Several common control methods of diesel fire pump
Using its own advantages, diesel fire pumps can be widely used in environmental protection, water treatment, fire protection, and other departments to transport various liquids.

Common materials for pumps
Gray cast iron is the most commonly used type of cast iron, and the national standard code is ht. Generally, this material is used for the pump body, impeller, pump cover, and suspension of clean water pumps (diesel engine water pumps), and three brands are commonly used: ht150, ht200, and ht250. The ht150 is used for non main components such as bases and gaskets, the ht200 is used for pump bodies, pump covers, suspensions, etc., and the ht250 is used for impellers, mouth rings, shaft sleeves, etc. Different countries have different manifestations of gray iron. For example, the Japanese code is fc, the German code is gg, and the United States is first-class.

Methods for selecting and purchasing diesel engine water pumps
1. Select a diesel engine water pump that meets the lift requirements The so-called lift refers to the required lift, rather than the height of water lift, which is particularly important for selecting diesel engine water pumps. The lift of the diesel engine water pump is about 1.2 times the water lifting height. If the vertical height of the source and water is 20 meters, the required lift is approximately 23 to 24 meters.
