Product overview

Fourth generation KQL, KQW series single-stage single-suction centrifugal pump, is my company USES the best hydraulic model, and according to the working condition of all types of users under different conditions of use carefully designed. This series of products, compact structure, reasonable, stable and reliable operation; Configuration of special machine sealing structure, improve the operating environment, extend the service life; High efficiency and energy saving, low operating cost, saving management costs; Cover an area of an area small, save construction investment, favored by the market.

Application field

The central heating system of circulating water; Refrigeration, cooling circulating water of air conditioning system

Water treatment, sanitary water; Indoor living water supply, domestic hot water system

Water supply, water irrigation system; Flushing system with water

Product features


1, the pump and motor directly connected, pump shaft completely concentric, small vibration noise is low; Special structural configuration of bearing, impeller cantilever short, operation is stable and reliable

2, the use of forced circulation should not be restricted to the special structure of configuration of mechanical seal, improve its running environment, prolong service life

3, advanced pump chamber and the impeller design, make the pump has the superiority of hydraulic characteristics, ensure the pump efficiency and energy saving, low running cost, cut down the cost of operation management by 50% to 70%

4, unique installation structure greatly narrowed the pump cover an area of an area small, save construction investment from 40% to 60%

5, stainless steel shaft, never rust, guarantee the mating part tear open outfit is simple, reliable mechanical seal bellows seal, maintenance-free, easy to maintain。

- Inquire about price/MOQ

Q:Does vacuum pump oil belong to dangerous goods?
Absolutely not. We often send oil by express or by freight. There are no problems at all. Don't be afraid, don't burn, explode
Q:Do you have a suction pump higher than 9 meters?
This screw self-priming pump suction process can be more than ten meters or more, my family is using this
Q:Is the diaphragm pump and the drain pump one?
Therefore, the need to play a liquid discharge pump, if the medium is corrosive liquid, high viscosity, volatile, flammable, highly toxic liquid, you can choose diaphragm pump. Conversely, the general liquid, there is no special requirements, you can use the general centrifugal pump to reduce costs.
Q:What is the main difference between SK water ring vacuum pump and 2BV water ring vacuum pump?
The unified corrosion resistant design of bronze impeller improves the corrosion resistance of the pump, and the stainless steel material is more suitable for more severe applications;
Q:What does centrifugal pump mean horizontally?
Centrifugal pump: centrifugal pump is a centrifugal force on the impeller rotates to transport liquid pump. Centrifugal pumps use the impeller to rotate and cause centrifugal motion of the water to work. The pump before starting to pump shell and the water pipe filled with water, and then start the motor, the pump shaft to drive the impeller and water do high-speed rotation, centrifugal water movement, was thrown to the outer edge of the impeller, the pressure water pipeline flow through the volute pump into the pump shell.
Q:What is the name of the day pump and ground pump? Specific introduction
PumpGround pumps are used very frequently in many large basements, because they have no boom, so they need to be taken over manually. In addition to the site, for those days to pump the high-rise buildings, such as 200 meters or 200 meters altitude, can also take over to transport concrete by pump, but the premise is to have enough power to pump concrete will hit above the height and the length of nozzle can reach the height of the floor.Thus, the day pump and ground pump have their respective advantages. The pump is easy to use, but the ground pump can make up for the height that the pump can not reach. At the same time, the price is relatively cheap, so users can choose the corresponding concrete pump when they are in use.
Q:What's the meaning of the pump head in the water pump, please advise, thank you
In general, the pump removes the motor, and all the fittings are part of the pump head.A pump is a machine that transports liquids or pumps liquids.
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:What is a feed pump?
Because under normal circumstances, the water pump suction port flow rate is low, can not meet the requirements of high pressure water injection pump. Therefore, the purpose of adding a feeding pump at the front of the water injection pump is to increase the flow rate of the inlet of the high-pressure water injection pump so as to meet its water supply requirements!
Q:Fire hydrant pump button, under what circumstances do not need to install?
General high voltage system, when normal, use small pump steady pressure.Fire hydrant button lifting pump is one of the multiple pumping methods, and it is an important link of reliable operation of the system.
