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.

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: 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: What are the internal losses in centrifugal pumps? How did they come about?
- Due to the friction of the bearing, the friction in the stuffing box, and the losses caused by the rotation of the impeller (the loss of the roulette wheel);
- Q: What should I pay attention to when buying a pump?
- Four, packing inspection1. with the pump supply documents shall include: product certification, specification, packing list, agricultural pumps (such as submersible pumps, centrifugal pumps, mixed flow pumps, self-priming pump etc.) should be "Three Guarantees certificate", the implementation of the production permit (such as pump submersible pump, high pressure pump, high temperature pump 5 pump) we should have a production license.2. plugging of the orifice, to withstand wind and rain invasion, and should be strong, can withstand accidental damage.3. pumps and all supplied bulk parts supplied with the pump shall have the required identification number and shall be clear.4. pairs of oil lubricated bearings, bearings tank oil should be discharged, and fixed with "need oil filling" warning signs.
- Q: What is the principle of a turbopump?
- The working conditions of the turbine are different from those of the medium used, so the structure of the turbine is varied, but the basic working principle is similar. The most important component of a turbine is a rotating element (rotor or impeller) mounted on a turbine shaft with blades uniformly arranged along the circumference. The energy of the fluid is converted into kinetic energy in the flow through the nozzle, and when the fluid passes through the rotor, the fluid impacts the blade and drives the rotor to rotate, thus driving the turbine shaft to rotate. The turbine shaft drives the other machinery directly or through the transmission mechanism, and outputs mechanical work.
- Q: The difference between submersible pumps and centrifugal pumpsWhat's the difference between the two? What is applicable and what?
- 1. submersible pumpsA very wide range of water treatment tools. Unlike ordinary water pumps, it works underwater, while the pump works mostly on the ground.The working principle of submersible pumpBefore the pump is opened, the suction pipe and pump must be filled with liquid. Open the pump, the impeller rotating speed, which leaves the liquid together with the rotation under the action of centrifugal force, the left outside impeller injection, injection of the liquid in the pump shell gradually slow the spread of indoor speed, the pressure gradually increased, and then from the pump outlet, the outflow discharge tube. At this time, in the leaves at the center of the vacuum area of low pressure liquid was thrown to the surrounding formation there is no air and no liquid, liquid pool at the surface of the liquid under the action of atmospheric pressure, through the suction pipe into the pump, the liquid is continuously pumped up from the liquid pool is also continuously from the outflow discharge tube.Basic parameters of submersible pumpIncluding flow, lift, pump speed, matching power, rated current, efficiency, diameter and so onSubmersible pump main application and scope of applicationIncluding construction, construction, drainage, agricultural irrigation and drainage, industrial water recycling, urban and rural residents cited water supply, and even rescue, disaster relief and so on
- Q: What is the relationship between the minimum suction vacuum of a pump and the required cavitation?
- Suction is allowed to pump the vacuum from the distance from the inlet, which is part of the field installation.The manufacturer of cavitation allowance is closely related to the design and process of pump. Estimation formula: cavitation allowance =10.33 meters - allow suction of -0.5 meters (safety).
- Q: What is the "variable" of a variable pump? Is the displacement change or the flow change? Thank you
- There are many ways to change the variable pump flow: by changing the eccentricity to change the piston stroke length (radial piston pump, the frequency change principle) motor speed to adjust the flow (such as gear pump flow control principle).
- Q: What is the liquid pump? What are their categories? What are their strengths and weaknesses?
- The liquid pump can be filled with oil, water and chemical medium. The gas drive range of the liquid pump is 1 to 10bar (14.5-145psi). The bottom piston is controlled by a two position four pass pilot valve.
- Q: How many square cables does the submersible pump for 7.5KW need?
- According to current I=13A, it is estimated that the cable is less than 10 square meters, so the cable cross section can be calculated at the ampacity of 5A per square meter. The square section of the cable is =13/5=2.6 square. According to the specifications series, optional 2.5 square aluminum cables. When the cable is longer, it is safer to choose 4 square aluminum cables.
- Q: How accurate is the metering pump?
- Three automatic compensation valve device widely used in diaphragm metering pump, especially with suction height requirements, can only be used by three separate Fujian (safety valve, discharge valve and oil supply valve) compensation device.
