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.

- Inquire about price/MOQ

Q:What are the conditions for the series and parallel connection of the pumps?
Water pumps in series require equal flow, and the latter should be able to withstand the pressure of two pumps and.The parallel pump requires the pump with equal lift head, and the outlet pipe in parallel shall be chosen according to the flow rate of two pumps.
Q:Should my mechanic have changed thermostat with water pump?
I agree with Scott.Truth is though the water pump is a completely different issue than a thermostat.The only relation they have is both are part of the cooling system.If it had been me doing the water pump i wouldn't have changed the thermostat either
Q:In the design specifications, for example, the water pump requirement is two. What does that mean? Can 3 pumps be opened at once?
May not。Design is in accordance with the "two prepared" design, opened two units, has been able to meet the water supply requirements. And the electrical control parts are in accordance with the opening of two units, has been unable to meet the opening of 3 power distribution needs. The standby pump is only replaced when the running pump is out of order or needs downtime to maintain the water supply.
Q:Location of 2000 Impala water pump?
You see the big hose that enters your rad on the top well follow that hose and see were it comes from the engine..and that's the water pump..pretty simple thing to find my friend..good luck
Q:What all do I need to replace the timing belt and water pump?
HOW MANY MILES! This is a TOUGH CALL because a CONTINENTAL TIMING KIT for a HONDA is about $200 with NEW WATER PUMP PULLEYS and and BELT! A HIGH MILEAGE HONDA from taht year may bend a few VALVES if the belt breaks BEFROE you repalce it! Thsi wil requrie a NEW HEAD GASKET and a few new VALVES! AT this time NEW VALVE SEALS can be installed! An independent shop can do ALL THIS for about $1400-1500! he BELT KI is like waht I said here! OTHERWISE use ONLY GENUINE HONDA PARTS int here! teh CONINENAL kits are GREAT and made to HONDA PRECISION as well! PULLEYS and ENSIONERS are involved in thsi process, and only GENUINE HONDA COOLAN should be used ONLY! NO PRESTONE! Stay away from VALVOLINE OIL as well, it is made by WAX REDUCTION METHOD!
Q:how to identify water pump on Frankenstein car?
It's a Gen 1 small block V8. There are only two types of small block water pumps, long shaft and short shaft. Short shaft pumps were used on pre 1968 motors. The long pump measures 7 1/4 from the mounting surface to the outside of the clutch mounting flange, the short pump measures 5 5/8. The mounts should be for a small block in the same body type you are using it in. Back in the 50's there was a different mounting system that bolted to the front of the block, but everything since then is compatible. By the way, if the motor is in a 1966 body with the standard radiator, use the short water pump, iron or aluminum makes no difference except in cost.
Q:Water pump for distillation unit?
The only thing you might need a pump for is if you are distilling/refluxing something and it is not all condensing before it reaches the end/top of the tube, resulting in vapor escaping. In that case you would use a bucket of ice water with a submersible pump.
Q:Is water pump replacement necessary when it is working fine?
The labor involved in replacing a timing belt will normally cover the installation of a water pump as well. The reason the dealer is recommending the water pump replacement at this time is that the labor involved in changing the timing belt makes it much more cost effective for you to do it at this time. Even though your water pump is working great right now, if you need to replace it in the future, the labor cost will be enormous and close to the cost of replacing your timing belt alone.
Q:how much does it cost to change a timing belt and water pump on my a car?
If it's Japanese, every 90,000 miles. If American, every 60,000 miles. Just recently changed belt and water pump on my Honda for $400 at an independent. Dealer is more expensive.
Q:Water pump maintenance what should be maintained?
1 by sound to determine whether the bearing is good. If the sound is abnormal, replace the bearing.2, check whether the impeller is worn, if worn, will affect the flow, lift, efficiency, need to be replaced.3, check whether the mechanical seal can continue to use, can not be used, need to be replaced4, check the oil tank is missing oil, such as lack of oil to the appropriate location.
