Centrifugal sewage pumps are used to transport sewage and untreated waste water (eg raw waste water). They are most commonly used in municipal wastewater treatment plants, but are also used in buildings and private homes that cannot be connected to municipal sewers due to the natural slope of...

Submersible slurry pump with agitator The wet end parts of the submersible slurry pump with agitator and reamer are made of high wear-resistant alloy by precision casting. It is an integrated structure of machine and pump, small volume, flexible movement, wear-resistant and durable, and can work...

When dismantling: 1. Before dismantling the thrust bearing, use a dial indicator to measure the balance disc clearance and make a record; 2. When the multi-stage pump is dismantled, the parts must be marked in the original assembly order to avoid confusion during reassembly , wrongly installed;...

What materials are generally used for pump bearings? Metallic material Commonly used sliding bearing metal materials in metal materials are bearing alloys (also known as babbitt or white alloys), wear-resistant cast iron, copper-based and aluminum-based alloys. 1. Bearing alloy The main alloy...

How can sea water corrode stainless steel pumps? Many people give priority to stainless steel pumps when pumping seawater or saturated salt water. They feel that the stainless steel is durable and will not require any maintenance, but it is found that the damage is faster when used, and the...

Many people give priority to stainless steel pumps when pumping seawater or saturated salt water. They feel that the stainless steel is durable and will not require any maintenance, but it is found that the damage is faster when used, and the stainless steel pump is seriously corroded. In fact,...

Multi-stage pump is one of the most commonly used equipment in pump, pump and valve machinery. We must understand its performance and working principle before selecting a model. The structure and working principle of multi-stage pump are introduced below. 1. Definition of multi-stage pump...

Stainless steel impeller double suction pump As an important form of centrifugal pump, it is widely used in engineering because of its high head and large flow. The impeller of this pump type is actually composed of two back-to-back impellers, and the water flowing out of the impeller flows into...

High lift pumps cannot be used at low lifts. Before purchasing a water pump, many users think that a pump with a higher head should be selected for a lower head and a wider range of head can be used. In this misleading misunderstanding, when buying a water pump, the pump head selected is very...

Analysis of the causes of water pump vibration 1. The reason for the vibration of the pump There are many reasons for the vibration of the unit and the pump room building, and some factors are both connected and interacted. To sum up, there are mainly the following four reasons. 1.1 Electrical...
