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:Rotary vacuum pump does not meet the requirements of vacuum, what are the reasons?
1) oil rotary vane vacuum pump is too low, no effect on the oil seal exhaust valve, rotary plug to refuel after large exhaust sound, and oil mist, that the level is too low, the gas can be eliminated.(2) the vacuum caused by the condensable steam pollution of oil should be changed, and new vacuum pump oil should be replaced.
Q:What's the word "pump"? Is that what advocates mean?RT
The words should be decided by the object that everyone supports. The supporters are called "fans"; those who support the singers are called "fans"; the people who support "stars" are called "fans". If the idol supported by everybody is called "shadow" and "view",Star of song? It can not be called "what fans", can only be called "fans"!
Q:Why do we need to stop the pump?
The valve opening pump is aimed at the centrifugal pump.From the power curve of the centrifugal pump, the power of the centrifugal pump increases with the increase of the flow rate; the flow curve of the centrifugal pump shows that the flow rate of the centrifugal pump decreases with the increase of the head.
Q:What is the main difference between SK water ring vacuum pump and 2BV water ring vacuum pump?
The unified corrosion resistant design of bronze impeller improves the corrosion resistance of the pump, and the stainless steel material is more suitable for more severe applications;
Q:What are the characteristics of the piston pump?
1 、 built in overvoltage protection and flow correction system.6 、 large screen LCD display.7. The well designed exhaust device can effectively remove the bubbles in the liquid.8, flow and pressure settings can be memory, and PLC communication (custom).
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:How to distinguish the flow and displacement in the hydraulic pump? What's the difference between the two?
For example, once you sprinkle water from the tank to the ground, one shot of water is 1000 milliliters, which is equivalent to displacement, once (pump turn) 1000 ml.,
Q:Any center of the pump
Looking forAlignment means the position of the center of rotation of the pump and motor so that they are in the same line.At least three times after the initial installation or after installation:
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 are the basic technical parameters of the pump?
The effective power of pump and output power, with Pe said. It is the effective energy per unit time from the pump in conveying out liquid obtained in the pump. Because the lift refers to the effective energy, pump output unit of heavy liquid obtained from the pump so that the product of head and the mass flow rate and the acceleration of gravity. Is to obtain the output from the pump in unit time of liquid effective energy - efficient pump power: Pe= P gQH (W) = QH (W) - P - density of liquid pumping (kg/m3); severe gamma - pump for transporting liquid (N/m3) - Q (pump flow; m3/s; H) - pump head (m); G (m/s2). The acceleration of gravity P axle power and effective power Pe is the difference of power loss in the pump, the size of the pump efficiency to measure the efficiency of the pump. As the effective power and shaft power ratio, with ETA said. Selection of related pumps:
