5. FAQ

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:Why does my water pump switch on and off about every 5 seconds?
It sounds like the bladder in your pressure tank has ruptured.
Q:What are submersible water pumps?
they are sealed so that all electricl parts are water proofed
Q:Pump head is too high what's the impact?
Measure the height of 50m, using 100m lift pump, the disadvantage is a waste of energy, such as the selection of 100m lift pump, flow of 10 cubic meters, motor power 5KW, with less than 5 0m lift pump, flow of 10 cubic meters, motor power 5KW, so that the lift ratio measurement height is greater than 10-20%, on the same pump motor power next, the pump head is larger, less water.If the height of 50m is measured, the pump with 100m lift head is used, but what is the influence of the flow rate on the pump or pipe?.
Q:What is a 1 inch water pump?
The outlet is 1 inches (25MM) of the water pump
Q:How do i change the water pump on a 2000 s-10 4.3 litter 4wheel drive with air conditioning?
Spray some water on the belt while it's schreeching to rule the belt out. They often make noise, even when tight.
Q:I have a 1990 dodge caravan 3 L and my water pump is leaking but i keep water in it and it hasnt over heated?
You can. But I caution it will get worst over time. The unfortunate realty is only make short trips cause it will just start pouring out sooner or later. And then its over. Keep a eye on it. A water pump/timing belt is cheaper than a new van or motor. I think both are required when doing a pump on that one, so I'm guessing that's why we've not fixed it?
Q:water pump in car?
Note that the main purpose of a water pump in your car is to keep the engine cool. The heat that you get through the heater comes off the smaller hoses on the water pump. If your car isn't overheating chances are the pump is ok. Check your engine temp after the car has ran for awhile. The temp guage should go up when the car is warming up, then the guage will drop when the thermostat opens. It won't drop alot but you should be able to see it. Another thing you can try is to follow the heater hoses to where they go into the firewall and touch them after the car has ran for awhile. If your heater is on full they should both feel about the same temp. There is a control valve on the heater hoses that regulate the flow of water to the heater core and this valve may not be working properly.
Q:can i drive my car to a service center 5 miles with a blown water pump?
its possible. i dont reccomend it, but if you do, get a couple or few gallons of just water, depending on how big your radiator is, and keep an eye on your temp gauge, if it starts going up, shut off your car, wait 5 to 10 minutes, carefully open the cap on your radiator, and put water in it untill it fills back up. i had a busted water pump i drove 20 miles on everyday for about 3 days untill i had time to fix it, it wasnt a bad leak though, and that still sucked, i would honestly just pay the small amount for a tow truck for the 5 miles.
Q:Power flow conversion of water pump
Pump shaft power (kw) = water supply (L / s) x lift (m) /102 * efficiency = flow * lift * density * acceleration of gravity.Explanation:102 is the unit collation constant.Pump effective power / pump shaft power = pump efficiency (general 50%--90%, large pump higher)Unit time pump liquid volume flow is, flow by Q, a unit of measure: m3 / h (m3/h), L / S (l/s), L/s=3.6 m3/h=0.06 m3/min=60L/minG=Q G refers to weight - liquid proportionThe energy obtained by pumping a liquid of a unit weight is called a lift. The pump head, including suction stroke, is approximately the difference between the pump outlet and inlet pressure. The lift is expressed in H, and the unit is m.The efficiency of a pump is the ratio of the effective power to the axial power of the pump. ETA =Pe/P pump power usually refers to the input power, the motive power to the pump shaft, it is also called the shaft power, denoted by P. Effective power is the product of pump head and mass flow and gravity acceleration
