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

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 does electromechanical vector pump mean?
It is a close set of mechanical and microelectronic technology. It adopts dual control center mode to control, and has a new water pump with logic control center and IPC control center.
Q:How many concrete pump tube diameter
The pump is generally divided into 125 and 150 two, the inner diameter is 125mm and 150mm. And the two kinds of each have high and low pressure points. Low pressure type type 125 pump for the pipeline diameter is phi 133,
Q:What should I pay attention to when buying a pump?
There are hundreds of water pump manufacturers in China, some of the family owned private enterprises are assembled in some areas, and the quality of the products is very good and bad, which makes it difficult to choose and buy. The main points are as follows:First, according to the required flow, lift, shaft power, efficiency, the necessary cavitation margin (or suction) and the use of conditions, the initial determination of the pump type, name, select the rated value and the required parameters of the same pump.
Q:What are the conditions required for hydraulic pumps to complete oil absorption and compression?
There must be one or more sealing volumes, and the volume of work is variable;
Q:The function of centrifugal pump
6. Stuffing box mainly consists of packing, water seal ring, stuffing box, packing gland and water seal pipe. The function of the stuffing box is mainly to close the gap between the pump shell and the pump shaft. The water in the pump is not allowed to flow outside and the outside air is not allowed to enter the pump. Always keep the vacuum in the pump! When the pump shaft and packing friction heat, it is necessary to rely on water seal to control water into the water ring, so that the filler cooling! Keep the pump running properly. Therefore, in the water pump running inspection process, the stuffing box inspection is to pay special attention to! In the operation of about 600 hours, it is necessary to replace the packing.
Q:What is the Rhodes pump?
The ultimate vacuum of roots pump depends on the pump structure and manufacturing accuracy, and also depends on the limit vacuum of the front pump. In order to increase the limit vacuum of the pump, the roots pump can be used in series. The working principle of roots pump is similar to roots blower. As the rotor continues to rotate, the gas is pumped from the intake air to the space between the rotor and the pump housing V0, and then discharged through the exhaust port. Since the V0 space is fully enclosed after inhalation, the gas in the pump cavity does not compress and expand. But when the top of the rotor turns off the edge of the exhaust and the V0 space communicates with the exhaust side, the gas pressure at the exhaust side is higher, and a part of the gas flows back into the space V0, causing a sudden increase in the gas pressure. As the rotor continues to rotate, the gas is expelled from the pump. Roots pump in the pump cavity, there are two "8" shape of the rotor perpendicular to each other on a pair of parallel axis, by a transmission ratio of 1 of a pair of gear belt movements synchronous reverse movement of each other. In the rotor, the rotor and the pump housing between the wall to maintain a certain gap, you can achieve high speed operation.
Q:How to calculate the motor power of metering pump?
Two Hydraulic power, metering pump rated flow (L/H) X, maximum pressure (Barg) / 36000 = kw
Q:Working principle and structure of external gear pump
The principle of the gear pump, gear pump structure consists of two gear mesh together with each other, and composed of pumps known as gear pumps. It relies on the gear teeth meshing space change in volume to transport the liquid, it belongs to the rotary pump, also can be considered as a volume pump. There are many kinds of gear pumps. According to the meshing mode, it can be divided into external gear pump and internal gear pump. According to the tooth shape of gear, it can be divided into positive gear pump, helical gear pump and herringbone gear pump.
Q:Hydraulic pump displacement refers to the pump shaft what?
You can see the sign of your hydraulic pump. There will be a displacement **ml/r in the sign of the hydraulic pump (r stands for every turn, ML is milliliter)
Q:What flowmeter is installed after the pneumatic diaphragm pump?
According to your entire pipeline system to flow meter ah!How about the pressure, the material, the digital float or what?You must be sure of the size of the flow
