Product overview

KWFB series sealing automatic self-priming pump, it is my company after repeated research of domestic and foreign similar products developed product. This product has the heat resistance, pressure, wear-resisting, "a drainage, life-long self-priming" and other functions and advantages. Under certain conditions can replace long axis pump, submerged pump, submersible sewage pump, etc. In the oil, electric power, chemical industry, steel, medicine, coking, electroplating, environmental protection, fire protection, municipal, water purification, national defense, textile printing and dyeing, mining beneficiation, widely used in civil construction and other industries, well received by users.

Application field

Product features

1, the use of the optimization design "polyhedral centrifugal pump with a serial type dynamic sealing device", abolish the traditional pump packing seal, mechanical seal, completely uniform "run, run, drip, leak.

2, in the operation of the seal friction, long service life than similar products more than 10 times, high reliability.

3, increase the outage sealing device, more suitable for frequent starting places.

Q: A residential building with a floor height of 11 stories and a roof height of 33 meters. The height of the water tank is 37.7 meters. The basement is -3.3 meters, only set fire hydrant, fire pump only consider the indoor fire water, fire flow should be 10l/s. Now select a fire pump, concrete should be much traffic, big head, flow determine how? How to determine the head, I hope to say some more detailed, thank you, and there is to explain this question, why is the fire pump lift 120?. Thank you: According to the water quantity form fire flow water supply system fire safety in high-rise building fire hydrant pump lift is 10L/s, accurate algorithm is to say after a simple calculation with each indoor hydrant flow is two 5L/s bolt so to get the most unfavorable point for the calculation unit to calculate the minimum requirements, with the most unfavorable point suppository pressure specifications 0.07MPa, partial loss of the most unfavorable line and the line (according to the equivalent length) and loss (according to the material resistance coefficient), and finally the pump head loss of gravity difference. But we just calculate the construction elevation difference multiplied by 110% to 120% to determine the head {there is a need to know is: conversion head (m), (kg) and MPa kg 1MPa=10 kg = 100m is the vertical water column on unit area pressure conversion

Q: How many millimeters is the diameter of the water outlet of the four inch pump?: Here is a 4 inch inch, not rural, 1 inches =25.4 mm, 4 inches is approximately 100mm, with DN100 pipeline.

Q: What are the ways of hydraulic pumps?: Hydraulic pump is a power component of hydraulic system. It is driven by an engine or an electric motor. It draws oil from the hydraulic tank to form a component of the pressure oil which is sent to the actuating element.

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: Water pump can not be pumped out, how to maintain water?: Water pump does not suck or does not drain:The causes for the valve stuck, part of the blockage of water, high water or water leakage is too high, may also turn right, impeller blockage. After checking through them one by one, can be taken at the end of valve repair, clear blockage and correct steering, cleaning and other measures to deal with the impeller.The purpose of the work is to pump water from one place to another, or increase the pressure to control the mechanical energy into fluid energy.

Q: Does vacuum pump oil belong to dangerous goods?: Is the grease inside? How could it be dangerous goods? Absolutely not!

Q: Is the sewage pump the same as the mud pump?: The upstream return speed of the washing fluid is required to remove the cuttings and rock powder from the drill in a timely manner from the bottom of the hole and reliably carry it to the surface. Through drilling and extraction, mud can be obtained at the bottom.

Q: Is the flow meter in front of the pump or after the pump?: After the flowmeter is placed in the pump, it is better to add a pressure tank or a buffer tank, so that the flow meter will work better

Q: What is the difference between the ground pump and the pump in the commercial concrete?: What you should say here is the concrete pump.Ground pump: the pump will be placed in a position on the site, the pipeline will be sent to the construction of concrete surface,
