What kind of terrain to choose what kind of water pump

This problem, in short, is the selection of water pumps. The following are the applicable way for you to choose water pumps from zjbetter. I hope they can help you choose water pumps and help you better. Choose the water pump that suits your design.
1. Confirm the use terrain
First understand the terrain in which the outfit is used, including temperature, moisture, air pressure, air cattiness, dustproof and leakproof conditions, and the position of dangerous areas.
2. Confirm operating conditions
Refers to the liquid face pressure( absolute) on the suction side of the liquid, the liquid face pressure on the discharge side, intermittent or nonstop work, fixed or mobile position, and the convenience of installation and conservation.
3. Confirm the nature of the medium
Medium temperature, viscosity, density, impregnated vapor pressure, solid flyspeck periphery and content, gas content, cattiness, volatility, trap, toxin.
4. elect the material of the pump bathe corridor
According to the physical and chemical parcels of the pumped medium above, the material of the inflow- passing corridor is determined.
5. Determine performance parameters
The performance parameters of the water pump can be determined by computation, analogy, test and other styles.
6. Determine the installation type
The installation of the channel is determined by the layout of the channel and the installation point, and there are direct connection, perpendicular and other types.
8. Determine the number of pumps
In general, spare pumps, especially fire pumps, are set up, and the number of pumps is named according to different situations.

A fire pump controller manages the operation of the fire pump, including starting, stopping, and monitoring performance. It ensures the pump operates correctly during an emergency and complies with NFPA 20 requirements.

Diesel engine fire pumps can be used for fire water supply in warehouses, docks, airports and other places. We usually choose the appropriate diesel engine fire pump model application according to the head, flow rate, power, medium properties, required materials, etc. provided by the user. In order to avoid mistakes, the loss caused by the installation environment will also be considered comprehensively to ensure stable and reliable efficiency.

Sizing diesel fire pumps involves evaluating factors such as the building’s occupancy classification, area of coverage, hazard level, and required flow rates for firefighting purposes. Hydraulic calculations are typically performed to determine the water demand and pressure requirements, which are then used to select a diesel fire pump with the appropriate capacity and performance characteristics. It’s essential to work with qualified engineers or fire protection specialists to ensure that the pump is sized correctly for the specific application.

The multi-stage fire pump consists of two parts: the motor and the pump, and the motor and the pump are coaxial. The structure of the pump consists of pump body, impeller, pump cover, mechanical seal and so on. The inlet and outlet of the pump are on the same horizontal axis and have the same caliber specification, so the loading and unloading is very convenient, and the floor space is small. The pump is fitted with a base for easy installation and increased pump stability. It is used to transport clear water without solid particles, liquids with physical and chemical properties similar to water. It is mainly used for pressurized water delivery in fire protection system pipelines, and is also suitable for industrial and urban water supply and drainage.

The integrated electric fire pump unit combines system integration with intelligent control, offering high efficiency, safety, energy savings, and easy maintenance—ideal for high-rise buildings, industrial facilities, and modern fire protection systems.

Learn what a fire pump test header is, how it works, and why it’s a key component for performance testing and NFPA 25 compliance.
