6. FAQ for CNBM Pumps

1>  Can I get trained on CNBM products?

Yes, we provide training courses in our factory (products, general and specific pump technology, hydraulics, and practical applications). Please consult your sales manager or get in touch with our headquarters for more information.

2> Are your pumps cheaper than those of your competitors?

CNBM aims to give its customers the highest standards of quality and service and delivery times, all at a reasonable price.

3>  How long is your warranty?

Unless otherwise expressly authorized in writing, by specifying a longer period or different conditions, CNBM states that, for a period of twelve (12) months from delivery date, all Products supplied are free from defects in materials and workmanship, and conform to the applicable specifications. Either the delivery documentation or the invoice must be provided to prove delivery date. In absence of such documents, the production date appearing on the product label may suffice.

4> Can your pumps mount Eff.1 motors

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

5> Are your pumps protected against dry running?

No, unprotected centrifugal pumps are not generally designed for dry running. It is important to give us or your dealer as much information as possible about the system in which the pump is used. Inlet pressure, the type of liquid to be pumped, together with relative density, viscosity and temperature, for example, are required in order to allow CNBM to recommend the right pump with the right gaskets for a long operating lifetime.

6> How can I get trained on CNBM products?

Yes, we provide training courses in our factory (products, general and specific pump technology, hydraulics, and practical applications). Please consult your sales manager or get in touch with our headquarters for more information.

Q:What is the water pump population pre rotation, what harm?
Is the entrance of water flow in the formation of complex turbulent flow, flow direction, shock, vibration, easy to damage the front entrance device, such as vane impeller, shaft sleeve, sealing element.
Q:My fish tank pump is deep enough, it doesn't bubble up. Without oxygen supply, but it can filter. Does it damage the pump itself?
First tell you the pump not bad, just can't carry oxygen rinse, now he is equivalent to a 2 in a filter of the submersible pump, without any damage to the pump itself, three in one pump is actually in the 2 water outlet and air pipe, pressure by fluid flow is the principle of position the smaller the air drag, now a large pressure, oxygen loss of function, but the pump itself, his work without any change, so do not burn, rest assured it
Q:The role of impeller in water pump
Pump impeller through the motor to drive rotation, so that the medium (water) by centrifugal force or lifting force, so that the medium has mechanical energy (kinetic energy)
Q:Pump house should be equipped with those equipment and valves
The room should be full of equipment!
Q:Submersible pump reverse impact on the pump
Small amount of water, large current, long running time, easy overheating, or even burning pump.
Q:Fire pump control cabinet installation distance, ground height should be how much?
We know that the fire pump control cabinet has the distinction of floor and wall mounted, wall mounted control cabinet installation height generally is determined by the employer departments, without any special labeling, proposed control cabinet frame under the 120cm from the ground, this is the installation height compared to the commonly used, can be used for your reference.
Q:What does the lift of a pump mean?
Simply from the local to the pumping pumping height calculation of rice
Q:Fire hydrant and fire pump adapter difference
Fire hydrant is out of water, the water pump is water supply to the pipe network
Q:Two pumps automatically switch start control circuit,
The puddle is full, the float switch is closed, and the relay J1 works to drive the first motor. The J1's work makes the intermediate relay 'J' work and locks itself, preparing for the work of the second machines. The water level is lowered to the required minimum position, the ball is broken, the motor is stopped and the motor is stopped. When the water level rose to the highest position again, the floating ball closed again, the relay J2 and self-locking relay J2 to drive second motors, instant intermediate relay are opened, when the water level again be reduced to the lowest position, float off, the motor stops working, stop by working in front of the intermediate relay. The whole circuit back to the original state. So that the two motors work alternately.It should be noted that the circuit diagram for simple to understand, only painted the control circuit, there is no main circuit, there is no missing phase, leakage, over-current and other protection, the actual installation needs to be installed. There is the role of time relay is to ensure that the relay J2 normal work, the intermediate relay is disconnected, so that the motor 2 does not occur wrong action, time relay can be set to a few seconds, or even less than a second. Intermediate relay can also be controlled by time relay, and its time is also set very small, so as to avoid J2 short time possible power supply.
Q:What's a small soft pipe for a submersible pump in a fish bowl? How do you use it?
Filter pump for oxygen spray. If the filter pump water flow, you can throw oxygen flowers, you can not use. With that pipe, it's loud and kind of
