FAQ

  ◆Are CNBM pumps available in DIY stores?

Yes, currently, we’re available for DIY stores all over the world.

  ◆Where do I have to send pumps for service?

You must send them to the CNBM PUMP Service Point or, after contacting Customer Care, to the CNBM PUMP service center in China.

  ◆Are your pumps acid-proofed?

To choose the right pumps for chemical applications, we do need further details on hydraulic operations as well as on the type, concentration and temperature of the liquid.

  ◆Can your pumps mount Eff.1 motors

Currently, only on request though this will shortly be a CNBM standard.

Q:Water pump belongs to power equipment or mechanical equipment?
Ownership of mechanical power equipment in assets
Q:Does the water pump pump the coolant into the engine or pump it out?
The automobile water pump pumps the coolant into the engineThe effect of the water pump is used for cooling the engine; it is the coolant pump in the water tank into the engine of the channel, when the engine temperature is about 93-98 of the body's arrival, the thermostat engine open, cooling fluid from the thermostat back into the tank....
Q:The diving pump in the aquarium stops and stops on the goldfish
Submersible pump is used as if you push the pump filtration should be open for 24 hours, so the water circulation process, continuously into the fresh air to increase the oxygen content of water bodies two, filter on the filter of the continuous cleaning system to maintain water make nitrification safe and clean, the water can be fully introduced the content of nitrification ammonia water, let the fish live healthy and strong resistance, good activity, three appropriate water flow on the long time to keep fish, turn off and the formation of water to fish is always in a state of tension and decreased immunity antifeedant or death. Four, frequently start the pump, easy to cause damage to the motor coil, reduce pump life, so according to the above, if you are using submersible pump as a filter to promote, I suggest you open 24 hours.
Q:Flow 70 cubic meters per hour; lift 35 meters, choose what standard water pump?
1, what liquid transport, whether corrosive, there are no metal particles, or other dirty things2. Installation form (submerged pump, pipeline pump)Clear these issues, you can choose the pump according to requirements
Q:Pump flow 6M3/H is an hour, how many tons of water?
1.5KW pump if the head 90 meters, then the flow of 2 tons, more than the most
Q:1.5 kW three-phase pump with 600 meters line, should match what big line?
Do you want to see the line loss how much pressure drop, if you want to ensure the working voltage of certain you pump, 600m pressure drop should be two-way, namely power press 1200m, press 380V, 1.5KW working current is calculated according to 3A R=, according to the resistivity * length / cross-sectional area of =0.0175*1200/S=21/S, and the loss of pressure drop =R*I=21*3/S=63/S, S take 3, loss of pressure drop is about 20V, the comprehensive economic cost, take 3 more appropriate, if you are willing to take 5, 6 are never mind, the thicker the loss is smaller.
Q:How many kinds of pumps are there? What are the advantages of soft start?
Soft start is prepared, hard start is not prepared, the machine suddenly can not stand! Ha-ha
Q:What is the difference between a sewage pump and a clean water pump? Why can't sewage be pumped with clean water?
The main difference between water pump and sewage pump is that:Impeller and runner design, as well as other parts of the configuration are very different.1., in order to prevent clogging of sewage pump, the main design of large flow channel, so naturally lead to relatively low efficiency, so the head is generally not high. Clear water pump flow smaller, smaller clearance, the head is relatively high.2. in order to prevent the wound, water pump impeller design is more simple but not ring pump, equipped with tips, cloth and other debris can be crushed after the pump, and the impeller water pump is relatively complex, but the efficiency will be significantly higher than the former.Why can't the sewage water pump and impeller: because features of key design, resulting in water pump for sewage situation is likely to occur, blocking, winding, wear and corrosion occurs, resulting in damage to pump or scrapped, so water pump can not be used for sewage.Sewage pump is a pump and motor conjoined, and at the same time submerged into the work of pump products, and general horizontal pump or vertical sewage pump compared to the sewage pump compact structure, small footprint.The water pump is for the transport of water and physical and chemical properties similar to water and other liquids used, suitable for the industry and the city water supply and drainage, water pressure high-rise buildings, garden sprinkler, fire booster, long-distance transportation, HVAC refrigeration cycle, irrigation, bathroom, cold and hot water circulation pressurization and equipment.
Q:The wiper pump is broken. How much will it cost to fix it?
Hello, the wiper motor is broken, can only be replaced to solve the problem, different models of price difference is too large, general average car about 60-80. You can go to a few repair shop to ask, OK, you can also match the city or Taobao purchase.
Q:Water pump "rated lift: 6m" what do you mean?
Lift refers to the weight of fluid per unit weight after the pump, the pump is an important working parameter, also known as pressure head. Simply stated: rated lift 6M refers to the rated operating conditions of the pump, the increase of energy 6M water column height. Here's an example to help you understand:Example 2-1 the head of a centrifugal pump is now measured. The refrigerant is 20 DEG C water, the measured flow rate is 60m^3/h, vacuum pump inlet meter 0.02Mpa, outlet pressure gauge readings for the 0.47Mpa (g), the two known table between the vertical distance is 0.45M if the suction pipe of same diameter and pipe pressure pump, calculate the pump head.Solution:Check the water density at 20 centigrade 1.0*10e3kg/m3,H=0.45m (1Mpa approximately equal to 100 m water column)P exports =0.47Mpa (0.47*100 m water column, =47 m water column)P imports =-0.02Mpa (0.02*100 m water column, =2 m water column)P is the density of the liquidH=h+ (P -p / P g=0.45+ export import) (0.47*10e6- (-0.02*10e6)) / (10e3*9.887) =50.5m (water)
