Product Description:

Range of use of Water Supply System with No Negative Pressure

1. In order to adapt to the social development with the improvement of the living standard and qualit.

2. Additive pipe pressure (negative pressure) water supply equipment emerge as the times require, the device makes full use of the municipal pipe network pressure superposition, pressurized water supply, .

3. Superposition of pressurized water supply, small occupation of land, energy saving and environmental protection.

4. Tank structure superposed pressure (without negative pressure) water supply equipment long time over the municipal pipe network water supply operation condition of water use in the user, because the regulating tank storage capacity is limited, can not guarantee the normal water use of users, as well as the municipal pipe network short water, be no water available to the problem, in order to make the equipment performance to be more perfect, the company in on the base of original technology developed a new generation of the network pressure superposed water supply equipment of BW (III) type pipe network pressure superposed (non negative) frequency conversion water supply equipment.

Q: Where do I have to send pumps for service?

A: You must send them to the CNBM PUMP Service Point or, after contacting Customer Care, to the CNBM PUMP service center in China.

Q: Are your pumps acid-proofed?

A: To choose the right pumps for chemical applications, we do need further details on hydraulic operations as well as on the type, concentration and temperature of the liquid.

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:how to check water pump?
Take off your radiator cap, start the motor. If the water pump is working you will see the water flowing in the radiator. Do you have a temperature guage on your dash or just a trouble light. If you drive it and it does not overheat then it is working.
Q:No Water in house/well/pump?
If you are sure you have power to the unit, go to the pressure tank. There should be a pressure control switch with wires going in and out. It may have a reset switch that you can try to reset. You usually have to hold the switch for several seconds for the water pressure to build up past 20 pounds before you release the switch. You can tell if this is working by hearing water flow thru your pipes and/or watching the pressure gauge on the unit.

Q:Can I replace saturn vue water pump and thermostat myself?
Your car has only one fuel pump in the gas-tank of it's a four cylinder motor. It has only one fuel pump if the motor is a V-6. In both cases, change the fuel filter first. Have the fuel pressure checked in the fuel rail pressure fitting beside the fuel injector nozzles. No need to change the fuel pump if the pressure is at least 35 psi. No way in heck should it cost $900. to have the water-pump and thermostat replaced on your car. Pretty sure a Chevrolet dealer, who know services Saturn would charge that much! *Check out more trusted private mechanics for prices. We'd offer a glimmer of what it would cost but you forgot to tell us if the engine was a V-6 or four cylinder. Forget any kind of chain mechanical shop.
Q:My water pump is leaking?
don,t drive it or it will overheat. it could be the by-pass hose leaking instead of the pump.
Q:What motor with Grundfos pumps
Grundfos pumps with the motor Grundfos own.
Q:Is water pump working?
You have essentially two correct answers, but looking at the year of your engine I would like to add some clarity. If memory serves, the 1972 engine doesn't have what we today think of as a tell-tale. Meaning that nice little stream of water that comes out of a tube on the starboard side of the engine. Using my poor memory I believe there is and exhaust port, usually one or two outlets together, centered in the rear of the engine, just below the fiberglass engine cover, maybe a little lower. And again, if memory serves, water doesn't flow in a stream from there, but kinda comes bubbling/spraying out. This will be the place to check for exhaust water, and whether or not the impeller is working. Also, like the idea of using the earmuffs, just in case there is thru-hub exhaust you can see it also. If the hub is in the water you can see it exhaust water.
Q:I have a water pump question?
Pressure testing requires a device that attaches to the top of your radiator which allows you to pump air into the system. This test will not always reveal a bad pump however. Find the weep hole (usually on the bottom of the water pump) and look for signs of leakage. If you see coolant you need a pump. Also grab the top of the fan and wiggle it if the belt pulley moves you need a pump.
Q:water pump failure? or what?
I would check the thermostat. But you don't check it like the first answer indicates. Pull the thermostat out. Look at it if it is open it is bad. If it is closed put it in a pot of boiling water. If it does not move it is bad. This may seam like allot to go through but if it is not the thermostat your only out the cost of a new gasket. And you know for sure. If there is nothing wrong with the thermostat , than you aren't getting circulation. A few causes would be: Cooling system clogged water pump bad internal leak or external leak. If you have a leak the system can't build pressure.It will take a long time to warm up and or it will make you think it is over heating but it will only be a leak. It will also run hot. NEVER OPEN A RADIATOR CAP WHEN THE ENGINE IS HOT. YOU WILL BE GOING TO THE HOSPITAL TO HAVE YOUR BURNS TREATED!!!
