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.

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:What are the constant pressure pumps?
- Constant pressure pump is also called the booster pump, the name is used for booster pump, its main purpose is water heater booster, with tall low pressure, sauna, bath and other pressure in the apartment, the lack of water pressure, solar automatic pressurization and so on.
- Q:Why is the flow of the pump too small will occur cavitation phenomenon?
- This is because the impeller of the centrifugal pump rotating speed under the drive of the prime mover, when the valve opening decreases, flow rate is too low, can not be taken away by the friction heat generated by the impeller and the liquid completely, make the temperature of the liquid inside the pump. Thus causing liquid vaporization, forming cavitation. Especially in the power plant, the boiler feed pump is more remarkable. Therefore, when throttling regulation, we should set up recirculation system, increase the output flow of the pump to prevent cavitation. When the feed water rate is reduced to 1/3 of the maximum flow rate, the recirculating gate shall be opened so that the flow of the feed pump will be increased properly to ensure that the liquid temperature in the feed pump does not rise.
- Q:Why does the centrifugal pump close the pressure to start?
- Therefore, the operation rules of multistage centrifugal pumps require that the inlet valve be opened before opening, and the outlet valve is closed. However, the export valve closed time can not be too long, because at this time the medium in the pump cycle, the medium temperature gradually increased, easy to cause mechanical seals, due to lack of lubrication friction and wear or damage.
- Q:What is the difference between centrifugal pump and positive displacement pump?
- The centrifugal pump is usually driven by an impeller, and the head has a functional relationship with the flow rate. Positive displacement pump is gear or piston drive, each stroke output flow is constant, and the head does not matter, the pressure head can be infinite.
- Q:How to install, operate and maintain the pipeline booster pump?
- Should be "People's Republic of China network security law" requirements, since June 1, 2017, the use of Internet services to carry out real name authentication account. In order to ensure your Baidu account can be used normally, please check the account number as soon as possible. Thank you for your understanding and support.How to install, operate and maintain the pipeline booster pump?Brother Yao s Gc76 2547 | browseRecommended for 2016-12-01 23:52:54 best answerThe installation of booster pump must be installed horizontally or vertically according to the installation method. The direction of flow shall be consistent with the arrow on the pump body, and installed as far away from the water level as possible. A valve shall be installed on the pump inlet line for ease of use and maintenance. When the impeller is the aspiration level below the pump on the pump shaft end or around the pump should be installed check valve, the outlet is connected with 13 links for water use, at first use to pump should be filled with water, and tighten the screw plug. The pipe connection should be tight, especially the water inlet pipe can not leak, otherwise it will reduce the pump head or not pumping water. The pump cavity is not water, not a long time running, so as not to damage the seal
- Q:What is the function of the heating pump system for the water pump design?
- As the feed water temperature is higher, in the case of non warm pump start, will make the pump body is subject to greater thermal impact; in addition, the flow components with the pump contact heating fast, not contact with water directly heating slowly. This expansion due to uneven speed, it will inevitably produce thermal stress, deformation of the pump body, sealing surface, the joint surface is lax and leaking phenomenon. Therefore, the warm water pump system is designed for the water pump.
- Q:What is the pumping property of concrete?
- Under a certain pump pressure, the farther or higher the concrete can deliver, the lower the probability of clogging, the better the concrete pumping performance.
- Q:Brief description of centrifugal pump on / off operation
- (3) check whether the turning rotor is easy and flexible, check the pump body is clang or friction sound.(4) the protective cover is installed, and the shield contact.(5) clean the pump frame and do a good job of sanitation.(6) open the inlet valve, make the liquid full of pump body, open the vent valve, clean the air and close it. If the hot oil pump, it is not allowed to open the air valve exhaust, to prevent hot oil channeling spontaneous combustion, if there is a dedicated vent pipes and tanks, you can vent the pipe line air and cold oil.(7) the hot oil pump should be preheated slowly before starting. Especially in winter, the pump body and the pipe should be preheated at the same time, so that the temperature difference between the pump body and the conveying medium is below 50 centigrade.(8) the oil must be sufficiently dehydrated before being introduced into the oil pump.
- Q:What is a positive displacement pump? He Weizheng displacement?
- The principle and structure of positive displacement pumps are similar to those of hydraulic motors. Positive displacement is the pump outward to provide flow and pressure, that is, conventional pumps. A negative displacement pump is a hydraulic motor that rotates by external pressure and flow.
- Q:Working principle and diagram of axial piston pump with pressure compensation variable
- Working principleThe main part (see section structure) the transmission shaft drives the rotating cylinder, the plunger seven uniform distribution on the cylinder to rotate around the shaft center line through the center of the spring will be slippery boots column components in the variable pressure in the head (or swash plate). In this way, with the rotation of the plunger cylinder for reciprocating motion complete, oil absorption and oil pressure action.
