Product Description:
Application:
It is suitable for offshore platform fire-fighting, thermal dissipation, seawater desalinization, seawater lifting, coastal square fountain, mariculture and attemperation as ground source heat pump in coastal area. It also can lift underground drinking water and mineral water,etc.
Material:
QH series stainless steel submersible pump has several kinds of material.
Seawater and strongly corrosive medium: austenitic stainless steel 316, 316L, tin bronze,etc.
Moderately corrosive medium: austenitic stainless steel 304,etc.
Advantages:
CNC lathe precision machining ensures parallelism and perpendicularity of all the castings.
With rigorous testing, well installation and full load performance test, you can feel easy to use it.
Some of our products manufactured by introducing the Germany Ritz technology, improving the pump’s efficiency and making it more energy-saving & environment-friendly.
Motor parameter:
The motor is accord with GB/T2818-2002 pump industry standard, and it is lubricated by water. The motor must be filled with water. The standard length of the extended cable is 3m.
If you need special requirement, we can extend its length. The working temperature should be a little higher than that of common motor because of its poor magnetic conductivity.
Power:
The general power specification we supply you:380v/50Hz±5. We also can provide customised specifications at your requirements. The variation of voltage and frequency ratings and its influence on motor performance and temperature should meet the requirements of GB755(National Standard)
Notes:
We can provide you the suitable products if the actual working condition, the voltage or the frequency are not consistent with above specifications.
Working condition:
The motor should be submerged into water with the depth no more than 70m;
Solid content (mass ratio): ≤0.01%

- 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: What does the pump mortar do?
- In order to effectively reduce the flow resistance of concrete and pipe, to avoid obstruction caused by pipe sticking and to achieve normal pumping, and its role is generally only pumps.
- Q: Variable flow pumps are variable pumps
- Yes. The variable pump is designed to change the flow rate
- Q: What is the pump, how to classify, mainly used in where?
- 1. vane pumpThe impeller pump is driven by the impeller to rotate the liquid at high speed and transfer mechanical energy to the transported liquidAccording to the pump impeller and runner structure characteristics can be divided into different:1) centrifugal pump2) axial flow pump3) mixed flow pump4) vortex pumps3. jet pumpA high velocity jet produced by a working fluid is used to eject the fluid, and then the energy of the ejected fluid is increased by momentum exchange
- Q: Is the sewage pump the same as the mud pump?
- Two of the main performance parameters of mud displacement and pressure, displacement from a number of liters per minute, with the diameter and the drilling fluid requirements from the hole on the back end of the speed, the larger aperture, the greater the displacement. The upstream return speed of the washing fluid is required to remove the cuttings and rock powder from the drill in a timely manner from the bottom of the hole and reliably carry it to the surface. Through drilling and extraction, mud can be obtained at the bottom.Sewage pump is mainly used for industrial wastewater treatment, sewage treatment, environmental protection has played a big role. Among them, the sewage pump is also a sewage pump with cutting wheel, such sewage pump can be chopped dirt, and then extract the sewage clean.
- Q: Is the centrifugal pump large or small?
- NPSH is also called cavitation, cavitation is too big to be.3, pump the liquid when working in the impeller inlet will produce vapor due to a certain vacuum pressure, vaporization of the air bubbles in the liquid particle movement under the impact of erosion on the impeller, the metal surface, thus undermining the impeller and other metal, then vacuum pressure is called vaporization pressure, NPSH is excess vaporization pressure of surplus the energy position of the unit weight of the liquid in the pump suction port of. The unit with annotation, (NPSH) r with. The absorption process is necessary NPSH H: pump suction fluid allows the vacuum pump installation height is allowed, in meters.
- Q: How many square cables does the submersible pump for 7.5KW need?
- According to current I=13A, it is estimated that the cable is less than 10 square meters, so the cable cross section can be calculated at the ampacity of 5A per square meter. The square section of the cable is =13/5=2.6 square. According to the specifications series, optional 2.5 square aluminum cables. When the cable is longer, it is safer to choose 4 square aluminum cables.
- Q: No negative pressure water supply equipment, both the main pump and auxiliary pump, power is not the same, how to choose the control cabinet?
- Non negative pressure water supply equipment can be divided into non negative pressure tank and box type non negative pressure compensation device, steady flow tank type non negative pressure water supply equipment is the negative pressure tank, pressure tank can eliminate the negative effect of network equipment, is equipped with a vacuum suppressor and water protection box; non negative pressure water supply equipment has the advantages of simple device is a water tank with the boost voltage stabilizing device of complex box at the same time with no negative pressure tank.The tank type non negative pressure water supply equipment adopts vertical multistage centrifugal pump. This kind of pump is low noise and high efficiency. Such as CDL series and imported CR seriesOrdinary box type non negative pressure water supply equipment can use multi-stage centrifugal pump, also can use stainless steel submersible pump, submersible pump costs will be lower, but the maintenance costs will be high.
- 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: 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;
