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:What's the difference between a concrete pump and a concrete pump truck?
Concrete pump and concrete pump truck are concrete conveying machinery, use the same, but the former need to transport and car towing need additional support pipeline, the locomotive body and arm extends freely, without pipeline, hundreds of thousands of millions of the former, the latter
Q:The suction pump has a nominal suction range of 30 metersHow deep can a well be sucked?Well, sixteen meters,
That is impossible. The suction height of the pump is caused by the centrifugal force of the vacuum. The water is sucked into the vacuum
Q:Why does the centrifugal pump start and close first when the outlet valve is closed?
The contact is burned out, the bond and so on the accident, therefore closes the outlet valve, starts the electric machinery, at this time the electric machinery belongs to the no-load current movement, greatly reduces the big current impact
Q:How do vacuum pumps and pumps work together?
The role of the check valve:"[the water pump impeller is not closed" refers to the pump suction pump before the water without water inlet pipe and water outlet pipe gas should be connected] is a connector, a connector, still can make the level surface, in order to prevent the water flow along the pipe, until it reaches the level of the flush, then increased check valve.
Q:Troubleshooting of diaphragm pump
The ratio of flow to water weight at a specific weight of --68F. 68F water has a specific gravity of 1Static suction head - the vertical distance from the liquid level to the central line of the pump. The pump shall be above the level of the liquid.Vapor pressure the pressure of all the steam on the free surface of the liquid. In any pump operating system, the operating pressure shall not be lower than the vapor pressure, otherwise the steam will be partially or completely cut off into the pump fluid. Viscosity - because of the presence of friction in the fluid, the property of viscosity gives the fluid resistance to flow.Water hammer action -Water hammer is a sudden power failure, or in the valve closed too fast, due to pressure, flow of inertia, produce water shock waves, like hammer hammer, so called water hammer. The force produced by the flow of water shock waves can sometimes be very large, thereby damaging the valves and pumps. Water hammer effect refers to the inside of the water pipe, the pipe wall is smooth, flow freely. When the opening of the valve suddenly closes, the flow of water to the valve and the tube wall, mainly the valve, will produce a pressure. As the pipe wall is smooth, the subsequent water flow in the role of inertia, the fastest reach the maximum and damage, which is the water conservancy "water hammer effect", that is, "positive water hammer.". This factor should be taken into consideration in the construction of water conservancy pipelines. On the contrary, the valve closed in a sudden opening, it will produce water hammer, called negative water hammer, but also a certain destructive power, but not the former big.. Causes and treatment methods of common failures of diaphragm pumps:
Q:What is the distance between the pump and the wall?
What do you mean by that? If your pump is parallel to the wall! Then, the wall of the pump near the wall is usually 500mm. This is an empirical data, considering the import pipe length, pump maintenance and motor heat dissipation and other aspects of the situation to determine. Dozens of pumps installed in our company are placed in this size! Hope to be of help to you.
Q:Water pump can not be pumped out, how to maintain water?
Packing overheating:Due to packing too tight, the cooling water can not enter the filler, or the shaft surface damage. Measures for proper relaxation of packing and cleaning of sealing pipe are adopted. Filler wear must be replaced with new ones. Before installation, soak in the oil and rotate it in turn. The incision should be staggered so that water leakage can be reduced. Fill the last lap after installed loading pressed to cover operation for further adjustment of the tightness.
Q:What is the principle of a turbopump?
Turbine [turbine] is a machine that converts the energy contained in a fluid medium into mechanical work, also called a turbine. Turbine is the transliteration of English turbine, derived from the Latin word "turbo", meaning "rotating object".
Q:What are the starting and stopping procedures for centrifugal pumps?
Before using the centrifugal pump, the operation instructions of the centrifugal pump shall be read carefully and the specific operation procedures shall be understood so as to make proper use of the centrifugal pump products. The first step is the operation of centrifugal pump inlet valve of centrifugal pump centrifugal pump for all open cavity filled with liquid, close the outlet valve, start the motor, the motor speed is normal, can gradually open the outlet valve, to adjust to the desired condition. Pay attention to self suction centrifugal pump starts to open the exhaust valve, outlet valve should be opened quickly in the normal operation of the motor, to prevent air inlet pipe off caused by cavitation phenomenon produces centrifugal pump, centrifugal pump vibration phenomenon leads to noise of the smoke is not on the water.
Q:How to select metering pump head?
The main index affecting the selection of the pump head is the composition of the medium to be transported and added, as well as the pressure and the temperature of the external environment
