Product overview

KCZ standard chemical process pump is based on the absorption of similar products at home and abroad advanced technology, development and design in accordance with the international standard of international standard chemical process pump. KCZ standard chemical process pump structure was optimized by using CAD modular design, novel structure, reliable and good parts interchangeability, advanced hydraulic model, high efficiency, good cavitation, can satisfy the requirements of performance parameters under various working conditions.

Application field

Can be widely used in chemical, petroleum, metallurgy, power station, food, sugar, pharmaceutical, paper, synthetic fiber, water supply, seawater desalination, environmental protection engineering, heating and air conditioning and other fields.

Product features

1, KCZ standard chemical process pump technical conditions in accordance with ISO standards, safety and reliability of the operation of the pump, versatility, applicability is wide and enforcement of the structure of industrial process pump at the same time, after the pull type design, safe and convenient pump disassembling maintenance;

2, adopt CAD modular structure design, component assembly, with series products between parts with maximum interchangeability;

3, adopts the integral casting closed impeller, strong adaptability to the operating conditions, with high efficiency and cavitation performance of the optimal, with a standard back impeller impeller or balance hole, can reduce the axial thrust and seal chamber pressure, prolong the service life of sealing and bearing.

4, the center line of the pump body at the top of the export and pump foot support, has the largest pipe load resistance, large flow high lift pump double volute design of the runner, radial force is small, dynamic deflection is small, the pump running smoothly, pump casing corrosion quantity is big, and have a replaceable wear ring, maximize the corrosion resistance of the pump and prolong the service life of pump;

5, pump shaft rigidity design, choose heavy cylindrical roller and double angular contact ball bearing in pairs, can bear radial load and axial load, the pump shaft overall strengthen rigidity, impeller dynamic balance test and calibration at the same time, the pump running, low noise, small vibration of shaft seal and bearing life is very good;

6, dry structure design, impeller and nuts and sleeves on the shaft, impeller nut and impeller, are seal between the impeller and shaft sleeve, under the condition of normal use, pump shaft do not contact with the medium, is not subject to corrosion medium, further improve the safety and reliability of the pump operation;


Q: Know flow and lift how to calculate the pump power?
P: the density of refrigerant, when the working fluid is water, P =1ETA - pump efficiency, can not find desirable value =0.8N=30x (200/3600) x9.81x1/0.8=20.44 = 20 (kW)(that is, 20kW motors)
Q: How does the centrifugal pump pump and cut the pump?
Can not be generalized, the pump is divided into many categories, centrifugal, reciprocating, screw type, diaphragm type, and so on, the starting steps of each pump is not the same. The following is the centrifugal pump and reciprocating pump to do a simple introduction. Check the items and so on.Centrifugal pump: first open the pump inlet valve, pump exhaust, and then start the motor, slowly open the outlet valve. If it is a high speed motor or multi-stage pump, open the motor before the outlet valve slightly open.Reciprocating pump: slightly open the inlet valve of the pump, fully open the outlet valve. After starting the motor, at the fully open inlet valve.Here is a brief introduction. I hope it works for you.
Q: What are the characteristics of a pipe shield pump?
According to the transmission of liquid temperature, pressure, viscosity and particle level have different requirements, the pump can be divided into the following types: first, the basic type (standard type) transport medium temperature does not exceed 120 degrees, the head of not more than 100m, the pump other types are variations on the basic type and improved.
Q: What is the lift off the dead center point? This is a straight mark about the water pump. What is the function and the relationship between the design head and the pump head? ThanksWhat exactly is the dead point lift? What's the function of this indicator?
The dead point head is the measured head after the outlet valve is closed. Mainly on the lower reaches of the pump equipment, such as your dead center, the lift is 300 meters, that is, 3MPa
Q: What does "efficiency" mean in a water pump catalog?
The efficiency of the water pump nameplate refers to the maximum efficiency that the pump can reach at the rated speed
Q: What is the function of a submersible pump?Do you have any knowledge about submersible pumps?.
Submersible pumpThe submersible pump is composed of a control cabinet, submersible cables, water pipes, submersible pumps and submersible motors.Submersible pump main application and scope of applicationIncluding mine rescue, construction, drainage, agricultural irrigation and drainage, industrial water recycling, urban and rural residents cited water supply, and even rescue, disaster relief and so on.Classification of submersible pumpsAs far as media is concerned, submersible pumps can be broadly divided into three categories: clean water submersible pumps, sewage submersible pumps, sea water submersible pumps (corrosive).
Q: Please give me professionals to calculate, the cylinder bore is 100 and the rate of 20m/s, the leakage can be ignored, but to the large flow pump!
Select the hydraulic pump from the following considerations:1. hydraulic pump pressureHydraulic pump operating pressure is the pump (or motor) in actual work output (or input) oil pressure, determined by the external load.Rated pressure refers to the maximum pressure under continuous running in accordance with the test standards under normal working conditions. The size of the pump is limited by the service life, and the service life of the pump (or motor) will be shorter than the design life if it exceeds the rated pressure. When the work pressure is greater than the rated pressure, it is called overload.
Q: What are the constant pressure pumps?
Chlorine booster pumpThe pressure range of chlorine booster pump is large, and different pump can be used to obtain different pressure area. The input air pressure is adjusted and the output pressure is adjusted accordingly. High pressure can be reached, gas 90Mpa. Wide range of flow, for all types of pumps only 0.1Kg pressure can work smoothly, at this time to obtain the minimum flow, adjust the intake volume can be obtained after a different flow. Easy to control, from simple manual control to fully automatic control, can meet the requirements. Automatic restart, regardless of what causes the pressure drop in the pressure loop, will automatically restart to supplement leakage pressure and maintain constant loop pressure. Safe operation, gas driven, no arc and spark can be used in dangerous situations.
Q: What are the main performance parameters of the pump?
RPM revolutions per minute. In N, the unit is R / minThe power delivered by the shaft power prime mover to the pump shaft. In P, the unit is kW.The ratio of useful power to shaft power of an efficient pump. With ETA said. It is an indicator of the degree of perfection of the pump in terms of hydraulic power
Q: Why can't the centrifugal pump pump the vacuum?
Working principle (taking centrifugal pump as an example):Prerequisites, processes, and requirements for the overall system structure.
