Product Description:


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:What are the ways of hydraulic pumps?
Check valves, such as single piston pumps, three piston pumps, etc.;The port of the valve arrangement, such as the radial piston pump.
Q:What does electromechanical vector pump mean?
Scope of application is;Residents living water: such as high-rise buildings, residential areas, villas and so onPublic places such as hospitals, schools, gymnasiums, golf courses, airports, etc
Q:Direct connection pump What is straight pump and non direct pump? What's the difference in structure?
What is straight pump and non direct pump? Direct coupled pump shaft and the motor shaft is directly coupled with the coupling and non direct coupled pump: pump shaft and motor shaft through the belt pulley, V-belt connection or other forms of transmission. What is the difference in the structure: the direct coupled pump has the advantages of compact structure, simple installation, but the relatively small power; non direct coupled pump: pump and motor is independent, the two transfer torque through the belt, the structure is relatively large, complex installation, general power is relatively large.
Q:Is the diaphragm pump and the drain pump one?
First of all, there's something wrong with your concept.Diaphragm pump is in accordance with the way the pump classification, drain pump is in accordance with the use of pumps classification.
Q:Roots pump and dry pumpRecently, the work involved in the vacuum pump, do not understand this, is a ads602 vacuum pump
Here the roots pump and dry pump must be used, because the roots pump is not used alone, and must be a stage vacuum pump (pre vacuum pump can be dry pump, water ring vacuum pump and rotary vane vacuum pump can be, you here with dry pump series)
Q:How to select the fire pump?
Modify the part: (the design of regional common fire pump should be in accordance with the requirements of the original design, building design) contains a 55m high building, and the basement is about 6m, the pump reached in the basement height about 61m (common fire pump should be based on the highest floor of other low floor area, low ring and take in this case, relief measures) 61 levels, the most unfavorable hydrant to reach 0.07MPa (maximum allowable 0.5MPa) plus loss of lift at least about 90m more appropriate, of course can be higher to take relief measures (120 too high), the basic flow of lossless (with the same time there is only one building fire) according to the maximum amount of a building fire water pump set can be, there must be a backup with a preparation, and then select the appropriate pump manufacturer specification query.(the 20 houses on 99m are only shared with a 135m pump)
Q:Why can the centrifugal pump hold down the pressure?
The pump before starting to pump shell and the water pipe filled with water, and then start the motor, the pump shaft to drive the impeller and water do high-speed rotation, centrifugal water movement, was thrown to the outer edge of the impeller, the pressure water pipeline flow through the volute pump into the pump shell.
Q:What are the meanings of the vacuum pump, the front pump and the main pump?
The main pump and the front pump with the general vacuum unitThe front pump can be understood as a mechanical pump. It can be used by itself, but the pumping rate or the vacuum can not meet the requirements. In this case, we add a booster pump
Q:What are the uses and precautions of magnetic pumps?
2, when the suction surface above the pump axis, before starting the valve can open the suction pipe, if the aspiration level below the pump axis, the pipeline to be equipped with bottom valve;3, the pump should be checked before use, the motor blade rotation to be flexible, no jam, no abnormal sound, the fasteners should be tightened;4 、 check whether the motor rotation direction is consistent with the magnetic pump steering mark;
Q:What is the principle of a turbopump?
A machine that converts the energy contained in a fluid medium into mechanical work [turbine]. Also known as turbines, turbines. Turbine is the transliteration of English turbine, derived from the Latin word "turbo", meaning "rotating object". The working conditions of turbines are different from those of the employed ones, so their structure types are various, but the basic working principle is similar. The most important component of a turbine is a rotating element (rotor or impeller) that is mounted on a turbine shaft and has blades uniformly arranged along the circumference. The energy of the fluid is converted into kinetic energy in the flow through the nozzle, and when the fluid passes through the rotor, the fluid impacts the blade and drives the rotor to rotate, thus driving the turbine shaft to rotate. The turbine shaft drives the other machinery directly or through the transmission mechanism, and outputs mechanical work. According to the turbine working fluid used can be divided into different turbine (used as a power source of Hydropower Station) and steam turbine (used in thermal power plant, ship propulsion), gas turbine (used as jet propulsion, ship power, and power plants, with a small peak load power station and air turbine (only) as a small power).
