This series of products, compact structure, reasonable, stable and reliable operation; Configuration of special machine sealing structure, improve the operating environment, extend the service life; High efficiency and energy saving, low operating cost, saving management costs; Cover an area of an area small, save construction investment, favored by the market.
Application field
The central heating system of circulating water; Refrigeration, cooling circulating water of air conditioning system
Water treatment, sanitary water; Indoor living water supply, domestic hot water system
Water supply, water irrigation system; Flushing system with water
Product features
1, the pump and motor directly connected, pump shaft completely concentric, small vibration noise is low; Special structural configuration of bearing, impeller cantilever short, operation is stable and reliable
2, the use of forced circulation should not be restricted to the special structure of configuration of mechanical seal, improve its running environment, prolong service life
3, advanced pump chamber and the impeller design, make the pump has the superiority of hydraulic characteristics, ensure the pump efficiency and energy saving, low running cost, cut down the cost of operation management by 50% to 70%
4, unique installation structure greatly narrowed the pump cover an area of an area small, save construction investment from 40% to 60%
5, stainless steel shaft, never rust, guarantee the mating part tear open outfit is simple, reliable mechanical seal bellows seal, maintenance-free, easy to maintain。

- Q: What are the meanings of the vacuum pump, the front pump and the main pump?
- The main pump can be understood as a booster pump, used to improve the vacuum mechanical pump with pumping quantity. As the roots pump, diffusion pumps, molecular pump. These can not use (too much pressure) so the need for mechanical pump drainage, the vacuum chamber is pumped into the rough vacuum, then the main pump starts to work.
- 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: Variable flow pumps are variable pumps
- Yes. The variable pump is designed to change the flow rate
- Q: I would like to ask, constant pressure pump set pressure 20Mpa, the actual load is 15Mpa, then the constant pressure pump outlet pressure? If it is 20Mpa, then where is the loss of 5Mpa? If 15Mpa, the constant pressure pump 20Mpa how to understand? In addition, the constant pressure pump pressure is defined when the flow began to reduce the point, or a sharp drop in flow after the point?
- Constant pressure pump is pressure maintained at the set pressure, flow control valve according to the order, there is pressure to set, after the pump displacement is reduced, as for how to reduce emissions, to see how much you need to flow.
- Q: How to distinguish the flow and displacement in the hydraulic pump? What's the difference between the two?
- The unit of displacement is the milliliter. How many milliliters does the pump rotate per circle? The displacement is the pump, the individual,The unit of flow is generally a liter, a figure added to the displacement of the pump over a period of time,
- Q: What are the main performance parameters of hydraulic pumps?
- Main performance parameters of hydraulic pump: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 is the pumping property of concrete?
- Pumping capacity means that fresh concrete can be transported by concrete pump, and concrete construction can be carried out with high efficiency. 'pumping' is a qualitative statement
- Q: Direct connection pump What is straight pump and non direct pump? What's the difference in structure?
- Direct connected pump: pump impeller installed directly on the motor shaft, it looks like a whole, relatively compact, simple installation, but the general power is relatively small (big bad processing connection, but not absolute);Non direct pump: pumps and motors are independent of each other, through the coupling torque transmission, the structure is relatively large, complex installation, to adjust the level / concentricity and so on, the general power is relatively large
- Q: Because the water pressure of the booster pump is not enough, it can not work automatically. It can only be operated by hand. It is inconvenient to use.
- One possibility is the automatic type household booster pump used for a period of time, automatic failure phenomenon, it is mainly stainless steel and other metal products in pipes, long-term precipitation to shut off the power supply after unloading, unscrew the top screw, remove the plastic sheet to be cleaned, and then, according to the original reset, the normal debugging. Can be re used. But that's not why if your booster pump isn't working properly all the time.
- Q: What's the difference between a centrifugal pump and a centrifugal pump? What are they used for?
- Centrifugal pumps are used to transport liquids (or mixtures, waste water, waste materials) from one location to another.
