FAQ

Q: Are your pumps protected against dry running?

A: 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.

Q: How can I get trained on CNBM products?

A: 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: Are your pumps cheaper than those of your competitors?

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

Q: Do you have self-priming pumps?

A: Yes, our product portfolio also includes two ranges of self-priming pumps: self-priming electric pumps and self-priming side channel pumps.

Q: Is it really necessary to fit a bleed valve for the boxes?

A: It is always best to have a bleed valve as the gas produced by the fermenting sewage is potentially hazardous.

Q:auto repair water pump?
not too hard of a job 1.drain radiator/block of all anti-freeze 2.remove fan shroud 3.remove serpentine belt 4.remove fan unless its electric 5.pull the hoses. 6.remove bolts holding the w/p in place 7.clean all gasket area of old gaskets 8.dry fit new w/p to make shure new pump is right part 9.put rtv gasket on block where w/p will mount 10.put rtv on new w/p 11.put new gasket on w/p 12.mount water pump and snug up the bolts do not tighten 13.after allowing rtv to set for 24hrs tourqe bolts to spec. 14.reverse steps 5 to 1 15.check for leaks.
Q:Water pump cost??????????
Water pumps are cheap.. its the install time and or labor cost to do it that is pricey
Q:25 psi water pump?
Gonna need more info for this one, start with the usage requirements for the equipment you are supplying. That should give you something to talk about with the local sources. The size of the terrariums and the amount of water in each one, the height that you want to lift the water is another factor to be considered. Be sure to include the diameter of tubing to be used and any special features, fountains, misters, etc. Good Luck
Q:How to check a water pump on a 1998 Dodge Dakota V6?
Have you checked the valve that shuts off the coolant when the heater is not required? It, or the pipes/ hoses to it, may be blocked, or the valve inoperative. I'd bet the coolant is not being allowed to circulate through the core by something. Backflushing doesn't guarantee the core isn't gunked up, either.
Q:TDH what units are present in the pump parameters?
In the pump parameters, TDH is the head of President (Ying Chi).The formula is as follows:TDH (Ying Chi) = total head (Ying Chi) = (- water pressure readings + drainage pressure gauge (drainage dynamic head - water head + (drainage pressure gauge - water pressure elevation correction table elevation correction)
Q:01 Tacoma 3.4 V6, does anyone know the average life of the water pump?
Water pump life is a direct function of proper maintenance, therefore there is no real answer to your question. At 89k you could certainly elect to replace the WP as long as the T-Belt is also being done, but it is purely a preventive maintenance item. Might save you a lot of money later, or it might not. Impossible to say. It will give you more peace of mind though.
Q:after timing belt, water pump and all other belts what could cause constant squeal from engine?
You either have a belt that is too loose and slipping or a belt that is too tight and overloading a bearing, depending on the pitch of the squeal.
Q:What's so good about having a water pump on my stand alone ice maker?
How should the discharge hose be routed to the drain of the ice maker?
Q:Dodge Intrepid 2001, 2.7 L, why do water pumps break?
Mechanical water pumps break because they have a shaft that goes directly into a water pump housing. That shaft is driven on the outside by the accessory drive belt. on the inside of the water pump housing their is a impeller(a disk like that of a old mill house in the forest next to a stream). between inside the pump housing and outside there is a rubber seal to keep the coolant in. Because the rubber seal is exposed to heat drying occurs on the outside causing the rubber seal to on day get hardened. On the inside the hot coolant keep the seal pliable and soft. when air gets inside the coolant system with water it causes the seal to dry on the inside of shaft seal. When heat is on both sides of the seal exposed to air cracking occurs faster causing the seal to crack all the way through and spill water. Electric water pumps for cars are some of the most compact and powerful water pumps around for their size. Due to the extreme under hood temps and the constant turning on and off to save gas the electric water pump for cars have a short life. It used to be electric water pumps were only used in the drag race area; due to electric failure. Not until recently have companies started to deploy them among small cars and also as secondary pumps for turbo and supercharger applications with having a main water pump being mechanical.
Q:When using a frequency converter to adjust the pump, what is the relationship between the change of the speed and the efficiency of the pump?
The wind pumps such load is usually called square torque load, which is in a certain range of speed and torque is roughly proportional to the square of the speed of N, TL=kn^2, power and speed is proportional to the cube, the energy-saving effect is obvious.
