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.

The diesel engine (can be equipped with a clutch) is combined with the fire pump through a highly elastic coupling to form a fire pump unit. The unit also includes diesel tanks, cooling water tanks, fans, control panels (for automatic units) and other components.
