Structural Characteristics of Single Stage Double Suction Split Casing Pump

1, Compact structure
Nice appearance, good stability and easy installation.
2, Operate steadily
The double suction impeller which is optimum and designed by computer, and has a large inlet flowing area. The clapboard is set at packing box of inlet flow passage, it makes no vortex at inlet of pump. It adopts resin sand moulding and high quality cast technology to make the inner surface of pump casing and the surface of impeller smoother than before. Through above measures, we make pump operate with no vortex, operate smoother and have remarkable erosion-resistant ability and high efficiency.
3, Bearing
Excellent bearing is used to assure the steady operation, low noise, long service life. Grease lubrication and closed structure is used. If thin oil lubrication structure is needed, a constant level oil cup shall be equipped.
4, Shaft seal
Mechanical seal or packing seal shall be used. These two kinds of seal are all installed in the removable packing box, which is convenient to assembly and maintenance. The packing gland of pump is removable and open, which assures enough room for maintenance and repair.
5, Impeller
The latest technology is adopted as well as the best hydraulic model, which makes the double suction impeller can balance the axial force automatically.
6, Shaft
Shaft is completely sealed without contacting the medium or corrosion. The length of the shaft is shortened compared with that of S, SH type pumps, and it is hard with no vibration. A replaceable shaft sleeve is installed on the shaft. There is no thread on the shaft, and o-ring structure is adopted to assure shaft and bearing do not contact the medium to improve the service life. It is easy to assemble without adjustment. Pump rotor part shall be installed with elastic prestressing force, which makes the installation and disassembly much easier and more convenient.
7, Casing
For the pump of high head, double split casing passage is adopted, which counteracts most of the radial force and prolongs the life of bearing on two sides.
According to the different mediums and using requirements, main parts of the pump can adopt various materials

 

FAQ

Q: Can your pumps mount Eff.1 motors

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

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:Cost of water pump replacement in 2001 PT Cruiser?
They vary in price but at the right auto parts counter you might find a brand new or rebuilt water pump for about 75 bucks or so but no more then about 160 bucks.The labour on those takes a few hrs anywhere from 4 to 6 hrs or less all depends on the tools and the mechanic. Check around for the part and the labour costs and sometimes it's better when it's a job like this that will cost at least a good 275-400 in labour costs plus taxes to have the shop supply or sell you the part bec then the shop truly should warranty the part via their part supplier and warranty their own labour work too.Also some shops here in Canada charge from 69 to 89 an hr or higher but there are also some shops that will offer a flat rate for work done by them too.So if you have a shop wanting 80 an hr and to charge for 6 hrs or more they could end up charging you well over 600 bucks just for the labour alone. Hope that helps and best of luck.By the way if you do end up deciding to fix that vehicle there could be some shops in the local smaller towns that might offer you the lower rates due to them being family operated or owned etc and I'd try to find a shop that has done lots of that same vehicle make work.
Q:Car repair price question: water Pump?
It depends on the car. Also, the shop was probably quoting you a factory new part. Just get a couple of quotes from different shops. On a Lexus LS430, water pump is a major job, over $1000 at a dealer. On a 60's GM car, it's about 90 minutes of work if you take your time, so there might be the difference.
Q:what would cause a domestic water pump to seize?
Depends on the type of pump, but for your garden variety type pump, there is a impeller of some sort that is turned by the motor to pump the water. The actual shaft of the motor is not in contact with the water (except where the impeller is attached to the shaft). A common type of failure mode here is when the seals on the shaft (which keep the water contained to the impeller area) have failed and water has gotten past the shaft seal and degraded the bearings holding the shaft = seizing up.
Q:Dry Bearing in my water pump?
A 'dried' bearing is sure to fail. Bearings without lubricant don't last long. I'm having trouble with my new waterpump. Bought it from AutoZone and it's already squeeling after 6 months. My water pump has a tensioner pulley built on to it. That's where my noise is coming from.
Q:Where can you buy a water pump?
It's time for a new pump, this is not an appliance that you want to worry about or cut corners with. I would recommend a plumbing supply house that has a little better quality pump. Zoeller makes a very reliable submersible, you won't have to worry for another 15 years.
Q:Determine the isentropic efficency of a water pump?
Well!!!!!!!! Isentroipc Efficiency of a pump = Isentropic Work / Actual Work At state 1, Enthalpy of Saturated Liquid h1 = 413.357 kJ/kg Entopy s1 = 1.29154 kJ/kg-K At state 2, Enthalpy of Liquid at state 2 = 448.042 kJ/kg Now, to find the ideal Enthaply , Enthalpy at 5 M Pa at entropy of 1.29154 kJ/kg-K h2s = 418.462 kJ/kg Thus, Isentropic Work Done I = h2s - h1 = 418.462 - 413.357 = 5.105 kJ/kg Actual Work Done A = h2- h1 = 448.042 - 413.357 = 34.685 kJ/kg Hence, Isentropic Efficiency = I/A = 5.105/34.685 = 14.72%
Q:furnace water pump spraying water?
Blue pump, usually found on the floor near the furnace (sometimes mounted where plenum meets the furnace frame) is a condensate pump. One of the products of combustion is water. This water is drained from the ventor motor (a motor which runs and sets a artificial draft inside the combustion chamber) to a drain nearby or a electric pump which then pumps the water over a longer distance to a remote drain. If the pump's discharge outlet gets plugged from dirt the result is usually the mess you see. Remove the cover plate of the pump housing, clean it out and run a wire with a small rag attached as a snake through the tube to drain. There is usually some type of float switch inside the pump housing so make sure it is free to move. Check for operation by pouring some tap water in it and move the float switch to on (up) One final note and this is very important. If the pump or tube to drain is filled up with a crud that resembles paste, call your local trusted HVAC tech for furnace service. This condition can be an early sign of heat exchanger failure and is a major safety concern for your family
Q:question about water pump?
If the sand is suspended in the water then yes there are pumps that will pump it. Other wise no.
Q:Water pump maximum flow and standard flow?
The parameter standard of the pump factory is determined by its efficiency, that is, the efficiency of the pump is highest at that point. All parameters have two curves, that is, a flow curve and an efficiency curve. You can according to your standard flow, see how much the efficiency of the point, the maximum flow efficiency is how much will know.
Q:Why can't vertical water pump use spring shock absorber?
Building water supply and drainage and heating engineering construction quality acceptance specification (GB50242-2002) on the 4.4 water supply equipment installation 4.4.6 regulations. Because the spring damper is not conducive to the stability of the vertical pump running, therefore, the vertical water pump damping device should not use spring shock absorber.
