Product Description:

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:Piston filling and peristaltic pump filling which precision is high?
First of all, we should know the working principle of each, and analyze the accuracy from the principle, this problem is very important. Piston filling, such as the injection of drugs that we have been ill, the accuracy of the piston pump depends on the accuracy of the motor and the area of the unit cross section
Q:The working principle of magnetic pump
Control of cooling fluid flowThe pump is running, you must use a small amount of liquid in the magnetic separation between the rotor and the casing annulus area and sliding friction bearings for flushing cooling. The cooling liquid flow pump design flow is usually 2%-3%, the annular area between the magnetic rotor and sleeve of eddy current generated because of high heat. When the cooling and lubrication the liquid is not enough or poor flushing holes to plug, will result in permanent magnet medium temperature is higher than the operating temperature of the inner magnetic rotor gradually loses magnetism, the magnetic actuator failure. When the medium is water or water-based liquid, can make the annulus area temperature maintained at 3-5 DEG C; when the medium or hydrocarbon oil that can make the annulus area temperature maintained at 5-8 degrees.
Q:What's the word "pump"? Is that what advocates mean?RT
What is a "fan"?In recent years, the term "fan" often appears on the newspaper Web page, whether it is a team, a singer, a sports car and a toilet, all of which have their own fans
Q:Filter backwash pump for what use, what is the principle of work ah?
When the filter is in normal operation, the impurity will be trapped in the upstream of the filter (filter medium). As the accumulation of impurities, the filter media will be blocked, and the direct performance is that the circulation will decrease. Usually, when the flow drops to a set point (the industry is usually judged by the pressure drop),
Q:The water tank of the fish tank does not air out and only has the water outlet
The picture above is very clear, but I didn't say anything about it. My problem is solved. The intake pipe and the exhaust pipe are connected by the inverted T type. The intake pipe is upward, but not fixed. It can be rotated. The intake pipe can be rotated to adjust the number of bubbles
Q:Must the water pump in the tank be all soaked in water?
Usually you have to soak it all in the water. If you don't want to put it in the water, you can buy an amphibious pump. At most, you can expose it
Q:Variable flow pumps are variable pumps
Yes. The variable pump is designed to change the flow rate
Q:What are the characteristics of the piston pump?
Piston pump is an important device of hydraulic system. It depends on the plunger in the cylinder in reciprocating movement, so that the volume of the sealing chamber volume changes to achieve oil absorption and oil pressure. Plunger pump with a rated pressure, compact structure, high efficiency and flow and easy adjustment, is widely used in high pressure and large flow and flow needs to adjust the occasion, such as hydraulic machine, engineering machinery and ships.
Q:Advantages and disadvantages of canned pumps
The ordinary centrifugal pump is driven by coupling the pump impeller shaft is connected with the motor shaft, the impeller and the motor rotates while working and shielding pump is a kind of non seal pumps, pump and motor is sealed in a medium filled by pumping the pressure vessel, the pressure vessel only static seal and, by a group of wires to provide a rotating magnetic field and rotor drive. The structure eliminates the rotary shaft sealing device of the traditional centrifugal pump, so the utility model can be completely free from leakage.
Q:Why does the centrifugal pump start and close first when the outlet valve is closed?
The contact is burned out, the bond and so on the accident, therefore closes the outlet valve, starts the electric machinery, at this time the electric machinery belongs to the no-load current movement, greatly reduces the big current impact
