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.

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: Know flow and lift how to calculate the pump power?
- P: the density of refrigerant, when the working fluid is water, P =1ETA - pump efficiency, can not find desirable value =0.8N=30x (200/3600) x9.81x1/0.8=20.44 = 20 (kW)(that is, 20kW motors)
- Q: Fire pump and shower pump flow head selection, high resolution.
- 3, larger than 25000, the minimum water consumption of indoor fire hydrant is 20L/s4, the minimum water consumption is the flow of a fire hydrant.
- Q: Why should the pump be closed when the centrifugal pump is started?
- Centrifugal pump has an important characteristic: when the pressure (head) is very low, the flow will be great, which can be seen from the characteristics of the pump curve. While the pump power is directly proportional to the flow rate, pump start, no pressure in the pipeline, caused by the pump flow, high power pump, and the pump motor, the rotating part from rest to high-speed operation, need a lot of acceleration, it will cause a great starting current
- Q: What is a solution pump?
- Principle and structure features of canned motor pumpThe ordinary centrifugal pump is driven by coupling the pump impeller shaft is connected with the motor shaft, the impeller and the motor rotates while working and shielding pump is a kind of non seal pumps, pump and motor is sealed in a medium filled by pumping the pressure vessel, the pressure vessel only static seal and, by a group of wires to provide a rotating magnetic field and drive the rotor. This structure eliminated the traditional centrifugal pump with a rotary shaft sealing device, it can do no leakage.The pump and motor pump together, motor rotor and pump impeller fixed on the same shaft, use of shielding the rotor and the stator of the motor rotor separated in the medium, its power is transferred to the rotor through the stator magnetic field.
- 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
- Q: What is the pumping property of concrete?
- Pumping capacity means that fresh concrete can be transported by concrete pump, and concrete construction can be carried out with high efficiency. 'pumping' is a qualitative statement
- Q: What are the constant pressure pumps?
- Constant pressure pump is also called the booster pump, the name is used for booster pump, its main purpose is water heater booster, with tall low pressure, sauna, bath and other pressure in the apartment, the lack of water pressure, solar automatic pressurization and so on.
- Q: Roots pump and dry pumpRecently involved in the work of the vacuum pump, don't understand this, is a ads602 vacuum pump, composed of roots pump and dry pump, is pre pumped to the 500mtorr equipment, the main pumping vacuum continues to 10mtorr, where the roots pump and dry pumps must be used? What role they play respectively. The so-called dry pump? Is refers to one kind of the pump, the pump is many dry pump? Also do not understand how the work of automatic switching system for pre pumping, the main pump, pump work alone did not connect system ah (of course there are even a butterfly) teach?
- 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: Why does the centrifugal pump start with a closed valve and the axial pump starts with an opening valve?
- Because the characteristic curves of the two are different.The power of centrifugal pump decreases with the decrease of flow rate. When the flow rate is zero, the power is minimum, so the centrifugal pump is started with a closed valve.
- Q: What are the failures and causes of the replacement of the fuel pump assembly?
- Common troubles of gasoline pump:Gasoline pump supply shortage of gasoline pump supply depends on the pump membrane stroke, stroke, pump oil should be more; however, the amount of gasoline pump oil pump will reduce the consumption of gasoline engine, and the fuel pump is inevitable, if the engine fuel consumption, but the actual amount of oil is less, this situation is the amount of oil in the petrol pump, there will be a float chamber of a carburetor oil level is reduced, the engine power shortage.
