides on maybe in your case some metal has damaged the idler puller on your water pump and that would definitely give you a consent squeal. the price to replace your water pump is very excessive the part at any over the counter parts store ranges from 30-45 dollars the labor too do this on a jeep is 2.2 hrs @ the shops hourly rate which also varies but 45-55 hour isn't unreasonable... so on the high side of these figures it should be about 120.00labor 45.00 parts so a bill of $165.00 would be more appropriate......but if you don't make the repairs knowing it still has a problem you might void any type of repair warranty on your current repairs already completed...hopefully this has helped you somewhat...jimboz
Q:Changing a water pump in a pt crusier?
The water pump is driven by the timing belt on this motor. If it is not done right, you could cause serious damage to the engine. Actually $800 to change the pump and timing belt is reasonable. To lower the price further you could negotiate buying your own parts. Good luck.
Q:1994 Toyota Corolla strange noise...Is it the water pump again?
