1. Production Introduction for ZB Series Self-Priming Centrifugal Water Pumps: 
WZB self-priming pump is divided into single phase and three-phase asynchronous types with built-in protection device. The pump is divided into centrifugal impeller and worm casing structures with self-priming function. Single-face mechanic sealing is mounted between pump and motor."0" shaped oil-proof rubber seating ring is used at each stationary port as static sealing.

2. Application for ZB Series Self-Priming Centrifugal Water Pumps
This series pump is a new type of ideal economical pump, widely used in pumping water, increasing water pressure, garden irrigation, water supply for vegetable green houses, industrial mining enterprises and aquatic breeding fields etc.

3. Work Conditions for ZB Series Self-Priming Centrifugal Water Pumps
The pump can work properly and continuously under following operational conditions:
1.Medium is not corrosive.Sand contents should be max.0.10% by volume and granular size should be max.0.20mm.
2.Medium temperature shouldn’t be over 40°C and PH should be 6.5-8.5.
3.Power frequency should be 50Hz,single phase voltage 220V, three-phase voltage 380V,and voltage fluctuation should be 0.9-1.1 times than the rated.

4. FAQ for ZB Series Self-Priming Centrifugal Water Pumps

1. Are CNBM pumps available in DIY stores?

Yes, currently, we’re available for DIY stores all over the world.

2. Where do I have to send pumps for service?

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

3. Are your pumps acid-proofed?

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: Troubleshooting of diaphragm pump
The ratio of flow to water weight at a specific weight of --68F. 68F water has a specific gravity of 1Static suction head - the vertical distance from the liquid level to the central line of the pump. The pump shall be above the level of the liquid.Vapor pressure the pressure of all the steam on the free surface of the liquid. In any pump operating system, the operating pressure shall not be lower than the vapor pressure, otherwise the steam will be partially or completely cut off into the pump fluid. Viscosity - because of the presence of friction in the fluid, the property of viscosity gives the fluid resistance to flow.Water hammer action -Water hammer is a sudden power failure, or in the valve closed too fast, due to pressure, flow of inertia, produce water shock waves, like hammer hammer, so called water hammer. The force produced by the flow of water shock waves can sometimes be very large, thereby damaging the valves and pumps. Water hammer effect refers to the inside of the water pipe, the pipe wall is smooth, flow freely. When the opening of the valve suddenly closes, the flow of water to the valve and the tube wall, mainly the valve, will produce a pressure. As the pipe wall is smooth, the subsequent water flow in the role of inertia, the fastest reach the maximum and damage, which is the water conservancy "water hammer effect", that is, "positive water hammer.". This factor should be taken into consideration in the construction of water conservancy pipelines. On the contrary, the valve closed in a sudden opening, it will produce water hammer, called negative water hammer, but also a certain destructive power, but not the former big.. Causes and treatment methods of common failures of diaphragm pumps:
Q: There are 6 pumps, two indoor fire hydrant pumps, two spray pumps, two outdoor pumps, three units, one master and one spare control cabinet. From the control room to the control cabinet, is there only 3 lines or 9 lines?... How do I get it? Where does the hydrant line come from?
Indoor fire hydrant pump in addition to remote direct Kai, there are modules to start function, that is, on the cabinet to add control module, bus linkage pump, but also fire hydrant button, direct pumping function, a total of three functions.Outdoor fire hydrant pump in addition to remote direct Kai, but also an electric contact pressure meter detection system, water pressure from the pump and high pressure pump stop function.
Q: What is double hydraulic pump?
The 2 pumps are all coaxial connected together, driven by a motor, the general gear pump, piston pump
Q: Water pump can not be pumped out, how to maintain water?
Packing overheating:Due to packing too tight, the cooling water can not enter the filler, or the shaft surface damage. Measures for proper relaxation of packing and cleaning of sealing pipe are adopted. Filler wear must be replaced with new ones. Before installation, soak in the oil and rotate it in turn. The incision should be staggered so that water leakage can be reduced. Fill the last lap after installed loading pressed to cover operation for further adjustment of the tightness.
Q: Does the reservoir water heater press the booster pump (high marks)?
In addition, the water storage electric water heater has a safety valve is O.7MPa, before buying a booster pump, you can check the water inlet valve spring weakness, see the effect of water, barely even, then use it, do not buy.
Q: Pump operator's responsibility 10Sharing the rules, responsibilities, etc..
1., consciously abide by the traffic control department management rules, to achieve civilized driving, safe driving.2. responsible for the daily maintenance, cleaning and cleaning of the pump truck, and ensure the equipment is in good condition.
Q: Pneumatic diaphragm pump compressed air pressure is 4 kg, the discharge pressure is how big?
Generally slightly lower than 0.4MPa, Zai 0.35Mpa or so, if the outlet is blocked, the outlet pressure will equal 0.4MPa
Q: What is a feed pump?
Feeding the role of the pump is to make the injection pump inlet pressure, increase the injection pump inlet pipe flow rate, in order to ensure high pressure water injection pump has sufficient supply.
Q: Hydraulic pump displacement refers to the pump shaft what?
You can see the sign of your hydraulic pump. There will be a displacement **ml/r in the sign of the hydraulic pump (r stands for every turn, ML is milliliter)
Q: Which nuclear submarines use the shaftless pump technology?
Shaftless pumping technology and Simulation of shark skin technology are all the next generation of submarine propulsion technology. At present, there is no submarine in the world.
