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 is cavitation, centrifugal pump cavitation phenomenon how to solve?
First, what is cavitation?:When the centrifugal pump shell has air, it produces less centrifugal force because the density of the air is much smaller than the density of the liquid. Thus, suction pressure at the entrance to the top of the tank liquid level and pump is bad enough to the liquid storage tank into the pump, the centrifugal pump self suction capability, the centrifugal pump can not transport liquid, this phenomenon is called "cavitation".When a liquid drops at a certain temperature to the vapor pressure at that temperature, the liquid produces a bubble. The phenomenon of producing bubbles is called cavitation. When the cavitation bubbles, flow to the high pressure, the volume of reduced, so as to burst. This due to the pressure of rising bubbles disappear in the liquid in the phenomenon called cavitation bubble collapse.
Q:Is the vacuum pump air compressor?
No, both work in the opposite way. Air compressor, referred to as an air compressor, is a machine that produces compressed air (positive pressure). The vacuum pump is just the opposite.
Q:Which nuclear submarines use the shaftless pump technology?
Shaftless pumping technology and Simulation of shark skin technology are all the next generation of submarine propulsion technology. At present, there is no submarine in the world.
Q:Significance of water pump model ISO50-160
A pump is a machine that transports liquids or pumps liquids. It will be the prime mover of the mechanical energy or other external energy transfer to the liquid, the liquid energy increase, mainly used to transport liquids including water, oil, alkali liquid, emulsion, suspension emulsion and liquid metal, but also transport liquid, gas mixtures and liquids containing suspended solids. Pump performance parameters include flow, suction, lift, shaft power, water power, efficiency and so on;
Q:Filter backwash pump for what use, what is the principle of work ah?
Regeneration of the filter medium is required to regain the filtration capacity of the medium. The regeneration process is mainly accomplished by the backwashing pump (the backwash pump is not a special pump, referring to the pump for the completion of the process). The working principle is through the cleaning liquid from the downstream of the filter into the backwash pump (alkali, acid and water), reverse flushing filter medium, cleaning liquid discharged from the upstream, this process can be attached to the dielectric surface and internal impurities washed away.
Q:What are the internal losses in centrifugal pumps? How did they come about?
Volume loss: loss due to leakage;3. mechanical loss
Q:Suction stroke and lift of water pump
Lift pump lift pump can lift refers to the height, usually expressed in H, the unit is m. centrifugal pump lift to the impeller center line, divided by two parts. The vertical height from the pump impeller centerline to the water surface, the water pump to suck water up to the height, called water head, referred to as suction pump impeller; from the center line to the vertical height of the water tank, the water pump can put pressure on the height, called water pressure head, referred to as the pressure. The pump head = + suction head pressure water head should be pointed out that the nameplate marked head refers to the pump itself can produce lift, it is not with the pipe flow friction resistance caused by the loss of lift. In the selection of water pump, attention can not be ignored. Otherwise, will be pumping Sheung Shui.

Q:Double floor sewage pump circuit diagram of a small problem
Question 3 when the water level is low, when the 1KA is connected, the pump will run depending on where your SS selector switch is located. Its left and right position, running pump and standby pump definition is different, left position is 1#, running 2# standby, right position is 2# running, 1# standby. Only inIn case the high level switch 2KA is connected, the standby pump may work at the same time.
Q:The main factors affecting the performance of centrifugal pumps
The low specific speed pump, on the other hand, is suitable for smaller flow and higher lift. When the pump outlet pipe diameter at the same time, if the two pumps flow similar, smaller than the speed of small head, shaft power consumption is also large. Generally speaking, the centrifugal pump with smaller revolutions than the impeller has a narrow outlet width and a large outer diameter, and the channel formed by the blade is narrow and long. If the ratio of revolutions is large, the impeller outlet is wide and the outer diameter is small, then the flow passage is short and wide.I hope my answer will be helpful to you. I hope to adopt it!
