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: What is the dry running protector of screw pump? What's the principle and function? Thank you: When the temperature reaches a certain value, the signal is transmitted to the electric control box through a dry running protector, and the electric control box is used to stop the screw pump so as to protect the screw pump.

Q: What is cavitation, centrifugal pump cavitation phenomenon how to solve?: Centrifugal pump cavitation phenomenon how to solve?:Measures to improve cavitation resistance of centrifugal pumps(1) improve the design of the suction port of the centrifugal pump to the impeller. Increase flow area; the radius of curvature increases the impeller cover inlet section, reduce the flow accelerated sharply with pressure; reduce the thickness of the blade, and the blade inlet rounded, close to the streamline, can also reduce the acceleration and pressure flow around the blade head portion of the impeller and the blade inlet part; improve surface finish in order to reduce the resistance loss; the blade inlet edge extends to the impeller inlet, the liquid flow in advance to accept work pressure, improve.

Q: Is the vacuum pump air compressor?: A vacuum pump is a device or device that uses a mechanical, physical, chemical, or physical chemical method to pump a vacuum from a container to be evacuated. Generally speaking, a vacuum pump is a device that uses various methods to improve, produce, and maintain a vacuum in a confined space.

Q: Concrete pump 125 pipe wall thickness: Currently mainly divided into gate valve, concrete pump and S valve concrete pump. Another is a pump consisting of a pump body mounted on an automobile chassis and fitted with retractable or bent cloth poles

Q: Operating procedures for measuring pumps: First, preparation and inspection before starting1. Check to make sure that the drain line is equipped with a safety valve with the correct set pressure.2. Check the screws for the liquid end parts.

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: 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 many concrete pump tube diameter: Different pipe diameter is different, most of the 125, there are 150. Now we have the smallest pump on the market, with a pipe diameter of 100.

Q: What are the main performance parameters of the pump?: The amount of liquid supplied by a pump in unit time. Volume flow Q, unit m3 / s. There is mass flow G, unit is kg / s.

Q: Does the control cabinet of the fire control pump need to be related to the fire control room?: Normal words are needed, but when you check and check, has anyone checked?
