Yesterday, Modo® Pump successfully completed an important export business and delivered four sets of high performance multistage pumps to Russia. These 4 multistage pumps are made of cast steel material, which has higher strength and better toughness compared to ordinary cast iron material....

The function of the check valve at the outlet of the centrifugal pump is to prevent the backflow of the liquid in the outlet pipeline from forming water hammer and causing damage to the impeller in the pump. The installation of the check valve has nothing to do with the number of pumps. The...

If the inlet liquid level is too low, it is easy to generate eddy current, suck in air, cause cavitation and reduce the flow head; 2 The water inlet pipe of centrifugal water pump or water inlet is blocked by foreign objects, resulting in a decrease in the flow head; 3 The temperature of the...

After the stainless steel chemical centrifugal pump stops running, the inlet valve of the pump should be closed, and the valves of the auxiliary system should be closed in turn after the pump cools down. 02 The high temperature pump should be stopped according to the provisions of the technical...

When pump cavitation occurs, the impeller suffers cavitation damage, affecting pump performance and preventing its normal operation. For this reason, the theoretical basis for improving the anti-cavitation performance of the pump is briefly described below, and the geometry of the impeller inlet...

How much do you know about the types of pump casings? The pump housing is used to isolate the pumped medium from the atmosphere to prevent leakage and maintain pressure. For centrifugal pumps, they "wrap" the pump rotor, which transfers energy to the pumped medium through an impeller...

According to ISO8044 and VDI3822, corrosion is the reaction of a metallic material with its surroundings, which in most cases is an electrochemical reaction that occurs only in the solution of an electrical conductor (electrolyte). This is called a redox reaction because two reactions occur...

Why does stainless steel also rust? When brown rust spots (spots) appear on the surface of stainless steel pipes, people are amazed: "Stainless steel does not rust, and if it rusts, it is not stainless steel, and there may be a problem with the steel." In fact, this is a one-sided...

The fire pump is the heart of the fire water supply system. During the duration of the fire, the safety of personnel entering and leaving and the normal operation of the fire pump have strict regulations on the setting of the fire pump room. Today, we have sorted out the relevant content of the...

3’’ high head portable self-priming water pump Main Data: Low noise: the nearly ideal combustion chamber reduces the operating noise; Low vibration: strict balance configuration ensures smooth operation of each power unit; Multi output: multi type and multi speed power output provides Zui great...
